Documentation & Quality Assurance

Each lot is sourced through our verified global supply chain with emphasis on traceability and quality control. We work diligently to obtain and maintain third-party analytical reports (HPLC/LC-MS) and Certificates of Analysis for each batch, as part of our ongoing quality process. These documents are reviewed internally and displayed as they become available. Independent third-party testing is also performed on select lots to confirm identity, purity, and alignment with our internal specifications.


Important Notice

This product is intended for laboratory research use only. It is not intended for human or veterinary use, and must not be used for diagnostic, therapeutic, or clinical purposes.
This material is not a drug, medical device, or dietary supplement, and has not been evaluated by the U.S. Food and Drug Administration.


Quality & Manufacturing

All materials are sourced from carefully vetted domestic and international manufacturing partners who follow quality systems consistent with ISO and cGMP principles. Each supplier is reviewed for reliability, documentation integrity, and transparency in testing.

We require a verified purity of 99% or higher and perform independent third-party spot testing to confirm that select lots meet our internal standards for identity, purity, and composition. Where available, endotoxin testing results are included on Certificates of Analysis to verify laboratory purity; their inclusion is for research quality assessment only and does not imply suitability for human or veterinary use.

All research materials are sealed for integrity and packaged for stability during storage and transport from manufacturing through final delivery.

Storage Instructions

All our research peptides are manufactured using a lyophilization (freeze-drying) process. This method is designed to maintain product integrity and allows vials to remain stable during shipping for approximately 3–4 months.

Once a vial is reconstituted with bacteriostatic water, it should be stored in the refrigerator to help maintain stability. Under these conditions, reconstituted material is generally considered stable for up to 30 days.

Lyophilization is a dehydration technique in which compounds are frozen and then exposed to low pressure. This causes the water in the vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure. This powder can be kept at room temperature until reconstitution.

Upon receipt, products should be stored away from heat and light. For short-term use, refrigeration at approximately 4°C (39°F) is suitable. For long-term storage (several months to years), vials may be placed in a freezer at approximately -80°C (-112°F). Freezing is the preferred method for preserving product stability over extended periods.

Thymosin Beta-4 Modulates Cardiac Remodeling by Regulating ROCK1 Expression in Adult Mammals.

International journal of molecular sciences 2025

It equally reduces scarring, however, the precise mechanisms through which the peptide assists this phenomenon have not been properly elucidated. We performed miRNA profiling on adult mice hearts following permanent coronary ligation with or without systemic TB4 injection and searched for targets and novel mechanisms through which TB4 may mitigate pathological scarring in the heart.

Inhaled exogenous thymosin beta 4 suppresses bleomycin-induced pulmonary fibrosis in mice via TGF-β1 signalling pathway.

The Journal of pharmacy and pharmacology 2025

METHODS: Pulmonary fibrosis was induced in mice with bleomycin, and rhTβ4 was administrated by nebulization following three strategies: early dosing, mid-term dosing, and late dosing. In vitro, the effects of rhTβ4 on fibroblast and lung epithelial cell phenotypes, as well as the TGF-β1 pathway, were evaluated.

Thymosin beta-4 - A potential tool in healing middle ear lesions in adult mammals.

International immunopharmacology 2023

Acute tympanic membrane perforations primarily occur due to injury or infection in humans. In acute cases, nearly 80-94 % of the perforations heal spontaneously. In chronic cases, non-surgical treatment becomes significantly limited, and the perforation can be restored only by myringoplasty. In addition to classical grafts such as the fascia or cartilage, promising results have been reported with various biological materials including silk or acellular collagen. However, despite of all the effor
