The protocol at a glance
There is no human dose. In the lab, AHK-Cu made human hair follicles grow longer at very low concentrations.
| Item | What is known |
|---|---|
| Human dose | Not established |
| Studied in | Human hair follicles and hair-papilla cells in dishes |
| Concentration in the lab study | 1 picomolar to 1 nanomolar (10^-12 to 10^-9 mol/L) |
| Registered study (NCT07888595) | Water-based serum with small peptides, including AHK-Cu, on marked skin sites; amount not stated; enrolling by invitation |
Pyo HK et al. 2007 (Arch Pharm Res). NCT07888595 is an early phase 1 aging-clock study (48 planned) with a mixed peptide serum; it is not an AHK-Cu trial on its own.
We did not capture a community dose. It is described as a cosmetic skin and hair ingredient.
What people say they do, collected from community discussions. Not tested in a trial; shown so you can compare it with the evidence above.
Mixing
No mixing table here: this one is used as a capsule, nasal spray or skin product, or has no human amount to calculate from. The general mixing calculator works for any vial.
What the trials found
No human results exist. One 2007 lab study:
Pyo HK et al. Arch Pharm Res 2007 (PMID 17703734), human hair follicles ex vivo and cultured dermal papilla cells.
Side effects
- There is no human safety data for AHK-Cu on its own.
How it works
Hair-papilla cell support (lab data)
In dishes, AHK-Cu boosted the growth of hair-papilla cells and reduced signs of cell death in them.
