Frequently asked questions

Quick answers about accounts, pricing, COAs, and orders.

Do I need an account to view products?

No. Products, categories, specifications, and published COAs can be reviewed before sign-in.

Do I need an account to see prices?

No. Prices are shown once you confirm research use. An account — email, a six-digit code, and your researcher type — is required to order.

Are COAs public?

Yes. Published current and historical certificates of analysis are public and remain available for product review.

What is the research-use policy?

Peptrix products are for research use only and are not offered for human consumption.

How do I check my order status?

Sign in and open your account's Orders page to see each order's status and any tracking details.

Who can purchase, and how do I get pricing access?

Purchasing is limited to verified researchers who are 21 or older. After signing in, complete your research profile to unlock pricing and checkout.

What payment methods do you accept?

Checkout accepts major credit and debit cards through our secure, encrypted payment processor. Your card details are handled by the processor and never stored on our site.

How long does shipping take?

Orders are prepared and dispatched promptly, and you'll receive tracking by email once your order ships. See our Shipping page for current processing and delivery details.

How are orders packaged?

Orders ship in discreet, unbranded outer packaging, with temperature-appropriate protection where needed. See our Shipping page for details.

Do you ship internationally?

We currently ship within the United States and a limited set of countries. Buyers are responsible for ensuring compliance with all laws and import requirements at their destination.

How do I read and verify a certificate of analysis (COA)?

Each product's COA lists identity, purity, and batch details. Our COA Explained page walks through what a COA shows and how to verify it independently.

How should I store research materials?

Proper storage depends on the specific material. See our Learn guides for handling and storage of research reference materials.

Something isn't right with my order — what should I do?

Contact our support team and we'll help. Please also review our Shipping and Reship / Replacement policies, which explain how issues with delivery or condition are handled.

What is your refund and return policy?

All sales are final. If an order arrives damaged, incorrect, or lost in transit, we make it right with a reship or replacement rather than a refund — see our Refunds & Reship page for how to report an issue and the claim window.

Do you offer rewards or store credit?

Yes. Signed-in accounts earn loyalty points on eligible orders that can be redeemed toward future purchases, and you can refer other researchers to earn points. Your current balance is shown in your account.

Can I redeem a gift card?

Yes. If you have a Peptrix gift card, enter the code at checkout and its balance is applied to your order. Any remaining balance stays on the card for next time.

How do I match a COA to the product I received?

COAs are published per batch. Match the batch or lot number on your product to the corresponding certificate on the product's COA section, or use our COA Explained page to verify identity and purity independently.
