All peptides supplied by Prime Science are provided in lyophilized (freeze-dried) form and require reconstitution prior to use.

Bacteriostatic water is required for this process and is sold separately. For quality and consistency, we recommend using pharmaceutical-grade bacteriostatic water only. Use of unverified or off-brand solutions is not advised.

Every research peptide offered by Prime Science is independently tested by Testides, one of the most respected third-party laboratories in Canada.

Each product is paired with batch-specific analytical reports, allowing you to review purity, identity, and testing data and match it directly to the batch you receive. If a compound is not verified through third-party testing, it is not listed for sale.

Transparency and documentation are non-negotiable at Prime Science. We believe informed buyers should be able to verify exactly what they are sourcing—without relying on claims or assumptions.
