Is OSKM Cyclic Partial Reprogramming legal in the United States?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
No. OSKM Cyclic Partial Reprogramming is not approved for any medical use in the United States. Its legal category is "Investigational, not approved". The only legal way to get it is to join a registered clinical trial (an official study in people). A "research use only" label on vials sold online does not make them legal to use in people. On the evidence, no study in people is cited on its profile.

What this means
- 01
OSKM Cyclic Partial Reprogramming is being tested in registered clinical trials (official studies in people). FDA has not approved it for sale in the United States.
- 02
The only legal ways for a person to get it are to join a trial, or to use an official early-access program where one exists. There is no pharmacy product to prescribe.
- 03
Vials sold online "for research use only" are not trial supplies. That label does not make them legal to use in people.
What OSKM Cyclic Partial Reprogramming is
All four Yamanaka genes, switched on in short bursts. It made a mouse bred to age too fast live longer, not a normal mouse. The same move in living mice causes tumours, including in the kidney.
Nobody has been given OSKM. There is no registered trial of four-gene reprogramming in people anywhere.
How it works: Shown in mice only. Short bursts of Oct4, Sox2, Klf4 and c-Myc push cells part way back toward being stem cells.
Approval history: Not approved anywhere. ClinicalTrials.gov lists no human study of OSKM reprogramming, which uses four genes. The only registered human reprogramming study uses the three-gene OSK set.
How FDA treats this kind of product
Approves prescription drugs, each for a named use. It also acts against unapproved products, including peptides sold online. Compounding pharmacies, which mix drugs to order, may make some compounds with a prescription. That only applies when the FDA puts the compound in a category of bulk ingredients it allows.
The legal category above is how The Longevity Archive reads U.S. Food and Drug Administration listings for OSKM Cyclic Partial Reprogramming on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.
OSKM Cyclic Partial Reprogramming in sport and the military
Whether OSKM Cyclic Partial Reprogramming is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in the United States. Before you compete or get tested, look up OSKM Cyclic Partial Reprogramming by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
