Verified at Every Step

Our multi-layered quality control protocol ensures that every peptide meets the highest standards of purity and identity.

HPLC Analysis

Every batch undergoes reverse-phase HPLC to verify purity ≥98%. Chromatograms included with each order.

Mass Spectrometry

MALDI-TOF and ESI-MS confirmation of molecular weight and peptide identity for every synthesized batch.

Full COA Included

Detailed Certificate of Analysis with each product — including purity, identity, and amino acid analysis.

FDA-Registered Facilities

All peptides are synthesized in FDA-registered, cGMP-compliant laboratories with full traceability.

Cold-Chain Logistics

Temperature-controlled shipping with insulated packaging and ice packs to preserve peptide integrity.

Batch Traceability

Every vial carries a unique batch number traceable to its synthesis, purification, and quality records.

Our Process

From Synthesis to Your Bench

A rigorous four-stage workflow ensures every peptide arrives pure, verified, and ready for your research.

01

Solid-Phase Synthesis

Peptides are synthesized using Fmoc solid-phase methodology on automated synthesizers with controlled coupling cycles.

02

Purification

Reverse-phase HPLC purification removes truncated sequences and deletion peptides, achieving ≥98% target purity.

03

Analytical Verification

Identity confirmed by mass spectrometry. Purity quantified by analytical HPLC. Lyophilized for maximum stability.

04

Cold-Chain Delivery

Each vial is sealed, labeled with batch tracking, and shipped in insulated cold-chain packaging to your lab.
