FAQ
Everything you need to know
The questions we are asked most, answered from the same policies the rest of the site runs on.
What is AFA Biosciences?
Not for human or veterinary use.
A supplier of synthetic peptides and reagents for in-vitro laboratory research. Every lot is third-party tested before release, and a certificate of analysis and safety data sheet ship with every order.
About us →Are these for human use?
No. Everything here is a chemical reference material for laboratory research only. Placing an order requires certifying that is what you are buying it for.
Research use disclaimer →What purity are your peptides, and who tests them?
99% or better by HPLC, released against third-party testing before a lot is offered. Every certificate is for the specific lot you receive.
Certificates and lot data →How do I check the certificate for what I was sent?
The certificate matches the vial in your hand.
Every container carries a lot number on its label. Enter it in the lot lookup and you get that lot's own results — not a typical result for the product.
Look up a lot →How does your pricing work?
Unit price falls automatically as the quantity goes up — no code and no account needed. A promotion is different: its code has to be entered at checkout. One code per order, and codes do not stack.
Browse the catalog →What payment methods do you accept?
Credit or debit card, Cash App or Zelle, Bank transfer (ACH) and Cryptocurrency. Card details are entered on our processor's own secure form and never reach this site. The checkout shows which methods are available for your order.
Go to checkout →How fast do you ship?
Orders placed by 2 PM Eastern ship the same or next business day. Three tracked services at checkout: Standard (2–5 business days), Two day (2 business days), Overnight (1 business day). Prices are shown at checkout.
Shipping policy →Do you ship outside the United States?
You are the importer of record. Duties, taxes and customs charges are set by your country, are not included in this order, and are payable to the carrier before delivery.
Shipping outside the United States is quoted by hand. Place the order and we will email you the shipping cost and payment details before anything ships — you are not charged until you accept the quote.
International shipping →What is your return and refund policy?
Opened or used vials cannot be returned, except a lot that failed its own test.
Only where the fault is ours or the shipment arrived damaged, with supporting evidence in every case. For a wrong item or transit damage the vial must be unopened and unused. The exception is a lot that tests below the purity on its certificate: testing means opening it, and the report is the evidence. Opened or used material is not otherwise returnable.
Returns and refunds →How do I contact support?
