02Verify your vial
Every vial label carries a QR code. Point your phone camera at it.
The code opens that lot's certificate with every assay value. No phone? Type the lot from your packing slip on Verify a lot.
Each signed certificate links to the lab's own verification page, so the report can be confirmed independently of us.
03Analytical identity
Studied in collagen-synthesis and extracellular-matrix models in vitro.

Sequence
3-residue chain. The full sequence and its mass-spec confirmation are on each lot certificate.
Every heavy atom is placed from the sequence with ideal bond lengths and angles, so the connectivity is exact. The pose is idealised (an extended chain) and is not a measured conformation. Identity for each lot is confirmed on its certificate.
Structure viewer04In the lab
AHK-Cu is the copper(II) complex of the tripeptide Ala-His-Lys, a close sequence relative of GHK-Cu. In laboratory work it lengthened human hair follicles in organ culture and raised dermal papilla cell proliferation, with a higher Bcl-2/Bax ratio.
Compound
AHK-CuCopper complex of the Ala-His-Lys tripeptideHair follicle organ culture
Endpoint studied
From 10^-12 to 10^-9 M it lengthened isolated human hair follicles and raised dermal papilla cell proliferation.
Pyo 2007 · PMID 17703734Dermal papilla cells
Endpoint studied
At 10^-9 M the Bcl-2/Bax ratio rose and cleaved caspase-3 and PARP fell; the dip in apoptotic cells was not significant.

The current released lot, SA-AHK-2610. Scan the QR code on the vial label to open its certificate. The lot number is also on your packing slip, and the full certificate is here.
Every certificate is issued by an independent laboratory. Each lot has its own public record page with every assay value, and a link to verify the report on the lab's own site once the signed PDF is posted.
Vials are filled slightly over the labelled mass so that every vial meets it. Net content is measured on each lot and published as a number, not a pass.
Email [email protected] within 7 days with your order number and a photo and we will replace it.
Orders by 2 PM ET on a weekday ship the same day, with tracking emailed when the label prints.
