Regulatory record

Regulatory recordSupporting passage inspected

FDA states that SARMs are not FDA approved. Its class warning describes reports of serious adverse effects associated with marketed SARM products, including liver injury. This does not establish the frequency or cause of an event for each individual compound.[1]

Jurisdiction
United States
Product
Products marketed as selective androgen receptor modulators
Indication
No FDA-approved SARM therapeutic indication in the cited agency communication
Record date

  • Class-level regulatory advice must not be mistaken for a study of every individual SARM or combination.
Inspection history

Clinical review: not reviewed by a qualified clinician.

· Independently inspected the listed passages; replaced or qualified inherited assertions. No qualified clinical review has occurred.

· Independently reopened the FDA page directly; the live URL returned an automated bot-detection response on this attempt, so the Internet Archive Wayback Machine snapshot dated 2026-05-18 was read as a lawful alternative. Confirmed the full page text verbatim, that it names no individual SARM, and its footer statement Content current as of 04/26/2023. This claim's own regulatory.asOf field still carried the evidence-cutoff placeholder (2026-09-08) rather than the source's actual date even though the source record itself was already corrected to 2023-04-26 by an earlier batch; corrected regulatory.asOf to 2023-04-26 here. The claim text required no change. Independent editorial review pending.

· Independent editorial review: the 2026-09-09 change of regulatory.asOf from 2026-09-08 to 2023-04-26 is rejected and reverted. Every other regulatory claim in the published model (17 of 18, by direct count) and two prior coordinator corrections in this same pass (aas-coordinator-edits.json, ancillary-coordinator-edits.json) establish that regulatory.asOf records the date through which this pass confirms the described status is still current, capped at the evidence cutoff -- not the cited document's own date, which is already fully recorded on the source record's own publicationDate and availableBy fields. regulatory.asOf is restored to 2026-09-08. No other change to this claim's text, sources or limitations was required; independently reconfirmed the FDA page's class-only, no-molecule-named framing, its exact adverse-event list including liver injury and acute liver failure, and its footer date. No qualified clinical review has occurred.

Pharmacokinetics

Animal / laboratoryAbstract inspected

LGD-3303 pharmacokinetics and tissue effects were characterized in rat experiments. A half-life from that work should be labeled as animal data and should not be presented as a measured human value.[2]

  • This review does not establish human absorption, endocrine suppression or recovery.
  • LGD-3303 is a chemically distinct nonsteroidal SARM from LGD-4033 (ligandrol); this source did not study LGD-4033 and reports no numeric half-life value in its own abstract.
Inspection history

Clinical review: not reviewed by a qualified clinician.

· Independently inspected the listed passages; replaced or qualified inherited assertions. No qualified clinical review has occurred.

· Reopened the abstract via Europe PMC REST; confirmed it describes only a castrated-rat pharmacokinetic and pharmacodynamic experiment (oral and continuous-infusion dosing; levator ani muscle, preputial gland and ventral prostate tissue concentrations) and states no numeric half-life value itself. Attempted the JPET/ASPET publisher full text at both its legacy and current URLs; both returned an HTTP 403 JavaScript and cookie interstitial. Europe PMC confirms no PMC copy exists for this record, so no open-access full text is available; inspection stays abstract-level. No indexed correction or retraction found. A PubMed search for LGD-3303 human surfaced no human LGD-3303 study, only an unrelated 2023 equine doping-control metabolite paper and a 2010 general SARM review; neither changes this claim. Independent editorial review pending.

What remains unresolved

Editorial assessment

These notes describe the scope of this review. Linked PMIDs are audit identifiers; an identifier alone does not verify a claim.

Explicitly identified the rat model and withheld a human half-life.

  • Human efficacy, clinical safety, quantitative suppression and recovery remain unverified.
  • Other inherited assertions not supported by the published claim set remain unverified; no qualified clinician review has occurred.

This reference does not supply a dosing plan, monitoring timetable or recovery regimen. Discuss personal symptoms, medicines and laboratory results with a qualified clinician.
