Tesamorelin- Summary
- AHK-Cu is a copper tripeptide composed of alanine, histidine, and lysine chelated to copper. Distinct from GHK-Cu, AHK-Cu exhibits strong affinity for hair follicle receptors and demonstrates potent hair growth stimulation alongside wound healing and skin regeneration properties.
- 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.
