Proponents say peptides offer significant effects against aging, while skeptical scientists say these claims outpace the evidence.

Peter Fedichev’s Physics-Based Approach to Aging: A New Longevity Framework

Peter Fedichev describes aging as a three-variable system of stress (from physical, psychological, or molecular stressors), noise (small random biological fluctuations), and damage (cumulative wear-and-tear).

Peter Fedichev has proposed a physics-based framework for aging, encompassing stress, noise (small random biological fluctuations), and damage (cumulative wear-and-tear).
