Sourcing & quality Why source S23 from Sports Technology Labs 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. 52%contained the labeled compound 39%contained an unapproved drug 25%contained an unlabeled substance 9%contained no active ingredient Source: Van Wagoner et al., JAMA, 2017 (ref. 2). Third-party tested & certified Verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory, via HPLC and mass spectrometry. USP-grade PEG-400 Suspended in the highest grade carrier and bottled in America. Glass bottles, fixed glass droppers Prevents BPA leaching and avoids contamination from external tools. 60-day money-back guarantee Transparent business, standard payment methods, no misrepresentation. Research context What is S23? S23 is a non-steroidal selective androgen receptor modulator (SARM). Mechanistically, it binds the androgen receptor with high affinity and tissue selectivity, which distinguishes it from steroidal androgens. It is orally bioavailable in study models and was characterized as an experimental compound through programs associated with GTx, Inc. (ref. 1). S23 remains an experimental research chemical and is 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. Regulatory & compliance status Important regulatory information Not approved for human use S23 is an investigational compound. It is not approved by the FDA and is not a dietary supplement, drug, or food. Marketing it for human ingestion is unlawful. WADA-prohibited Listed by the World Anti-Doping Agency under S1 (Anabolic Agents — Selective Androgen Receptor Modulators), banned both in- and out-of-competition (ref. 3). Legal status for research In the United States, S23 is not a controlled substance and may be legally purchased and possessed for laboratory research use. Our position Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds.
