Copper Peptides in Follicular & Hair Research
GHK-Cu and AHK-Cu are the two compounds that appear consistently in follicular models.
| Compound | Class | Lowest reported study amount | Vial sizes |
|---|---|---|---|
| GHK-Cu | copper-binding tripeptide | 1–2 mg | 50 mg / 100 mg |
| AHK-Cu | copper-binding tripeptide (Ala-His-Lys) | 1–2 mg | 50 mg |
Compound-by-compound notes
GHK-Cu
GHK-Cu is a copper-binding tripeptide studied in extracellular-matrix, skin and hair-follicle research. Standard preparation is 50 mg + 5 mL = 10 mg/mL. Reported arms:
| Study arm | Reported amount | Cadence |
|---|---|---|
| Topical models | 1–2 mg | daily |
| Subcutaneous arms | 1–2 mg | daily |
Product page: GHK-Cu.
AHK-Cu
AHK-Cu is a copper-binding tripeptide (Ala-His-Lys) studied in follicular and dermal research. Standard preparation is 50 mg + 5 mL = 10 mg/mL. Reported arms:
| Study arm | Reported amount | Cadence |
|---|---|---|
| Topical models | 1–2 mg | daily |

How researchers evaluate material before running anything
Purity claims mean nothing without a lot-specific COA showing an HPLC chromatogram, LC-MS identity and endotoxin results. PX1 publishes all three at /coa.
How PX1 documents every lot
Every PX1 lot ships with HPLC purity, LC-MS identity, residual solvent, moisture (Karl Fischer), sterility and endotoxin data. Lot documentation is published at /purity-reports, /endotoxin-reports and /coa. Synthesis, purification, lyophilization and vial fill happen in U.S. facilities — see /manufacturing-process.
