Co-lyophilized BPC-157 / TB-500 / GHK-Cu multi-peptide research blend
Overview
GLOW is a fixed-ratio multi-peptide preparation combining three separately characterized species: BPC-157, the acetylated thymosin beta-4 (17-23) fragment TB-500 (Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln), and the copper tripeptide GHK-Cu (Gly-His-Lys complexed with Cu2+). It is co-lyophilized as one cake so the three components stay in their intended proportion on reconstitution. Each constituent carries its own individual research literature, largely in skin-rejuvenation and anti-aging contexts, while the fixed-ratio combination itself has not been evaluated in formal controlled studies, which is why the per-component amounts must be worked out carefully rather than assumed. Lyochem supplies GLOW as a lyophilized reference standard at >=99.0% HPLC per resolvable peptide component, characterized on a per-component basis rather than as a single lumped value. The released COA reports the identity and share of each of the three peptides by RP-HPLC and LC-MS mapping, with ESI-MS confirmation of the individual masses and ICP-MS copper quantitation for the GHK-Cu fraction. Honest composition is the point of this listing: the specific per-component breakdown and ratio are printed on the batch COA rather than hidden behind a proprietary label.
Applications & buyer fit
Repair peptides — BPC-157, TB-500, B7-33, PEG-MGF — ship primarily to research labs studying tissue-repair, gastrointestinal-mucosa, tendon-ligament, and vascular-endothelial models. The synthesis itself is reliable, but analytical confirmation is where suppliers differ: buyers qualifying a new source should request sequence verification by tandem MS on the first lot and compare against the labelled sequence directly.
Academic Laboratories
Universities, medical schools, and government research institutes qualifying a reference standard for a method-development or in vivo workflow.
Biotech R&D Groups
Preclinical biotech and pharmaceutical discovery teams sourcing characterized peptides for receptor-pharmacology, screening, and method-development campaigns.
Every release ships with its own batch-specific CoA — identity, purity, and the analytical scope agreed at quote stage, tied to the exact lot you receive.
Review a representative batch CoA before you order, so you can confirm the packet matches what your method or sponsor audit needs.
Supplied strictly as a research reagent to research institutions — not a finished dosage form and not for human administration. Buyer qualification runs at the inquiry stage.

Regulatory note
Lyochem provides GLOW strictly as a laboratory research blend for in-vitro characterization. Because it is a multi-component mixture and not a defined single molecule, it is unsuitable for and not offered for any human, clinical, or veterinary purpose.
Frequently asked questions
Yes. Unlike a sealed proprietary blend, our COA states each of the three peptides (BPC-157, TB-500, GHK-Cu) with its measured content and the ratio between them, determined by RP-HPLC and LC-MS. Nothing about the composition is withheld under NDA; the numbers a lab needs to plan dosing per component are on the released certificate.
Because the constituents differ in mass and retention, they resolve on a single LC-MS peptide-mapping run: each peak is assigned by ESI-MS to its expected mass and quantified for relative share. The copper-bound GHK-Cu fraction is additionally checked by ICP-MS, so the certificate documents each component independently rather than reporting only a total peptide figure.
