Research-Grade Peptides,
Documented Batch by Batch
Synthesis Peptides supplies synthetic peptides and reference compounds to laboratories, universities, and research organizations across the United States. Every production lot is analyzed by an independent testing facility, and every shipment is accompanied by the Certificate of Analysis for that lot.
Every batch has a paper trail.
We do not ask laboratories to accept purity on trust. Each production lot is submitted to an independent, HPLC-equipped analytical facility, and the resulting Certificate of Analysis is published against the lot number printed on the vial.
The specification shown on a product page is the specification on that certificate — figures are reported as measured, not rounded upward for presentation.

Identity confirmed by HPLC, with mass spectrometry applied to relevant lots.
Purity reported as a measured value against a stated method.
Lot number on the vial matches the lot number on the certificate.
Archived certificates remain retrievable after a lot is depleted.
Built for temperature-sensitive transit.
Peptides are supplied as lyophilized powder in sealed borosilicate vials, labeled with compound name, quantity, lot number, and the research-use statement. Orders are packed for temperature-sensitive transit and dispatched from our Las Vegas facility.

A business-to-business supplier.
Our accounts include academic research groups, contract research organizations, analytical and testing laboratories, and product development teams that require characterized reference material with traceable documentation.
How material is sourced and released.
Material moves through four stages before it appears in the catalog. A lot that fails at any stage does not proceed to the next one.
Sourcing
Candidate material is sourced against the required identity and purity specification.
Independent Testing
Each production lot is submitted to an independent, HPLC-equipped analytical facility.
Certificate Review
Results are reviewed against identity and purity thresholds before a lot is approved.
Released to Catalog
Approved lots are listed with their Certificate of Analysis attached.
