IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified form of the naturally occurring insulin-like growth factor-1.

Follistatin-344 (FS344) is a naturally occurring protein produced throughout the body that acts primarily by binding to and neutralizing myostatin.

IGF-1 DES (1-3), also known as des-(1-3)-IGF-1, is a naturally occurring truncated form of insulin-like growth factor 1 (IGF-1) in.

The myostatin propeptide is a naturally occurring protein fragment that the body produces as part of myostatin, a powerful brake on muscle growth.
