Building muscle mass

I am 56, 5'7"1/2 , weigh 140, with a muscle mass of 116.2 lb. What is the most effective way to increase muscle mass? What are your thoughts on peptide supplements, thanks!

The longevity implications of antidepressant drugs

How might antidepressants (e.g., SSRIs) either enhance or detract from longevity? Presumably, a chronic lowering of cortisol would be amazing, but I’ve also seen a study suggesting that sertraline increased insulin in patients so maybe the issue is more complicated than we thought (who knew!).

PRP and Stem cell Progress

I do not have a specific question, I actually have many, but I would love to hear a deep dive in the current status of this research.

“The kitchen sink”

Dear Peter and team, I would be very grateful for any enlightenment on which part of “the kitchen sink” might actually works. I wouldn’t have thought either former President Trump or Joe Rogan would fare so well with Covid, but both seem to have bounced back remarkably. (Aware of the flaws with n=2, of course!) Thank you.

Eggs, cholesterol and plaque

Are there any long term health risks from eating 4 eggs a day, 4-6x per week?
