How we test
The report for the exact lot we’ll ship you.
Not a generic sample. Every lot is tested by an independent lab, and every vial carries a QR that opens its own lot’s report — so the paper always matches the bottle in your hand.

The share of the vial that is the target peptide versus impurities — separated by HPLC and confirmed by mass spectrometry.
Mass spectrometry confirms it is the exact peptide on the label — right mass, not a look-alike.
Screens for toxic metals (lead, arsenic, cadmium, mercury) left from manufacturing; must stay under safe limits.
Checks for bacterial toxins that can cause fever or immune reactions, measured by the LAL assay.
Confirms no living bacteria or fungi are present — the contents are sterile.
Put us to the test
Check it yourself. We’ll cover half.
Send your vial to a lab you trust — we’ll cover 50% the testing fee. We’re that sure the report matches the vial.
Just email us first — we’ll point you to the same panel the lab ran so the results are comparable, and set up your 50% reimbursement.What this report does and doesn’t cover
- We test a representative sample of each lot, per industry standard — not every single vial.
- Covers purity, identity, heavy metals, endotoxin and sterility — not whether a dose is safe for any use.
- We’re broadening it over time — more tests, and more independent labs.
GHK-Cu (copper tripeptide-1) is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), first isolated from human plasma. The tripeptide binds copper with high affinity, and the complex is widely studied for its roles in wound healing, collagen and glycosaminoglycan synthesis, tissue remodeling and modulation of gene expression. aminobay supplies it lyophilized for laboratory research applications only.
