Our Commitments

Six Pillars of the Decode Standard™

01

Raw Material Sourcing

We source APIs exclusively from GMP-certified facilities with documented supplier qualification and incoming material inspection for every lot.

02

Lyophilization & Filling

Compounds are lyophilized (freeze-dried) in a controlled environment to ensure long-term stability and eliminate moisture-related degradation.

03

HPLC Purity Analysis

Reversed-phase high-performance liquid chromatography (RP-HPLC) is performed on every batch. Our specification is ≥99.0% purity — we publish the exact figure in every COA.

04

LC-MS/MS Identity Confirmation

Liquid chromatography–tandem mass spectrometry confirms the molecular identity of each compound against a reference standard before any batch is released.

05

Endotoxin & Heavy Metal Testing

All batches undergo LAL (limulus amebocyte lysate) endotoxin assay targeting <5 EU/mg, plus ICP-MS heavy metals screening to <20 ppm.

06

Full Batch Traceability

Every vial carries a batch number (DP-YYYY-XXX-NNN) linked to a full COA you can verify online at any time. No hidden results, no generic certificates.

Sourcing

Raw Material Sourcing

Our raw APIs (active pharmaceutical ingredients) are sourced exclusively from GMP-certified manufacturers with full documentation. Every supplier undergoes a formal qualification process before any material enters our inventory.

Incoming materials are inspected and held in quarantine until identity testing is complete. Only materials that pass our incoming quality control (IQC) specification are released for production.

  • Supplier qualification audit before first purchase
  • Material Safety Data Sheets (SDS) reviewed for all incoming APIs
  • Incoming purity check by RP-HPLC before use
  • Temperature-controlled storage from receipt through dispatch
GMP-Grade APIs Only

We do not source APIs from unverified commodity suppliers. Every material is traceable to its manufacturing facility.

Testing Protocol

What We Test — And Why

Test Method Specification Why it Matters
Appearance Visual White/off-white lyophilized powder Confirms correct physical form and absence of contamination visible to the eye.
Identity (LC-MS/MS) Liquid chromatography–tandem mass spectrometry Conforms to reference standard Definitively confirms the compound is what the label states — mass spectrometry cannot be fooled by look-alike impurities.
Purity (RP-HPLC) Reversed-phase HPLC ≥99.0% Measures the proportion of the desired compound vs. all other substances. The industry gold standard for peptide purity.
Assay / Content HPLC vs. external standard 95.0–105.0% Confirms the actual amount of compound present, ensuring label dosage is accurate.
Bacterial Endotoxins LAL (Limulus Amebocyte Lysate) <5.0 EU/mg Endotoxins from gram-negative bacteria can interfere with cell culture and in vitro assays. LAL testing is the pharmacopeial standard.
Heavy Metals ICP-MS <20 ppm total Traces of heavy metals can inhibit enzymes and compromise research results. ICP-MS detects metals at ppb levels.
Residual Solvents GC Headspace (GC-HS) ICH Q3C limits Solvents used in synthesis must be removed. GC-HS verifies levels are below internationally accepted safety thresholds.
Moisture (LOD) Karl Fischer titration ≤6.0% Excess moisture in lyophilized peptides degrades stability. Karl Fischer is the reference method for precise water content determination.
Traceability

How Batch Tracking Works

Each production run is assigned a unique batch number following the format DP-YYYY-XXX-NNN, where:

  • DP — Decode Peptides identifier
  • YYYY — Year of manufacture
  • XXX — 3-letter compound code (e.g., BPC, EPI, IGF)
  • NNN — Sequential batch number for that compound

The batch number is printed on the vial label. You can verify any batch at any time using our online Batch Lookup tool — no account required.

COA Guide

How to Read Your Certificate of Analysis

1

Product & Batch Information

Confirm the product name and batch number match what is on your vial label. The manufacture date and retest date tell you how long the compound remains within specification.

2

Test Results Table

Each row shows the test name, the specification limit, the actual result achieved, the analytical method used, and a PASS/FAIL status. All rows should show PASS for a released batch.

3

Purity Figure

The HPLC purity result (e.g., 99.4%) tells you the percentage of the compound in the sample. Our minimum specification is 99.0% — values above this are typical for Decode batches.

4

Conclusion & Analyst

The conclusion line summarises the overall batch decision: "PASS — Released for research use" means all tests were within specification and the batch was approved by the QC department.

Storage & Shipping

Storage Requirements & Cold-Chain Shipping

−20 °C Storage (Lyophilized)

Most lyophilized peptides should be stored at −20 °C when not in use. Reconstituted solutions should be aliquoted and stored at −80 °C for long-term stability.

Cold-Chain Delivery

All orders are shipped with gel ice packs inside insulated boxes to maintain 2–8 °C during transit. Shipping is expedited to minimise time outside controlled storage.

Tamper-Evident Packaging

Every vial is sealed with tamper-evident closures. The outer packaging includes batch number, product name, storage instructions, and a QR code linking to the COA.

Compliance

Research Use Only — What This Means

All compounds supplied by Decode Peptides are labelled "For in vitro research use only. Not for human or veterinary use." This designation is a legal and scientific classification, not a marketing statement.

What it means in practice:

  • Compounds are intended for laboratory research only (cell culture, biochemical assays, molecular biology)
  • Products have not been evaluated or approved by any regulatory authority (EMA, FDA) for human use
  • We do not provide dosage, administration, or therapeutic advice of any kind
  • Purchasing confirms you are a qualified researcher using compounds within a research context

This allows Decode Peptides to legally supply high-purity compounds to researchers across the EU while maintaining strict compliance with applicable regulations.

Not for human use

These compounds are not medicines, supplements, or food products. They are not intended to diagnose, treat, cure, or prevent any disease or condition.
