TB 500 Overview

TB 500 peptide is a synthetic form of Thymosin Beta-4, a natural protein found in the body. It has various biological functions including actin binding, tissue repair, reducing inflammation, cardiovascular health and improving flexibility. Unlike peptides that focus on fat loss or muscle growth, the TB 500 peptide is mainly being researched for healing and recovery. The biological effects of TB-500, however, have not been documented. Research is ongoing and the claimed benefits are still emerging.
