Overview
RAD-140, also called testolone, is a non-steroidal selective androgen receptor modulator — a SARM. It is not a peptide and not a steroid: it is a small organic molecule of 393.83 g/mol, CAS 1182367-47-0, discovered in a medicinal-chemistry programme at Radius Health and first described in the scientific literature around 2011. Its scaffold bears no resemblance to the steroid nucleus, which is precisely the design point.
No SARM, RAD-140 included, is an approved medicine anywhere, and none may lawfully be sold as a dietary supplement in the United States. We supply it as capsules or as a research liquid, HPLC tested with a lot-matched Certificate of Analysis available, strictly for laboratory research use.

Questions about RAD-140 (Testolone)
What is RAD-140?
RAD-140, or testolone, is a non-steroidal selective androgen receptor modulator with a molecular weight of 393.83 g/mol. It binds the androgen receptor without a steroid scaffold and is used in laboratory research on receptor transactivation, tissue-selective anabolic models and AR-positive tumour models.
Is RAD-140 a steroid or a peptide?
Neither. It is a small non-steroidal organic molecule. It shares the androgen receptor as a target with anabolic steroids but has an entirely different structure, and unlike testosterone it is not a substrate for aromatase or 5-alpha-reductase.
Which format should a laboratory choose?
Capsules at 10 mg × 60 suit work where a fixed, pre-measured unit is convenient. The 30 mL research liquid at 20 mg/mL suits volumetric handling and dilution series. Both are drawn from HPLC-tested material with a lot-matched Certificate of Analysis.
How is purity verified?
Each lot is tested by HPLC for purity of at least 98% with identity confirmation, and the lot-matched Certificate of Analysis is available on this page before purchase. Independent analyses have found frequent mislabelling across the SARM market, which is why lot documentation matters.
Is RAD-140 approved or legal as a supplement?
No. It has no marketing approval in any jurisdiction, and in the United States SARMs do not meet the definition of a dietary ingredient, so they cannot lawfully be sold as dietary supplements. It is listed here strictly as a research chemical.
Is it banned in sport?
Yes. SARMs including RAD-140 are prohibited at all times under the World Anti-Doping Agency anabolic agents category, and validated detection methods exist. Nothing on this page should be read as encouragement to use the compound in sport.
