Primaforce L-Leucine Powder – 5000mg, 60 Servings | Muscle & Recovery

Leucine is the branched-chain amino acid that actually flips the switch on muscle protein synthesis. The other two BCAAs support the process; leucine starts it. That is why it gets dosed on its own alongside training, and why it matters more as you get older and the muscle-building signal gets harder to trigger.

Why people take it

• Directly triggers muscle protein synthesis
• Useful around training and with lower-protein meals
• Popular with older adults working to hold on to muscle
