AHK-Cu

Thicker, fuller hair from the copper peptide that wakes up follicles.

  • Aimed straight at thinning hair, wakes the dermal papilla cells that grow the shaft
  • Builds VEGF-driven blood supply around the follicle, the fuel line for new hair
  • Freshness at a glance: bright blue means active, faded or brown means spent

Why researchers choose it

AHK-Cu is a copper peptide, a close cousin of GHK-Cu but pointed specifically at hair. Research describes it waking up the follicle's dermal papilla cells and building the blood supply around each follicle. On its own the regrowth evidence is modest, and the guide frames it as a helper rather than a standalone fix.

Reconstitution reference concentration only, not dosing

Set the vial strength and how much bacteriostatic water you draw into it. This returns the resulting concentration for lab handling. It is a dilution reference, not a dosing recommendation.

Most compounds reconstitute with bacteriostatic water; a few acid-loving peptides use acetic acid instead. How much to draw, and how many vials a cycle needs, live in the Complete Peptide Guide, not here.

How much, and how many vials for a full cycle?

Protocol and cycle-length questions get answered in the Complete Peptide Guide, not here. These listings carry no dosing.
