Cosmetic Research Peptides & Compounds
Eclipse Peptides' cosmetic research category features high-purity reference compounds studied in the context of dermal cell models, copper-peptide chemistry, and SNARE-complex research. Each compound — GHK-Cu, AHK-Cu, and SNAP-8 — is supplied as a lyophilized powder at ≥99% purity and characterized by molecular formula, CAS number, and analytical purity. All compounds in this category are third-party tested and ship with a batch-specific Certificate of Analysis. These are supplied as research reagents, not cosmetics or consumer products, and are intended strictly for in-vitro laboratory research and not for human or animal use.
Category FAQ.
Are these products cosmetics?+
No. They are research reagents supplied for in-vitro laboratory investigation. They are not cosmetics, drugs, or consumer products.
What purity are these compounds?+
All compounds in this category are specified at a minimum ≥99% purity and verified by third-party HPLC and mass-spectrometry testing.
Do they ship with documentation?+
Yes. Every batch ships with a batch-specific Certificate of Analysis documenting identity, purity, and quantitative data. Safety Data Sheets are available on request.
How should these compounds be stored?+
Supplied as a lyophilized powder and stored under cold-chain-appropriate conditions (2–8°C) per each product's specification. Consult the Certificate of Analysis for reconstitution and long-term storage guidance.
Why are copper peptides blue?+
The copper(II) complex gives copper-binding tripeptides such as GHK-Cu and AHK-Cu their characteristic blue color in lyophilized form.
