Frequently Asked Questions

What purity level do your peptides achieve?expand_more
Each product is manufactured to a high-purity specification and verified by HPLC. A Certificate of Analysis with HPLC data is available on request.
How can I verify my batch purity?expand_more
Each unit includes a batch number. Contact our team with your batch number to receive the available Certificate of Analysis for that batch.
How should I store the peptides?expand_more
Lyophilized samples: store at -20°C in a dry, dark environment. Once opened for laboratory analysis, keep the working sample at 2-8°C and complete all assays within 30 days. Minimize thermal cycling to preserve sample integrity.
What countries do you ship to?expand_more
Tracked international delivery, typically 3-7 business days. All shipments include customs documentation.
Do you offer volume supply?expand_more
Yes. Contact us for volume availability.
What payment methods do you accept?expand_more
Visa, Mastercard, AMEX, bank wire. 256-bit SSL encryption.
Can I request a custom peptide blend?expand_more
Yes. Contact our team with specifications for a feasibility assessment within 48 hours. Custom synthesis: 14-21 business days.
