Liquid Testolone (RAD-140) 15 mg/mL

Description

Liquid testolone is RAD-140 dissolved in USP-grade PEG-400 at 15 mg/mL. That’s 450 mg in each 30 mL bottle. The dropper is fixed into the cap, so you can draw a measured volume without pipettes or syringes.

Testolone is one of the strongest compounds in our liquid SARMs collection. If you’d rather weigh it, there’s RAD-140 powder. Researchers looking at its longer-acting cousin can try liquid RAD-150, and RAD-140 is in four of our stacks, including the RAD-140 and MK-677 stack.

What is liquid testolone?

Testolone (RAD-140) is a non-steroidal SARM developed by Radius Health around 2010. It binds the androgen receptor with a Ki of about 7 nM, which is stronger than testosterone in the same assays, and it’s orally bioavailable.

Radius first looked at it for muscle wasting and osteoporosis. Later work focused on breast cancer, because RAD-140 acts as an androgen receptor agonist in breast tissue that also carries estrogen receptors.

Testolone research in animals and cells

In young male monkeys, RAD-140 raised lean body mass over 28 days with little effect on the prostate. Rat studies found that 3 mg/kg of RAD-140 built muscle about as well as 1 mg/kg of testosterone, with roughly half the androgenic effect on the prostate. Other rat work found it protected hippocampal neurons in culture and in vivo.

A phase I trial in women with advanced AR+/ER+ breast cancer was completed in 2020. Some participants reported raised liver enzymes. Testolone isn’t approved for any use, and you can read the studies on PubMed.

Measuring and storage

At 15 mg/mL the math is simple: 1 mL holds 15 mg, 0.5 mL holds 7.5 mg and 0.25 mL holds 3.75 mg. The full 30 mL bottle holds 450 mg. Draw from the fixed glass dropper and read the volume at eye level.

Keep the cap tight and store the bottle upright in a cool, dry place out of direct sunlight. PEG-400 doesn’t need refrigeration. If the solution looks cloudy after cold shipping, let it sit at room temperature and swirl it gently.

Lab testing and certificate of analysis

Every batch of liquid testolone is tested by MZ Biolabs, an independent lab in Arizona, and bottled in the USA. The current certificate of analysis is dated 10/17/2025. Ask us for the full COA and we’ll send it over before you place an order.

Liquid testolone FAQ

What’s the difference between liquid testolone and RAD-150?

RAD-150 is RAD-140 with a benzoate ester attached. The ester is meant to give a longer, steadier half-life. RAD-140 has far more published research.

Does RAD-140 suppress testosterone?

A 2010 study reported suppression of natural testosterone after 28 days at all doses tested, so suppression should be expected.

Can I buy RAD-140 as a powder?

Yes, RAD-140 powder comes in a 2 gram UV-resistant pouch.

Why researchers buy from Sports Technology Labs

A 2017 JAMA study bought 44 products sold online as SARMs and tested them. Only 52% contained a SARM at all, and 39% contained other unapproved drugs. That’s the problem we set out to fix. We start with raw material that’s at least 98% pure, bottle everything in the USA and send every batch to MZ Biolabs before it goes on sale. Liquids go into glass bottles with glass droppers, so there’s no plastic in contact with the solution.

Shipping, returns and support

Orders over $149 ship free inside the US, and express shipping is there at checkout if you’re short on time. Everything we sell is covered by a 60-day money-back guarantee. Questions about a batch, a COA or an order? Email us and a real person will answer.

For laboratory research use only

Liquid testolone is supplied strictly for laboratory and analytical research. It is not approved by the FDA, is not a dietary supplement and must not be used in people or animals. Nothing here is medical advice, and we won’t sell it for personal or athletic use.
