Tesamorelin: the approved GHRH analog most researchers overlook

A full FDA approval, phase 3 visceral-fat data, and lessons for evaluating its gray-market cousins.

Tesamorelin is the rare GH-axis peptide with a complete regulatory dossier: GMP manufacturing, phase 3 trials, and an FDA approval for HIV-associated lipodystrophy. That makes it a useful benchmark for what proven GHRH-analog pharmacology looks like.

The comparison illuminates its unapproved cousins: CJC-1295 shares the mechanism class but not the evidence, and the gap between the two is a case study in why approval status belongs in every compound evaluation.
