Full Pygeum 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 | Pygeum | GHK-Cu |
|---|---|---|
| Category | Herbal | 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 | Pygeum's proposed mechanisms of action span anti-inflammatory, anti-androgenic, anti-proliferative, and bladder-protective effects, with the strongest mechanistic evidence for 5-lipoxygenase/leukotriene pathway inhibition and modest anti-growth-factor effects… | 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 | — | ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study) |
| Typical Dose Range | — | 200-500 mcg SC daily (community/RUO; no clinically established injectable dose) |
| Dosing Frequency | — | Once daily subcutaneous; some run 5 days on / 2 days off. Topical: 1-2x daily to cleansed skin. |
| Administration | — | Subcutaneous, Topical |
| Side Effects | Pygeum's side effect profile is generally mild and comparable to placebo in clinical trials — one of the more favorable tolerability profiles among BPH interventions, and substantially better than pharmaceutical alternatives (alpha-blockers, 5-ARIs) which… | 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 | — | Free peptide (GHK): 340.38 Da (C14H24N6O4). Copper complex (GHK-Cu): 401.9 Da (C14H22CuN6O4, neutral 1:1 Cu(II) complex). |
| Common Vial Sizes | — | 50 mg, 100 mg |

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 reported vs ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study)), and typical dose range.
Which has the longer half-life, Pygeum or GHK-Cu?
Pygeum has a half-life of not reported. 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.
Can you stack Pygeum and GHK-Cu?
Stacking depends on mechanism overlap, safety profile, and goals. Pygeum 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.
