What type of collagen do you use?

Both Frog Fuel and ProT GOLD derive their collagen from Grass-Fed Beef.  Our collagen is considered Type I and III.  Unlike other brands that procure and repackage bulk from overseas manufacturers, we produce our proprietary collagen in the USA to the highest standards of quality.

Our collagen formulation is a COMPLETE protein; containing ALL the essential, non-essential, and conditionally essential amino acids.

Every claim we make is backed by a proven study and through clinical use in numerous medical facilities around the world.
