Key ideas from Andrew Huberman

• Nearly one in seven Americans is taking a GLP-1 drug, with 20% having tried them - potentially eradicating obesity in theory
• Retatrutide allows people to lose up to a third of their body weight with some degree of muscle sparing
• BPC-157 for tissue repair has very high LD50 with no reported adverse events despite widespread use
• Real-time cortisol monitoring would be transformative - you want a big morning peak that troughs in late afternoon
• Peptides from gray market sources are 99% purity but may contain 1% contaminants like lipopolysaccharide
• Future health tech will write to biology: cooling core body temperature through palms/feet, eye masks for sleep induction
• Melanotan raises energy and libido dramatically but skin color changes can be permanent - 'not for vacation use'
• Banking your own exercise blood for future infusions could be more beneficial than glutathione or NAD treatments
