Do you publish prices?
No. Price depends on sequence, purity target, scale and documentation, so a list price would be misleading. Send the specification and you get a written quotation.
Can I get a sample before ordering?
Yes, for most grades. Sample policy: [PLACEHOLDER: sample size and cost].
How long does a custom sequence take?
It depends on length, modifications and the analytical package. The quotation states a lead time, and [PLACEHOLDER: lead time] is the typical range for a first lot.
Is the COA batch-specific?
Yes. A COA covers one lot number, and that number appears on the drum, the COA and the invoice. Specimen COAs on this site are format examples only.
Can you supply cosmetic and food grades of the same peptide?
Where the chemistry allows, yes — but the specifications differ, and so do the documents. State the end use so the quote reflects the right route.
Need the specification, not the theory?
Ask for the COA, TDS and a quotation.
Tell us the sequence, purity target and volume — the reply includes the documents that will ship with the lot.
