## Description

RAD-140 — also known as testolone — belongs to the non-steroidal selective androgen receptor modulators, or SARMs. It is neither a peptide nor a steroid but a small organic compound (393.83 g/mol, CAS 1182367-47-0) that came out of a Radius Health medicinal-chemistry programme and first appeared in published research around 2011. Its framework looks nothing like the steroid nucleus — which was exactly the design goal.

No SARM — RAD-140 among them — has been authorised as a medicine in any country, and none may legally be sold as a food supplement in the EU or as a dietary supplement in the US. We offer it in capsule form or as a research liquid, tested by HPLC and documented with a Certificate of Analysis for each lot, strictly for use in laboratory research.

## Frequently asked questions

### What is RAD-140?

RAD-140 (testolone) is a SARM — a non-steroidal compound that acts selectively on the androgen receptor — weighing 393.83 g/mol. It attaches to that receptor without having a steroid structure, and labs use it to study how the receptor switches on genes, in models of tissue-selective muscle and bone building, and in tumour models that carry the androgen receptor.

### Is RAD-140 a steroid, or a peptide?

It is neither. RAD-140 is a compact organic molecule without a steroid skeleton. It shares its target — the androgen receptor — with anabolic steroids, but its structure is entirely different, and aromatase and 5-alpha-reductase cannot convert it the way they convert testosterone.

### Capsules or liquid — which suits my lab?

The capsules (60 × 10 mg) are convenient when a fixed, pre-measured unit helps; the 30 mL liquid at 20 mg/mL suits volumetric work and dilution series. Both come from HPLC-tested material with a Certificate of Analysis for the lot.

### How do you confirm purity?

Every lot is HPLC-tested to at least 98% and its identity checked, and you can view the lot's Certificate of Analysis on this page before buying. Independent studies keep finding mislabelled SARM products, which is exactly why we document every single lot.

### Is RAD-140 prohibited in sport?

Yes. WADA bans all SARMs, RAD-140 included, at all times under its anabolic agents category, and there are validated tests to detect them. Nothing on this page is meant to suggest using the compound in sport.
