Is Retatrutide legal?
Not as a drug. Retatrutide has no FDA approval, so selling it for human use breaks federal drug law, and a 'research use only' label does not protect a seller whose site signals human use. It is not a controlled substance, and possessing it is not a federal crime. Pharmacies cannot compound it.

State rules
2 STATESOhio's Board of Pharmacy names retatrutide among the research-use-only GLP-1s its inspectors find in clinics and says possessing any drug labelled 'for research purposes only' is unlawful for prescriber clinics and med spas. It summarily suspended several out-of-state pharmacies over investigational GLP-1s in May 2025.

California's Sherman Law (Health and Safety Code §111550) bars selling or giving away a new drug without FDA or state approval. Retatrutide has neither, so a sale for human use in California breaks state law as well as federal law. No California rule names retatrutide itself.

In the other states we found nothing that names Retatrutide; federal law applies.

Questions
3 ANSWERSIs Retatrutide legal in the US?
Not as a drug. Retatrutide has no FDA approval, so selling it for human use breaks federal drug law, and a 'research use only' label does not protect a seller whose site signals human use. It is not a controlled substance, and possessing it is not a federal crime. Pharmacies cannot compound it.
Can a pharmacy compound Retatrutide?
Not eligible. Retatrutide has no FDA approval, no USP monograph and is not on the 503A Bulks List; FDA warning letters state it cannot be lawfully compounded. Ohio's Board of Pharmacy names it as a research-use-only drug its inspectors find in clinics.
Is Retatrutide banned in sport?
Yes. It is prohibited at all times under WADA 2026 class S0. Not named, and GLP-1 agonists as a class are not on the 2026 List. Retatrutide falls under S0 because no government has approved it. WADA's 2027 List, in force from 1 Jan 2027, now names 'peptides' among the S0 examples; the status does not change.
