Every vial of TB-500 is manufactured using solid-phase peptide synthesis (SPPS), verified by HPLC purity analysis and mass spectrometry, and accompanied by a published Certificate of Analysis (COA). Typical delivery to California is 1–3 business days after order confirmation.

TB-500: Research Background

Mechanism of Action: TB-500 is a synthetic fragment of Thymosin Beta-4 (Tβ4), specifically the actin-binding domain. It promotes cellular migration, angiogenesis, and reduces inflammation through upregulation of actin polymerization and metalloproteinase modulation.

Research Applications: Muscle, tendon, and cardiac tissue repair. Promotes blood vessel formation (angiogenesis), reduces inflammation, and accelerates wound healing in preclinical models.

Published Research: Research includes cardiac repair studies (Smart et al., 2007), skeletal muscle regeneration (Sopko et al., 2011), and dermal wound healing (Philp et al., 2004) on PubMed.

Storage & Reconstitution

Storage: Store lyophilized powder at -20°C. Reconstituted solution stable at 4°C for up to 28 days.

Reconstitution Protocol: Add 2ml bacteriostatic water to 10mg vial. Inject slowly, swirl gently to dissolve.
