Core Molecular Specs & Technical Index

Pinealon peptide, also known by its systematic name Glu-Asp-Gly, is a synthetic tetrapeptide composed of three amino acids: glutamic acid, aspartic acid, and glycine. This specific sequence is designed to mimic naturally occurring neuroprotective signaling molecules. As a B2B raw material, it is typically supplied as a lyophilized white powder with a purity standard of ≥98% as determined by High-Performance Liquid Chromatography (HPLC). The molecular weight of Pinealon is approximately 319.27 g/mol, and it exhibits high water solubility, making it suitable for both injectable and oral formulations. For laboratory and manufacturing purposes, the product is recommended to be stored at -20°C in a desiccated environment to maintain stability for up to 24 months. The peptide is supplied in sterile, vacuum-sealed vials to prevent oxidation and contamination.

• Purity Grade: ≥98% (HPLC) with a maximum of 1% residual trifluoroacetic acid (TFA) content.
• Solubility Profile: Soluble in water at 10 mg/mL; also soluble in PBS (pH 7.4) for biological assays.
• Molecular Formula: C₁₂H₁₇N₃O₈ with a net charge of -2 at physiological pH.
• Stability Data: Lyophilized powder stable for 24 months at -20°C; reconstituted solution stable for 7 days at 4°C.

Industry data from the Peptide Therapeutics Foundation indicates that the global market for synthetic tetrapeptides like Pinealon is projected to grow at a compound annual growth rate (CAGR) of 8.2% from 2023 to 2026, driven by increased R&D investment in neuroprotective and anti-aging applications.

Manufacturing & Quality Control

The production of Pinealon peptide follows a standardized solid-phase peptide synthesis (SPPS) protocol using Fmoc chemistry. This method ensures high coupling efficiency and minimal racemization. After synthesis, the crude peptide is cleaved from the resin and purified using preparative HPLC with a C18 column. The final product undergoes rigorous quality control to meet pharmaceutical-grade standards. Each batch is tested for identity, purity, and potency using mass spectrometry (MS) and amino acid analysis (AAA). Third-party testing is a critical step in the supply chain, providing independent verification of the product's specifications. Certificates of Analysis (CoA) are issued for every batch, detailing the results of all tests performed.

• Production Process: Fmoc solid-phase synthesis with HBTU/HOBt activation for optimal coupling.
• Purification Method: Preparative reverse-phase HPLC with a gradient of acetonitrile in 0.1% TFA.
• Third-Party Testing: Independent lab verification for endotoxin levels (<1 EU/mg), microbial limits, and heavy metal content.
• Certification List: CoA, MSDS, and stability report provided with each shipment.
• Batch Consistency: Each batch is tested for peptide content by UV spectroscopy at 280 nm.

Commercial Application Scenarios

Pinealon peptide is primarily used in three commercial sectors: cosmetic formulation, laboratory research, and bulk wholesale distribution. In cosmetic formulations, it is incorporated into serums and creams aimed at reducing oxidative stress and improving skin mitochondrial function. The peptide is typically added at concentrations of 0.1% to 0.5% in water-based formulations. For laboratory research, Pinealon is used in cell culture studies to investigate neuroprotective mechanisms, often at concentrations ranging from 10 µM to 100 µM. Bulk wholesale buyers, such as nutraceutical manufacturers, purchase Pinealon in kilogram quantities for the production of cognitive health supplements. These supplements are formulated as oral capsules or sublingual sprays, requiring the peptide to be encapsulated with excipients like microcrystalline cellulose for stability.

• Cosmetic Formulation: Used in anti-aging creams at 0.2% concentration to enhance skin cell energy metabolism.
• Lab Research: Applied in neuronal cell models to study the reduction of reactive oxygen species (ROS).
• Bulk Wholesale: Supplied in 100g to 1kg containers for large-scale supplement production.

pinealon peptide VS Ordinary Low-Grade Peptides

Bulk Purchase Selection Guide

When sourcing pinealon peptide in bulk, buyers must navigate common pitfalls to ensure they receive a product that meets their specifications. One frequent issue is purity misrepresentation, where suppliers claim ≥98% but deliver material with significant impurities. Always request a recent CoA from the specific batch being offered, not a generic document.

Another critical factor is packaging integrity. Pinealon peptide is hygroscopic and sensitive to moisture. Reputable suppliers use vacuum-sealed, nitrogen-flushed containers with desiccant packs. Avoid suppliers who offer bulk peptide in simple plastic bags without proper sealing, as this compromises stability.

Buyer checklist for bulk purchases:

• Request batch-specific CoA with HPLC chromatogram and MS confirmation.
• Verify storage conditions during transit: cold chain for reconstituted products, ambient for lyophilized powder.
• Ask about minimum order quantities (MOQ) and lead times, typically 5-10 business days for standard orders.
• Confirm return policy for quality discrepancies, ideally with a 30-day window for testing.
• Check supplier certifications such as ISO 9001 or GMP compliance for manufacturing facilities.

Core Product Advantages

The primary advantage of high-grade pinealon peptide is its exceptional purity, which directly impacts formulation success. With ≥98% purity, formulators can predict solubility, stability, and interaction with other ingredients with high confidence. This reduces the need for extensive re-formulation and accelerates product development timelines.

Stability is another key benefit. Properly manufactured pinealon peptide maintains its integrity for up to 24 months when stored correctly, allowing bulk buyers to maintain inventory without frequent reordering. The peptide's compatibility with standard cosmetic preservatives and antioxidants further extends its utility in commercial products.

Cost performance is optimized when purchasing from established suppliers who offer tiered pricing for bulk orders. Combined with comprehensive technical support—including formulation guidance and stability data—buyers gain a reliable partner for long-term sourcing. This technical support often includes access to application notes and troubleshooting assistance, which is invaluable for new product development.
