Company Overview
The company states it is a Canadian-owned and operated research peptide supplier based in Durham Region, Ontario, offering products strictly for laboratory and research use. The site features a catalogue of single peptides, multi-peptide blends, capsules, and atomizers categorized into research areas such as healing, metabolic, and anti-aging. The site notes that all products are 100% synthetically manufactured without animal derivatives.
The company says that every batch undergoes independent third-party testing by Janoshik Analytical using HPLC and mass spectrometry, with Certificates of Analysis available upon request. Orders are paid via Interac e-Transfer and shipped same-day via Canada Post Xpresspost for orders confirmed before 4:00 PM EST. Buyers would still need to contact support to request specific lot analytical documentation or inquire about unlisted items.
Pros
- Every batch is verified through third-party HPLC and mass spectrometry testing by Janoshik Analytical.
- Same-day dispatch is available for orders confirmed before 4:00 PM EST.
- Products are 100% synthetically manufactured with zero animal derivatives.
Considerations
- Shipping is restricted exclusively to Canada.
- Payment options are limited to Interac e-Transfer.
- Certificates of Analysis are provided upon request rather than published publicly on the site.
Score Breakdown
Not currently ranked. We hold suppliers out of the numbered rankings until enough of the rubric has been verified, so that missing information can never work in a supplier's favour:
- overall evidence coverage 37% (needs 60%)
- Testing & Documentation 44% verified (needs 60%)
- Wholesale Capabilities 11% verified (needs 60%)
The dimension scores below reflect only what we were able to verify.
Overall score is calculated from these seven dimensions using the house weighting, and each dimension is calculated from the verified criteria beneath it. Open a dimension to see every criterion, its verified state, the source it was verified from and the date it was checked. Comparison pages may re-weight the dimensions for buyer intent.
