Survived a customs delay intact
International order held two extra days at customs. Cold-pack was still cold on arrival. Whoever specified the packaging tolerance built in real margin.

About GHK-Cu
GHK-Cu (glycyl-L-histidyl-L-lysine copper(II) complex) is a naturally occurring tripeptide bound to a copper ion. It exists endogenously in human plasma at meaningful concentrations through young adulthood and declines progressively with age. Research spans wound-healing models, extracellular matrix remodeling, fibroblast activity, hair follicle biology, and anti-inflammatory signaling. GHK-Cu is among the most-cited peptides in dermatological and regenerative research, with over four decades of published literature. For research use only. Not for human consumption.

Batch traceability is a real feature
Being able to tie a vial back to a specific batch and a specific COA is more important than most suppliers realize. Pepthera built this in by default.

Exceptional purity — exactly what the COA promised
Ordered for a controlled study. HPLC confirmed 99.2% purity. Lyophilised cake dissolved instantly on reconstitution, no cloudiness. Impressed with cold-chain packaging — still at temp on arrival. Will order regularly.

Premium quality for clinical research
Consistently above spec. The purity reading on the COA was independently confirmed by our lab. Cold-chain handling was excellent — vials arrived perfectly preserved.

Quality control presentation felt premium
Tamper-evident seal, batch number printed on the vial, COA tied to that batch by serial — the level of documentation matches what I'd expect from a regulated supplier, not a research outlet. Asked a storage question by email and got a detailed answer in under 3 hours.

Second order. Same purity, same packaging quality, same fulfillment speed. Predictability matters when planning a research timeline — Pepthera delivers it.
