Reference-grade copper peptide research materials such as GHK-Cu and AHK-Cu for in vitro cosmetic and dermatological laboratory research. Documentation-focused sourcing with UAE dispatch.
GHK-Cu is glycyl-L-histidyl-L-lysine complexed with copper(II) — CAS 89030-95-5, molecular weight 403.92 g/mol. VaultLabs catalogues it in two presentation families: fixed-mass lyophilised vials at 50 mg and 100 mg, and sealed raw powder at 1 g and 20 g. AHK-Cu is not a variant of it. Substituting alanine for glycine at the first position gives a different sequence, a different material and its own lot chain, even though the two are frequently referenced side by side in the literature. Registry data, formula and structural detail sit on the GHK-Cu compound monograph.
The blue-green colour of these materials is the copper(II) complex itself and not an added colourant, which makes appearance a genuinely useful receiving check: colour loss, or a shift toward pale grey or brown, is a reason to stop and read the lot record before the container is used. Worth knowing what the paperwork can and cannot settle — HPLC characterises the peptide component, so a high area-percent figure does not by itself confirm that copper stoichiometry is intact. Laboratories that depend on the complex being whole normally plan a confirmatory UV-visible or mass check of their own.
A 100 mg vial is a single sealed unit: one lot, one certificate, one opening event, and a mass someone else has already weighed. A 1 g or 20 g container is bulk intended to be subdivided, so from the moment it is first opened your own weighing and aliquot records become part of the custody chain for everything drawn from it. Certificates never cross presentation families. A vial record does not qualify a raw-powder lot and the reverse is equally untrue, even where compound identity is identical — the batch verification guide explains how to confirm you are reading the record for the container in front of you.
The procurement consequence is concrete. Four active SKUs sit behind the name GHK-Cu, so an order line has to state presentation and unit mass or a stores officer is left choosing. If a laboratory cannot weigh to the tolerance its protocol assumes, or cannot document each subdivision against the parent lot, vials are the correct line regardless of unit price. Bulk powder makes sense when the programme is large enough that repeated vial replenishment introduces more lot variation than in-house subdivision does.
Research in this area is generally cell-culture and matrix-model work — fibroblast cultures, extracellular-matrix marker panels, gene-expression readouts — plus analytical characterisation of the material itself. What those workflows need from a supplier is unglamorous: a stated identity, a lot record that can be cited in a method section, consistent presentation between orders so a repeat experiment is not silently comparing two different materials, and storage conditions printed where the person unpacking the box will read them. VaultLabs describes what the material is and what documents accompany it. We do not describe effects on skin, and nothing here is a consumer cosmetic product — the research-use-only terms apply to every line in this category.
Handling behaviour also differs from ordinary lyophilised sequences. Copper complexes are sensitive to light and moisture, and the stability wording on a label refers to the sealed material as supplied, not to whatever state it is in three weeks after opening. Once the seal is broken the storage history belongs to your records, which is the single most common gap when a result cannot be reproduced later. General expectations for equilibrating, opening and logging containers are set out in laboratory handling basics.
