Peptide blends supply more than one compound in a single vial. The useful thing to understand about them is that the mass on the label is the total across the blend, divided between the components — not the amount of each.That matters when comparing a blend against single-compound literature, because the amount of any one peptide present is a fraction of the stated figure. Where a blend’s composition is published on its certificate, we state the proportions on the product page rather than leaving them implied — the Klow guide is a worked example.Blends should be reconstituted and stored according to their most demanding component. All products are sold for laboratory research use only.
