What does the requested GHK-Cu measurement include?
Clarify whether the question concerns peptide identity, peptide content, the copper-containing material or a separate elemental measurement. Blue colour alone does not answer those analytical questions. The chemical form and calculation basis must be stated for a meaningful content comparison.
Also listed as: Copper peptide GHK; Copper tripeptide-1. Confirm the intended form from the specification.
Information to include
Provide the GHK-Cu specification, labelled amount and sample matrix. Identify cosmetics or other mixtures rather than submitting them as pure powder.
- Raw lyophilized powder is far easier to work with than a finished cream or serum
- For blends, list every expected component and its nominal amount
- Note whether the material is the copper complex or the uncomplexed peptide
Method and reporting scope
Roughly under 1.5 kDa. Runs well on a standard reversed-phase gradient with low-ultraviolet detection, and gives clean, easily read comparisons against reference spectra.
Area purity by HPLC-DAD, identity against reference spectra, verifiable COA. Reference availability and sample suitability are confirmed before acceptance. Read the method and reporting information for the techniques in your quote.
Price, timing and submission
The starting panel is $299 CAD. Volume rates, optional fees and tax are shown separately. Standard peptide analysis typically takes 5-10 business days after receipt and acceptance; other scopes are confirmed in the quote.
Wait for the quantity and mailing instructions before shipping. A report describes the sample tested. Testing one vial does not characterize every unit in a batch.
