Identity
Each lot is confirmed by mass spectrometry against the published molecular formula.
Quality
Labeled. Pure. Tested.
Every peptide is tested before it is listed, and every vial is labeled. A paper certificate does not ship in the box.
Purity
Release specification is ≥99% by HPLC. Every peptide is pure and tested. We do not sell material below that floor.
Residual solvents & metals
Lots are screened for residual solvents and a heavy-metals panel.
Endotoxin
Where the intended assay is cell-based, we can supply endotoxin data. It is a laboratory specification, not a sterility claim for clinical use.
Form
Peptide lots are a lyophilized cake in a sealed crimp vial. Store at −20 °C, protected from light and moisture. We do not ship peptides already reconstituted. Bacteriostatic water is sold separately as a clear laboratory solvent.
What we will not do
No human-use claims. No veterinary claims. No compounding or dosing advice. No syringes or administration kits. Bacteriostatic water is a lab solvent, not instructions for use.
