Peptides have been shown to potentially extend life by various mechanisms. One of the main ways they do this is by stimulating the production of growth hormone, which plays a crucial role in promoting cellular regeneration and repair. Peptides also have anti-inflammatory effects and can enhance the immune system's response to infections and diseases, thereby promoting longevity. Additionally, peptides may improve tissue elasticity and skin health, which can contribute to a youthful appearance and overall wellbeing. It's important to note, however, that more research is needed to fully understand the extent of peptides' impact on life extension.
