COA & Document Library

Q: What does a PeptideDistro.com COA include?

Each lot-specific certificate of analysis lists peptide name and sequence reference, lot or batch number, manufacture and expiration dates, HPLC purity result against the lot release threshold, observed mass from ESI-MS or MALDI-TOF, appearance, water content where applicable, storage conditions, and the name of the issuing reviewer. COAs are intended to support research-use documentation only.

What is held in the document library

PeptideDistro.com maintains a per-lot document record for every research peptide, custom blend, and private-label kit released through wholesale fulfillment. The document library is the routing point for buyers who need to retrieve those records for procurement, audit, and research-workflow context. The library is not a public download index because lot data is tied to qualified-buyer accounts.

COA

Certificates of analysis

Lot-specific COAs covering identity, HPLC purity against the lot release threshold, observed mass, appearance, lot/expiration, and storage conditions.

Packet

Batch documentation packets

Bundled packets for wholesale and private-label lots: COA, HPLC chromatogram, MS spectrum, fill counts, label artwork, and component sourcing where applicable.

HPLC

HPLC chromatograms

Reverse-phase HPLC chromatograms with retention behavior and impurity profile for the released lot. Available alongside the COA on request.

MS

Mass spectrometry spectra

ESI-MS or MALDI-TOF spectra with observed-versus-expected mass annotation. Available alongside the COA for identity confirmation in research workflows.

Lot

Lot & expiration records

Lot numbers, manufacture dates, stability windows, storage conditions, and reviewer name. Preserved against the buyer account record for documentation continuity.

Custom

Custom blend & white-label records

Composition, label artwork, intake-spec confirmation, and packaging records for custom blend or private-label lots. Routed alongside the COA to the buying account.

What a PeptideDistro.com COA contains

Compound identity: peptide name, sequence reference, modifications, and catalog SKU.
Lot or batch number with manufacture and expiration dates and stated stability window.
HPLC purity against the lot release threshold, with chromatogram cross-reference.
Observed mass from ESI-MS or MALDI-TOF, expected mass, and identity-confirmation note.
Appearance, water content where applicable, and physical form (lyophilized powder, solution).
Storage conditions and handling guidance applicable to research workflow.
Issuing reviewer and release date for the lot record.
RUO statement: for in vitro research use only; not for human or veterinary consumption.

COAs do not contain dosage, administration, treatment, or clinical-use guidance. PeptideDistro.com does not produce clinical, therapeutic, or consumer-facing labeling.

Batch documentation packet — included fields

01

Identity confirmation

Sequence reference, modifications, catalog SKU, and PubChem / CAS / UniProt cross-references where applicable.

02

Analytical results

HPLC purity result, chromatogram, retention notes, observed mass from MS, and identity-confirmation summary.

03

Lot release fields

Lot/batch number, manufacture date, expiration, stability window, storage conditions, reviewer name, release date.

04

Fill & packaging

Vial size, fill count, packaging configuration, and label artwork (for private-label and custom-blend lots).

05

Sourcing trail

Manufacturing partner reference, raw-component inputs (where applicable), and lot-traceability notes preserved against the buyer record.

06

Compliance attestations

Research-use-only statement, qualified-buyer status reference, and RUO disclaimer aligned with the wholesale terms.

Document request process

01Submit

Send the request form below or contact the wholesale desk with compound, lot number if known, and account context.

02Review

The desk confirms account status against the buyer record and the research-use attestation on file.

03Route

The lot record (COA + chromatogram + MS spectrum) or the requested packet is routed to the account contact email.

04Track

Each released document is tied to the buyer account record and the source lot for documentation continuity.

First response from the desk is typically within one to two business days for complete submissions. Sample documentation packets are routed without account approval; lot-specific records require a qualified buyer account.

Document request

Request a lot-specific COA, batch documentation packet, HPLC chromatogram, MS spectrum, or sample documentation packet. The wholesale desk reviews account context before routing the record.

Research-workflow context for this document

Research-use attestation (required) I confirm this document request is for legitimate scientific research, procurement diligence, audit, or wholesale operations only. Records will not be used to support human or animal consumption, therapeutic claims, or downstream resale as drugs, supplements, or cosmetics. See Compliance Overview. I have read and agree to the Terms of Service, Privacy Policy, and Wholesale Terms. Lot-specific records are released only to approved wholesale accounts and remain tied to the buyer record.

Submissions are routed to the wholesale desk and persisted with a request reference number. First response typically within one to two business days.

Use Quote Desk Instead

Routing options

All paths lead to the same desk. Use whichever fits your workflow.

Sample documentation packet

Pre-application diligence is supported. Indicate “Sample COA / sample documentation packet” on the form. Sample packets do not certify a specific lot.

Bundle with a quote

If you are also requesting pricing, route through the quote desk with COA intent so the desk can return pricing and documentation in one reply.

Open a wholesale account

Lot-specific records ship faster once the buyer account is on file. Open Wholesale Application

QA process reference

The Quality Assurance page documents the supplier-qualification, identity, purity, and lot-release process behind every record in this library.

Frequently asked questions

What does a PeptideDistro.com COA include?

Each lot-specific COA lists peptide name and sequence reference, lot or batch number, manufacture and expiration dates, HPLC purity result against the lot release threshold, observed mass from ESI-MS or MALDI-TOF, appearance, water content where applicable, storage conditions, and the issuing reviewer. COAs are intended to support research-use documentation only.

Why are COAs not posted publicly on each peptide page?

COAs reference lot-specific manufacturing data and qualified-buyer information. Records are released to approved wholesale accounts so that the document trail stays tied to the buyer record. Sample documentation packets are available on request for procurement diligence.

How do I request a COA for a specific lot or compound?

Submit the document request form on this page with the compound, lot number if known, and account context. The wholesale desk reviews the request, confirms account status, and routes the lot record. First response is typically within one to two business days.

Can I get a sample COA before opening an account?

Yes. Approved buyer prospects can request a redacted sample COA and a sample batch documentation packet. Indicate “sample documentation packet” on the form. Sample packets do not certify a specific lot.

What is the difference between a COA and a batch documentation packet?

A COA is the single-page lot release document. A batch documentation packet bundles the COA with the underlying HPLC chromatogram, mass spectrometry spectrum, lot/expiration data, fill counts, and (for private label or custom blend lots) label artwork and component sourcing where applicable.

How long are lot records preserved?

Lot records are preserved against the buyer account record for documentation continuity through the stated stability window of the lot and beyond, consistent with the wholesale terms. Records can be re-routed on request after the original release.

Research use only

Documentation released through this library is intended to support research-grade procurement and lot-record diligence. PeptideDistro.com does not provide medical, dosage, treatment, or clinical guidance, and lot records do not certify products for human or veterinary consumption.
