AHK-Cu
AHK-Cu (Ala-His-Lys-Copper) is a copper chelating tripeptide related to but distinct from GHK-Cu (Gly-His-Lys-Copper). Where GHK-Cu is the most-studied copper peptide and naturally occurs in human plasma, AHK-Cu is a…

| Attribute | AHK-Cu | BPC-157 |
|---|---|---|
| Category | Skin & Hair | Injury, Repair & Recovery |
| Research Stage | Preclinical | Preclinical |
| Mechanism of Action | AHK-Cu delivers bioavailable copper ions to follicular and dermal tissues. Copper acts as a cofactor for lysyl oxidase (collagen/elastin crosslinking), superoxide dismutase (antioxidant), and vascular endothelial growth factor (VEGF) signaling. The tripeptide… | Nitric Oxide (NO) System Modulation BPC-157 exerts a central integrative effect through modulation of the nitric oxide system. Studies by Seiwerth et al. (2022) demonstrated that BPC-157 counteracts both NO-excess and NO-deficiency states, functioning as a… |
| Half-Life | Unknown (topical half-life, follicular retention not well characterized) | Short plasma half-life. The first formal preclinical ADME study reported an elimination half-life under ~30 minutes after IV/IM dosing in rats and dogs, with linear dose-proportional kinetics (PMID: 36588717); a 2026 biopharmaceutical review confirms this sub-30-minute plasma half-life and highlights a pharmacokinetic-pharmacodynamic disconnect, as biological effects persist for hours to days (PMID: 42198317). No full human pharmacokinetic study has been published; twice-daily dosing is empirical/community-standard rather than PK-derived. |
| Typical Dose Range | — | 200-500 mcg subcutaneous 1-2x daily (community protocols); 1-10 mcg/kg in animal studies |
| Dosing Frequency | once_daily | Twice daily (AM and PM) for optimal serum levels; once daily acceptable |
| Administration | Topical, Subcutaneous, Intradermal | Subcutaneous, Oral, Intraperitoneal, Intravenous |
| Side Effects | — | Generally well-tolerated. Mild nausea or GI discomfort during initial use. Temporary increase in pain/inflammation at injury site (healing response). Rare: drowsiness, dizziness, mild headache. Very rare: transient changes in blood pressure. |
| Molecular Weight | Free peptide (AHK): 354.41 Da (C15H26N6O4). Copper complex (AHK-Cu): 415.9 Da (C15H24CuN6O4, neutral 1:1 Cu(II) complex - Cu(II) displaces two protons from the tripeptide ligand). | 1419.5 g/mol (average); molecular formula C62H98N16O22 |

Which has the longer half-life, AHK-Cu or BPC-157?
AHK-Cu has a half-life of Unknown (topical half-life, follicular retention not well characterized). BPC-157 has a half-life of Short plasma half-life. The first formal preclinical ADME study reported an elimination half-life under ~30 minutes after IV/IM dosing in rats and dogs, with linear dose-proportional kinetics (PMID: 36588717); a 2026 biopharmaceutical review confirms this sub-30-minute plasma half-life and highlights a pharmacokinetic-pharmacodynamic disconnect, as biological effects persist for hours to days (PMID: 42198317). No full human pharmacokinetic study has been published; twice-daily dosing is empirical/community-standard rather than PK-derived.. Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
