One marketplace.
Verified manufacturers only.
Arias Peptides does not manufacture. We list research compounds from manufacturers who meet a strict, published testing standard — independent lot-level Certificates of Analysis, reproduced unaltered. Axis Bio Lab is our first verified manufacturer; the door is open to brands who test the same way.

Listing standard
What every manufacturer must meet.
01
Independent COA per lot
Every lot must carry a Certificate of Analysis from a third-party analytical laboratory — HPLC purity and LC-MS identity at minimum.
02
Unaltered reproduction
Certificates are published on Arias Peptides exactly as issued. We never edit, summarize away, or re-brand a supplier's analytical record.
03
Research-use-only labeling
Vials, inserts and listings must be labeled for in-vitro laboratory research. No dosing, no wellness or therapeutic language.
04
Lot traceability
Lot numbers on the vial, on the COA and in our catalog must match, so a buyer can audit the chain from bench to batch.
05
Cold-chain handling
Lyophilized materials stored at -20°C, liquids at 2–8°C, with insulated, temperature-monitored dispatch.
06
Purchaser Agreement compliance
Suppliers honor the same Research Purchaser Agreement every buyer signs — orders flagged by compliance review are declined.
