What Thymosin Alpha-1 Is
Thymosin Alpha-1 is a peptide the thymus makes that helps regulate immune function; approved in several countries, not the US. It is taken as a subcutaneous injection two to three times a week, and most people notice it in gradual, weeks.
What Glutathione Is
Glutathione is the body's main antioxidant, injected because the oral form is poorly absorbed. It is taken as a subcutaneous injection twice a week, or a $90 nurse-given shot, and most people notice it in 4 to 8 weeks for skin.
