With more than 20 years of hands‑on experience, the team excels at transforming complex peptide designs into robust, reproducible manufacturing processes.
The team specializes in process design for long‑chain and modified GLP‑1 class peptides, with established expertise in sequence optimization, long‑acting modification strategies, and process implementation—supporting technically demanding development‑stage programs.

Building on strong R&D foundations and deep peptide chemistry expertise, we translate development capabilities into flexible, project-specific custom peptide solutions.

Comprehensive Custom Peptide Synthesis Capabilities

From Sequence Design to Impurity Control — We Deliver More Than Peptides, We Deliver Solutions

Successful peptide development hinges not only on synthesis, but also on a thorough understanding of sequence complexity, structural behavior, modification strategy, and quality risk control.We provide end-to-end custom peptide solutions, supporting clients from early research through advanced preclinical and pharmaceutical applications.

Customized Amino Acid Sequences

Designing Challenging Sequences

Broad Length Coverage

Reliable synthesis of peptides ranging from short sequences (2–10 amino acids) to long peptides exceeding 100 amino acids, with consistent yield and batch reproducibility.

Special and Non-Natural Building Blocks

Full compatibility with D-amino acids, non-natural amino acids (e.g. Cit, Orn, Abu), β-amino acids, and other customized monomers beyond the 20 canonical amino acids.

Advanced Solutions for Difficult Sequences

Targeted strategies for highly hydrophobic, aggregation-prone, or cysteine-rich peptides, supported by sequence feasibility evaluation, optimized coupling protocols, and microwave-assisted peptide synthesis technologies.

Modification Versatility

Enabling Functionality Through Precise Structural Engineering

Peptide modification is critical for tuning biological activity, stability, and pharmacokinetic properties. We offer a comprehensive portfolio of standard and advanced modifications.

Salt Form & Counter-Ion Control

Precision Down to the Final Chemical Form

Salt form selection plays a critical role in peptide stability, solubility, and experimental reproducibility. We provide precise control tailored to downstream applications.

  • Common Salt Forms: TFA salts (default), Acetate salts, and Hydrochloride (HCl) salts.
  • Desalting: Ultra-low residual TFA levels (<1%) achievable.
  • Customized: Sodium, ammonium, and other customized salt forms available.

Impurity Profile & Quality Insight

The True Measure of Professional Peptide Manufacturing

Quality excellence extends beyond the main peak. Our impurity profiling strategy reflects a deep understanding of synthesis-related risks.

  • Process-Related Impurity Control
    Identification and control of deletion sequences, incomplete deprotection products, and oxidation-related impurities.
  • Water Content & Residual Solvent Testing
    Strict monitoring of moisture levels and residual organic solvents to ensure stability and regulatory readiness.
  • Endotoxin Control
    Endotoxin testing available for peptides intended for cell-based and animal studies, with levels as low as <0.01 EU/mg, ensuring biological assay integrity. achievable.
  • Customized: Sodium, ammonium, and other customized salt forms available.
