RAD-140 is one of the most-researched SARMs, commonly discussed in studies on lean mass and androgen receptor selectivity. Below, we compare vendors currently stocking research-grade RAD-140 — not just a single sales page.
Prices and testing claims are pulled from each vendor's product listing. Always confirm current price and COA (Certificate of Analysis) on the vendor's site before buying.

RAD-140 (Testolone) is a nonsteroidal selective androgen receptor modulator (SARM) originally developed by Radius Health, studied for its tissue-selective anabolic activity as an alternative to traditional anabolic steroids in muscle-wasting and oncology research.
Research-grade RAD-140 is typically supplied as capsules or a lyophilized powder, commonly at 10mg per capsule in 60-count bottles, intended for laboratory research use only.
RAD-140 binds the androgen receptor with high affinity and is studied for producing anabolic effects in muscle and bone tissue while exhibiting reduced activity in reproductive tissue compared to testosterone — the defining research premise of SARMs as a drug class.
RAD-140 has been investigated in preclinical models for its effects on lean muscle tissue and strength, and it remains one of the most-studied SARMs in that specific research context.
Because RAD-140 was also studied in the context of androgen-receptor-positive breast cancer, it has a body of published research examining its receptor-selective activity in oncologic models distinct from its bodybuilding-community popularity.
RAD-140 has not received FDA approval for any indication, and available human data comes from early-phase and preclinical research rather than large-scale trials. SARMs as a class have been associated in case reports with liver enzyme elevation and suppression of natural testosterone production; RAD-140 is also on the World Anti-Doping Agency's list of prohibited substances.
Doses studied in available preclinical and early-phase research vary by study design and are not established as a standardized human protocol. No FDA-approved human dosage exists for RAD-140.
Compound X does not sell RAD-140 directly. We provide independent research, comparisons and vendor links — see the vendor comparison table above for current US, UK, Canada and Australia options.
RAD-140 research is indexed on PubMed under search terms such as "RAD140 Testolone SARM" and "selective androgen receptor modulator RAD-140."
