Independently verified99.57% pure
Every batch 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.
Every COA is published openly, batch-dated, and matched to the product you receive — no login required.
Each bottle is formulated and verified for consistent label-to-bottle accuracy across studies.
Storage & handling
Built to preserve compound integrity throughout your research timeline.
- Storage: Keep in a cool, dry place away from direct sunlight to maximize shelf life.
- UV-resistant glass bottle with fixed glass dropper to minimize degradation and avoid plasticizer (BPA) leaching.
- Tamper-proof seal to ensure integrity in transit.
- Graduated 1 mL glass pipette included for precise measurement.
- Evaporation-resistant formulation and packaging for stable storage.
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.

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.
Important regulatory information
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.
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).
In the United States, GW-501516 is not a controlled substance and 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.
