Response time

Email is read on working days (China Standard Time). Expect a reply within three working days; corrections that affect a published figure are prioritized.

<div class="lot-request"> <h2>Need the batch documents for a specific Pepti lot?</h2> <p>This site does not sell anything, but if a worked example points you at a Pepti lot record and you need the underlying files (COA PDF, HPLC and MS reports) for your own review, Pepti's supply desk handles that. The public library at <a href="https://peptioem.com/coa">peptioem.com/coa</a> is the first stop; for files not shown there, message Pepti Supply on <a href="/whatsapp" rel="nofollow">WhatsApp</a> or email <a href="mailto:contact@peptioem.com?subject=Batch%20documents">contact@peptioem.com</a> with the lot code.</p> </div>
