Peter evaluates longevity drugs, aspirin for CVD, & strategies to improve muscle (AMA 76 sneak peek)

In this “Ask Me Anything” (AMA) episode, Peter revisits the “proven, promising, fuzzy, noise, nonsense” scale and applies it to a variety of popular topics. He begins with a refresher on what each category represents before classifying a range of interventions based on the strength of their supporting evidence. The conversation spans three main areas: drugs for geroprotection (including GLP-1 receptor agonists, SGLT2 inhibitors, methylene blue, and telomere-lengthening supplements), the use of low-dose aspirin for cardiovascular disease prevention, and strategies to improve muscle mass through optimal protein intake and follistatin gene therapy. This episode provides a clear, evidence-based overview for listeners seeking to understand where these popular health and longevity interventions stand on the spectrum of scientific credibility.
