GHK-Cu / KPV blend
A supplier blend of GHK-Cu and KPV in one vial, sold for skin and gut repair.
Regulatory status: Not a medicine. Neither component is approved for this use and the pairing is unstudied.
Default vial
60 mg
Default mix
3 mL
Reported range
Varies with the blend ratio
Draw (U-100)
2.5 u
Two compounds in one vial, both with their own entries. Ratios vary by supplier — check the COA.
Where these numbers come from
No human dosing trial defines a dose for this compound. The numbers here are the values community calculators pre-fill — reference only. Neither component has a human dosing trial, and the ratio varies by supplier.

What it is
- Two compounds in a single vial: GHK-Cu and KPV, each with its own Pep-Tidy entry.
- The ratio is the supplier's choice; check the certificate of analysis for the mg of each.
- GHK-Cu is a copper-binding tripeptide; KPV is a tripeptide fragment of alpha-MSH.
- Investigational components only.
How it is described to act
- 1
Given as one subcutaneous injection containing both.
- 2
Each component behaves as it does alone.
- 3
The marketing rationale pairs a connective-tissue peptide with an anti-inflammatory one; no study tests the pairing.
- 4
No outcome has been measured for the combination.
What the research has looked at
What the research covers
- The published work studies GHK-Cu and KPV separately, in animal and cell models. See their individual entries.
- No published study tests the two together.
Strength of evidence: Preclinical evidence only
No study tests this combination; the components have preclinical research only.
What is published comes from cell and animal studies. Findings in those models frequently do not carry over to people.
Reported cautions and unknowns
- A blend is several compounds at once, so an adverse effect cannot be traced to any one of them. Running components separately first is the only way to know which does what.
- Ratios are set by the supplier, not by any standard, so two vials with the same name can contain quite different amounts.
- The safety of the combination has not been studied. What is known, where anything is known, applies to each compound on its own.
- There are no combined pharmacokinetic or toxicity data for any of these blends, so interaction risk is unquantified.
- The FDA's 2026 compounding-committee briefing on BPC-157 documented adverse-event reports and gaps in impurity characterisation for that single peptide.
- Sterility, identity and concentration of multi-peptide compounded vials vary by supplier; only a current third-party Certificate of Analysis can confirm what a vial actually contains.
References
There are none. A search of the published literature returns no studies of this compound — no human trials, no animal work, no cell studies. Anything claimed about it elsewhere is not drawn from published research on this molecule.
Handling this vial
- Lyophilized vials are generally stored at 2–8 °C and kept out of light; once reconstituted with bacteriostatic water they are refrigerated and commonly discarded after 28 days.
- Mix by aiming water down the vial wall and rolling gently — do not shake — and never re-freeze a reconstituted vial.
- Pep-Tidy cannot verify what is in your vial. Ask your supplier for a current Certificate of Analysis (HPLC/MS).
GHK-Cu / KPV blend questions people ask
How do you reconstitute GHK-Cu / KPV blend?
A common starting point for a 60 mg vial of GHK-Cu / KPV blend is 3 mL of bacteriostatic water, which gives 20 mg per mL. Aim the water down the inside wall of the vial, let it dissolve on its own, and roll gently instead of shaking. Pep-Tidy's reconstitution calculator will recalculate the numbers for any other vial size or water volume you use.
How many units of GHK-Cu / KPV blend is one dose?
At 20 mg per mL, that works out to about 2.5 units on a U-100 insulin syringe for a 500 mcg dose. Change the vial size, water volume, or target dose in the calculator and the syringe reading updates with it. This is arithmetic, not a dosing recommendation.
What dosing schedule is reported for GHK-Cu / KPV blend?
Published and community sources describe Varies with the blend ratio, subcutaneous, every day, typically run 4 weeks on and 2 weeks off. These figures describe what has been reported, not what anyone should take — talk to a licensed clinician first.
How should GHK-Cu / KPV blend be stored?
Lyophilized GHK-Cu / KPV blend vials are generally kept at 2–8 °C and out of light. Once reconstituted with bacteriostatic water they are refrigerated and commonly discarded after about 28 days. Never re-freeze a reconstituted vial and never shake it.
