Please note that due to limited stock, this deal will remain active subject to stock availability. Some flavours may sell out and I will keep this deal updated.

Also, you will get the store credit just so long as you order 4kg of WPI (or more). You can order anything else on top of this and you will still receive the bonus credit amount.

WPI Flavours

We have even more flavours with a total of 20 flavour options!

We have improved most of these flavours in the last few months, in case you haven't tried our WPI in a while.

All flavours are naturally sweetened. Some use stevia, others use thaumatin as follows:

Stevia: Cinnamon Icing, Aussie Choc Malt, Mango Sorbet
Thaumatin: All others except unflavoured

Our newest three flavours: Matcha Green Tea Ice Cream, Coffs Harbour Choc Banana, Chocolate Peanut Butter

You can backorder flavours in this deal and we will ship once they are produced. Some flavours will have longer delays, as we are waiting for the flavour ingredients to arrive to us.

Product Breakdown

  • 100% Australian Made
  • Per serve: 29.1 - 24.4g protein / 0.3 - 0.9g fat / 0.4 - 3.4g carbs (varies between flavours)
  • We only use WPI in this protein - this is not a blend
  • Protein is added hormone free, ultra and micro filtered and cold pressed
  • Soy free - we use sunflower lecithin instead of soy lecithin (soy is common in whey proteins)
  • Manufactured in our own NSW Licensed Food Facility in Sydney
  • Backed by our 110% guarantee. Try it and if you don't love it, we'll give you 110% back (in store credit) or a full refund (including delivery). As I mentioned in the video, we offer this so you can try the product risk-free. If you've opened it up to try it we're not going to make you send it back either.

Other Notes/Common Questions

  • Choose Multiple Flavours: We pack these into 1kg pouches. Choose the multi-flavour option for 4 different flavours!
  • Packaging: All our WPI now has the new zipper packaging.
  • Nutritional Information: To view the full nutritional panel, just click on the "NUTRITIONAL INFO" tab on the page and then select the flavour.
  • Best Before Dates: Best before dates will be 18-24 months away. We turn this product over very quickly so all current stock has been produced recently.
  • Free Delivery: You will get free delivery on your entire order when you order any Amino Z or Bandito Labs supplements.
  • Applying Store Credit: To apply existing store credit (Z Points), at checkout, select the option in the "Payment Section" to apply your Z Points. Make sure you are logged in.
  • 30% Discount: The 30% discount will be off the full price before discount, not on the already discounted price.
  • Receiving Store Credit: Store credit is assigned as "Z Points" to your account within 1 week after your order ships. It can then be applied to any future order that you place.
  • Store Credit Limit: There is a limit of $50-$65 bonus store credit per person during the promotional period. You can order more than 4kg of WPI, but the store credit will be capped so we can stay in business!
  • Other Store Credit Info: Store credit does NOT expire. Also, you do NOT have to be a Club Z member to retain your store credit.
  • Club Z: Our Club Z membership program is a paid subscription with the most common membership being $9.99/month with $10 back/month for each monthly renewal. This is different to having an account on our website. We frequently run Club Z bonus offers, such as in this deal where anyone who was already an existing paid Club Z member (prior to launching this promo) will receive a bonus $15 back in Z Points. Full info here.
  • Referral Codes: Please note that this offer won't stack with our referral code offer.

A word of thanks

We had an overwhelming amount of support for both Black Friday and Boxing Day, despite the impacts we have all felt from inflation. Thank you to everyone who purchased, upvoted and/or engaged with me or Vanessa during that time.

Also, thank you to everyone who has emailed me directly, or messaged us with feedback and/or asking for us to run another deal. This continues to remain a priority for us. We continue to receive amazing feedback and are striving to continually improve as a result.

As always, I will continue to engage via this forum and email because there is always room for improvement. Vanessa will be helping out with the private messages. Thank you to anyone who takes the time to help out!

Any questions please ask!

Amino Z (Owner and Deals Guy)


27 Feb 4:38PM: Matcha Green Tea is now on backorder. We are producing more stock tomorrow, so at this stage your order will only be delayed by 1-2 days if you order this flavour.

27 Feb 6:39PM: A few flavours are likely to go into backorder overnight. Flavours at risk of going onto backorder and their delays are as follows: Choc Mint (3 days), Strawberry (1 day), Choc Caramel (2-3 weeks). Coffs Harbour Choc Banana (around a week), Mango and Choc Peanut Butter once sold out cannot be backordered. I'll be stepping away from the computer for this evening, please PM us if you run into any issues (eg. order problems or requests) and otherwise I'll be back online tomorrow to respond to everything. - Jay

28 Feb 9:32AM: This deal has gone bonkers, thank you to everyone for the overwhelming support! Many flavours are now critically low on stock as we underestimated the volume of orders we would receive. Some flavours are either now sold out, on backorder or about to sell out. I have added estimated wait times on a per-flavour basis. Mango has now sold out completely. Grenade spreads are sold out too. I'll try to keep this page updated as best as I can. - Jay

28 Feb 2:04PM: Matcha green tea ice cream is back in stock. Iced coffee now very low on stock, if it runs out, we will have more produced in a couple of days. - Jay

28 Feb 4:27PM: Aussie Choc Malt is back in stock. Chocolate Caramel is now on backorder. It can still be ordered under this deal, but ETA is likely 2-3 weeks for dispatch. - Jay

28 Feb 6:13PM: We have all hands on deck to ship out these orders. Most orders placed yesterday have been shipped, however we are still packing some. You may experience a 1-2 day delay in dispatch while we catch up on the packing due to the sheer volume of orders. Thanks so much for your patience and the overwhelming support for this deal! - Jay

1 Mar 8.40AM: Iced coffee is now on backorder, but more stock being produced today. Cinnamon icing is now very low on stock but can be backordered with a short delay of 1-2 days. New orders may take up to 2 days to ship due to current order volumes, but we are frantically catching up today! - Jay

1 Mar 11.05AM: New orders for iced coffee may incur a delay of around 1 week. More stock is still being produced today for all existing orders, so all current orders will have a minimal delay. - Jay

1 Mar 2.18PM: Strawberry and iced coffee are back in stock, but iced coffee is about to sell out again. If on backorder, your order may take about a week to be sent (we're waiting on an ingredient delivery). We are still behind on packing orders by 1-2 days. - Jay

1 Mar 5:20PM: Cinnamon Icing is now on backorder, more to be produced in the next day or so, so there will be a minimal delay. Iced coffee is now on backorder, with a delay of approximately 1 week for new stock to be produced and shipped out. We are still behind on packing orders by 1-2 days. Thanks so much for your understanding while we catch up! - Jay

2 Mar 9:48AM: Cinnamon Icing will be produced today, so only a minimal delay for backorders on this flavour. More Iced coffee will be produced today for anyone currently waiting on a backorder. We're also going to be catching up on most other backordered products (eg. Some Pre Workouts) tonight. Our customer service is behind by about 1 day on emails/SMS, but please message Vanessa by PM for anything urgent (eg. order changes). The warehouse is beginning to catch up, but please continue to expect a 1-2 day delay in dispatch. We have put on more people again today to catch up with the packing (including Kristy our social media person and myself) as getting these orders shipped remains our top priority. Consequently, I'll be away from the computer today while helping the warehouse with orders. - Jay

2 Mar 4:52PM: Cinnamon icing is back in stock. Iced coffee has been produced today, but has fallen back into backorder due to very high demand. Our warehouse is catching up and we're seeing dispatch now within approximately a day from order. Please continue to PM Vanessa for any urgent order changes. - Jay

3 Mar 9:48AM: We are back up to date with orders! All orders now shipping within 1 business day. Thank you to everyone for your patience if your order did incur a delay. Customer service emails/SMS are currently 1-2 days for a reply and we are continuing to catch up (our target is ~1 hour). For anything urgent (eg. order modifications, address changes etc), please PM Vanessa so we ensure your order is caught before it's packed off. - Jay

4 Mar 11:23AM: Strawberry is almost sold out, please note if you backorder this it will incur a length delay of 4-6 weeks while we wait for more flavouring to arrive. Orders are being packed over the weekend and all new orders should ship within 1 business day. Customer service is still about 1-2 days behind on email/SMS so please PM Vanessa for any urgent order changes (product changes, address change etc). - Jay

5 Mar 10:10AM: Strawberry is now on backorder and will incur a delay of approximately 4-6 weeks if you receive a backorder notification. We will do everything possible to fulfil any backorders sooner than this, but if you would like to change flavours please just reach out to our team. Also, we have now exceeded 400 upvotes, making this deal our most popular supplement deal ever! Thank you to everyone for the amazing support!! - Jay

6 Mar 9:51AM: Smooth milk chocolate is about to run out and go onto backorder, but more stock will be made this week. Also, we have received a number of requests to extend this promotion and we have modified the deal to end today for anyone who wanted to take advantage last minute. We now have extremely low stock levels and won't be able to push this out any further. Thank you everyone for the support of this deal!! - Jay

  • Just in time. Thanks Jay

    • No worries and thank you! I really appreciate the support!


      • Hi Jay,

        Are we still getting the $50 credit if we have other products at the cart?


        • Yes you will. So long as you order the 4kg (or more) of WPI, you'll get the store credit added within a week of your order shipping out.


          • @aminozcomau: Sorted. Thanks again. More cheap gains for me.

          • @aminozcomau: What is the country of origin of the raw whey itself, where the cows pastured?

            • @chyawala: USA, Wisconsin specifically. The Whey certification is on their website

              • +1

                @ShrewdBargin: Previously it was Au/NZ whey. Dairy in the USA has no regulations that are checked or enforced.

            • +1

              @chyawala: Confirming yes, we source our protein from USA presently. We also test the raw materials upon arrival against the reports provided.

    Damn it! I just ordered over the weekend :(.. Missed out on $65 credit.

      Feel free to PM us, I'll make sure Vanessa looks after you. As an ongoing customer I want to make sure you're looked after mirovich.


      • Thanks Jay! I placed an order for 4KG WPI on Saturday.
        Just PM'd :)

        • +1

          No worries, thanks as always for the ongoing support of the brand.


  • Praise the lord!!

    • Thanks for the upvote currentfad!

    Lets load up on Horny Goat.

  • Hey Jay, I literally ordered 4 x 1kg WPI's last week, any chance for backdating this awesome deal for the Oz Bargain customers?

    • +7

      Feel free to shoot over a PM. Vanessa will look after you :)


  • +3

    Wow we even got our own YouTube video this time! Legendary company.

    • +2

      Thanks for the upvote and support JHoliday. Please don't mind the production quality, literally just my phone and mic under office lights.


  • +1

    Still got some left from the last deal, good stuff Jay & team!

    • Thanks for buying from us previously astroman! I hope you like the WPI.


  • Thanks op!

    Any way to get one each of the spreads? Tried to switch but couldn't…

    • We have a handful left in the choc hazelnut, please PM us and we'll make a change manually.

      For anyone else who wants choc hazelnut, feel free to message us. Though stocks are very low in this flavour, we may sell out very soon, so will prioritise based on earliest message.

      Both are BB end of Dec 2022 FYI.

      Thanks for asking bemybubble!


      • Thanks Op - I put a note in the order - will that suffice?

        • It should do, but to be safe, please PM Vanessa your order number so it 100% doesn't get missed. Thanks in advance.


  • +1

    How do these guys compare to Bulk nutrients?

    • +7
      • Amino Z use a zipper locking mechanism for their bags. Bulk Nutrients use the standard press to seal for their bags.
      • Amino Z do not charge for shipping after you reach a certain threshold. BN charge you flat rate regardless of how much you spend.
      • There isn't too much difference in quality between the two companies. I recently switched over to Amino Z and have no complaints. However, I do wish Amino Z bags had the press to seal function.

      Regretfully, I made an order yesterday so I missed out on today's deal.

      • +1

        Thanks for the comparison. I’ve been a buyer of the BN Protein Matrix+ blend for a lifting/daily breakfast protein for a long time. Seems they don’t have a replacement for that.

      • +2

        try messaging, read rep comments above, person might get offer anyway

      • +2

        Feel free to PM us fantess94 if you just placed an order, Vanessa will look after you.


    • Thinking the same thing. I usually buy WPC not WPI, but regardless they are a little more pricey. Wondering if that is reflected in the macros/quality/taste.

  • +1

    Thanks Jay and team

    Any idea if flavour samples are coming back? Keen to test some of the other/new ones without committing to a 1kg test 🤣

    • Thanks for asking Unorthodox. We've got a handful of samples available at https://www.aminoz.com.au/amino-z-whey-protein-isolate-singl…

      We're working on getting samples across most of our range since we've significantly improved the flavours in the last few months.

      But failing that, we do have our 110% Guarantee if you get a flavour you don't like.

      Thanks also for the support and upvote.


  • Thanks Jay! How did you know my supply from the Black Friday sales was just about to run out!

    • Haha no worries! Thanks for coming back!


  • +1

    I still have 6 unopened bags from the previous deals, would have jumped on if I didn't have so many!

    • Thanks so much for the past orders and for the upvote too!


  • Ah bugger, tried to hold out for a deal as long as i could but just placed an order last week :(

    Mango Sorbet, Iced coffee and Choc malt are my fav. Coffs harbour choc banana is also amazing

    • Thanks so much for the recent order and for supporting the brand! I'm so glad you enjoyed the new choc banana we released, I'll pass that on to the team.


  • +2

    Amino Z is one of the best Aussie companies. Have been an Amino Z member for over 12 months and its fantastic.

    Great deal Jay.

    • Thanks so much for the kind words Jr64!


      • No worries - I wanted to ask, is Oz Choc Banana (from a prior deal) the same as Coffs harbour choc banana?

        I still have 3x bags left from the last deal, and wanted to ask when the expiry date is for this batch WPI?

        • It's a different flavour Jr64, we reformulated it with a slightly different flavour profile and to use thaumatin instead of stevia, as stevia leaves a bitter aftertaste that some people don't find pleasant.

          This batch best before will be 18-24 months away.

          I hope this helps!


          • @aminozcomau: Is there a list of the flavours which are thaumatin based somewhere?

            • +1

              @x3midget: Hi x3midget, yep I've included it above in the original post. But here for reference:

              Stevia: Cinnamon Icing, Aussie Choc Malt, Mango Sorbet
              Thaumatin: All others except unflavoured

              Only a few contain stevia, most are now thaumatin. I hope this helps.


  • What's the expiry date on the WPI Jay? Cheers.

    • +1

      Hi jje, it should be 18-24 months. It's all fresh stock. Thanks for asking.


      • Awesome, stocking up then! Cheers

        • Awesome thanks jje!


  • Hey Jay, can you add the $50 Credit for buying creatine as well?

    • So long as you order the 4kg of WPI, you'll get the credit irrespective of anything else you order. So you can add the creatine onto the order too, you'll still get the credit. I hope that helps!


  • +1

    Supporting businesses from the Shire :-)

    • Born and raised! Thanks for the support!


  • Amazing deal again, thank you!

    I have not yet finished the protein powders from the last deal, so i got some explanation to do to my mrs, that this is a good deal. Wish me luck.

    • Haha, I can relate! Thanks so much for the support and good luck with that one!


  • I ordered 5kg of WPI around two weeks ago and still waiting for delivery (was waiting for flavour that was out of stock), am i able to claim the $65 worth of Z points? Thanks

    • Hi Nicles, oh sorry about the delay on that order due to the out of stock flavour. Yes, I think that's only fair. Please PM us, Vanessa will sort this out for you.


  • +1

    Hey @aminozcomau I ordered a Vanilla Creamy WPI 1Kg bag last deal and got it a couple of days ago. When I opened it up, it had chocolate flavoured powder in it. My first ever order from you guys so naturally I was like wtf lol

    I took photos and was going to email about it, but since you're active here might as well ask - what's the go from here? Can I get a refund or a new bag of what I actually ordered?

    • +1

      Thanks for bringing this to my attention Litew8baby. We'll take of that, it's likely a labelling issue which we'll have to look into internally.

      Could you PM your order details to us, along with the batch number? We'll just send out a replacement as a priority. Vanessa is handling the private messages and I'll give her a heads up on the matter. I'll also follow this up with her.

      Thanks in advance.


      • Thanks for quick response.

        I have order number, but where do I find batch number?

        • @Litew8baby it should be on the product itself, likely on the back, near the best before date.

          Thanks in advance.


  • @Jay - which are your top 5 selling WPI flavours?

    • Hi again pyramid, thanks again for the upvote!

      Top 5 are: Aussie Choc Malt, Chocolate, Vanilla Creamy, Smooth Milk Chocolate and Iced Coffee. I must add, we just released 3 new flavours which are super popular right now (Coffs Harbour Choc Banana, Matcha Green Tea Ice Cream and Chocolate Peanut Butter).

      Thanks for asking.

      Feel free to PM us Jinx, Vanessa will look after you :)

      Thanks for the order and supporting our brand.


  • Tried signing up for an account by it's taking crazy long for the email verification to come through.

    • If you're having issues, please PM us and Vanessa can look into it. I'd allow up to 5 minutes or so, but if still nothing we can do it on the backend.


      • Pm sent

        • Thanks nightelves.


  • Top 5 most commonly ordered/enjoyed flavours? Keen to try some but I want the most common.

    • Hi Veela,

      Top 5 are: Aussie Choc Malt, Chocolate, Vanilla Creamy, Smooth Milk Chocolate and Iced Coffee. I must add, we just released 3 new flavours which are super popular right now (Coffs Harbour Choc Banana, Matcha Green Tea Ice Cream and Chocolate Peanut Butter).

      I hope this helps!


  • +3

    These guys are such a standup business! I still remember the time I ordered 4kg tub of protein on sale, they sent me 5 X 920g instead to compensate and apologised that the 4kg was out of stock (effectively 600g for free)

    Everytime I've contacted them for help they always reply, and always help with a postage or product issue with great after sales support.

    • Thanks so much for sharing that DR-JEKL! I really appreciate the support and I'm so happy to read that our team looked after you! I'll pass this along to our customer service team, they are a true asset.


  • AWESOME deaal Jay! is this a new batch or the BLACKFRIDAY batch? is there a deal for more than 4kg?

    • Thanks traichung! This is all new stock, we are well and truly through the stock we manufactured for Black Friday last year.

      If you order more than 4kg, you'll get the extra items at the same discount per unit, but no additional store credit. Just make sure you order either 4kg or 1kg sizes to get the correct unit price. It won't be applied to 3/5/10kg size options.

      I hope this helps!


  • Thanks Jay, perfect timing :)

    • Awesome, thanks for the support oxblood8!

  • My 5th order with you guys and I used my points to make it even cheaper. Thanks Jay and happy birthday to Amino Z!

    • Oh wow nice, thank you for order #5! Thanks so much Vavoom!


  • Just brought 8 x1 KG 2 weeks ago on the weekend……
    Any chance of back-dating?

    • Feel free to shoot through a PM, Vanessa will be able to look into this for you. Thank you and I really appreciate the support kenjai!


      • Awesome, had to say the new limited time flavour is great! Hope they stay!

        • Oh awesome, thanks for the feedback! I'm glad you've been happy with it!


  • Hey There,

    Is this vegetarian suitable?
    What is the source of the rennet used?


    • Thanks for asking parallelparadox. The protein is whey, so it is derived from cow milk. For the rennet specifically, this is something I'm going to have to check with our team with (possibly the manufacturer of the raw material). I'll revert back once I have a firm answer for you.


    • +1

      @parallelparadox we just received word back, the rennet is microbial, no animal rennet is used.


  • Been ordering from AminoZ for quite some time now. I ordered and tried their new matcha flavour just the other day - it's pretty good. Although for me it's a tad too sweet. I might try to mix it with some matcha powders and see if it helps. :)

    • Yea brought 2kg of Matcha, they are awesome. Hopefully this flavour will stay.

    • +1

      Thanks for the feedback and for the support of the brand!

      A few people did mention to me they added a bit more matcha. We'll be taking on board any feedback on this new flavour.

      So far matcha has been popular for us. We have been running it as a limited edition flavour, but if it's that popular we might keep it :)

    Hi Jay, are Amino Z supplements listed on the ARTG as per these legislative changes in 2020? Not saying they're not, but can't see any indication on the product pages you've linked.

    • +2

      Thanks for asking Ordinance.

      No, we don't currently have our supplements listed on ARTG. This is something we're looking into for the capsules (to be implemented by November this year).

      This isn't my area of expertise but this is something we're currently investigating.


      • +1

        Thanks Jay. I should have noted in my original comment that there is no legal requirement for retailers to list their supps on the ARTG until November 2023. That being said, I'm much more likely to purchase ARTG listed supps knowing that the TGA has tested them for quality and safety.

        Also, considering the amount of research your team has done to establish the efficacy of your supps, I'd highly encourage them to look into having them assessed by the TGA for efficacy as well as quality and safety. This is a relatively new process offered by the TGA for supplements with scientific evidence for their efficacy without having to go through the rigmarole of having them registered as official medicines. You can read more about it here.

        • +3

          Thanks Ordinance, this is super helpful. I'm going to pass this along to our product developer as I feel this could be of particular value to us given the amount of lab tests we do.

          Thanks again, I really appreciate it!


  • Is Oz Choc Banana (from the prior deal) the same as Coffs harbour choc banana?

    • I wanna know too, it's my fav flavour
