Wholesale RAD-140 (Testolone)
Bulk powder, capsules and white label — B2B supply from our UK and EU facilities. Manufactured to GMP standard at ≥98% purity, verified by HPLC and LC-MS, with a Certificate of Analysis on every batch. Supplied strictly B2B for research purposes only.
Overview
One of the most selective SARMs in the class
RAD-140, also known as Testolone, is a non-steroidal selective androgen receptor modulator developed by Radius Health, Inc. — the source of the "RAD" designation. It is characterised in the literature by high binding affinity and marked selectivity for androgen receptors in muscle and bone tissue over other tissues, which is what drew it into clinical evaluation and has since made it one of the most in-demand compounds in B2B research supply.
SARMs-Direct supplies wholesale RAD-140 in raw powder and encapsulated formats to supplement brands, sports nutrition retailers, research institutions, white label operators and distributors across Europe and internationally. All supply is strictly B2B and sold for research purposes only.

Research context
Development & study background
RAD-140 was developed by Radius Health as a non-steroidal androgen receptor agonist with tissue-selective activity. Preclinical work characterised it as having a high anabolic-to-androgenic ratio relative to testosterone, meaning pronounced activity at receptors in muscle and bone with comparatively limited activity elsewhere — the defining design goal of the SARM class.
It subsequently entered Phase I clinical evaluation in patients with androgen receptor-positive breast cancer, where the rationale was its selective receptor activity rather than any performance application. Separate preclinical research has examined potential neuroprotective properties in models of neurodegeneration.
Compared with Ostarine (MK-2866), RAD-140 is generally described as having greater potency at lower concentrations, while Ostarine carries the more extensive clinical trial record. Ligandrol (LGD-4033) sits between the two on both measures.
