Company Overview

Epitagen operates as a B2B wholesale supplier that coordinates selected manufacturing partners in China for commercial procurement and resale. The company's offerings are aimed exclusively at qualified distributors, resellers, commercial catalog buyers, and procurement teams rather than individual consumers. The site publishes catalog specifications for research peptides, ordering workflows, documentation scopes, and global logistics information.

The site states that available batch documentation can include Certificates of Analysis, HPLC chromatograms, and mass spectrometry data upon review. According to the company, purchasing is conducted via multi-product inquiries and executed through Proforma Invoices with payment accepted via T/T wire or approved cryptocurrency. The supplier coordinates global fulfillment through carriers like FedEx, DHL, and UPS, while buyers must inquire directly regarding custom packaging, specific lead times, and testing laboratory details.

Pros
  • Consolidated multi-product inquiries across various research peptides
  • Batch documentation including COA, HPLC, and mass spectrometry available for review
  • Flexible minimum order quantity of 5 boxes mixable across multiple SKUs
Considerations
  • No public pricing displayed on the platform
  • Physical corporate headquarters address not stated publicly
  • Orders are final upon payment clearance with no routine returns

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 50% (needs 60%)
  • Testing & Documentation 44% 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.
