Company Overview
The site states that Costides operates a wholesale storefront offering Research Use Only peptide 10-pack vials and kits for laboratory procurement and channel resellers. According to the company, catalog listings display case-quantity pack pricing, per-vial math, item numbers, and CAS identity references. The supplier explicitly notes that products are intended strictly for laboratory research and not for human or veterinary use.
For quality documentation, the company publishes lot-pinned Certificates of Analysis featuring HPLC and mass spectrometry testing when lot files are released. The purchasing workflow allows guest checkout with required RUO attestation, while wholesale accounts provide buyer desks and invoice terms upon request. Orders are fulfilled through a US warehouse channel typically within one to three days in stock, though buyers must verify inventory availability or custom requests not featured on the standard catalog floor.
Pros
- US warehouse shipping with typical 1–3 day fulfillment for in-stock orders
- Lot-pinned Certificates of Analysis providing HPLC and mass spectrometry results when published
- Automatic quantity-based discount tiers applied at checkout
Considerations
- No dosing, reconstitution, or clinical treatment guidance provided
- Specific analytical testing laboratory names are unstated on published documentation
- International shipping restrictions and regional stock limitations apply
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 47% (needs 60%)
- Wholesale Capabilities 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.
