Liquid RAD-140 (Testolone) 15mg/mL

Description

Liquid RAD-140 from Sports Technology Labs is RAD-140 (testolone) dissolved in USP-grade PEG-400 at 15mg/mL, in a 30mL glass bottle. RAD-140 is a nonsteroidal selective androgen receptor modulator (SARM). It’s intended for lab and analytical work only.

What is RAD-140 (testolone)?

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.

The mechanism behind RAD-140

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.

What the literature says about RAD-140

The founding paper is Miller and colleagues, ACS Medicinal Chemistry Letters, 2011, which described RAD-140’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.

Where RAD-140 fits in the range

Quick context: RAD-140 is a potent nonsteroidal SARM from Radius Health, later tested in breast cancer. Other compounds in the same area:

• Ostarine is the most studied SARM, with human trial data on muscle wasting
• LGD-4033 binds the androgen receptor very tightly and has a phase 1 study in healthy men
• RAD-150 is a benzoate ester of RAD-140 with no published studies of its own
• S4 (andarine) is an early partial-agonist SARM from GTx with rat data on muscle and bone
• S23 is a high-affinity SARM studied as a male contraceptive in rats

All of them bind the androgen receptor, but affinity, selectivity and the amount of published data differ a lot. Compare them in our liquid SARMs.

Liquid RAD-140 concentration and measuring

The bottle is 30mL at 15mg per mL (450mg total), dissolved in USP-grade PEG-400 and supplied with a graduated 1mL pipette.

Measuring is simple arithmetic: 0.5mL holds 7.5mg and 0.1mL holds 1.5mg. Read the pipette at eye level, since PEG-400 is thick and clings to the glass.

Storing Liquid RAD-140

Store it at room temperature or cooler, capped, away from light and heat. There’s no need to refrigerate it, and cold makes the PEG-400 even thicker to measure.

Shake the bottle gently before drawing if it has been sitting for a while.

Liquid RAD-140 purity and lab testing

The current certificate of analysis shows 97.47% by HPLC. The testing is done by MZ Biolabs, an independent lab in Tucson, Arizona, which also checks identity by mass spectrometry.

Scroll through the product photos and the certificate is there, with the test date and the chromatogram.

Why two tests? A sample can be very pure and still be the wrong compound. HPLC measures purity and mass spec confirms the molecular weight, so together they cover both problems.
