How we work

Everything published. Nothing just claimed.

Batch-level verification

Every lot is assayed by an independent laboratory before it ships. The certificate is published against the lot number and stays online after the batch sells out.

Questions

Before you order

What does “research use only” mean?

Everything sold here is a chemical reference standard for in-vitro laboratory research. Nothing on this site is for human or veterinary use, and you must be 18 or older to order.

How do I verify a certificate of analysis?

Each vial carries a lot number, and the independent laboratory certificate for that batch is published right on the product page — look for the certificate panel with the purity, the testing lab and a View Certificate button.

How does payment work?

We take Zelle, Cash App and Venmo — no card processors. Checkout shows the payment handle and your order total. Send the payment, mark it sent, and your order moves to processing once it’s confirmed.

How fast do orders ship?

Orders dispatch within one business day of payment confirmation, from stock held in the United States. The tracking number is added to your order automatically when the shipping label is created.

Do prices drop at higher quantities?

Yes. Quantity pricing is set per product and applies automatically in the cart — the tier table on each product page shows exactly where the breaks fall.

How should vials be stored?

Lyophilized peptides should be kept cool, dry and out of direct light; long-term storage guidance for a specific compound is listed on its product page alongside the certificate for its batch.

Tested. Published. Shipped.

41 compounds. Certificates published per lot, quantity pricing applied automatically, dispatch within one business day.
