RAD-140 Capsules 10mg

RAD-140 from Onyx Research are capsules holding 10mg of RAD-140 each, in 60-count or 100-count bottles. RAD-140 is a nonsteroidal selective androgen receptor modulator (SARM). It’s meant for lab and analytical work only.

Capsules need no mixing. Each one is filled with a set amount, so you skip the water, the syringe and the arithmetic.

This compound is a selective androgen receptor modulator (SARM), a small molecule, so it’s sold in capsules. Vanguard Laboratory checked the 10mg-per-capsule amount for us.

RAD-140 lab report

The product photos include a certificate of analysis from Vanguard Laboratory, report V260302-3, dated 3/13/2026. The lab checked the amount per capsule by HPLC with UV-VIS detection and reported 10mg per unit, which matches the label.

About RAD-140

RAD-140 (testolone, also called vosilasarm) is a nonsteroidal SARM developed by Radius Health. In preclinical work it showed strong activity in muscle with much less effect on the prostate and seminal vesicles than testosterone.

Radius later studied it in breast cancer, where it acts on androgen receptors in tumor cells. It isn’t an approved medicine.

How it works

RAD-140 binds the androgen receptor and drives androgen-responsive gene activity in muscle and bone, with partial activity in the prostate. In monkeys it raised lean mass at exposures that left prostate size mostly unchanged.

In ER-positive breast cancer cells, switching on the androgen receptor holds back estrogen-driven growth, which is why Radius tested it there. Rodent work also suggested it protects neurons in culture.

Planning a study with capsules

Capsules make a protocol easy to repeat. Two researchers following the same plan start from the same amount, with no weighing or dilution in between.

Every step up or down is another 10mg. You can open and split a capsule, but then you lose the consistency that made capsules attractive.

The 60-count bottle costs $200.00 and the 100-count bottle $250.00, so the larger bottle works out cheaper per capsule. Pick the count from the option menu.

Storage and handling

Keep the lid tight and the bottle somewhere cool, dry and out of the sun. Leave any desiccant pack inside. Dry gloves stop moisture from softening the shells.

Note the date the bottle arrived and the date you opened it. If you portion capsules out to different experiments, label each portion.

Published studies

The founding paper is Miller and colleagues, ACS Medicinal Chemistry Letters, 2011, which described the product’s discovery and its tissue selectivity in rats and monkeys.

A phase 1 trial in women with advanced ER-positive, HER2-negative breast cancer reported its pharmacokinetics and side effects, including liver enzyme rises in some patients.

The papers are free to read via this PubMed search for RAD-140 from the U.S. National Library of Medicine.

Ordering RAD-140
