Prepare a GLHL (Non-Copper) testing request
Use the full GLHL (Non-Copper) label and supplier specification when describing the sample. The intake code GLHL helps locate this catalogue entry; it does not identify a particular sample or supplier batch.
Also listed as: Uncomplexed GLHL tetrapeptide. Confirm the intended form from the specification.
Information to include
For GLHL (Non-Copper), provide the labelled amount, supplier lot, sample form and any added solvent or excipients. Explain whether you need identity, quantity, impurity information or a comparison with another report.
- 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.
