In the second tier sit peptides like Thymosin Alpha-1, which have regulatory approval for specific indications, meaningful human trial data, and plausible longevity mechanisms even if their specific application to healthy aging remains to be formally tested
Common causes include contaminated vial stoppers (not swabbed with alcohol before drawing), exposure to temperature extremes, or inadvertent shaking
In addition, the peptide supports glycosaminoglycan synthesis, including hyaluronic acid, which improves hydration and barrier function
It plays crucial roles in cell migration, tissue regeneration, and inflammation modulation
