The GHK-Cu/KPV blend pairs GHK-Cu's documented effects on collagen synthesis and skin regeneration (Pickart and Margolina 2018) with KPV's anti-inflammatory and gut-healing mechanism. The combination targets skin and tissue repair through complementary pathways — GHK-Cu drives copper-mediated extracellular matrix remodeling while KPV downregulates inflammatory cytokines (NF-κB, TNF-α).
Research-context information only. GHK-Cu and KPV are research peptides not approved by the FDA for injectable use. Protocols, doses, and reactions reported below come from published research and self-reported community sources. This article reports what has been documented, not what should be done. Consult a licensed physician for personal medical decisions.
The buying problem is per-component COA verification, especially copper-binding on the GHK-Cu fraction (selling free GHK without copper is the most common substitution).
This guide covers documented per-mg pricing, COA verification, vial size selection, and red flags. For dosing context, see the GHK-Cu/KPV stack guide.
The blend ships as a single lyophilized 60mg vial (50mg GHK-Cu + 10mg KPV is the standard ratio). Some boutique vendors offer 30mg variants (25mg + 5mg).

The pattern: 60mg blends are the most-cited size. Per-total-mg cost is dominated by GHK-Cu (which is cheaper per mg than KPV individually), so the apparent low blend cost reflects the GHK-Cu-heavy ratio.
Cheapest single-vial option: Ion Peptide's 15% off drops the 60mg vial to $50.15 ($0.84/mg effective) — the lowest effective price we track for buying one vial. Get the code →

Frequently Asked Questions
Is GHK-Cu/KPV blend legal to buy?
Both peptides are sold as research chemicals labeled 'not for human consumption.' GHK-Cu is permitted in cosmetic topical products but the injectable form is research-grade only. KPV is not FDA-approved for any indication. Purchasing research peptides is legal in most US jurisdictions.
How much does GHK-Cu/KPV blend cost per cycle?
A 60mg blend vial (typically 50mg GHK-Cu + 10mg KPV) runs $80-160. At standard community protocols of 1-2mg GHK-Cu + 250mcg KPV daily, one vial covers 4-6 weeks. A 12-week cycle uses 2-3 vials, totaling $160-480.
Is the blend cheaper than buying GHK-Cu and KPV separately?
Modestly yes. 50mg GHK-Cu (~$70-110) + 10mg KPV (~$45-65) separately runs $115-175. A 60mg blend runs $80-160 — roughly 15-30% cheaper, plus the convenience of single reconstitution.
What's the ratio in the blend?
Most vendors ship 50mg GHK-Cu + 10mg KPV (5:1) as the standard ratio. The dominant component is GHK-Cu by mass, but KPV is bioactive at much lower doses (250mcg-500mcg) so the ratios reflect typical use patterns rather than equal-mass mixing.
What purity should I look for in a GHK-Cu/KPV blend?
Per-component HPLC at 98%+ purity for both peptides individually. Mass spec must confirm GHK-Cu (~403 Da peptide + Cu) and KPV (358.43 Da). Copper-binding verification on the GHK-Cu fraction is critical — selling free GHK as GHK-Cu is the most common substitution.
Can I buy GHK-Cu/KPV from a compounding pharmacy?
Limited. KPV is on the FDA's restricted compounding list. Some specialty pharmacies have offered GHK-Cu in topical formulations but injectable forms are restricted. Research vendors are the documented option for research-context buyers.
