Questions

Before you order

All questions
What are these products?
One Source Peptides supplies lyophilized research compounds for scientific, laboratory, and educational research. They are not for human or veterinary use.
Can I get a Certificate of Analysis?
Yes. Certificates of Analysis are available on request. Email info@onesourcepeptides.com or use the Contact form with the product and lot number. Published certificates are in the COA Library.
Who can buy?
Qualified researchers, laboratories, academic institutions, and other organizations doing legitimate laboratory research, age 21 or older. You are responsible for following the laws that apply to you.
How do I pay?
Card and Zelle are the payment methods at checkout. Zelle is 4% off the merchandise total when you pay the One Source Peptides business account. Instructions are shown after the order is placed. This is not a personal Zelle account. A card order is reserved when it is placed, and card payment is completed with you before it ships. Bank transfer is not offered. Contiguous United States shipping is a flat $12.95 on the amount due when fewer than 6 vials ship. Bulk orders of 6 or more vials are charged by weight instead.
