Animal M-Stak Review by Bryan60275

Disappointed. I even added Z-force (ZMA + additional 20-hydroxyecdysone + additional tribulus) and I didn't see any improvements on a roughly 4000 calorie diet... I expected more to be honest. At the most, I thought I leaned out a touch but maintained a constant weight of 172-173 for the duration of the 21 days. Normal strength increases, no weight change.

I wouldnt bother if I were you. It's not worth it.
