Sourcing & quality Why source Cardarine 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 Cardarine (GW-501516)? Cardarine (GW-501516) is a synthetic, non-steroidal PPARδ (peroxisome proliferator-activated receptor delta) agonist. Mechanistically, it binds and activates the PPARδ nuclear receptor, which regulates the transcription of genes involved in lipid and energy metabolism. It was developed through pharmaceutical research programs, including those at GlaxoSmithKline, beginning in the early 1990s (ref. 1). Although GW-501516 is frequently catalogued and sold alongside selective androgen receptor modulators (SARMs), this is a cataloguing convention rather than a pharmacological classification: it is mechanistically distinct and does not bind the androgen receptor. It remains 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. Regulatory & compliance status Important regulatory information Not approved for human use GW-501516 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 S4 (Hormone and Metabolic Modulators) as a PPARδ agonist, banned both in- and out-of-competition (ref. 3). Legal status for research In the United States, GW-501516 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.
