Saw this MuscleTech Shatter Pre-Workout Tropical Paradise 387g at Woolies today.
Per scoop:
200mg Caffeine
1.2g Beta-Alanine
400mg L-Tyrosine
BCAA Matrix




Beta-Alanine makes my face/arms tingle, totally hate it and cant work out as feels like dead arm or something.
It is totally harmless side effect but some people get it. Hard to find Beta-Alanine free ones, I just use energy drinks mostly.
