Third Party Lab Tested
Every lot is independently HPLC-tested by Janoshik Analytical, Europe's reference laboratory for peptide purity assessment. The COA shipped with your order is theirs, not ours.
Storage & Handling
Lyophilized peptides should be stored below 16°C, protected from light and moisture, for up to 24 months. Once reconstituted, refrigerate and use within 30 days for protocol consistency.
Reconstitution
Reconstitute with bacteriostatic water using the volumes below. Add solvent slowly along the inside wall of the vial. Swirl gently, never shake, until fully dissolved.

tripeptide.
GHK-Cu is a naturally occurring copper-binding tripeptide (Gly-His-Lys) with a 40-year research literature. Its defining property is the copper ion: bound at the histidine site, copper drives gene-expression changes in dermal models that the bare peptide cannot reproduce.
It remains the most-cited research compound in dermal-remodeling studies - a reference point against which newer skin-research peptides are routinely benchmarked.

GHK-Cu is the most-cited copper-binding peptide in dermal research. Its literature dates to early-1980s skin-remodeling studies and continues to expand across collagen synthesis, glycosaminoglycan production, and matrix metalloproteinase regulation.

Bound Cu²⁺ at the histidine site is the active variable. Bare GHK without copper produces a categorically different transcriptional signature in dermal research models.

Ordered GHK-CU for a research-protocol pilot. Arrived in 4 days temperature-controlled, vials sealed and properly lyophilized. Reconstituted cleanly in BWI with no haze. Will reorder.
