Learn About Our Process

Why >99% Purity Standards Matter for Research Peptides

Our high-purity research peptides are third-party tested to exceed 99% purity, ensuring reliable lab results and minimizing contaminants. With BioRegen’s advanced testing for purity, quantification, heavy metals, and endotoxins, we provide transparent COAs for every batch of lab-grade peptides.

Our Rigorous Process for >99% Pure Research Peptides

We source peptides from trusted production laboratories, then quarantine each batch until BioRegen performs independent testing for Purity (>99% standard), Quantification, Heavy Metals, and Endotoxins. Only upon passing are batches released, tagged, COAs published, and made available as high-purity lab peptides for sale.

Frequently Asked Questions About Our Peptide Testing and >99% Purity Standards

Get answers to common questions about our third-party tested high-purity research peptides, COAs, and testing process.

What tests are performed to ensure >99% purity in our research peptides?

Every batch is tested by BioRegen for Purity (using UPLC to confirm >99% standards), Quantification (measuring exact peptide content), Heavy Metals (detecting traces like lead or mercury), and Endotoxins (ensuring no bacterial contaminants). These comprehensive tests guarantee our peptides are safe and effective for lab use.

How is purity measured for our high-purity lab peptides?

Purity is measured via Ultra Performance Liquid Chromatography (UPLC) and mass spectrometry at BioRegen. This identifies and quantifies the peptide while detecting impurities, ensuring our >99% purity standard is met or exceeded for reliable research outcomes.

What happens if a batch fails the >99% purity or other tests?

If a batch doesn't meet our strict >99% purity standards or fails any test (e.g., high heavy metals or endotoxins), it remains quarantined and is not released for sale. We either re-source or discard it to maintain quality—transparency is key, so failed batches aren't offered.

How long does third-party testing take for our peptides?

Testing typically takes 1-2 weeks from sample submission to BioRegen. We quarantine batches during this time, and upon passing, COAs are published promptly so you can access high-purity peptides without delays.

Are COAs available for all batches of our >99% pure research peptides?

Yes, every released batch has a unique COA detailing all test results, including >99% purity verification. Download them directly from our site or request via contact for specific third-party tested peptide batches.

Why choose PeptiSearch for third-party tested high-purity peptides?

We prioritize >99% purity with independent BioRegen testing, providing detailed COAs for transparency. Our process ensures contaminant-free, quantifiable peptides ideal for laboratory research, backed by US-based quality standards.
