Yes. Orders placed before 6 PM ET, Monday through Saturday, ship the same day. Orders placed after the cutoff or on a Sunday ship the next shipping day.

Standard shipping is $9.99, and free on orders over $150. 2-Day Shipping is $24.99, and free on orders over $250. Codex Plus and Codex Pro members get 2-Day on every order, and Codex Core members get standard delivery on every order, no minimum.

Every order ships tracked. Your tracking number is emailed to you the moment your order leaves us, so you can follow it the whole way to your lab.

Once a package is handed to the carrier, delivery times rest with them. Standard domestic arrival typically runs 2–5 business days after dispatch.

Carrier delays caused by weather, holidays or events outside our control are not grounds for a refund of shipping, but we will always help you chase a delayed parcel. Email us with your order number and we will look into it.

Every order ships in plain, unbranded outer packaging with no reference to the contents — insulated mailers with ice packs, sealed and discreet. Signature on delivery is not required unless we tell you otherwise.

USPS, UPS and FedEx. The fastest available service is selected at checkout.

We accept Zelle, Venmo, Cash App, and crypto (Bitcoin and USDC). Payment details are provided at checkout. If you have any trouble paying, reach out and we will walk you through it.

The site runs over an encrypted connection and we do not store your payment credentials on our servers. Payments are handled through the provider you choose at checkout.

Yes, at any time before it is dispatched. Email us with your order number and, if it has not yet been handed to the carrier, we will cancel it and refund you in full. Once a parcel has been dispatched it can no longer be cancelled.

Because these are laboratory research materials, not consumer products. Before you can place an order you confirm that you are 21 or older and that the materials are for laboratory research use only — not for human or veterinary consumption. That confirmation is recorded with your order.

No, you can check out as a guest. Creating an account applies 30% off your first purchase automatically and keeps your COAs, order history and tracking in one place.

Yes. Reach out through our contact form or email us directly with what you need and we will get you taken care of.

Research peptides and related laboratory materials, supplied as lyophilised powder in sealed vials, plus bacteriostatic water and multi-vial research kits. Everything is sold strictly as a laboratory research material.

Yes. Every batch is independently tested by a third-party laboratory and the certificate of analysis for that batch is published on the site before it ships.

We publish the measured purity for every batch and our standard is 99%+ by HPLC. The exact figure for the batch you receive is on its COA.

Sealed vials are stored cold and shipped in insulated mailers with ice packs. Brief room-temperature exposure in transit does not compromise integrity. After reconstitution, store at 2–8 °C protected from light.

It is a standard laboratory reagent used to reconstitute lyophilised material. It is stocked as a lab essential rather than as a research compound.

Yes. Blends combine more than one compound in a single vial, and kits group several vials together. Each is listed with its own contents and per-batch COA.

A Certificate of Analysis is the third-party laboratory report for a specific production batch. It records what the material is, how pure it measured, and the tests it passed.

All certificates are listed on our COA page, organised by compound and batch. Every product page also links directly to the certificate for the batch in stock.

Identity verification and purity analysis by HPLC, plus sterility, endotoxin and a contaminant screen. Each result appears on the batch certificate.

An independent third-party laboratory, named on each certificate. We do not test our own material in house.

Every batch, every time. A batch does not ship until its certificate is complete and published.

All sales are final. These are temperature-sensitive research materials and once they leave our cold-chain we cannot verify how they have been stored or handled, so we cannot accept returns of opened or shipped product.

If you receive a damaged vial, the wrong item, or an order that never arrives, that is on us. Report it within 7 days of delivery with your order number and photos, and we will make it right with a replacement or refund.

Approved refunds are issued within 5–7 business days. Card payments return to the card used; how quickly it appears on your statement depends on your bank.

Refunds go back the way the money came. Orders paid in Bitcoin are refunded in Bitcoin, sent to a wallet address you provide, at the US dollar value of the order at the time it was placed — a Bitcoin payment cannot be reversed, so we can only refund it as a new transaction.

Bundle and kit orders are refunded as a whole, because bundle pricing depends on the number of vials in it. Membership plans can be cancelled at any time, which stops future billing and leaves your benefits running to the end of the term you have paid for; a term already begun is not refundable.

All products are intended strictly for laboratory and research use. They are not drugs, supplements, food or cosmetics, and they are not intended to diagnose, treat, cure or prevent any disease.

No. Nothing we sell is FDA approved, and nothing we sell is for human or veterinary use. That statement appears on every product page and in our Research Use Policy.

No. These materials are supplied for laboratory research only and must not be consumed or administered to humans or animals. If that is what you are looking for, we are not the right supplier.

No. We publish what a compound is, what it was tested for, and how to store and handle it as a reagent. We do not publish dosing, administration or protocol guidance of any kind, and we cannot provide it if asked.

Because making them would be both misleading and unlawful for research materials. Our product copy describes mechanism and research context only — it never describes an outcome in a person.

Buyers must be 21 or older and must confirm at checkout that the materials are for laboratory research use only. We do not sell to anyone who tells us they intend personal use.

The Research Use Policy sets out the research-use position in full, and the Terms and Conditions, Shipping Policy, Return & Refund Policy and Privacy Policy are all linked in the footer.
