Epitalon: the longevity peptide
A synthetic peptide studied (largely in Russia) for longevity and effects on telomerase — with limited and early human evidence.

Follistatin: the myostatin brake
A protein studied for its ability to inhibit myostatin (a brake on muscle growth) — but human evidence for the injectable peptide forms marketed for muscle is limited.

Zinc Thymulin: the topical hair peptide
A zinc-bound thymic peptide studied topically for hair support — with limited human evidence.
