View brandDetailed compound information
Thymosin Beta-4 is a ubiquitous 43-amino-acid protein that binds monomeric G-actin and regulates cytoskeletal dynamics. Research models show it drives cell migration toward injury sites, upregulates VEGF-mediated angiogenesis, and modulates inflammatory cytokine profiles. Unlike BPC-157, which works best injected near the injury, TB4 operates systemically — remote injection delivers comparable effects across multiple tissue compartments.

Already setting myself a reminder to reorder before my current vial runs out so I do not miss a beat. Shipping was fast, packaging was clean, quality is consistent with the lab report. No complaints from me at all.
J'ai changé après que mon ancien fournisseur m'ait livré un produit douteux — mauvaise couleur, livraison en retard, aucune documentation. Le jour et la nuit ici. Bien scellé, numéro de lot conforme aux documents, le produit fait ce qu'il faut. Content d'avoir changé.
Research peptides are chemical reagents for laboratory analysis. Regulations vary by jurisdiction — it is the buyer's responsibility to ensure compliance with local laws. See our Terms & Conditions page for the full regulatory framework across the EU, UK, US, Switzerland, Thailand, and other major markets.
Lyophilized (unreconstituted) peptides should be stored at -20°C for long-term storage or 2-8°C (refrigerated) for short-term use. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles — aliquot into smaller portions if needed.
For laboratory research use only. Not for human consumption, diagnosis, treatment, prevention, or in-vivo administration. By purchasing you confirm you are a qualified researcher or institution.
Reconstitute the 10mg vial with 2mL bacteriostatic water slowly along the interior wall. Yields 5 mg/mL. On a U-100 insulin syringe, 20 IU = 0.2 mL = 1 mg.

Gently inject bacteriostatic water (bacteriostatic water) along the inside wall of the vial — do not spray directly onto the powder. Let it dissolve naturally or gently swirl. Never shake vigorously. Standard reconstitution: add the desired volume of bacteriostatic water based on your concentration needs. For example, 5mg peptide + 2.5ml bacteriostatic water = 2mg/ml concentration.
Yes. Every batch undergoes independent third-party HPLC (High-Performance Liquid Chromatography) and mass spectrometry analysis. We provide a Certificate of Analysis (COA) for each product, verifying identity, purity (≥99%), and the absence of contaminants. COA documents are available for download on each product page.
Yes. We offer temperature-controlled shipping to most EU and Asian countries. Standard EU delivery is 24-48 hours. International orders are shipped in discreet, professional packaging with cold-chain protection where required. Customs documentation and regulatory paperwork are provided as needed.
We currently operate on an inquiry-based ordering system. Submit your order through checkout and our team will contact you within 24 hours to confirm details and arrange payment. We are working on integrating direct payment options for a seamless experience.
A Physician's Endorsement
Quality assurance isn't a marketing claim — it's a daily decision. I choose LifeSpanSupply because every batch is independently HPLC-verified to 99% purity, fully traceable, and held to the safety standards my patients deserve.
