Full-length thymosin beta-4 vs TB-500: the distinction that matters
Research & educational use only. This content is not medical advice. Consult a qualified healthcare professional before using any peptide compound.
This distinction gets blurred constantly. Full-length thymosin beta-4 is the 43-amino-acid peptide that has actually entered early human clinical trials for things like dry eye and wound healing. TB-500 is a fragment marketed in research-chemical channels.
When people cite the thymosin beta-4 human trials to justify TB-500, they are conflating two different molecules. The full-length human data should not be transferred wholesale to the fragment.
