Muscletech Prime Series Collagen Peptides, Multi-sourced Type I & Iii Hydrolyzed Collagen

Developed exclusively for Amazon, the Prime Series Collagen is a single ingredient, no compromise formula. Our Collagen comes from grass-fed, pasture-raised beef. We used the exact type I and III collagen used in clinical research. More so, it's convenience at its finest - it's flavorless, caffeine-free, gluten-free and dairy-free, so it mixes easily with whatever food or drink you're feeling.
