View certificates of analysisEach compound in this bundle is analyzed by an accredited US third-party laboratory before it ships.
Purity and identity confirmed by MZ Biolabs (Tucson, AZ), a US DEA-licensed analytical facility, via HPLC purity analysis and mass-spectrometry identity confirmation under GLP standards.
Our third-party certificates of analysis are published on our website — no login required.
Both bottles are built to preserve compound integrity throughout your research timeline.
Quality control across the research-compound industry is inconsistent, which makes third-party verification essential. A 2017 analysis published in JAMA examined 44 products marketed online as SARMs and reported wide gaps between labels and contents.

Both compounds verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory, via HPLC and mass spectrometry.
Suspended in the highest grade solvents and bottled in America.
Bottled in glass to prevent leaching of plasticizers such as BPA.
Transparent business, standard payment methods, no misrepresentation.
A non-steroidal selective androgen receptor modulator (SARM). Mechanistically, it binds the androgen receptor with high affinity and tissue selectivity, distinguishing it from steroidal androgens. It was developed as an investigational compound by Radius Health, Inc. (ref. 1).
A non-steroidal anti-androgen (NSAA) that acts as an antagonist of the androgen receptor. Mechanistically, it binds the androgen receptor and blocks androgen binding without reducing circulating androgen levels. It was first developed by French researchers (Roussel Uclaf) and is formulated for atomized application in research contexts (ref. 2).
Both compounds remain experimental research chemicals, supplied strictly for laboratory research. Sports Technology Labs makes no claims regarding their effects, and nothing in this listing should be interpreted as describing outcomes in humans or animals.
RAD-140 and RU-58841 are investigational compounds. They are not approved by the FDA and are not dietary supplements, drugs, or food. Marketing them for human use is unlawful.
RAD-140 is prohibited by the World Anti-Doping Agency under S1 (Anabolic Agents — SARMs), banned in- and out-of-competition. RU-58841, as a non-steroidal anti-androgen, is not listed on the WADA Prohibited List (ref. 4).
In the United States, neither is a controlled substance and both may be legally purchased and possessed for laboratory research use.
Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds.
