It's commonly used in bodybuilding competitions.

Now I cannot get that picture out of my head. A crowd full of bodybuilders in tight shorts and all on Viagra doing workouts. Each to his own I guess..

I don't know how people imagine viagra working - it's not like you take a pill, you continue browsing the internet, reading news, and suddenly, a boner lifts your desk.

It is being used off label all over the place for heart conditions. That’s why i take it. The on label use is actually pretty annoying for the first few months.

Not trying to be crass here, but does that mean you are just walking around with boners all day?

you know what else would? walkable cities more time off from work more third spaces less air pollution less inequality of course none of that "increases productivity or GDP" so the ruling class won't consider it. of course when they start dying like Japan with low birth rates, their 'solution' is to have a government funded dating app instead of doing the obvious.

Given the opportunity, people will do anything else than have more than 2 children, which is the requirement to increase the population. There’s just better stuff to do than spend multiple years taking care of the baby. Any argument other than “for the greater good” won’t sound reasonable to educated population. Talking to my friends, especially women who already have a child, they keep mentioning the opportunity los…

For me having kids has been massive personal growth. In some ways having kids is synergistic with many of life’s goals and personal growth. Career, less so, but I can a more capable human for being a parent.

It also seems to cause melanoma, so... Pomergranate/beetroot/garlic seem safer. Arginine/citrulline perhaps as well (all of them increase NO in the blood).

"In 2014, a study published in JAMA Internal Medicine found that the use of sildenafil, more commonly known by its brand name Viagra, within 3 months prior to the study’s start increased the likelihood of developing melanoma by as much as 84 percent.'

It is associated with increased risk of melanoma, but not known to cause it. The third variable is expected to be lifestyle / socioeconomic. https://jamanetwork.com/journals/jama/fullarticle/2338254

> Men taking PDE5 inhibitors had a higher educational level and annual income, factors that were also significantly associated with melanoma risk.

Still, it's a food for thought. I know correlation is not causation but there might be some link that hits some folks unexpectedly hard. I was taking sildenafil to improve brain hypoperfusion from long covid and one day a fast growing mole appeared on my arm that reached 2cm diameter in a few days - the suspicion was on nodular melanoma or pyogenic granuloma and it turned out to be the latter. I stopped taking sildenafil immediately. I am in the socioeconomic group they mentioned.

> The OxHARP trial was a meticulously designed double-blind, placebo-controlled study involving 75 participants who had experienced a minor stroke and showed signs of mild to moderate small vessel disease. Each participant received sildenafil, a placebo, and cilostazol (a similar drug) over three-week periods in a randomised order. I feel like dudes will know if they got Viagra or not? It doesn't seem like cilostazol…

Viagra doesn't work for everyone; it's not like you take it an get automatically erect, even with sexual stimulus. There are many reasons for ED, some of them in the brain, some of them in hormones. Viagra only helps with cardiovascular ones.

That's pretty much how I imagined it working.

Was news to me to read in a sibling that it also requires mental stimulation. I thought it was purely a physical inducement by the drug, as many drugs for other purposes induce a physical response without requiring mental effort.
