Mechanism of action
Glow has no mechanistic literature of its own; activity is inferred from the three components. GHK-Cu is a copper-binding tripeptide originally isolated from human plasma (Pickart 1973) that upregulates collagen, glycosaminoglycan, decorin, and elastin synthesis in dermal fibroblasts at picomolar-to-nanomolar concentrations, modulates matrix metalloproteinase activity, and has been shown by transcriptomic profiling to shift gene expression of more than 4,000 human genes toward a youthful pattern (Pickart & Margolina, 2018, PMC6073405; PMC4508379).

BPC-157 contributes VEGFR2-mediated angiogenesis and Akt/eNOS-driven nitric-oxide signaling, supporting fibroblast activity and connective-tissue remodeling (Sikiric et al., PMID 20388964). TB-500 (thymosin beta-4 active-site fragment) is the principal G-actin-sequestering peptide in cells and accelerates wound re-epithelialization through promotion of cell migration, progenitor mobilization, and anti-inflammatory signaling (Goldstein et al., PMID 22074294; Crockford et al., PMID 23050815). The blend is positioned for synergy across collagen/ECM remodeling, angiogenesis, and cell migration, but no direct evidence of synergy in humans has been published.
Use & research dosing
Research framing only. Community self-experimentation protocols typically dose roughly 200-500 mcg of each component subcutaneously per day, or a combined 1-2 mg per injection split across the three peptides, run in 4-8 week cycles followed by an off-period. Topical compounded formulations vary widely between compounders in per-component concentration and base vehicle. GHK-Cu has the broadest cosmetic-dermatology dosing precedent, typically 0.005-2% by weight in topical formulations, while BPC-157 and TB-500 lack any validated topical dose and their dermal penetration is poorly characterized. No human dose-finding study exists for the blended product. Vendors do not consistently disclose the per-component mass split in their vials, and independent assay verification is rare.
