Answers to the questions we hear most. If you need anything further, our team is glad to help.

General

What is Aeterna Peptides?

We supply high-purity research peptides, each independently tested and documented, for laboratory and research use.

Are your products for human use?

No. Everything we sell is strictly for laboratory research use only. Our products are not drugs, supplements, or foods, and are not intended for human or animal consumption.

How do you ensure purity?

Every batch is independently analyzed by a third-party laboratory and released only when it exceeds our purity threshold. The certificate of analysis for each batch is available to download.

Orders & Shipping

How much is shipping?

Shipping is complimentary on orders over $250. Standard rates apply below that threshold and are shown at checkout.

Where do you ship?

We ship to eligible destinations shown at checkout. Researchers are responsible for confirming that a compound may be received in their jurisdiction.

How are products packaged?

Compounds ship lyophilized and sealed, packaged to protect integrity in transit.

When will my order arrive?

Orders are processed promptly; estimated transit times appear at checkout and in your confirmation email.

Products & Documentation

Where do I find the certificate of analysis?

On each product page and in the Certificates of Analysis archive. They are also linked from your order confirmation.

How should products be stored?

Follow the storage guidance on the product page. As a general rule, keep vials sealed, cool, and away from light.

Account, Partner & Returns

Do I need an account to order?

An account is required to check out — guest checkout is not available. Creating one only takes a moment and lets you track orders, download certificates, and access membership pricing.

What does Partner include?

Partners earn a commission on all sales, their customers receive twenty percent off their first order, then ten percent off on all recurring orders, and partners continue to earn commissions on every sale their customers make.

What is your return policy?

Because of the nature of research materials, returns are limited. See Returns & Refunds for the full policy and how we handle issues with an order.

Can I become a Partner?

Yes — visit the Partner page to apply.
