What AOD-9604 is
A modified fragment of growth hormone developed for obesity that promotes fat metabolism in animals but failed to beat placebo in human weight-loss trials.
AOD-9604 is a synthetic analogue of the C-terminal fragment of growth hormone (residues 177-191) with an added N-terminal tyrosine. It was developed as an anti-obesity drug because it promotes fat breakdown without the growth-promoting or glucose effects of full growth hormone.
Mechanism: Stimulates lipolysis and inhibits lipogenesis in fat cells in animal models, without meaningful effects on IGF-1 or blood glucose.
Regulatory history: Not an approved drug (failed obesity trials); GRAS notifications as a food ingredient
How MHRA treats this kind of product
Licenses medicines for the UK market. A compound without a marketing authorisation is an unlicensed medicine, which can only lawfully be supplied for human use through a prescriber under the specials scheme, not sold as a research product.
The classification above is the The Longevity Archive reading of Medicines and Healthcare products Regulatory Agency listings for AOD-9604 at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
