See a real analytical packet before you commit.

A real, batch-specific Certificate of Analysis from a recent Lyochem release. It identifies the lot and records the analytical tests performed, applicable specifications, and results. Because the appropriate panel varies by molecule and project, ask sales for the COA corresponding to the lot offered or shipped. Sequence-level, microbiological, endotoxin, or expanded stability work can be scoped before quotation when required.

Within 24 business hours of submitting this form, in most cases. The reply comes from a regulatory specialist who selects the appropriate sample lot for your peptide of interest, not from an auto-responder. If you submit outside our working hours (UTC+8), the reply lands at the start of the next business day.

Real, batch-specific. The COA references an actual lot we've released in the last 60-90 days, with lot number, manufacturing date, re-test date, and all measured analytical values present. We don't send marketing templates with placeholder values, that would defeat the purpose of supplier qualification. If a specific lot is more recent than the sample we send, we can substitute it on request.

Not unless you want it to. The regulatory specialist who replies will offer to answer technical questions about the analytical packet and discuss procurement context if relevant, but a sample COA request alone doesn't trigger a sales sequence. If you've opted into the newsletter, you'll receive periodic regulatory briefings (typically once a month) which you can unsubscribe from any time.

We need a business email address to send the COA, so no. We don't ask for a phone number, mailing address, or any other contact detail, just enough to deliver the document and follow up if you have technical questions. The email and the data you provide on this form are handled under our privacy policy and never shared with third parties.
