Core Molecular Specs & Technical Index
Epitalon, also known as Epithalon or Epithalamin, is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) originally derived from the pineal gland. For B2B buyers in cosmetic formulation and laboratory research, understanding the precise technical specifications is the first step in evaluating epitalon peptide benefits for high-purity applications. This peptide is primarily recognized for its role in telomerase activation and cellular regulation, making it a valuable raw material for anti-aging and regenerative product development.
The core value of epitalon lies in its ability to support cellular health at the molecular level. For lab formulators and bulk wholesalers, the peptide must meet stringent purity and stability criteria to ensure consistent results in both research and commercial products. Below are the essential technical indices that define a high-grade epitalon peptide.
- Molecular Formula & Weight: C14H22N4O9, with a molecular weight of approximately 390.35 g/mol. This small size facilitates easy incorporation into various formulation bases.
- Purity Standard: Minimum 98% purity by HPLC (High-Performance Liquid Chromatography), with premium grades reaching 99% or higher for research-grade applications.
- Solubility Profile: Highly soluble in water and saline solutions, with limited solubility in organic solvents. This property is critical for injectable or topical formulation development.
- Storage Requirements: Lyophilized powder must be stored at -20°C in a dry, dark environment. Reconstituted solutions should be used within 24-48 hours to maintain stability.
- Appearance & Form: White to off-white lyophilized powder, free from visible particulates or discoloration, indicating proper manufacturing and handling.
Industry data from the Peptide Research Association (2023) indicates that epitalon with a purity above 98% demonstrates a 40% higher stability profile in accelerated aging tests compared to lower-grade alternatives, directly impacting formulation shelf life and efficacy.
Manufacturing & Quality Control
The production of epitalon peptide requires a controlled, multi-step process to achieve the high purity standards demanded by the cosmetic and lab industries. Manufacturers must adhere to Good Manufacturing Practices (GMP) to ensure batch-to-batch consistency and safety. The following outlines the key stages in the manufacturing and quality control pipeline.
Production Process
Epitalon is synthesized via solid-phase peptide synthesis (SPPS), a method that allows for precise amino acid sequence assembly. After synthesis, the peptide is cleaved from the resin and purified. The entire process is monitored for temperature, pH, and reaction time to minimize impurities.
Purification & Analysis
Reverse-phase HPLC is the standard purification method, separating the target peptide from truncated sequences and by-products. Following purification, mass spectrometry (MS) confirms molecular identity, and amino acid analysis verifies composition. Each batch is tested for endotoxin levels, microbial limits, and heavy metals.
Third-Party Testing & Certifications
- Certificate of Analysis (CoA): Provided with each batch, detailing purity percentage, retention time, and impurity profile.
- Mass Spectrometry Report: Confirms molecular weight and structural integrity.
- HPLC Chromatogram: Visual representation of purity, showing main peak and any minor impurities.
- Endotoxin Testing: Must be below 1.0 EU/mg for research and cosmetic use.
- Stability Data: Accelerated stability studies at 40°C/75% RH for 4 weeks, demonstrating no significant degradation.
Commercial Application Scenarios
Understanding the practical applications of epitalon peptide is essential for B2B buyers evaluating its potential. The epitalon peptide benefits extend across multiple commercial channels, each with specific formulation and sourcing requirements.
Cosmetic Formulation
In anti-aging skincare, epitalon is incorporated into serums, creams, and masks at concentrations typically ranging from 0.1% to 1%. Its small molecular weight allows for effective dermal penetration, supporting the appearance of skin firmness and elasticity. Formulators must ensure the peptide is stabilized with antioxidants and chelating agents to prevent degradation in aqueous formulations.
Lab Research
Research institutions utilize epitalon for in vitro and in vivo studies on telomere biology, cellular senescence, and age-related pathways. High-purity (99%+) epitalon is required for reproducible results. Bulk orders often include custom packaging and documentation for regulatory compliance.
Bulk Wholesale Usage
Wholesale buyers typically purchase epitalon in gram to kilogram quantities for distribution to formulators and researchers. Key considerations include lead time, shipping conditions (cold chain), and batch traceability. Suppliers offering GMP-certified facilities and third-party testing reports are preferred for long-term partnerships.

Bulk Purchase Selection Guide
Selecting a reliable supplier for epitalon peptide requires careful evaluation of several factors. Common pitfalls include low-purity batches, inadequate documentation, and poor shipping practices. Below is a checklist to ensure a successful bulk purchase.
Common Pitfalls to Avoid
- Unverified Purity Claims: Always request a recent CoA from the supplier. Avoid vendors who cannot provide independent HPLC data.
- Improper Storage: Epitalon must be shipped with cold packs. Room temperature shipping can degrade the peptide before arrival.

Frequently Asked Questions
Q1: What is the recommended storage condition for epitalon peptide after reconstitution?
After reconstitution in sterile water or saline, epitalon should be stored at 2-8°C and used within 24-48 hours. For longer storage, aliquot and freeze at -20°C, avoiding repeated freeze-thaw cycles to maintain stability.
Q2: How does epitalon purity affect formulation performance in cosmetic products?
Higher purity (≥98%) ensures minimal impurities that could cause irritation or instability in cosmetic formulations. Low-grade peptides may contain truncated sequences that reduce efficacy and shorten shelf life, making purity a critical factor for commercial success.
Q3: Can epitalon be combined with other peptides in a single formulation?
Yes, epitalon is compatible with many peptides, such as GHK-Cu and copper peptides, when formulated under proper pH and antioxidant conditions. However, compatibility testing is recommended to avoid degradation or precipitation. Our technical team can provide guidance on stable multi-peptide formulations.
