GHK‑Cu
Lyophilized, 50 mg, in a 5 mL vial, sealed.
Presentation
What is in the vial, how much, and how it is sealed.
The color is the complex itself, a copper(II) center held by the peptide, and not an additive.
GHK‑Cu is registered under its full name, glycyl-L-histidyl-L-lysine, copper(II) complex, 1:1, supplied as a sterile lyophilized solid, 50 mg to the vial.
It is filled at 50 mg, sealed, as a blue to blue-violet lyophilized solid. The molecular formula and the average mass are the figures the identity test is run against.
As filled
Standard GB‑16Identity is settled before purity.

The copper is coordinated, not admixed: the entry is a 1:1 complex between the tripeptide and copper(II), which is why the molecular formula on the register carries the metal inside it. It is supplied on the research channel, to verified research institutions, under the research legend.
Identity is confirmed before we open a container. Purity is measured after. A purity result says how much of the lot is one substance; an identity result says which substance that is. A wrong molecule can measure high on purity, which is why the two are never the same test.
Every line has a method and a limit.
A lot that misses a single line is not released.

RESEARCH CHANNEL · INSTITUTIONAL DELIVERY
Material supplied on this channel is labeled for research use only and is not for human or veterinary use. That wording is printed on the vial and the carton. No prescription statement, no pharmacy‑of‑record line. It ships to your institutional address and nowhere else.
Storage is printed on the vial.
The condition on the label, the condition once in use, and the container.
Conditions
As labeledThe storage condition is printed on the vial and on the carton, and the stability summary is the data behind it. The in‑use condition applies from the moment the seal is broken.
Every container is quarantined until we confirm what it is. A supplier’s certificate is a claim, not a result. Nothing leaves quarantine on a claim.
This entry stands on one authority.
It ships to your institutional address, and nowhere else.
This entry is supplied on the research channel, to verified research institutions, against a named principal investigator and an institutional authorization. It ships to your institutional address — never a residence, never a clinic. We supply no protocol and no guidance for its use. Read the rule this entry stands on.
Research channel only (ELIGIBILITY §6): supplied as a research-use-only material to verified research institutions under the research attestation set. The label carries the research legend: the material is labeled for research use only and is not for human or veterinary use. No prescription statement appears; the material ships only to the institutional address on the account and is not offered on the clinical channel.
