Animal Stak 21 Packs
For hardgainers, the struggle isn’t effort — it’s biology. Testosterone levels, protein synthesis efficiency, and how well your body holds on to muscle under training stress all determine whether hard work translates into real gains. Animal Stak from Universal Nutrition is engineered specifically to address those biological levers, naturally boosting free testosterone while simultaneously enhancing the anabolic environment your muscles need to grow and recover.
Unlike single-ingredient test boosters, Stak takes a multi-pathway approach: raising free testosterone naturally, enhancing protein synthesis and nitrogen retention to keep your body in an anabolic state, and providing anti-catabolic support to protect hard-earned muscle from breakdown during intense training cycles. The result is a comprehensive stack that turns a hardgainer’s physiology in their favour.
- Naturally boosts free testosterone
- Enhances protein synthesis & nitrogen retention
- Anti-catabolic support to protect muscle mass
- Improved nutrient partitioning for lean gains
- 21 convenient daily packs — one full 3-week cycle
Directions:
Take 1 pack daily for 21 consecutive days. On training days, take 30–45 minutes before lifting. On rest days, take before bed. Cycle 3 weeks on, 1 week off for best results.
