Blends

A blend is two or more peptides lyophilized together in a single vial, at a fixed ratio, rather than prepared 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 is handled exactly like a single-compound vial. Bacteriostatic water is the standard laboratory diluent. Because the ratio is fixed at manufacture, the concentration of each component follows directly from the total volume added. Store lyophilized vials at −20°C (−4°F) and keep refrigerated once in solution.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.
