 About Us

We are a high-tech enterprise specializing in the R&D, manufacturing and distribution of research-grade peptide reagents. Our GMP-standard clean rooms are equipped with automated solid-phase peptide synthesizers, enabling production from milligram to multi-kilogram scale. Our quality management system is ISO 9001 certified. Every batch is rigorously tested by HPLC, mass spectrometry and endotoxin assays, with a batch Certificate of Analysis (COA) provided. Our products are exported to research institutions, pharmaceutical companies and university laboratories across Europe, North America and Southeast Asia. 

Product Applications

Epithalon (also known as Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly), identified as the active short-peptide component of Epithalamin — a polypeptide extract derived from the pineal gland.

Process Advantages & Supply Capability

• Synthesis: Solid-phase peptide synthesis (SPPS) with high coupling efficiency and low racemization.
• Purification: Preparative HPLC purification, achieving purity above 99%.
• Quality control: Every batch is accompanied by HPLC purity report, MS identity report and endotoxin report; third-party testing available on request.
• Supply: In-stock vials of 10 mg / 50 mg / 100 mg ship within 1 business days; multi-kilogram custom orders typically lead in 24 hours.
• Packaging: Sealed sterile lyophilized vials with aluminum crimp seals, labeled with batch number and manufacturing date.

Q1: What is Epithalon? A: Epithalon (also called Epitalon) is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly. It was identified as the active short-peptide component of Epithalamin, a polypeptide preparation isolated from the pineal gland.

Q2: What is the purity, and how is it tested? A: Purity is ≥99.0%, determined by high-performance liquid chromatography (HPLC) area normalization. A batch COA is included with every order.

Q3: How should I store it? How long is the shelf life? A: Lyophilized powder should be stored at −20 °C or below, dry and protected from light. After reconstitution, store at 2–8 °C and use within 30 days. Shelf life is 24 months when stored as directed.

Q4: What is the MOQ and lead time? A: Standard sizes (10 mg / 50 mg / 100 mg) are in stock and ship within 1–3 business days. Custom multi-gram to multi-kilogram orders typically require 24hours
