Tesamorelin- Summary
- Syn-Coll is a palmitoylated tripeptide (Palmitoyl Tripeptide-5) that mimics thrombospondin-1 to activate TGF-beta, the primary growth factor driving collagen synthesis in the dermis. It is one of the most mechanistically direct collagen-stimulating peptides in cosmetic formulations.
- 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.
