GHK-Cu Capsules
GHK-Cu (copper tripeptide-1) is a copper peptide: the tripeptide glycyl-L-histidyl-L-lysine (GHK) complexed with copper. Glow Peptides supplies it here as encapsulated powder in a sealed research container, and separately as a lyophilized vial. For laboratory research use only, not for human or veterinary use.

GHK and GHK-Cu chemical references
Free GHK and a copper complex have different formulas and molecular weights. The records below are PubChem references, not an assignment of chemical form to the supplied material.
| Named reference | Formula | Charge | Molecular weight | Source |
|---|---|---|---|---|
| Free GHK (glycyl-L-histidyl-L-lysine) | C14H24N6O4 | 0 | 340.38 g/mol | CID 73587 |
| Prezatide copper | C14H23CuN6O4+ | +1 | 402.92 g/mol | CID 71587328 |
A registry entry does not establish which chemical form a vial or capsule contains. Consult the lot report for its printed identity and analytical scope.
The Bioviridian report for capsule lot 2605-SXH-GH2-01 prints MW (g/mol): 403.2. This is the value printed on that report; it does not identify a PubChem record or establish the form of another lot. See the lot certificate linked on this page.

Frequently asked questions
How will my order ship?
Orders placed before 4 PM ET ship the same day, Monday through Saturday. Everything goes out in discreet, secure packaging, and a tracking number is emailed to you the moment your label is created.
Is a Certificate of Analysis included?
Check the lot documents shown for the selected material and match the report lot number to your label. Documentation may be missing or held for clarification. A document on file does not itself establish independent analytical review, identity, purity, or sterility. Read the specific report for its methods, findings, and limitations; contact us to check availability if your lot is not listed.
Where is it manufactured?
Glow research materials are synthesized by our manufacturing partners in cGMP (current Good Manufacturing Practice) facilities using Fmoc solid-phase peptide synthesis, and each lot is then tested by an independent U.S. laboratory. Manufacturing conditions and analytical results are different things: check the lot-specific report for the methods and findings it records.
How should I store it?
Store at room temperature, away from direct sunlight and moisture. No reconstitution or refrigeration required.
What's your return policy, and what if material doesn't match its Certificate of Analysis (COA)?
You're covered three ways. A money-back quality guarantee: if your material doesn't match its independent U.S. lab COA, we'll replace it or refund you in full within 30 days. Hassle-free returns: unopened, unused items in original sealed condition can come back within 30 days of delivery for a refund. And if a shipment arrives damaged, email us within 48 hours with photos and a free replacement ships once verified. Full policy.
Can I use this for anything other than research?
No. All products are sold strictly as research materials for in-vitro laboratory use only. They are not drugs, supplements, or medical devices, and are not intended for human or veterinary use.
