Follistatin-344
Muscle growth
A peptide that blocks myostatin signaling—discussed for muscle mass but with serious safety unknowns.
Follistatin inhibits myostatin, a protein that limits muscle growth. Gene-therapy and peptide approaches have shown dramatic muscle gains in animals. Human use is experimental; long-term safety is not established.…
IGF-1 LR3
Muscle growth
A modified insulin-like growth factor with a longer half-life—highly potent and tightly regulated.
IGF-1 LR3 binds IGF receptors to promote muscle cell hyperplasia. It is significantly more potent than endogenous IGF-1 and carries hypoglycemia risk. Banned in sport; not a casual recovery peptide.…

Are Follistatin-344 and IGF-1 LR3 the same peptide?
No. They are different molecules with distinct names on labels and in research databases. Always match the full INCI or drug name—not a nickname on the front of the package.
Which is better for performance—Follistatin-344 or IGF-1 LR3?
Neither page is medical or anti-doping advice. Research peptides discussed in fitness communities may be prohibited in tested sport or unavailable as OTC supplements. Verify WADA lists and talk to a clinician.
