Why our peptides

Provenance is not a feature. It is the premise.

Most research peptides reach the bench through a chain nobody can name. Ontario Bio Sciences was built to refuse that. Every preparation is synthesized to research grade, lyophilized for stability, and assayed by an independent laboratory — and every result is written down. When the protocol asks where it came from, there is an answer.

Purity is verified by reverse-phase HPLC and reported per batch. A certificate of analysis accompanies every order. Sequences, molecular formulae and storage conditions are documented on each product page — verifiable, not asserted.

Questions, answered

On purity, sourcing & research use.

Every batch is assayed by an independent laboratory using reverse-phase high-performance liquid chromatography (HPLC). A batch-specific certificate of analysis is available for every product, and the lot reference ships with your order. We publish the standard, and we can show you the document.
Products ship as lyophilized (freeze-dried) powder in sealed vials, dispatched under cold chain. Store at −20°C and protect from light. Reconstitute with bacteriostatic water per your research protocol. Recommended handling is listed in the specifications on each product page.
No. Ontario Bio Sciences products are sold strictly for research use only (RUO). They are not for human or veterinary consumption, and have not been evaluated by the FDA for safety or efficacy. They are intended exclusively for laboratory and educational research by qualified professionals.
