Buying Thymosin Alpha-1 safely

Always ask for a batch-specific Certificate of Analysis (COA) covering purity (HPLC) and identity (mass spec), and favour suppliers with independent, third-party testing and transparent shipping and return policies. Research peptides may be regulated where you live — you are responsible for complying with local laws.
