Storage & handling
Store per standard laboratory practice for liquid research chemicals.
- Storage conditions: Store in a cool, dry place away from direct sunlight to maximize shelf life.
- UV-resistant glass bottle with a fixed glass dropper, to limit photodegradation and avoid plasticizer leaching (e.g. BPA).
- Graduated 1 mL glass pipette included for precise measurement.
- USP-grade PEG-400 base — pharmaceutical-grade solvent carrier, bottled in America.
- Tamper-proof seal, with formulation designed to limit evaporation and hold less than 5% concentration variance.
Why source RAD-140 from Sports Technology Labs
Quality control in the SARM market is notoriously inconsistent. A peer-reviewed analysis published in JAMA examined 44 products sold online as selective androgen receptor modulators and found that labels frequently did not match contents:
Figures from Van Wagoner et al., JAMA 2017 (ref. 3). Independent third-party verification is essential for reproducible SARM research.
Verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory, via HPLC and mass spectrometry; current posted COA reports 97.47%.
Suspended in pharmaceutical-grade PEG-400 and bottled in the USA.
With a graduated 1 mL glass pipette included, to prevent plasticizer leaching and cross-contamination.
Transparent business, standard payment methods, no misrepresentation.
What is RAD-140?
RAD-140 (Testolone) is a non-steroidal selective androgen receptor modulator (SARM), developed by Radius Health as an investigational compound. Mechanistically, it binds the androgen receptor (AR) with high affinity and tissue selectivity, and it is orally bioavailable.
It should not be confused with its esterified form, RAD-150 (TLB-150). RAD-140 is used as a research chemical to investigate androgen-receptor pharmacology in experimental models.
RAD-140 is an experimental research chemical, supplied strictly for laboratory research. Sports Technology Labs makes no claims regarding its effects, and nothing in this listing should be interpreted as describing outcomes in humans or animals.
Important regulatory information
RAD-140 is an investigational compound awaiting FDA approval. It is not a drug, food, dietary supplement, or cosmetic, and is not approved for human use. Marketing it for human ingestion is unlawful.
RAD-140 is a SARM and is prohibited by the World Anti-Doping Agency at all times under S1.2 (Other Anabolic Agents), the class that includes selective androgen receptor modulators (ref. 4).
In the United States, RAD-140 is not currently a federally scheduled controlled substance and may be legally purchased and possessed for laboratory research use. State and institutional rules may apply.
Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds, and we discourage SARM use for performance enhancement.
