Verification
Every batch is identified by a lot number, and its third-party certificate is listed here by lot. Measured values are shown only when they are real and independently verifiable.
Third-party testing in progress
We are currently having this product independently tested by a third-party laboratory. Its certificate of analysis will be published here as soon as the results are available — please check back soon. For laboratory research use only.
GHK-Cu is the copper-bound form of the tripeptide GHK — three building blocks, glycine, histidine and lysine, holding a single copper atom. It is one of the most recognizable small peptides in the catalog.
We prepare it as a single-lot reference material and send every batch for independent testing, then publish the certificate so the number on the label is one you can check.
The detail worth knowing is that GHK-Cu is often listed with the identity of its copper-free version by mistake — the two are easy to mix up, since one is just the other with copper added. The copper is not incidental; it is part of what this molecule is, and a reference standard should record the copper form rather than default to the peptide alone.

GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, a copper-peptide coordination compound. It is catalogued in melanocortin and dermal research within the matrix-signaling peptide class.

Peptide
A short synthetic peptide corresponding to a tail-end fragment of human growth hormone, with one extra building block added at the front.
Peptide
A synthetic peptide of fifteen building blocks (a pentadecapeptide), based on a partial sequence of a protein first identified in gastric juice.
Peptide blend
A blend of two peptides — BPC-157 and TB-500 — supplied together. A mixture, not a single substance, with no identity of its own.
Peptide
A growth-hormone-releasing factor analogue of twenty-nine building blocks, also known as Modified GRF (1-29). Easily confused with the closely related sermorelin.
