Arimistane is a non-peptide C19 steroidal compound (androstane-based) marketed as a mechanism-based aromatase inhibitor and sold as a gray-market bodybuilding supplement ingredient. It is a 7-keto-DHEA metabolite/degradation product with no approved therapeutic use. The FDA determined in 2021 that arimistane does not meet the definition of a dietary ingredient and fails GRAS criteria for food use. It is prohibited under the WADA Prohibited List (Section S4, Aromatase Inhibitors) and was added to the list in 2017.

How are Arimistane prices verified on Disclosed Labs?
Every listed vendor holds a Grade C or better trust score, computed independently from lab Certificates of Analysis — not from payments or sponsorships. Prices are scraped and fact-checked daily. Vendors cannot pay to improve their ranking.
Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Use the Full safety panel filter to require endotoxin, sterility, and heavy-metals testing on the current batch — not just HPLC purity.
No registered efficacy or safety clinical trials exist for arimistane. The only human data are two small anti-doping analytical studies: (1) a single 25 mg oral dose in 3 healthy volunteers produced up to 15 novel urinary metabolites, with parent compound detected in the sulfate fraction and no relevant acute effects on the steroid profile; (2) a separate single-dose study (3 volunteers, up to 10 hours) identified 12 additional reduced/hydroxylated urinary metabolites and detected unchanged parent in urine. In vitro (human placental microsomes): the close analog androst-5-ene-7,17-dione is a time-dependent, NADPH-dependent suicide substrate of aromatase; a series of related androsta-3,5-dien-7-ones/androst-5-en-7-ones competitively inhibited aromatase (Ki 0.058–45 µM), with 17-oxo derivatives more potent than 17-beta-hydroxy derivatives. Arimistane itself was not unambiguously confirmed among the specific tested compounds in the latter study.
