Pal-AHK
Also known as: Palmitoyl AHK · Palmitoyl-Ala-His-Lys
Grade describes the published research on the molecule. It is not a quality score, a safety score, or a release state.
What this is
Pal-AHK is commonly described as a palmitoylated alanine-histidine-lysine tripeptide. Market pages disagree on the INCI number, C-terminal acid or amide and identifiers. Those differences prevent a single assumed identity.
Evidence position
Grade U is deliberate. Direct research exists for AHK-Cu, and records exist for Pal-GHK, but neither is Pal-AHK. A complete identity record must come before an evidence grade.
What the record does not establish
Structural similarity does not make AHK-Cu, Pal-GHK and Pal-AHK interchangeable. Supplier terminology and purity percentages are not substitutes for an exact sequence, molecular mass and lot-linked analytical record.

LIVE DATABASE INDEX / SEPARATE FROM CURATED EVIDENCE
Records below come directly from public scientific databases. They help find relevant material, but do not affect the evidence grade until they are matched to the molecule and added to the curated source list.
