GHK-Cu
KPV
KPV is a three-amino-acid peptide — Lysine-Proline-Valine — that makes up the C-terminal tail of alpha-MSH (alpha-melanocyte-stimulating hormone). With a molecular weight of only 342.4 Da, it is one of the smallest…

Full KPV profileGHK-Cu
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, a molecule Pickart and Thaler first pulled out of human plasma in 1973. The free peptide (GHK, C14H24N6O4) weighs about 340.4 Da; bind it 1:1…

| Attribute | KPV | GHK-Cu |
|---|---|---|
| Category | Recovery | Skin, Hair & Aesthetics |
| Research Stage | Preclinical | Approved/marketed as a topical cosmetic ingredient (Copper tripeptide-1) with supporting small human studies. Injectable use is preclinical/off-label, research-use-only, with no human clinical trials. |
| Mechanism of Action | KPV's mechanism of action has been worked out in detail over the past 20 years, and it is unusual enough to be worth understanding if you are using this compound. Unlike most peptides, KPV does not primarily act through classical G-protein-coupled receptors on… | GHK-Cu works mostly as a copper shuttle and a signaling peptide. It binds Cu(II) with high affinity (log K around 16.4, close to albumin's 16.2) and can supply or regulate copper for copper-dependent enzymes like SOD1, lysyl oxidase, cytochrome c oxidase, and… |
| Half-Life | ~15–30 minutes (short-lived but downstream anti-inflammatory effects persist) | ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study) |
| Typical Dose Range | 500 mcg-2 mg per dose (standard); up to 5 mg daily in advanced protocols | 200-500 mcg SC daily (community/RUO; no clinically established injectable dose) |
| Dosing Frequency | Once daily subcutaneous or oral | Once daily subcutaneous; some run 5 days on / 2 days off. Topical: 1-2x daily to cleansed skin. |
| Administration | Subcutaneous, Oral, Topical | Subcutaneous, Topical |
| Side Effects | KPV's side effect profile, based on the published literature and the research-peptide community's accumulated experience, is notable primarily for what is NOT reported. Across preclinical studies and the limited human case reports, no serious adverse events… | Topical GHK-Cu is generally well tolerated; higher-concentration formulations (4-5%) raise the odds of irritation, redness, or stinging. Injectable use has no safety data from controlled trials; the main theoretical concern is copper accumulation with repeated… |
| Molecular Weight | 342.43 g/mol | Free peptide (GHK): 340.38 Da (C14H24N6O4). Copper complex (GHK-Cu): 401.9 Da (C14H22CuN6O4, neutral 1:1 Cu(II) complex). |

Frequently asked
What's the difference between KPV and GHK-Cu?
KPV is a recovery that kpv's mechanism of action has been worked out in detail over the past 20 years, and it is unusual enough to be worth understanding if you are using this compound. unlike most…. GHK-Cu is a skin, hair & aesthetics that ghk-cu works mostly as a copper shuttle and a signaling peptide. it binds cu(ii) with high affinity (log k around 16.4, close to albumin's 16.2) and can supply or regulate copper…. The two differ in mechanism, half-life (~15–30 minutes (short-lived but downstream anti-inflammatory effects persist) vs ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study)), and typical dose range.
Which has the longer half-life, KPV or GHK-Cu?
KPV has a half-life of ~15–30 minutes (short-lived but downstream anti-inflammatory effects persist). GHK-Cu has a half-life of ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study). Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
Which is cheaper, KPV or GHK-Cu?
Lowest listed price on BodyHackGuide: KPV from $34.99, GHK-Cu from $34.99. Prices are pulled from the vendor listings tracked on BHG and change frequently. See the compare tables on each compound page for the current set of offers.
Can you stack KPV and GHK-Cu?
Stacking depends on mechanism overlap, safety profile, and goals. KPV and GHK-Cu should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data. Use the BodyHackGuide stack builder for a structured review before combining research compounds.
