The FDA review describes Tyr-hGH(177–191) and unsuccessful obesity evidence, including a large randomized study. The clinical findings should remain visible beside the mechanism.
Food-use GRAS context does not constitute injectable drug approval. Oral-study results cannot establish the effectiveness or safety of a different injected regimen.
Sources and proposed-mechanism explanation
The proposed rationale derives from a modified growth-hormone fragment. hCG and hGH are different hormones; a similar fragment label cannot settle molecular identity.
