Animal M-Stak is Universal Animal's non-hormonal pack for hardgainers — athletes who struggle to add muscle even when training and eating are in order. Each daily pack combines plant sterones (including turkesterone and beta-ecdysterone), a 3,000 mg anti-catabolic amino complex, an insulin-potentiating complex, adaptogens, and an energy complex that contains caffeine, kola nut and guarana in a single red capsule. 21 packs per container — one three-week cycle.

Animal's current packaging is a reformulated version of M-Stak (it adds PEAK ATP® and a Peak O2® mushroom blend and keeps the same 500 mg Energy Complex). Lots differ — always follow the panel on your container.
Key Benefits
- Non-hormonal by design — Animal builds M-Stak around plant sterones (turkesterone, beta-ecdysterone) and phytosterols rather than hormone-support botanicals
- 3 g anti-catabolic amino complex — leucine, isoleucine, valine, taurine and acetyl-L-carnitine in every pack
- Nutrient-partitioning support — fenugreek, banaba, cinnamon and R-ALA make up the insulin potentiating complex
- Adaptogens included — ashwagandha, kudzu and eleuthero
- Energy complex you control — the caffeine, kola nut and guarana sit in one red capsule that Animal says you can leave out
Best For
- Hardgainers who struggle to add lean mass despite consistent training and nutrition
- Natural athletes who want a multi-complex pack without hormone-support ingredients
- Those who like a pack format: one sealed strip of pills a day for a 21-day block
Not Ideal For
- Caffeine-sensitive people, or anyone already using a caffeinated pre-workout or fat burner — M-Stak contains caffeine (remove the red capsule, or choose another product)
- Late-evening trainers who keep the red capsule in
- Those under 18, or anyone pregnant or nursing
- Those who prefer a single-ingredient supplement approach
