What is TB-500 and what is Tesamorelin?
TB-500 is classified as Thymosin β4 fragment · tissue-repair research; Tesamorelin as Synthetic GHRH analog · secretagogue research. Both profiles below cover scientific identity only — what the molecule is and which laboratory models it appears in. Verve supplies both strictly as in-vitro reference materials, and neither profile describes human or veterinary use.
TB-500
Thymosin β4 fragment · tissue-repair research
TB-500 is a synthetic 43-amino-acid peptide corresponding to an active fragment of thymosin beta-4, a naturally-occurring actin-binding protein. Verve supplies it as a high-purity research compound for tissue-repair and cellular research.
