Blends

A blend is two or more peptides lyophilized together in a single vial, at a fixed ratio, rather than reconstituted separately and combined by hand. Research groups use them when the compounds in question are routinely studied together and consistency between vials matters more than the ability to vary each component independently.The combinations here follow the pairings that appear most often in the literature. BPC-157 with TB-500 is the standard pairing in tissue-repair models, where the two are studied for complementary mechanisms — see BPC-157 vs TB-500 for how they differ. GLOW and KLOW combine GHK-Cu with repair peptides, and KLOW adds KPV, studied in inflammatory and gut-barrier models.Handling. A blend reconstitutes exactly like a single-compound vial — add bacteriostatic water down the vial wall and swirl, never shake. Because the ratio is fixed at manufacture, the concentration of each component follows directly from the total volume added; the reconstitution calculator handles the arithmetic. Store lyophilized vials at −20°C (−4°F) and reconstituted material refrigerated.Every blend is tested as a finished vial rather than as separate inputs, so the certificate reflects what is actually in the container. All certificates are published in full, including the chromatogram. Research use only.
