Premium WPI
A clean, high-quality protein foundation.

Our purpose
MUSCLE OTC was founded to make daily muscle nutrition simple and accessible. Built on over 16 years of research and powered by LEUVATE®, our all-in-one formula combines high-quality protein, creatine and vitamin D3 to support muscle protein synthesis, strength, recovery and long-term muscle health.
Our mission is to move muscle nutrition beyond bodybuilding—supporting healthy adults through active living, rehabilitation routines, performance and healthy aging.
Muscle supports how we stand, walk, lift, recover and stay independent. MUSCLE OTC turns those needs into one simple daily routine with evidence-informed ingredients in meaningful amounts.
