| Attribute | Vesugen | 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 | Vesugen's proposed mechanism follows the three-stage Khavinson short-peptide framework. At the pharmacokinetic level, oral dosing is claimed to produce sufficient intact peptide absorption to deliver bioactive quantities to target tissues. Mechanistic work… | 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 | Not established in humans. As a short tripeptide, KED is expected to be rapidly hydrolyzed in plasma, with an anticipated half-life on the order of minutes; no formal pharmacokinetic study of Vesugen has been published. | ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study) |
| Typical Dose Range | 20 mg oral capsule 1-2 daily for 10-day cycles (60-90 day washout) | 200-500 mcg SC daily (community/RUO; no clinically established injectable dose) |
| Dosing Frequency | 1-2 capsules daily during the 10-day cycle | Once daily subcutaneous; some run 5 days on / 2 days off. Topical: 1-2x daily to cleansed skin. |
| Administration | — | Subcutaneous, Topical |
| Side Effects | Published Khavinson-group observations describe Vesugen as well tolerated at the recommended oral dose of 1 to 2 capsules daily during a 10-day cycle. Specific adverse events noted include occasional mild gastrointestinal discomfort (nausea, loose stools)… | 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 | 390.39 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 Vesugen and GHK-Cu?
Vesugen is a recovery that vesugen's proposed mechanism follows the three-stage khavinson short-peptide framework. at the pharmacokinetic level, oral dosing is claimed to produce sufficient intact peptide…. 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 (Not established in humans. As a short tripeptide, KED is expected to be rapidly hydrolyzed in plasma, with an anticipated half-life on the order of minutes; no formal pharmacokinetic study of Vesugen has been published. vs ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study)), and typical dose range.
Which has the longer half-life, Vesugen or GHK-Cu?
Vesugen has a half-life of Not established in humans. As a short tripeptide, KED is expected to be rapidly hydrolyzed in plasma, with an anticipated half-life on the order of minutes; no formal pharmacokinetic study of Vesugen has been published.. 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.
