Anti aging / biohacking links, etc

Anyone use tadalfil for potential cardiovascular health benefits ((ED discussion here)? I’ve read about the potential benefits and looked over some studies, and there appears to be a strong cardio benefit correlation for those using it for ED (there are a LOT of confounding factors there) - anyone seen any discussion for those not needing it for ED? Bro science also suggests benefits in the gym. Anyone using it? Anything of note to be aware of?
