What Is Chemyo RAD-140 (Testolone)? — Mechanism Explained
RAD-140, also known as Testolone, is a non-steroidal selective androgen receptor modulator (SARM) originally synthesised by Radius Health as an investigational alternative to testosterone therapy. Its defining characteristics — high binding affinity for the androgen receptor, strong tissue selectivity favouring muscle and bone over reproductive tissues, and oral bioavailability — have made it one of the most studied SARMs in both preclinical and early clinical settings.
Miller et al. (2011) first characterised RAD-140’s receptor binding profile and tissue-selective activity in preclinical models, demonstrating an anabolic-to-androgenic ratio exceeding 90:1. For context, testosterone has a 1:1 ratio. This exceptional selectivity is the core reason RAD-140 is the primary reference SARM for anabolic receptor research — it delivers the strongest muscle-tissue androgen receptor activation of any non-steroidal SARM while minimising androgenic signal in non-target tissues including the prostate, liver, and skin.
Upon binding, the RAD-140–androgen receptor complex translocates to the nucleus, interacts with androgen response elements (AREs) in DNA, and recruits tissue-specific transcriptional cofactors. The downstream MAPK/ERK signalling cascade has been observed in skeletal muscle cellular models. RAD-140 does not aromatise to estrogen and does not convert to dihydrotestosterone (DHT) — eliminating two key mechanisms responsible for androgenic side effects in traditional anabolic models.
Chemyo RAD-140 Testing — Triple-Blind Independent Verification
Chemyo uses the most rigorous active testing standard in the research SARM market. Every batch of RAD-140 at chemyo.io is verified through three independent tests, conducted blind — meaning the laboratory does not know whose product it is testing, eliminating any incentive to report favourable results:
Mass Spectrometry
Confirms the compound is RAD-140. Molecular fingerprint matched against certified reference standard.
Identity — blindHPLC Purity
Quantifies purity percentage. Minimum 99% required before batch is released for sale. Full chromatogram published.
≥99% requiredConcentration Assay
Finished solution tested against reference standard to confirm 10mg/ml matches the label exactly.
Potency verifiedPublic COA
All three results published. Searchable by your specific lot number before purchase.

Anabolic & Muscle Preservation
RAD-140 is the primary reference SARM for anabolic receptor research. Preclinical cynomolgus monkey models showed significant body weight increases after 28-day dosing. The >90:1 anabolic-to-androgenic ratio makes it the standard for lean mass and protein synthesis pathway studies.
Neuroprotection Research
Jayaraman et al. (2014) demonstrated RAD-140’s neuroprotective properties in cultured neurons and kainate-lesioned rat models, including protection from amyloid-beta–induced apoptosis. RAD-140 is among the most studied SARMs for Alzheimer’s disease receptor pathway research.
Oncology Receptor Models
RAD-140 was investigated by Radius Health for ER+/AR+ breast cancer models. Its selective receptor modulation in androgen receptor-positive tissue offers a research tool distinct from full agonist androgens in oncology receptor pathway studies.
Bone Density & Sarcopenia
Tissue-selective AR activation in bone makes RAD-140 relevant for osteoporosis and age-related bone loss research. The >90:1 selectivity ratio allows researchers to study bone anabolic signalling without the virilising confounders of testosterone-based models.
