Why These Three Together
Each compound targets a different phase of the repair cascade. BPC-157 triggers the initial healing response — promoting new blood vessel formation and reducing the inflammatory environment at the injury site. TB-500 drives cell migration, physically moving repair cells from healthy tissue to the damaged area via actin regulation. GHK-Cu then remodels what's been repaired — organising collagen, improving skin quality, and resetting gene expression patterns associated with ageing tissue. The 5:1:1 ratio (GHK-Cu dominant) reflects the community consensus that collagen remodelling requires significantly more copper peptide by weight than the signalling compounds.
Dosing — Blended Vial (80mg total)
Standard reconstitution: 3mL bacteriostatic water per vial. This gives a concentration of approximately 26.7mg/mL total blend.
| Compound | Per Vial | Per 0.1mL Draw | Frequency | Route |
GHK-Cu |
50mg |
~1.67mg |

A 0.10mL draw = ~2.67mg total blend. A standard vial at 3mL provides approximately 30 daily doses. Cycle: 8–12 weeks on, 2–4 weeks off. Rotate injection sites — abdomen, thighs, upper arms.
Blend Vial vs Separate Vials
Blend Vial
Single Draw
One reconstitution, one injection per dose. Simpler protocol, fewer vials to manage. Ratio is fixed at 5:1:1 — cannot adjust individual compounds independently. Best for maintenance or straightforward skin/recovery protocols.
Separate Vials
Individual Dosing
Full control over each compound. Can increase TB-500 for acute injury (loading phase), maintain GHK-Cu daily, and cycle BPC-157 separately. More vials, more prep — but better for injury-specific or phase-based protocols.
Reconstitution
1
Allow vial to reach room temperature before opening. GHK-Cu gives the powder a slight blue tint — this is normal. Draw 3mL bacteriostatic water into a clean syringe.
2
Insert the needle through the rubber stopper. Inject water slowly down the inside of the vial wall — do not blast directly onto the powder. This prevents degradation of the peptide structure.
3
Do not shake. Gently swirl or roll the vial until the powder dissolves completely. The solution should be clear with a very faint blue tint from the copper complex.
4
Store reconstituted vial at 2–8°C (refrigerated). Use within 30 days. Do not freeze the reconstituted solution. Lyophilised (unopened) powder: store at −20°C, stable for 12+ months.
5
Draw 0.10mL (10 units on a U-100 syringe) for a standard dose. Inject subcutaneously at a 45° angle. Rotate sites each injection. Abdomen, thigh, and upper arm are all suitable.
Evidence Grade per Compound

Combined
No RCT on the combination specifically. Rationale extrapolated from individual compound data.
Glow vs Klow — When to Choose Each
Glow (this blend) is the three-peptide foundation — repair, cell migration, collagen remodelling. Best for skin quality, general maintenance, and tissue recovery where inflammation is not the primary obstacle.
Klow adds KPV to Glow. KPV directly blocks NF-kB — a central inflammation switch. Choose Klow when chronic or persistent inflammation is limiting recovery, when gut involvement is present, or when the healing environment needs clearing before repair can accelerate. See the Klow entry →
Common Use Cases in the Community
✦
Skin rejuvenation and anti-ageing maintenance — GHK-Cu dominates at 50mg. Collagen remodelling, improved skin density, reduced fine lines. Often run continuously as a low-dose maintenance protocol.
✦
Post-injury recovery — BPC-157 and TB-500 combination widely reported for tendon, ligament, and muscle recovery. GHK-Cu adds extracellular matrix remodelling to the repair.
✦
General tissue maintenance — Used by the biohacker community as a baseline recovery stack alongside training or after periods of high physical stress.
✦
Hair quality — GHK-Cu has preclinical evidence for hair follicle enlargement. Some community members use the blend primarily for scalp and hair quality. Note: WADA prohibits BPC-157 and TB-500 in competitive athletes.
Safety and Considerations
⚠
WADA prohibited — BPC-157 and TB-500 are both prohibited in competitive sport. GHK-Cu is not currently on the prohibited list. If you are subject to anti-doping rules, do not use this blend.
⚠
No human RCT on the combination — the rationale for combining these compounds is evidence-based but the synergy is extrapolated from individual compound studies and community experience. This is not a clinically validated protocol.
⚠
Copper accumulation risk with long cycles — GHK-Cu at high doses over extended periods. Standard 8–12 week cycles with rest periods are the community norm. Do not run continuously without breaks.
✓
Generally well tolerated — injection site reactions (transient redness, mild itch) are the most commonly reported side effects across all three components. No serious adverse effects in the published individual compound literature.
Blood Work
No specific blood work is required for the Glow blend that isn't already part of a standard annual panel. If running as part of a broader anti-ageing protocol: inflammatory markers (hsCRP, fibrinogen), liver function, and copper/zinc ratio are worth including at baseline and after 12 weeks. No peptides in this blend are expected to affect hormonal panels.
