Copper tripeptide analog used topically for hair growth and skin regeneration.
TL;DR — AHK-Cu is a recovery & repair peptide with a typical starting dose of 50 mg. For a 100 mg vial, add 2 mL bacteriostatic water to yield 50 mg/mL.
Add 2 mL of bacteriostatic water to a 100 mg vial, injecting slowly down the inside wall. Swirl gently; never shake. This yields a concentration of 50 mg/mL.
What is the recommended dose of AHK-Cu?
A typical research dose is 50 mg. Consult the ASCEND calculator for your specific vial concentration and draw volume.
How many doses are in a AHK-Cu vial?
A 100 mg vial reconstituted with 2 mL BAC water yields approximately 2 doses at 50 mg each.
Peptide Intelligence
How does AHK-Cu differ from GHK-Cu?
AHK-Cu (Ala-His-Lys-Cu) is a copper tripeptide analog used primarily for hair loss research. While GHK-Cu has broader tissue remodeling effects, AHK-Cu shows specificity for follicular stimulation and scalp angiogenesis in topical research models.
What is the primary research application for AHK-Cu?
AHK-Cu is researched primarily as a hair growth stimulant. Studies suggest it promotes follicular cell proliferation, inhibits DHT-induced damage, and improves scalp microcirculation when applied topically or injected intradermally.
What concentration is AHK-Cu typically used at?
Topical formulations typically use 0.05–0.5% concentrations. Intradermal mesotherapy protocols use lower concentrations with microneedling. Subcutaneous protocols follow similar dosing to GHK-Cu, typically 1–2 mg per dose.
