What is MUSCLE OTC?
A 4-in-1 solution built for every way life moves.
MUSCLE OTC was founded to make daily muscle nutrition simple and accessible. Built on over 16 years of research, our 4-in-1 formula combines 20 g protein, 5 g creatine, 800 IU vitamin D3 and 3 g LEUVATE® 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, healthy aging and clinician-guided weight management.
For adults using GLP-1 medication under medical care, a convenient protein and nutrient routine can complement adequate nutrition and resistance exercise. MUSCLE OTC is not a medication or substitute for medical care; consult your healthcare professional before use.
