Synthesis partner review
Compound class, manufacturer file, format and batch-level traceability checked before quoting.
Quality & documentation
Show the lot. Then ask for the order.
Every PeptiOEM lot ships with a buyer-verifiable document pack: COA, HPLC chromatogram, MS identity, water content, lot file and packaging proof. Sourcing decisions rest on data, not slogans.
Per-batch document pack
What ships with every lot.
Documentation is the deal. We do not invoice without context, and we do not ship without a lot file.
| Evidence | What buyers see · Purpose |
|---|---|
| Certificate of Analysis (COA) | Batch-level certificate with compound identity, purity, lot code and document date. Baseline procurement file for med spa, clinic, 503A and OEM buyers. |
| HPLC purity | Reverse-phase HPLC chromatogram (UV) with ≥99% area-purity target on flagship compounds. Purity review before purchase and reorder. |
| MS identity | Mass spectrometry identity confirmation against the compound reference profile. Identity confirmation for research and OEM use. |
| Water content | Lyophilized vials report water content (typical ≤4%) on the COA. Stability and storage planning. |
| Lot traceability | Lot code printed on vial label, repeated in document pack and carton outer. Reorders cite prior lot for continuity. |
| Packaging proof | Vial label, carton text, insert and lot-code placement reflected before production. OEM and repeat-procurement confidence. |

FAQ
Questions buyers ask before placing a quote.
Do you ship a COA with every lot?
Yes — every lot ships with a Certificate of Analysis showing HPLC purity, MS identity, water content and lot traceability. HPLC and MS chromatograms are available on request.
Can I get a sample COA before placing an order?
Yes. Add compounds to the quote builder and we will share a representative sample COA along with the quote. Production COAs ship with the lot itself.
What is your HPLC purity target?
≥99% area purity on flagship compounds (BPC-157, Sermorelin, Ipamorelin, Tirzepatide, Semaglutide). Other compounds carry their own published targets — see individual product pages.
Do you provide third-party testing?
Third-party testing on representative lots is available on request as part of the document pack negotiation. Pricing depends on the assay set and turnaround.
How are lot codes structured?
Compound prefix + lot serial (e.g. BPC-10-2026Q2-A). The full lot-code structure is locked at packaging-proof step for repeat OEM supply.
