Tesamorelin- Summary
- Tripeptide-29 is a pro-collagen cosmetic peptide composed of proline, hydroxyproline, and glycine — the core repeating unit of collagen. Applied topically, it signals dermal fibroblasts that collagen degradation has occurred, triggering compensatory new collagen synthesis.
- Tesamorelin is an FDA-approved synthetic GHRH analog specifically indicated for reduction of excess abdominal (visceral) fat in HIV patients with lipodystrophy. It is the only GHRH peptide with FDA approval for a fat-reduction indication and is studied off-label for metabolic syndrome and cognitive function.
