Identity & purity data

Verified quality

Certificate of Analysis on every batch

Third-party tested against an ISO/IEC 17025 accredited standard. Each certificate records the compound, the lot, the test date and the measured purity — so you can verify exactly what you received.

Identity confirmed

Every lot is checked for identity before it is released.

Purity measured by HPLC

Reverse-phase HPLC quantifies purity against our 99%+ standard.

Documented per lot

The certificate names the exact lot number and test date.

Batch-specific certificates are published with each production lot. Request the COA for any lot you have received and we will send it through.

Why researchers choose us

Quality that begins with sourcing and ends with transparency

We treat purity as a measurable specification, not a marketing line. Raw materials are verified before synthesis, and each finished batch is analyzed by reverse-phase HPLC to confirm it meets our 99%+ standard. Everything is lyophilized for stability, sealed for transit, and supported by a Canada-based team.

Purity you can verify

Reverse-phase HPLC confirms a 99%+ purity standard on every batch we release.

Controlled synthesis

Peptides are produced under documented, repeatable synthesis conditions.

HPLC purification

Multi-stage purification isolates the target compound from process residues.

Batch documentation

A Certificate of Analysis accompanies every batch, with identity and purity data.

Frequently Asked Questions

Everything you need to know about ordering research peptides.

How pure are your peptides?

Every compound we list is produced to a 99%+ purity standard and verified by high-performance liquid chromatography (HPLC) before it reaches inventory. Purity is measured per batch, and the result for the exact lot you receive is recorded on its Certificate of Analysis.

What is a Certificate of Analysis (COA), and is one included?

A Certificate of Analysis is a lab-generated document reporting the identity and purity of a specific manufacturing lot. A COA accompanies every batch we release, so the data is in your hands before the vial reaches the bench.

Where do you ship, and how fast?

We ship across Canada from within Canada, in discreet packaging. Orders are dispatched within 0–2 business days. Shipping is a $9.99 CAD flat rate, and free on orders over $150 CAD.

How should these compounds be handled?

All products are supplied as lyophilized powder for in-vitro laboratory research use only. Store as indicated on the vial. These products are not for human or veterinary use and not for use in diagnostic procedures.
