What this means

  • 01

    MHRA has approved Nandrolone decanoate for at least one labeled indication, so a pharmaceutical-grade product exists in the United Kingdom and is dispensed on prescription.

  • 02

    Approval is indication-specific. Uses outside the label are a clinical decision for a prescriber, not something the approval itself authorizes.

  • 03

    Unlicensed online vials, including those labeled "research use only", are not the approved product and are not covered by the approval.

What Nandrolone decanoate is

Randomised trials in dialysis, in burns, and a 2025 meta-analysis in postmenopausal osteoporosis. The medical record is real and the drug was withdrawn in most markets anyway.

Nandrolone has the broadest medical trial record of any anabolic steroid besides testosterone itself, across three separate populations that share one feature: the body is losing tissue it cannot replace. In dialysis patients, a randomised trial in JAMA found anabolic effects.

Mechanism: 19-nortestosterone, testosterone lacking the 19-carbon methyl group, esterified with decanoic acid for a long-acting oil depot. It binds the androgen receptor with high affinity and is a poor substrate for aromatase, so it produces relatively little oestradiol.

Regulatory history: Previously FDA-approved for anaemia of renal insufficiency. Withdrawn from the United States market. Schedule III controlled substance. Still licensed in some other countries.

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 Nandrolone decanoate 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.
