Check the Lab Data Before You Add to Cart
Every lot we stock goes to an independent laboratory for two tests: HPLC purity, and the milligrams actually in the vial against the amount on the label. Both results are filed in the certificate library under the lot code printed on the vial, so the vial you hold can be matched to its own report.
Across 51 published lots, mean HPLC purity is 99.47%. 43 of those 51 measured 99% or higher; the lowest result on file is 97.646% (Crystagen 20mg), and that certificate is published like the rest. Measured content averages 112.9% of the labelled amount over 51 lots.

Questions US Buyers Ask Before Ordering
Nothing in the catalog is an FDA-approved drug, and none of it is sold as a dietary supplement. Each compound is sold as a laboratory reagent for in vitro research, not for human or veterinary use, and we do not give dosing or administration advice. US legal status explained →
Yes. Most lots measure above 99% HPLC purity, but a small number of compounds come back around 98%, and those certificates go into the library alongside the rest. The purity figure on this page is the average across every published lot, not only the best ones. See every certificate →
Orders ship from US stock by FedEx with tracking and typically arrive in 1–3 business days, depending on the destination. Shipping is free once the order passes $200 USD.
Visa, Mastercard, American Express, Apple Pay and Google Pay, processed on a hosted checkout page and charged in US dollars. Card details are entered on the payment processor’s page, not stored on our site.
Yes. Mix & Match counts every vial in the cart regardless of compound or strength: 5% at 3 vials, 10% at 5 vials and 20% at 10 vials. The discount is worked out automatically at checkout, with no code to enter.

Ordering Research Peptides From a US Supplier
Eppix Labs is a US-based supplier of research peptides for in vitro laboratory work, from GLP-1 and incretin analogues to tissue-repair fragments and growth-hormone secretagogues. Orders are filled from domestic inventory and priced in USD, and every compound’s published lab results are one click from its product page.
Combining compounds still counts toward Mix & Match: 5% at 3 vials, 10% at 5 vials and 20% at 10 vials, applied at checkout. The free Peptide Calculator works through reconstitution volume and concentration for bench prep. Questions go to hello@eppixlabs.com, answered weekdays 9 AM–5 PM MT.
