{"title":"RAD-140 (Testolone)","description":"\u003cp\u003eRAD-140 is a non-steroidal SARM, or selective androgen receptor modulator, first described by Radius Health in 2011. It is also sold as testolone or Radarine, has carried the development codes RAD140 and EP0062, and has the international nonproprietary name vosilasarm. It has high binding affinity for the androgen receptor and was designed to act preferentially in muscle and bone rather than in the prostate. This page lists every brand of RAD-140 stocked at Free Muscle, compared on strength per capsule, capsules per pack and batch testing, and summarises what the published research does and does not show.\u003c\/p\u003e\n\u003ch2\u003eWhat is RAD-140?\u003c\/h2\u003e\n\u003cp\u003eRAD-140 belongs to the SARM class: synthetic, non-steroidal ligands of the androgen receptor (AR), the same nuclear receptor that testosterone and dihydrotestosterone act on. The premise of the class is tissue selectivity: strong receptor activation in skeletal muscle and bone, much weaker agonism in the prostate, seminal vesicles and skin. RAD-140 was reported by its discoverers to be a potent, orally bioavailable AR ligand that showed this pattern in animal models.\u003c\/p\u003e\n\u003cp\u003eRadius Health originally explored RAD-140 as a treatment for muscle wasting and, later, as an oral AR-targeted agent for androgen receptor positive breast cancer. The only published clinical trial came from that oncology programme, a small first-in-human phase 1 study in postmenopausal women with metastatic breast cancer; beyond it, the only studies in people are doping-control experiments in which men received micro-doses so that their urine could be analysed. There are no published controlled trials of RAD-140 in healthy adults, and no data at all on the long-term effects of the compound in people.\u003c\/p\u003e\n\u003cp\u003eNo regulator anywhere has approved RAD-140 as a medicine, and it holds no marketing authorisation from the MHRA, EMA or FDA. Its clinical development has not ended, however. Under the code EP0062 it is an investigational cancer drug in a phase 1\/2 study, sponsored by Ellipses Pharma, in advanced breast cancer that is androgen receptor positive, oestrogen receptor positive and HER2-negative; the registry record, last updated in June 2026, lists the study as recruiting at sites in the UK, the US and Spain (NCT05573126).\u003c\/p\u003e\n\u003cp\u003eIdentity, as recorded in PubChem:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCAS number\u003c\/strong\u003e: 1182367-47-0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular formula\u003c\/strong\u003e: C20H16ClN5O2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular weight\u003c\/strong\u003e: 393.8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePubChem CID\u003c\/strong\u003e: 44200882\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternational nonproprietary name\u003c\/strong\u003e: vosilasarm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat the published research reports\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDiscovery and preclinical characterisation (2011).\u003c\/strong\u003e Miller and colleagues at Radius Health described the design and synthesis of RAD140 and its characterisation in several preclinical models of anabolic androgen action, reporting it as a potent, orally bioavailable, non-steroidal SARM.

In culture, RAD140 was as effective as testosterone at reducing apoptotic cell death, an effect that depended on MAPK signalling. In gonadectomised adult rats it exhibited peripheral androgen action that largely spared the prostate while protecting hippocampal neurons.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFirst-in-human phase 1 study (2022).\u003c\/strong\u003e LoRusso and colleagues enrolled 22 heavily pretreated postmenopausal women with ER-positive, HER2-negative metastatic breast cancer in a dose-escalation study. The most frequent treatment-emergent adverse events were elevated AST (59.1 per cent of patients), elevated ALT (45.5 per cent), raised total bilirubin (27.3 per cent), vomiting, dehydration and decreased appetite and weight. Grade 3 or 4 adverse events occurred in 72.7 per cent of patients, including AST and ALT elevations and hypophosphataemia. Clinical benefit rate at 24 weeks was 18.2 per cent and median progression-free survival was 2.3 months. The elimination half-life came out at 44.7 hours.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMicro-dose excretion studies in men (2022).\u003c\/strong\u003e At the German Sport University Cologne, Wagener and colleagues ran six micro-dose excretion studies with five adult male volunteers in each, to map how RAD-140 is metabolised and eliminated. They described several urinary metabolites seen in humans for the first time and reported detection times for six metabolites and for the unchanged drug. The work was designed to support doping control, not to measure any effect.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLiver injury case reports (2020 to 2026).\u003c\/strong\u003e Outside any trial, at least six published case reports describe liver injury after use of products sold as containing RAD-140, most with a cholestatic pattern, in which the flow of bile from the liver is impaired. Case reports cannot show how often this happens, and some involved more than one compound.

Where it shows a dash, the manufacturer does not state the strength per capsule, so total milligrams and price per milligram cannot be worked out from the label. Price per milligram also compares like with like only when each pack has an independent certificate for its lot number.

Identity: the mass spectrum should fit the formula C20H16ClN5O2; worked out from that formula, the protonated molecule seen in positive-ion mode falls near m\/z 394, with a smaller chlorine isotope signal two units higher. Purity: how much of the total chromatographic peak area is RAD-140. Content: the milligrams found per capsule, set against the strength on the label. An ordinary non-chiral method cannot tell the (1R,2S) form apart from its mirror image, so a high purity figure cannot show which of the two is present.\u003c\/p\u003e\n\u003cp\u003eThe content line matters most in this market. When LGC scientists analysed SARM products sold to UK consumers, one held no active ingredient at all, some held prohibited substances missing from the label, and in products that did contain a SARM, the quantity found did not always agree with the quantity declared (Leaney 2021). Each Free Muscle batch of RAD-140 is sent for assay to Janoshik Analytical, an independent laboratory, and we email you the certificate for your batch when you send us the batch number on the bottle. On the iMuscle, Yakka Strength and Thoroughbred Labs listings a certificate appears only if that manufacturer has provided one for the batch in our stock.

UK Anti-Doping has also reported a 2025 case in which an out-of-competition urine sample from a British lacrosse player returned adverse findings for RAD140 and ostarine; he accepted a five-year ban that runs to May 2030, and his suggestion that a supplement was contaminated could not be supported because the supplement was not available for analysis.

Like other SARMs it binds the androgen receptor, but it has no steroid ring system and its structure is unrelated to testosterone. Radius Health described its discovery in 2011 as a potent, orally bioavailable SARM and reported its characterisation in several preclinical animal models of anabolic androgen action (Miller et al., 2011).\u003c\/p\u003e\u003cp\u003eRAD-140 later entered a Phase 1 oncology trial in women with ER-positive, HER2-negative advanced breast cancer, published in 2022 (LoRusso et al., 2022). Twenty-two heavily pretreated patients took part. The adverse events recorded most often were raised AST (59%), ALT (45%) and bilirubin (27%), and grade 3 or 4 events occurred in 16 of the 22. Outside clinical research, published case reports link RAD-140 to cholestatic liver injury, including a biopsy-supported case in a 24-year-old man that resolved after exposure stopped (Leung et al., 2022).\u003c\/p\u003e\u003cp\u003eThe only other structured human data come from anti-doping research: a 2022 Cologne study gave adult male volunteers microgram amounts to chart how RAD-140 is excreted, covered under detection below (Wagener et al., 2022).

On them the ester bound the receptor about 65 times more weakly than RAD-140. A living system may split an ester back to its parent, so this does not settle what RAD-150 does there, but it argues against the ester being a stronger ligand in its own right. Claims that it lasts longer or acts more strongly are unmeasured, and whether, and how fast, it becomes RAD-140 in the body is unknown.\u003c\/p\u003e\u003cp\u003eThe heavier formula matters for labels too: roughly a fifth of the ester's mass comes from the added benzoate portion, so a milligram figure for RAD-150 and the 600 mg on this pack do not describe the same quantity of the RAD-140 structure. Legally the two are alike: neither is a licensed medicine or an authorised food, and both are sold here for laboratory research only.

At the German Sport University Cologne, six excretion studies, each with five adult male volunteers, used single or five daily amounts of 1, 10 or 50 micrograms, and their urine was analysed by LC-HRMS\/MS (Wagener et al., 2022). Unchanged RAD-140 outlasted all six metabolites tracked in every group. After one 50 microgram amount it was found up to 696 hours later, about 29 days; after five daily amounts of 50 micrograms, up to 912 hours, about 38 days, after the last. Part of the aim was to help laboratories judge whether a finding reflects deliberate use or contamination.\u003c\/p\u003e\u003cp\u003eEvery figure above comes from microgram exposures. How long RAD-140 remains detectable after milligram quantities, such as the 10 mg stated per capsule here, has not been reported that we know of, so for this product: detectable, window not established.

The molecule was first described in a 2011 paper from Radius Health, which described it as a potent, orally bioavailable, non-steroidal SARM and reported its characterisation in several preclinical models of anabolic androgen action (Miller et al., 2011). Those models were animal experiments, not human studies.\u003c\/p\u003e\u003cp\u003ePubChem records it under CAS number 1182367-47-0, formula C20H16ClN5O2, molecular weight 393.8 and InChIKey XMBUPPIEVAFYHO-KPZWWZAWSA-N. The systematic name, 2-chloro-4-[[(1R,2S)-1-[5-(4-cyanophenyl)-1,3,4-oxadiazol-2-yl]-2-hydroxypropyl]amino]-3-methylbenzonitrile, shows two defined stereocentres and no steroid ring system, and vosilasarm is listed among its synonyms.\u003c\/p\u003e\u003cp\u003eThe only published human trial is a Phase 1 dose-finding study in patients with hormone-receptor-positive metastatic breast cancer, reported in 2022 (LoRusso et al., 2022). Raised AST, ALT and bilirubin were among the most frequent adverse events, grade 3 or 4 adverse events occurred in 16 of the 22 patients, and the investigators identified a maximum tolerated dose. Two blood markers moved as expected for an androgen: sex hormone-binding globulin fell in every one of the 18 women tested and prostate-specific antigen rose in 16 of 20, which the investigators took as evidence that the receptor was engaged. The trial assessed tolerability and tumour response, not muscle or strength. Outside trials, case reports describe cholestatic liver injury in people who had taken products sold as RAD-140 (Leung et al., 2022), and hypogonadism in a man whose supplements contained RAD-140 together with other undeclared substances, so no single compound could be blamed (Chong et al., 2024).

The legal answer is narrow. RAD-140 has no MHRA marketing authorisation, so it is not a licensed medicine in the UK; it is not an authorised food supplement; and it therefore cannot lawfully be sold for human consumption. Free Muscle sells it to adults aged 18 or over for laboratory research only. WADA prohibits it at all times under section S1 (anabolic agents), and buyers are responsible for the rules that apply to them, including any anti-doping code.

The same study measured an elimination half-life of 44.7 hours.

Anti-doping rules apply strict liability: an athlete is responsible for any prohibited substance found in their sample, whatever its source.\u003c\/p\u003e\u003cp\u003eThe most detailed human elimination data come from a 2022 study at the German Sport University Cologne. In six controlled excretion studies, each with five adult male volunteers given very small amounts of RAD-140, urine was analysed by LC-HRMS\/MS. Concentrations peaked two to six hours after administration and then fell slowly. Unchanged RAD-140 remained detectable for up to 29 days after a single administration of the largest amount studied, and it accumulated when administration was repeated on consecutive days. The parent compound was detectable for longest, and several metabolites were described in human urine for the first time. The authors framed the work partly around contaminated supplements, which can also cause positive findings.\u003c\/p\u003e\u003cp\u003eNo published study gives a detection window for the quantities in commercial capsules, so for this product the accurate statement is: detectable, window not established.

Moisture is the main risk to capsules: capsule shells, gelatine ones in particular, soften and stick together in humid air and turn brittle when very dry, and damp powder degrades faster than dry. Heat speeds up both. Do not decant capsules into unlabelled containers: the batch number on the original pack is what ties the contents to a certificate.\u003c\/p\u003e\u003cp\u003eWe are not aware of published stability data for RAD-140 in capsule form, so the expiry or best-before date on the pack, where printed, is the limit to work within.

Ordinary laboratory good practice applies: wear gloves when handling opened capsules or powder, work away from food and drink, keep the pack out of reach of children and animals, label any sample taken from the pack with compound, batch and date, and dispose of unwanted material as chemical waste, not via household bins or drains.\u003c\/p\u003e\u003ch2\u003eGlossary\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSARM\u003c\/strong\u003e: selective androgen receptor modulator, a non-steroidal androgen receptor ligand designed to act more on muscle and bone than on the prostate.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAndrogen receptor\u003c\/strong\u003e: the nuclear receptor activated by testosterone and dihydrotestosterone.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTestolone and vosilasarm\u003c\/strong\u003e: other names for RAD-140; testolone is an informal market name, vosilasarm the non-proprietary name used in reference databases such as PubChem.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEster\u003c\/strong\u003e: a compound formed by joining an acid to an alcohol group; RAD-150 is the benzoic acid ester of RAD-140.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHalf-life\u003c\/strong\u003e: the time taken for the concentration of a compound in the blood to fall by half.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase 1 trial\u003c\/strong\u003e: the first stage of human testing, focused on tolerability and pharmacokinetics in a small group.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHPLC\u003c\/strong\u003e: high-performance liquid chromatography, which separates a sample into its components; the usual basis of a purity figure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLC-MS\u003c\/strong\u003e: liquid chromatography with mass spectrometry, which also measures molecular mass and so gives firmer proof of identity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertificate of analysis (COA)\u003c\/strong\u003e: a laboratory report on one specific batch, carrying its batch number and test date.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWADA S1.2\u003c\/strong\u003e: the Prohibited List section for other anabolic agents, including SARMs, banned at all times.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMHRA\u003c\/strong\u003e: the Medicines and Healthcare products Regulatory Agency.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eAbout Yakka Strength RAD-140\u003c\/h2\u003e\n\u003cp\u003eYakka Strength sells this pot as \"RAD140 Testolone\": that is the front label, in red lettering on the brand's standard black design, above \"60 capsules\" and the research-purposes-only line; the side panel carries a short facts table, RAD140 10 mg per capsule and 60 capsules per container, which makes 600 mg per pot as labelled, plus \"Made in the UK\", and the back panel gives Yakka Strength Ltd as distributor.
