Building muscle mass requires three things: a caloric surplus, sufficient protein (1.6–2.2 g/kg body weight daily), and progressive overload in the gym. Here we have gathered the supplements with the strongest scientific support for hypertrophy — whey protein, creatine monohydrate, mass gainers, and BCAA.## Why These Supplements Work
Muscle growth (hypertrophy) occurs when muscle protein synthesis (MPS) exceeds its breakdown. Three factors are critical:
1. **Amino acid saturation** — especially leucine (≥2.5 g per meal activates the mTOR pathway)
2. **Energy surplus** — at least +250 kcal above maintenance
3. **Creatine saturation** — increases ATP in muscles by 15%
## Recommended Daily Protocol for +5 kg in 6 Months
- **Morning**: 30 g whey protein + 5 g creatine
- **Pre-workout**: 5–8 g BCAA or EAA
- **Post-workout**: 30 g whey isolate + fast-acting carbohydrate
- **Before bed**: 30 g casein (slow protein)
For hardgainers, add 1–2 full servings of mass gainer (700–1000 kcal/serving) to easily meet calorie needs.
## What to Expect
With a proper diet, training 4–5 times/week, and the supplements above, the average increase is **0.5–1 kg of lean muscle mass/month** for beginners, and 0.25–0.5 kg for advanced individuals.
