TB-500 5mg Dosage & Mixing Guide

TL;DR

TB-500 is a synthetic fragment of the naturally occurring protein thymosin beta-4, studied for tissue repair and recovery. Its evidence base is almost entirely preclinical, drawn from animal and laboratory models, with no established human trials. It is a research compound for laboratory investigation and educational reference only, not therapeutic use.

What is TB-500?

TB-500 is a synthetic peptide fragment of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino acid protein found in nearly all human cells. TB-500 consists of the active region of the full Thymosin Beta-4 molecule.

Thymosin Beta-4 plays a key role in actin regulation, cell migration, and tissue repair processes. Research has investigated its effects on wound healing, inflammation modulation, and various tissue regeneration applications.

The peptide’s mechanism centers on its interaction with actin, the protein responsible for cell structure and movement, which is essential for tissue repair processes.

Common Dose Calculations

Desired Dose	Draw Volume	Syringe Units
2.0mg	0.80mL	80 units
2.5mg	1.00mL	100 units
5.0mg	2.00mL	Full vial

Suggested Research Protocol

Loading Phase (Weeks 1-4):

Dose: 2-2.5mg
Frequency: 2x weekly
Total weekly: 4-5mg

Maintenance Phase (Weeks 5-8+):

Dose: 2-2.5mg
Frequency: 1x weekly
Total weekly: 2-2.5mg

Protocol Notes:

Loading phase establishes systemic levels
Can be used in conjunction with BPC-157 in research
Some protocols use higher loading doses (5mg 2x weekly)

Injection Guide

Subcutaneous Administration

TB-500 is typically administered subcutaneously:

Clean injection site with alcohol
