Start with the quoted variant.
For a BPC-157, GHK-Cu or Retatrutide enquiry, record the exact identity, accepted content basis and presentation first. Add your order reference and proposed quantity. This is the starting point for matching later documents, rather than relying on the peptide name alone.
Ask which lot or lots are proposed for the order and how the supplier’s lot identifiers connect to laboratory sample references. A sample code and a lot number may use different formats; request the documented relationship instead of assuming that either code covers every supplied unit.
This guide is a buyer’s record framework. It does not certify an offered batch or promise that every type of record exists. The COA checklist covers the contents of an analytical document; this guide connects that document with purchasing and receipt.
Keep one row per supplied lot.
| Record | Matching fields | Open question |
|---|---|---|
| Accepted quotation | Variant, identity, content basis, quantity and revision | Has anything changed since acceptance? |
| Lot allocation | Supplier lot identifier and quantity assigned | Is more than one lot included? |
| Laboratory report | Sample reference, report reference and lot relationship | Which supplied material does it cover? |
| Packaging record | Presentation, component scope and artwork revision | Which configuration was packed? |
| Delivery and receipt | Shipment reference, received lots and quantities | Do received units match the accepted order? |
Keep unresolved fields visible. A purchasing summary should not turn a missing lot connection into a completed check merely because a report is attached.
Link identifiers to what happened.
GS1’s primary traceability overview distinguishes tracking events, such as packing or shipping, from the data describing those events. Read the GS1 traceability overview. It is useful background for designing a record chain; it is not evidence that our batches use GS1 identification or certification.
For your procurement file, ask which event a record describes and when it occurred. Keep allocation, packaging, dispatch and receipt apart. An order confirmation establishes an accepted order; it does not establish that the buyer has received the goods.
Preserve any change notice alongside the original accepted record. If the allocated lot changes, ask for the matching replacement documentation before summarising the order as complete.
Do not merge different batches into one line.
If a delivery contains two BPC-157 lots, retain two lot rows with their respective quantities and document references. The same applies when several shipments fulfil one order. Reconcile the received total while preserving the separate record chains.
Ask whether a report covers one tested sample, one stated lot or another explicitly defined scope. Do not extend a result to another lot because the product name is unchanged. The purity and content guide explains why different analytical measurements also need separate fields.
A report revision should remain identifiable. Record which version was reviewed and why a later version replaced it, if applicable. Keep the original correspondence so a reviewer can follow the clarification.
Track packaging changes beside the lot.
For an OEM or private-label project, request the accepted artwork revision and supplied configuration. A branding revision and a material lot are different identifiers. Changing a carton design does not establish a new analytical result.
For Semax or Selank, specify whether the order concerns vials or a defined kit presentation. Record the actual supplied component scope; do not assume a material report covers every kit component. Use the vial and kit guide to prepare that configuration brief.
Compare the arrival with the agreed order.
At receipt, record the observed identifiers, quantities and any visible discrepancy. Preserve packaging photographs and relevant delivery references in your own procurement file. If a label is unreadable or a lot differs from the agreed allocation, ask for a reconciliation rather than rewriting the record to match the quote.
Keep the destination in the USA, Canada or Australia, current dispatch confirmation and actual receipt separate. Local availability needs confirmation for the selected specification. No lot code alone establishes storage history or a delivery guarantee.
Ask for a precise reconciliation.
Send the named peptides, accepted specification, presentation, quantities by variant and destination. Ask for the offered lot identifiers, their document references and any unresolved scope. If you already have a quote, include its reference and revision.
