About GLOW Blend
GHK-Cu, BPC-157 and TB-500 blended for skin-matrix research.
Supplied as
70 mg per vial, as a lyophilized powder in a sealed glass vial with a crimped cap. The lot number on the label matches the certificate of analysis in the COA library.
Storage and handling
Store lyophilized powder frozen (−20 °C) or refrigerated, sealed and away from light. Once reconstituted, keep refrigerated (2–8 °C).
Handle in a laboratory setting using appropriate protective equipment. Consult the certificate of analysis and safety data for lot-specific information.

Research summary
GLOW Blend is a research blend of three peptides in one lyophilized vial: the copper peptide GHK-Cu, BPC-157 and TB-500. Each component has its own preclinical literature in skin-matrix and tissue-repair models, but no published study has tested this combination, so the research behind GLOW is the research behind its parts.
- Also known as
- GLOW peptide blend · GHK-Cu + BPC-157 + TB-500 blend
What is in GLOW Blend?
GLOW Blend contains three peptides. In effect it is the Wolverine Blend pair, BPC-157 and TB-500, plus GHK-Cu; KLOW Blend contains the same three plus a fourth, KPV.
- GHK-Cu: the copper(II) complex of Gly-His-Lys, a tripeptide isolated from human plasma and studied for collagen and glycosaminoglycan synthesis1,2.
- BPC-157: a 15-amino-acid partial sequence of a protein found in human gastric juice, studied in rat tendon and skin-wound models3,4.
- TB-500: the N-acetylated peptide LKKTETQ, a synthetic version of the actin-binding region of thymosin beta-45,6.
Why these peptides are studied together
The rationale is that each component is studied at a different step of tissue repair. GHK-Cu research centers on the extracellular matrix: it stimulated collagen synthesis in fibroblast cultures at nanomolar concentrations1 and increased collagen and glycosaminoglycan accumulation in rat wound chambers2. BPC-157 research centers on cell behavior: it increased the outgrowth, survival under oxidative stress and migration of rat tendon fibroblasts, with activation of the FAK-paxillin pathway3. Thymosin beta-4 research centers on migration and new vessel growth: in full-thickness rat wounds it increased re-epithelialization, collagen deposition and angiogenesis, and it stimulated keratinocyte migration7.
That is a hypothesis about complementary mechanisms, not a tested result. The one controlled study that combined two of these peptides, BPC-157 and TB-500 in a rat Achilles tendon model, found no additional effect from the combination compared with either peptide alone8.
Limitations of the evidence
- No published study has examined GLOW Blend, or GHK-Cu combined with BPC-157 and TB-500, in any model.
- Most thymosin data come from the full-length 43-residue protein6. A 2024 study found that in fibroblast assays a TB-500 metabolite, Ac-LKKTE, rather than the parent peptide, showed significant wound-closure activity9.
- Clinical evidence for GHK-Cu is sparse10, and human evidence for BPC-157 consists of a few small studies rated very low certainty11.
Sourcing GLOW Blend for research
Peptides Only supplies GLOW Blend as a lyophilized powder for laboratory research only. Each lot ships with a lot-matched certificate of analysis (HPLC purity and mass-spec identity) from an independent lab, published in our COA library. For designs that need to separate the effect of each peptide, the components are also sold individually, and GLOW vs KLOW vs Wolverine sets the three blends side by side.
GLOW Blend FAQ
What is the difference between GLOW and KLOW?
KLOW contains everything in GLOW (GHK-Cu, BPC-157 and TB-500) plus KPV, the C-terminal tripeptide of alpha-MSH, which is studied in inflammation models12. Neither blend has been studied as a mixture.
What is the difference between GLOW and Wolverine Blend?
Wolverine Blend contains only BPC-157 and TB-500. GLOW adds GHK-Cu, whose research focuses on collagen synthesis and extracellular-matrix accumulation1,2.
Has GLOW Blend been tested in clinical trials?
No. There are no clinical trials or animal studies of GLOW Blend as a product; the published research concerns its individual components.
Is GLOW Blend approved by the FDA?
No. None of its components is an approved drug: BPC-157 lacks regulatory approval for human use11, GHK-Cu is regarded as an unproven therapeutic agent10, and TB-500 originated as a veterinary preparation that equine doping-control laboratories test for5. GLOW Blend is sold for laboratory research only.
