Verification & Testing

Independent Laboratory Verification

At Oneday Compounds, every production lot is independently third-party tested by a U.S. ISO/IEC 17025:2017 accredited laboratory before release.

We believe research materials deserve more than minimum testing standards. Every lot undergoes structured third-party verification to confirm identity, purity and safety.

Why ISO Accreditation Matters

ISO/IEC 17025 is the international standard for scientific testing laboratories.

For example: real sterility testing at an ISO/IEC 17025 accredited lab requires:

USP <71> sterility protocol

Which involves:

  • sterile isolator environment
  • validated culture media
  • 14-day incubation
  • dual media testing (FTM + TSB)
  • microbial growth monitoring

Many labs do not actually run full USP <71> protocols, even if they say “sterility”.

Without ISO accreditation there is no audit verifying they actually follow USP methods. In other words: you are just trusting their word.

Many research peptide suppliers publish COA’s or reports from laboratories that are NOT ISO-accredited, meaning testing procedures are not externally audited.

This is why researchers at Pharma companies and Universities rely on ISO/IEC accredited labs.

We solely Test with a Third-Party ISO-Accredited Lab

Accredited laboratories must operate under strict quality control systems inlcuding:

  • validated analytical methods
  • calibrated instrumentation
  • environmental contamination controls
  • documented procedures
  • routine external audits

This ensures testing results are accurate, reproducible, and independently verified.

At Oneday Compounds we are proud to be implementing a higher standard of testing and advancing verification practices of our materials for researchers.

Our 7-Point Verification Standard

Every production lot is independently third-party tested for:

  1. Identity – Verified via compound-specific chromatographic fingerprinting (HPLC) against reference standards
  2. Net Content (Weight) – Confirms labeled quantity accuracy.
  3. Purity (≥99% HPLC) – High-performance liquid chromatography confirms purity.
  4. Conformity (Multi-Vial Verification) – Confirms consistency across multiple vials per lot
  5. Sterility (USP <71>) – Validated sterility testing confirms absence of microbial growth.
  6. Endotoxins (LAL) – Detects bacterial endotoxins not identified with sterility testing alone.
  7. Heavy Metals (ICP-MS) – Screens for trace contaminants including lead, arsenic, cadmium, and mercury (only released if within established safety thresholds).

Lots are not released until all testing meets our internal verification standards.

Complete Transparency

Full Certificate  of analysis are published for every product and every lot we release.

Because transparency shouldn’t be optional.
