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…

| Category | Skin & Hair | Skin & Hair |
| Research Stage | Phase 4 | Preclinical |
| Mechanism of Action | PDRN exerts effects through two primary mechanisms: (1) Adenosine A2A receptor agonism — PDRN is hydrolyzed to deoxyadenosine fragments that activate A2A receptors on fibroblasts, endothelial cells, and macrophages. A2A activation stimulates VEGF production… | 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… |

| Molecular Weight | No single value - PDRN is a heterogeneous mixture of deoxyribonucleotide polymers (chain lengths ~50-2000 bp, roughly 50-1500 kDa) rather than one defined molecule [PMID:19860658]. | 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). |

- Disguised Alpha
PDRN: potential benefits
- Wound healing acceleration - enhanced angiogenesis, fibroblast proliferation, and collagen synthesis
- Diabetic foot ulcer healing - supported by a randomized, double-blind, placebo-controlled trial (complete healing 37.3% vs 18.9% for placebo) [PMID:24483158]
- Skin rejuvenation - clinical studies suggest improved texture and elasticity, though a 2024 systematic review found the aesthetic evidence base inconsistent [PMID:39198280]
- Hair loss - preliminary evidence only; a small uncontrolled study in female pattern hair loss reported improved hair count and thickness (not established for androgenetic alopecia) [PMID:25524027]
- Anti-inflammatory tissue remodeling - reduction of pro-inflammatory cytokines via adenosine A2A receptor signaling
- Aesthetic skin treatments - widely used in South Korean and European clinical practice
AHK-Cu: potential benefits
- Hair follicle stimulation — activates anagen phase via Wnt/β-catenin in dermal papilla cells
- Reduction of follicle miniaturization in androgenetic alopecia models
- Enhanced scalp vascularity via VEGF upregulation
- Wound healing acceleration — copper cofactor for lysyl oxidase and collagen maturation
- Synergistic with GHK-Cu in multi-peptide scalp formulations
Frequently asked
What's the difference between PDRN and AHK-Cu?
PDRN is a skin & hair that pdrn exerts effects through two primary mechanisms: (1) adenosine a2a receptor agonism — pdrn is hydrolyzed to deoxyadenosine fragments that activate a2a receptors on fibroblasts,…. AHK-Cu is a skin & hair that ahk-cu delivers bioavailable copper ions to follicular and dermal tissues. copper acts as a cofactor for lysyl oxidase (collagen/elastin crosslinking), superoxide dismutase…. The two differ in mechanism, half-life (Short (oligonucleotides degraded rapidly; tissue effects persist longer) vs Unknown (topical half-life, follicular retention not well characterized)), and typical dose range.
Which has the longer half-life, PDRN or AHK-Cu?
PDRN has a half-life of Short (oligonucleotides degraded rapidly; tissue effects persist longer). AHK-Cu has a half-life of Unknown (topical half-life, follicular retention not well characterized). Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
Which is cheaper, PDRN or AHK-Cu?
Lowest listed price on BodyHackGuide: PDRN from $34.95, AHK-Cu from $44.99. 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 PDRN and AHK-Cu?
Stacking depends on mechanism overlap, safety profile, and goals. PDRN and AHK-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.
