Gainz Stack – Men’s Bulk Bundle: Muscle Growth, Recovery & Peak Performance Support
The Gainz Stack from STAX Nutrition is engineered for men who want to build lean muscle, increase strength, improve recovery, and elevate overall athletic performance. This all-in-one bundle brings together three proven supplements—STAX BCAA, Spike Testosterone Booster, and Creatine Monohydrate—forming a powerful trifecta for bulking, strength cycles, and breaking through workout plateaus.
By combining targeted amino acids, natural testosterone support, and one of the most researched workout enhancers ever created, the Gainz Stack provides the essential building blocks your body needs to recover faster, grow stronger, and dominate every training session.
What’s Inside the Gainz Stack?
The bundle includes three foundational supplements that work synergistically to enhance performance:
-
STAX BCAA
-
Spike Testosterone Booster
-
Creatine Monohydrate
Each supplement plays a specific role in stimulating growth, fueling performance, and supporting hormone balance for optimal muscle-building results.
How the Gainz Stack Works
STAX BCAA – Recovery, Hydration & Anti-Catabolic Support
Branched-chain amino acids are essential for muscle repair and training endurance. They support:
-
Muscle protein synthesis
-
Reduced post-workout soreness
-
Prevention of muscle breakdown
-
Increased hydration and performance
Because they are rapidly absorbed and used during training, BCAAs keep muscles in an anabolic environment even during intense sessions.
Spike Testosterone Booster – Natural Hormone Optimization
Spike is formulated to support healthy testosterone function, a key factor in muscle growth, strength, and energy levels. Natural testosterone support helps promote:
-
Increased workout intensity
-
Better recovery
-
Improved body composition
-
Enhanced mood and vitality
Optimal hormone balance gives your body the internal environment needed for consistent progress.
Creatine Monohydrate – Strength, Power & Muscle Volume
Creatine monohydrate is one of the most scientifically validated performance enhancers available. It supports:
-
ATP production for explosive strength
-
Increased muscle volume through hydration
-
Greater power output
-
Lean muscle gains
Micronized creatine absorbs efficiently and requires no loading phase, making it simple and effective for daily use.
Key Benefits of the Gainz Stack

Natural Testosterone Support
Spike’s hormone-supporting ingredients help optimize strength, stamina, and energy, all of which impact muscle-building potential.
Enhanced Performance & Endurance
Creatine improves ATP output while BCAAs support endurance and hydration, giving you more power per rep and energy to sustain tough training sessions.
