Frequently Asked Questions
Everything you need to know about ordering research-grade peptides from Pure American Peptides.
Who can order from Pure American Peptides?
Anyone 18 or older purchasing for laboratory and research purposes can order. No account is required — you can check out as a guest with just an email address for order updates. Our products are for in-vitro research use only and are not intended for human consumption, medical diagnosis, or treatment.
What is a Certificate of Analysis (COA)?
A Certificate of Analysis is an independent laboratory document that verifies the identity, purity, and quality of a peptide batch. Every COA we publish includes HPLC purity data, mass spectrometry confirmation, batch number, and the name of the independent testing laboratory. We publish all COAs before a product is listed for sale.
How do you ensure peptide purity?
Every batch is synthesized in certified US laboratories using Fmoc solid-phase peptide synthesis, then purified via reverse-phase HPLC to achieve our 99%+ purity threshold. Each batch is independently tested by a third-party analytical laboratory before release. No batch ships below 99% purity.
What are your shipping policies?
All orders are processed within 24 hours and ship with temperature-controlled packaging to preserve peptide integrity. We offer free shipping on orders over $200. Real-time tracking is provided for every shipment. For full details, visit our Shipping & Returns page.
Do you offer volume pricing?
Pricing is per vial at the price shown on each product page. For large or recurring orders, contact our team at info@pureamericanpeptides.com and we'll help with availability and logistics.
How do I check my order status?
Your order confirmation email includes a link to your order status page, where you can see payment status, tracking, and delivery updates — no account needed, just the email you used at checkout. If you created an account, all your orders are also available under Account → Orders.
