GLOW Blend (BPC-157, TB-500, GHK-Cu)
Also known as: Glow Blend, GLOW, BPC-157, TB-500, GHK-Cu Blend, BPC-157 & TB-500 & GHK-Cu
GLOW is a combination research blend of BPC-157, TB-500 (Thymosin Beta-4), and GHK-Cu studied for tissue repair, recovery, and skin and connective-tissue health. Each component is an unapproved research peptide.

Mechanism of Action
BPC-157 is a stable gastric pentadecapeptide that upregulates VEGFR2 signaling and the nitric-oxide pathway to promote angiogenesis, fibroblast migration, and tendon, ligament, and gut healing. TB-500 is the active fragment region of Thymosin Beta-4, sequestering G-actin and accelerating cell migration, blood-vessel formation, and wound closure while modulating inflammation. GHK-Cu is a copper-binding tripeptide that stimulates collagen, elastin, and glycosaminoglycan synthesis, activates antioxidant and tissue-remodeling genes, and supports dermal and wound matrix repair. Used together the components target overlapping angiogenic, anti-inflammatory, and extracellular-matrix pathways.
- Half-life
- Component-dependent: BPC-157 and GHK-Cu are short (minutes to a few hours), while TB-500 has a longer functional duration (days)
- Administration Routes
- subcutaneous
- Research Status
- Research Chemical
Reported Benefits
- Studied for accelerated soft-tissue, tendon, and ligament repair
- May support faster post-exercise and post-injury recovery in models
- GHK-Cu component promotes collagen and elastin synthesis
- Reported angiogenic and anti-inflammatory activity
- Investigated for skin firmness, wound healing, and connective-tissue quality
- Combines systemic recovery peptides with a dermal-remodeling peptide
Potential Side Effects
- Injection-site redness, irritation, or transient pain (GHK-Cu can sting)
- Headache, fatigue, or lightheadedness reported anecdotally
- Possible nausea or flushing
- Unknown long-term human safety as an unapproved blend
Common Dosing
For research use only and not medical advice: vendor research blends are commonly reconstituted to deliver roughly 250-500 mcg BPC-157, 250-500 mcg TB-500, and 1-2 mg GHK-Cu per subcutaneous administration, typically dosed several times weekly. No validated human dosing exists.
The dosing information above is aggregated from research literature and anecdotal community reports for educational purposes only. It is not a recommendation, prescription, or medical advice. Peptides are sold as research chemicals only and are not intended for human use.
Contraindications
- Active or history of malignancy (angiogenic activity is theoretically undesirable)
- Known copper sensitivity or Wilson's disease (GHK-Cu component)
- Pregnancy or breastfeeding
BPC-157
A synthetic peptide fragment derived from a protein found in gastric juice, studied for its broad tissue-healing and cytoprotective effects. Popular in research for tendon, ligament, muscle, and gut repair.
TB-500
A synthetic version of the active region of Thymosin Beta-4, a naturally occurring peptide that regulates cell migration and tissue repair. Researched for recovery, flexibility, and wound healing.
GHK-Cu
A naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) widely researched for skin regeneration, collagen synthesis, and wound healing. Common in topical cosmetics.
KLOW Blend (BPC-157, TB-500, KPV, GHK-Cu)
KLOW extends the GLOW concept by adding the anti-inflammatory tripeptide KPV to BPC-157, TB-500, and GHK-Cu. It is studied for recovery, gut and tissue healing, and skin quality, and its components are unapproved research peptides.
KPV
KPV is a tripeptide derived from the C-terminus of alpha-MSH that exerts anti-inflammatory effects without pigmentary activity. It is studied for gut inflammation, wound healing, and skin conditions.
