The Glow Stack (BPC-157 + TB-500 + GHK-Cu) – 70mg Triple-Peptide Research Blend | Peptides Lab UK

The Glow Stack is a 70mg triple-peptide research blend combining BPC-157 (Body Protective Compound-157), TB-500 (Thymosin Beta-4 fragment), and GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) — three of the most extensively studied peptides in tissue repair, collagen synthesis, and cellular regeneration research — supplied by Peptides Lab UK in lyophilised format at >99% purity (HPLC verified) for in vitro and pre-clinical laboratory research use only.

Available to buy in the UK from Peptides Lab UK, the Glow Stack brings together three peptide compounds whose published research profiles converge on overlapping yet complementary biological pathways — including angiogenesis, extracellular matrix remodelling, fibroblast activation, keratinocyte migration, and collagen and elastin synthesis. Each batch undergoes rigorous quality analysis to ensure consistent blend composition and >99% purity across all three active peptides.

What is the Glow Stack?

The Glow Stack is a multi-peptide research preparation formulated as a 70mg lyophilised blend of three structurally and functionally distinct peptides: BPC-157, TB-500, and GHK-Cu. While each compound has a well-established independent research literature, their combination in a single preparation is designed to allow researchers to study the potential synergistic interactions of complementary tissue-repair and cellular regeneration pathways simultaneously in controlled in vitro and pre-clinical experimental settings.

Each compound in the Glow Stack operates through distinct — but overlapping — primary mechanisms. BPC-157 activates ERK1/2, VEGFR2, and nitric oxide signalling pathways to promote angiogenesis and fibroblast activity. TB-500 (the Thymosin Beta-4 fragment) sequesters actin, drives cell migration and stem cell mobilisation, and reduces apoptosis and inflammation. GHK-Cu acts as a copper-binding signalling peptide that modulates the expression of thousands of genes involved in collagen remodelling, antioxidant defence, and tissue repair. Together, these three mechanisms span the key stages of the wound healing and tissue regeneration cascade — from initial vascular response and inflammation modulation through to matrix remodelling and re-epithelialisation — making the Glow Stack a unique tool for multi-pathway tissue biology research.

What Does the Glow Stack Do in Research?

In laboratory and pre-clinical research settings, the three peptides in the Glow Stack are each studied for their individual effects on tissue repair and regeneration pathways. When studied in combination, the blend allows researchers to investigate whether BPC-157’s pro-angiogenic and fibroblast-activating effects, TB-500’s cell-migration and stem cell-mobilising properties, and GHK-Cu’s collagen-remodelling and gene-expression-modulating activity produce additive or potentiating outcomes in controlled experimental models.

The three peptides act at different — yet complementary — stages of the tissue repair cascade. BPC-157 operates primarily at the vascular and fibroblast level, driving the early angiogenic response and connective tissue rebuilding. TB-500 drives cellular mobilisation, particularly promoting the migration of keratinocytes, endothelial cells, and stem/progenitor cells to sites of tissue disruption, while simultaneously suppressing inflammatory and apoptotic signalling. GHK-Cu acts at the extracellular matrix (ECM) level, modulating the balance between matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) to regulate collagen turnover, and stimulating fibroblasts to produce collagen type I, collagen type III, and elastin.

Key Research Areas for the Glow Stack

What Do Studies Say About the Glow Stack Peptides?

Each of the three peptides in the Glow Stack has a strong, independent body of published pre-clinical and clinical research. The studies below cover the key findings for each compound individually.

BPC-157 (Body Protective Compound-157) Research

Wound Healing & Collagen Formation (PubMed / ScienceDirect, 1997)

One of the earliest published studies of BPC-157’s tissue effects used three experimental rat models — skin incisional wounds, colon-colon anastomoses, and synthetic sponge implantation — to assess its influence on granulation tissue formation, collagen production, angiogenesis, and tensile strength development. Specimens were histologically assessed for collagen, reticulin, and blood vessels. Significant differences between BPC-157-treated animals and controls were found across all three models, with the authors describing a strong, promoting involvement of BPC-157 in the healing process. Notably, effects were achieved via multiple routes of application including intragastric and local, suggesting broad applicability across experimental delivery methods.

ERK1/2, VEGFR2 & Angiogenesis Signalling Review (PMC, 2025)

A 2025 scoping review published in PMC evaluated BPC-157’s molecular mechanisms in musculoskeletal healing. The review confirmed that BPC-157 activates VEGFR2 and drives nitric oxide synthesis via the Akt-eNOS axis, promoting angiogenesis, fibroblast activity, and neuromuscular stabilisation. In endothelial cell models, BPC-157 significantly enhanced ERK1/2 phosphorylation in a dose-dependent manner, leading to increased cellular proliferation, migration, and vascular tube formation. These effects were mediated through downstream activation of transcription factors including c-Fos, c-Jun, and EGR-1, which regulate genes involved in cell cycle progression, extracellular matrix remodelling, and angiogenic signalling.

Alkali-Burn Wound Healing, VEGF-A & ERK1/2 (PMC / Dove Press, 2015)

A controlled study published in PMC and Dove Press investigated BPC-157’s effects on alkali-burn wound healing in vivo and on HUVEC (human umbilical vein endothelial cell) behaviour in vitro. BPC-157 was found to be effective in the very low dose range, accelerating wound healing with better granulation tissue formation, re-epithelialisation, dermal remodelling, and higher collagen deposition than the model control group at day 18. BPC-157 also promoted VEGF-a expression in wounded skin tissues, enhanced HUVEC proliferation and migration, and accelerated vascular tube formation in vitro. The study confirmed that BPC-157’s effects on tube formation were mediated via the ERK1/2 signalling pathway, as its effects were significantly inhibited by the ERK1/2 inhibitor PD98059.

TB-500 (Thymosin Beta-4) Research

Wound Healing, Angiogenesis & Keratinocyte Migration (PubMed, 1999)

A foundational pre-clinical study published on PubMed investigated Thymosin Beta-4 (TB4) in a rat full-thickness wound model. Topical and intraperitoneal addition of TB4 increased re-epithelialisation by 42% over saline controls at day 4, and by up to 61% at day 7 post-wounding. Treated wounds contracted at least 11% more than controls by day 7, and increased collagen deposition and angiogenesis were observed. In the Boyden chamber assay, TB4 stimulated keratinocyte migration 2–3-fold over medium alone after just 4–5 hours, with as little as 10 pg of TB4 sufficient to produce a potent stimulatory response. The authors described TB4 as a potent wound healing factor with multiple activities.

Reference: Malinda KM et al. (1999). Thymosin beta4 accelerates wound healing. Journal of Investigative Dermatology. PubMed PMID: 10469335.

Multi-Functional Regenerative Peptide Review (PubMed, 2012)

A comprehensive review published on PubMed examined the structure, biological properties, and clinical applications of Thymosin Beta-4. The review confirmed that TB4 is released by platelets, macrophages, and many other cell types following injury, where it protects cells and tissues from further damage and reduces apoptosis, inflammation, and microbial growth. It binds to actin and promotes cell migration — including the mobilisation, migration, and differentiation of stem/progenitor cells that form new blood vessels and regenerate tissue. The review also described TB4’s ability to decrease the number of myofibroblasts in wounds, resulting in decreased scar formation and fibrosis. The authors cited the scientific foundation provided by these studies as supporting ongoing and projected clinical trials in dermal wound repair, corneal injuries, and cardiac and CNS tissue regeneration.

Dermal Healing Acceleration — Pre-Clinical Models & Phase 2 Trials (PubMed, 2012)

A review of Thymosin Beta-4’s pre-clinical and clinical dermal healing evidence published on PubMed confirmed that TB4 accelerated dermal healing of full-thickness punch wounds across a wide range of animal models — including normal rats and mice, steroid-treated rats, diabetic mice, and aged mice. It was also found to be active in burn models. In two Phase 2 clinical trials covering stasis and pressure ulcers, TB4 accelerated healing by almost a month in patients who achieved complete wound closure. The authors concluded that TB4 is a multifunctional regenerative peptide important in dermal repair, acting through promotion of cell migration, stem cell mobilisation and differentiation, and inhibition of inflammation and apoptosis.

GHK-Cu (Copper Tripeptide-1) Research

Gene Expression, Collagen Synthesis & Skin Regeneration Review (PMC, 2018)

A comprehensive review published in PMC examined GHK-Cu’s multi-pathway actions in the light of new gene profiling data. The review confirmed that GHK-Cu stimulates blood vessel and nerve outgrowth, increases collagen, elastin, and glycosaminoglycan synthesis, and supports dermal fibroblast function. GHK-Cu applied to thigh skin for 12 weeks improved collagen production in 70% of women treated — compared to 50% treated with vitamin C cream and 40% with retinoic acid. Gene profiling studies were reported to show GHK-Cu affects a large number of genes related to tissue remodelling, antioxidant defence, anti-inflammatory activity, blood vessel growth, and nerve outgrowth. Naturally occurring plasma levels of GHK were confirmed to decline from approximately 200 μg/L at age 20–25 to 80 μg/L by age 60–80, coinciding with reduced regenerative capacity.

Reference: Pickart L et al. (2018). Regenerative and Protective Actions of the GHK-Cu Peptide in the Light of the New Gene Data. International Journal of Molecular Sciences. PMC Article PMC6073405.

Skin Repair Pathways — MMP/TIMP, Collagen & Elastin (PMC, 2015)

A focused review of GHK as a modulator of multiple skin regeneration pathways published in PMC confirmed that GHK-Cu stimulates both synthesis and breakdown of collagen and glycosaminoglycans, and modulates the activity of matrix metalloproteinases (MMPs) and their inhibitors (TIMPs). GHK-Cu at 0.01, 1, and 100 nM incubated with human adult dermal fibroblasts was found to increase production of both collagen and elastin. The review further documented that GHK-Cu attracts immune and endothelial cells to sites of injury, restores replicative vitality to fibroblasts following radiation damage, and stimulates epidermal basal cells to increase integrin and p63 expression — markers of cellular stemness. In cosmetic product studies, GHK-Cu was found to tighten loose skin, improve elasticity, density, and firmness, and reduce fine lines, wrinkles, photodamage, and hyperpigmentation.

Tripeptide Wound Healing & ECM Remodelling Review (Med Sci, 2025)

A comprehensive 2025 review of tripeptides in wound healing and skin regeneration confirmed GHK-Cu as the most studied tripeptide in the context of wound repair and scar minimisation. The review documented GHK-Cu’s ability to promote balanced collagen synthesis, accelerate epithelialisation, and reduce fibrosis in both in vitro and pre-clinical models. The review also noted that GHK-Cu’s copper complexation ability raises Cu2+ penetration rates across the stratum corneum, and documented the development of formulation innovations — including the TriHex peptide system — that combine GHK-Cu-type tripeptides with hexapeptides to produce synergistic upregulation of regenerative genes and suppression of aberrant collagen deposition.
