What the label states, the lot delivers — net peptide mass, not gross powder weight, purity reported as measured rather than rounded up, and a Certificate of Analysis for every lot.
Net peptide mass, not powder weight; purity as measured, not rounded up; a COA per lot.

Frequently asked
A real, batch-specific Certificate of Analysis for a recent release of the peptide you're interested in. The COA includes: HPLC chromatogram with peak-integration purity (≥99.0% for most catalog items), ESI mass-spec identity confirmation within 0.5 Da of theoretical molecular weight, water content by Karl Fischer titration, and counter-ion identification (acetate by default). For peptides above 15 amino acids, we also include the LC-MS/MS sequence verification data. Optional add-ons (LAL endotoxin per USP <85>, USP <61>/<62> microbial limits, stability data) are available on request, mention these in the intended-use field.
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.
