Every lot is documented
Each batch we receive is accompanied by an HPLC chromatogram establishing purity, a mass spectrometry report confirming identity, and a residual solvent screen. We keep these on file and link the current lot on the product page.
Storage and handling
Lyophilised peptides are held at −20 °C in the dark and shipped in insulated packaging. Cosmetics and supplements are stored at ambient temperature away from direct light.
What we do not claim
Research peptides are supplied for in-vitro laboratory work. We make no medical claims about them, and we do not provide dosing guidance for human use — because there is none to give.
