Spartan contains GW-501516 at a labeled dosage of 25 mg per capsule, intended for laboratory research purposes only.

Quantitative testing found 28.22 mg/CAP, indicating a slightly overfilled capsule relative to the label. This suggests consistent or possibly conservative formulation practices for research-grade reliability.

High-Performance Liquid Chromatography with UV/Visible detection (HPLC-UV/VIS) was used to quantify GW-501516 content, which is standard for verifying compound purity and concentration.

The report includes a chromatogram trace showing peak retention time at approximately 8.74 min, aligning with known standards for Cardarine. Minimal signal noise or unexpected peaks were detected, supporting compound integrity.

 These identifiers ensure the compound is traceable back to its testing instance and batch, which is essential for regulated research environments.

Testing was conducted by Vanguard Laboratory, an ISO/IEC 17025:2017 accredited facility. While they confirm results on the tested sample, they do not validate the full batch, and results should be interpreted accordingly in controlled settings.
