KLOW
A four-peptide repair blend: GLOW plus the anti-inflammatory KPV.
Overview
KLOW is not a single peptide. It is a premixed vial of BPC-157, TB-500, GHK-Cu and KPV, 80 mg in total. Each part has its own (mostly animal) evidence. No study has ever tested this blend, so any benefit is assumed from the parts.
How it works
Combines four mechanisms: BPC-157 (local repair and blood-vessel growth), TB-500 (cell migration via actin), GHK-Cu (copper delivery and collagen signaling) and KPV (NF-κB inflammation blocking). Whether they add together, or interfere, has not been studied.
Evidence
2/5
No studies of the blend itself. Rated no higher than its weakest core parts (BPC-157, TB-500, KPV are mostly animal data).
Half-life
Mixed: each component differs; all are short-acting signals

Reported benefits
Soft-tissue repair
BPC-157 and TB-500 sped tendon, muscle and wound healing in animals.
Skin and collagen
GHK-Cu has small human studies, but those were topical, not injected.
Inflammation
KPV reduced gut inflammation in mice.
All-in-one convenience
Users like one injection instead of four. Results are self-reported.
“Anecdotal” means reported by users, not shown in controlled trials.
Community-reported regimens
Not recommendations. These are commonly cited ranges, shown so you can see what real-world use looks like.
| Plan | Dose | Frequency | Duration | Route |
|---|---|---|---|---|
| Community standard Dose is of the total blend. If the vial is split 10 mg BPC-157 / 10 mg TB-500 / 50 mg GHK-Cu / 10 mg KPV, 2 mg of blend gives about 250 mcg BPC-157, 250 mcg TB-500, 1.25 mg GHK-Cu and 250 mcg KPV. Check the vial label for the split before dosing. | 2000 mcg | Once daily | 4–6 weeks | Subcutaneous |
| Community cautious start Half dose to see how you tolerate the GHK-Cu sting. | 1000 mcg | Once daily | 1–2 weeks, then reassess | Subcutaneous |

The vial outlasts its ~28-day shelf life once mixed. A smaller vial wastes less.
Math only: concentration (mg/mL) = vial mg ÷ mL of water; units = dose (mg) ÷ concentration × 100. Always double-check against your own vial label and a clinician. This tool does not recommend a dose.
Reconstitution
Diluent: Bacteriostatic water (0.9% benzyl alcohol) — allows multiple draws from one vial.
- Wipe both vial tops with an alcohol swab and let dry.
- Draw the diluent, then inject it slowly down the inside wall of the vial — never straight onto the powder.
- Swirl gently or let it sit; do not shake. Foam can damage peptides.
- Solution should be clear. Cloudy, stringy or discolored = discard.
- This is a blend. The calculator treats the whole 80 mg as one compound, so the dose you enter is total blend, not any single peptide.
- The split between the four peptides matters for dosing. Check the vial label for the split; it is not always published.
- A faint blue tint comes from the GHK-Cu copper and is normal.
- Common mix: 80 mg + 4 mL = 20 mg/mL (2 mg = 10 units).
Storage
Powder
Freezer / fridge
Keep sealed vial in the freezer (−20 °C) for long-term storage; fridge (2–8 °C) is fine for a few weeks. Keep dry and out of light.
After mixing
~28 days
Refrigerate at 2–8 °C. Never freeze after mixing. Keep upright, capped, and out of light.
Travel
Keep cool
Short trips at room temperature are generally fine for powder; keep mixed vials cold.
- Use the shortest stability of the parts as your guide; discard if cloudy.
Side effects & cautions
Reported side effects
- Stinging or burning at injection site (from GHK-Cu)
- Redness or itch at the site
- Head rush or tiredness (reported with TB-500)
- Mild nausea
- Unknown long-term effects
Cautions
- Contains BPC-157 and TB-500, both banned by WADA.
- Several parts promote blood-vessel growth or cell migration. That is a theoretical concern with a cancer history.
- Avoid with Wilson's disease or copper-metabolism disorders (GHK-Cu).
- You cannot adjust one component without changing all four.
FDA & international status
Not FDA-approved
Neither the blend nor any of its injectable parts is an approved drug. GHK-Cu is sold in topical cosmetics, which is a separate thing. Sold online as a research chemical.
Regulations change often — verify with the FDA, EMA, MHRA, Health Canada, TGA and WADA before acting.

FAQ
How is KLOW different from GLOW?
KLOW is GLOW (BPC-157, TB-500, GHK-Cu) plus KPV, an anti-inflammatory fragment. That adds 10 mg to the vial if KPV is 10 mg of it.
Is a blend better than separate vials?
It is more convenient, but you lose control. Separate vials let you dose each peptide on its own schedule. No study compares the two.
Why does it sting?
GHK-Cu is the most likely cause, and it makes up the biggest share of the vial. More diluent or a slower injection can help.
