Products & Quality
All Hotspan Labs products are strictly for in vitro laboratory research and experimentation. They are not intended for human consumption, veterinary use, or therapeutic application. By purchasing, you confirm you are a qualified researcher using these compounds within a laboratory setting in accordance with applicable regulations.
We guarantee ≥99% purity on all peptides, verified by independent third-party HPLC and Mass Spectrometry analysis. A Certificate of Analysis (COA) from the testing laboratory is available for every batch — downloadable directly from each product page.
All peptides are synthesized in USA-registered facilities following Good Manufacturing Practices (GMP). We do not source from overseas manufacturers. Full chain of custody documentation is maintained and available on request.
A COA is a document issued by an independent, CLIA-certified laboratory confirming the identity, purity, and potency of a given batch. Our COAs include HPLC chromatograms, mass spectrometry data, endotoxin results, and the testing chemist's signature. Every batch receives its own COA — we do not use generic or shared documentation.
Yes — free BAC (bacteriostatic) water is included with qualifying orders. BAC water is the appropriate reconstitution solvent for most research peptides. It is also available separately in the Reconstitution section of our catalog.
Lyophilized (freeze-dried) peptides are stable at room temperature for shipping and long-term storage at -20°C. Reconstituted peptides are dissolved in a solvent (typically BAC water) and ready for use. We ship all products in lyophilized form for stability.
