Description
Our RAD-140 powder is 2,000 mg of testolone in a UV-resistant foil pouch. It’s the dry form of the same compound we sell as a liquid, for labs that prepare their own solutions.

What is RAD-140 powder?
RAD-140 (testolone) is a non-steroidal SARM that Radius Health developed around 2010. It binds the androgen receptor with a Ki of about 7 nM and is active when given orally, so there’s no need for injection in animal models.
Radius studied it for muscle wasting, then shifted toward breast cancer research.
RAD-140 powder in published research
The first major paper, from Miller and colleagues in 2011, showed RAD-140 built muscle in rats and monkeys with limited effect on the prostate. In the rat work, 3 mg/kg of RAD-140 matched the muscle effect of 1 mg/kg testosterone with about half the prostate effect.
Later studies found it protected neurons in rat models, and it slowed the growth of AR+/ER+ breast cancer cells in lab models. A small phase I trial in breast cancer patients reported raised liver enzymes in some participants. Read more on PubMed.

Measuring and storage
The pouch holds 2,000 mg of dry powder. Measuring tools aren’t included, so you’ll need an analytical balance that reads to at least 1 mg for accurate work. Weigh in a draft-free spot and reseal the pouch straight away.
Most labs dissolve SARM powders in PEG-400. Bringing the full 2,000 mg up to 133.3 mL with our PEG-400 gives 15 mg/mL, the same strength as our liquid version. Gentle warming and stirring help it dissolve. Store the sealed pouch in a cool, dry place away from light.
Lab testing and certificate of analysis
Our RAD-140 powder is tested by MZ Biolabs, an independent lab in Arizona, and packed in the USA. The current certificate of analysis is dated 10/17/2025 and reports 97.5% purity. If you need the full COA for your lab records, email us and we’ll send it before you order.
RAD-140 powder FAQ
Is RAD-140 powder the same as liquid testolone?
Yes, it’s the same compound before it’s dissolved. The liquid is 15 mg/mL in PEG-400.
What solvent works for RAD-140?
PEG-400 is the standard choice, and we sell USP-grade PEG-400.
Does RAD-140 suppress testosterone?
Studies report suppression of natural testosterone, so plan your research around it.
Why researchers buy from Sports Technology Labs
Research only works when the material matches the label. That’s why an independent lab (MZ Biolabs) checks every batch we sell, and it’s why we print the COA date and purity on each page. We bottle in the USA and pack liquids in UV-resistant glass with tamper-evident seals. If a COA ever doesn’t match, we don’t sell the batch.
