Glow Blend is supplied as a laboratory research reference material for in-vitro and laboratory research use only. Presented under catalog identifier Glow-Blend, this three-peptide complex combines BPC-157, TB-500 (thymosin beta-4 fragment), and GHK-Cu (glycyl-L-histidyl-L-lysine copper tripeptide) in a single lyophilized preparation intended for comparative peptide chemistry, chromatographic method development, and reference-standard workflows.
The Glow Blend composition brings together three structurally distinct synthetic peptides. BPC-157 is a 15-residue pentadecapeptide sequence (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) derived from a partial sequence of gastric juice protein. TB-500 is a synthetic 17-mer acetylated fragment corresponding to the active region of thymosin beta-4. GHK-Cu is a copper(II)-complexed tripeptide in which the Gly-His-Lys sequence chelates a divalent copper ion, imparting the characteristic blue-tinted hue observed in concentrated GHK-Cu solutions; in a co-lyophilized blend this may modestly influence the visual appearance of the reconstituted matrix. All three components in Glow Blend are of synthetic origin, produced by solid-phase peptide synthesis and supplied as a co-lyophilized white to off-white powder.
Analytical identity and purity of Glow Blend are documented on the lot-specific Certificate of Analysis, with each component assessed at not less than 98% by HPLC. Typical characterization protocols employed by peptide analytical laboratories include reversed-phase HPLC for component resolution and purity, ESI or MALDI mass spectrometry for molecular-weight confirmation of each constituent peptide, and residual-solvent and water-content testing as appropriate to the lyophilizate. The presence of the copper-chelated GHK-Cu component provides a useful internal reference for UV-Vis and ICP-based metal-content assays alongside the two non-metallated peptides.
Published scientific literature has examined Glow Blend and its individual constituents in preclinical research contexts, and investigators frequently select multi-peptide reference materials of this type for method cross-validation, retention-time mapping, and stability-indicating assay development. PEPTIDE.Power makes no therapeutic, diagnostic, or efficacy claims regarding this material and provides no administration or dosing guidance. This material is not a drug, supplement, cosmetic, or food, and is not for human or veterinary use, injection, or ingestion. A lot-specific Certificate of Analysis for Glow Blend is available on request to support qualification within the receiving laboratory’s quality system.
