TB-500 Overview
TB-500 is a synthetic peptide based on thymosin beta-4, a protein associated with cellular migration, wound healing, and anti-inflammatory activity. In research contexts, TB-500 is commonly used to explore potential effects on tissue repair and recovery.
- Peptide Length: Larger peptide derived from the full thymosin beta-4 sequence
- Research Stage: Primarily animal studies and in vitro experiments
- Theoretical Effects: May influence cell migration, inflammation, and tissue repair mechanisms
- Human Data: Limited to no high-quality clinical studies; primarily used in laboratory research

TB-500 Fragment (17-23) Overview
TB-500 Frag (17-23) is a short peptide fragment derived from TB-500. Researchers often isolate shorter sequences to study specific active regions of a protein, aiming to identify minimal sequences responsible for biological activity.
- Peptide Length: Smaller, focused fragment of the TB-500 sequence
- Research Stage: Early-stage, cell or animal studies only
- Theoretical Effects: May replicate certain TB-500 actions with potentially more targeted activity
- Human Data: No verified studies; safety and efficacy in humans remain unknown
Fragment studies are used to explore biochemical mechanisms in controlled laboratory experiments rather than applied human use.
