Company Overview
The company operates as a research chemical supplier focusing on synthetic peptides for scientific research, targeting academic institutions, universities, and commercial buyers. The site publishes an in-stock catalog of over 400 peptides, volume discount tiers, and custom synthesis specifications. The business model accommodates both standard catalog purchases and bespoke synthesis requests for professional researchers.
The company says that every order includes a Certificate of Analysis, with batch purity verified through reverse-phase HPLC and mass spectrometry. Standard orders require upfront payment, whereas approved wholesale accounts can access Net-30 terms and priority processing. Prospective buyers must inquire directly regarding exact physical street addresses and specific customs documentation requirements for non-standard jurisdictions.
Pros
- Guaranteed minimum purity of ≥98% for catalog items.
- Certificate of Analysis included with every order.
- Tiered volume discounts ranging from 5% to 20%+ for wholesale accounts.
Considerations
- Specific physical street address is unstated beyond England and Wales.
- Custom synthesis orders enforce a 100mg minimum per sequence.
- Catalog prices exclude VAT, import duties, and shipping costs unless otherwise specified.
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 56% (needs 60%)
- Testing & Documentation 28% 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.
