What is the GLOW Blend?
GLOW pairs three peptides that are each studied in separate lines of regenerative research. GHK-Cu is a copper-binding tripeptide investigated in connective-tissue and matrix-remodeling models. BPC-157 is a 15-residue peptide studied in angiogenesis and cell-migration research. TB-500 corresponds to the actin-binding region of thymosin beta-4 and is examined in cytoskeletal-dynamics models.
Combining the three in one vial lets researchers study how copper-mediated matrix activity, cytoprotective signaling, and actin-dependent motility behave alongside one another under controlled in vitro conditions.
Each vial holds 70 mg of lyophilized blend: 50 mg GHK-Cu, 10 mg BPC-157, and 10 mg TB-500.

What Research Shows
Laboratory studies of the three GLOW components describe distinct but overlapping mechanisms across vascular, tissue-repair, and matrix models. The summary below maps each component to its verified source studies.
In vascular endothelial cell cultures, BPC-157 was associated with increased expression and internalization of VEGFR2 and with activation of the VEGFR2-Akt-eNOS pathway in tube-formation assays [1]. In tendon explant and fibroblast cultures, the same peptide was linked to greater fibroblast outgrowth, cell survival under oxidative stress, and migration through the FAK-paxillin pathway [2]. Both effects are covered further in the BPC-157 and TB-500 research overview.
GHK-Cu has been studied for copper-dependent activity in connective-tissue models. It was associated with stimulation of collagen synthesis in fibroblast cultures at picomolar to nanomolar concentrations [3], and gene-profiling work has linked it to modulation of a broad set of genes tied to tissue-repair and antioxidant pathways [4]. Additional context is available in the GHK-Cu peptide research overview.
TB-500 corresponds to the actin-binding region of thymosin beta-4, which sequesters monomeric G-actin and regulates filament assembly in structural studies [5]. In a full-thickness wound model, thymosin beta-4 was associated with increased reepithelialization and keratinocyte migration [6]. The full three-peptide combination is discussed in the GLOW peptide research article.

Certificate of Analysis (COA) for Every Batch
A Certificate of Analysis (COA) is a document that verifies a compound’s identity, purity, and batch quality through independent laboratory testing. Every compound from BioLongevity Labs ships with a COA tied to its specific batch, so researchers can confirm exactly what they received before it enters a protocol.
Each COA reports results from third-party laboratory analysis, including:
High-performance liquid chromatography (HPLC) for purity, typically confirmed at 99% or higher Liquid chromatography mass spectrometry (LC-MS) for molecular identity and mass confirmation Sterility and endotoxin screening where applicable Chemical contaminant and residual solvent checks
COAs are sourced from independent certified labs rather than in-house testing alone, giving researchers a verifiable record of molecular integrity for each batch. All compounds are supplied for research use only.
