Storage & reconstitution
-
01 — Lyophilized storage
Store lyophilized vials at −20°C (or colder) in a dry, dark environment. Avoid repeated temperature cycling before reconstitution.
-
02 — Reconstitution
Reconstitute with bacteriostatic water (0.9% benzyl alcohol). Introduce the diluent slowly along the vial wall; gently swirl — do not shake vigorously. Typical research volumes: 1–2 mL per vial unless your protocol specifies otherwise.
-
03 — After reconstitution
After reconstitution, refrigerate at 2–8°C. Use within the timeframe defined by your research protocol. Do not freeze reconstituted solutions. Avoid freeze–thaw cycles.
For qualified laboratory research only. Not for human or veterinary use. Follow your institutional SOPs for sterile technique and waste disposal.

FAQ — GHK-Cu
Is this compound intended for human use?
No. It is sold strictly for research under appropriate oversight.
Do you supply certificates of analysis?
Yes — representative CoA and supporting analytical summaries are available for qualified laboratory buyers.
How should I choose a reconstitution solvent?
Base the choice on solubility, buffer compatibility, and stability data for your specific peptide and assay — follow your validated SOP.
GHK-Cu (50 mg) is offered as a research-grade reagent for teams working in Peptides for skin health & tanning. Each batch is intended for documented R&D workflows — stability studies, receptor binding, in vivo models under IACUC, or bioanalytical method validation. We recommend qualifying each lot against your internal acceptance criteria before use in pivotal experiments. For laboratory research only. Not for human consumption, clinical use, or veterinary applications without proper authorization.

Best purity profile I've seen in this category
My go-to shop for peptides – I can always ensure that the product are pure and the efficacy is at the maximum. Their ghk-cu is very potent!

Exceptional purity — exactly what our lab needs
We've been sourcing research peptides for our metabolic studies for several years, and this supplier consistently delivers material that meets our internal QC standards. The HPLC profile matches the CoA perfectly. No batch-to-batch variation that we can detect. Shipping was fast and well-packaged with sufficient cold packs. Will continue ordering for our next study cycle.

Premium grade — no surprises
Working in a regulated research environment means I need suppliers who understand documentation. Every batch from peptides-pro comes with traceable lot numbers, HPLC chromatograms, and MS data. This is exactly the standard our SOP requires. The peptide itself performed flawlessly in our in vitro binding assay. Will be ordering again for phase 2 of our study.

Solid supplier for ongoing research programs
Been using this supplier for approximately 8 months across multiple study phases. The quality has been consistent. I particularly value that I can request CoA data before committing to a larger order — this level of transparency is what separates professional research suppliers. Delivery to Canada was smooth, though we always budget extra time for customs.
