Just an FYI, these drugs don't actually cause erections or sexual excitement. They simply make erections easier.

Now, if someon is mildly excited by other bodybuilders but usually not enough to make it known, yes Cialis could cause 'movement' as George Costanza put it.

But if you're not into what's in front of you, Cialis isn't going to change anything.

L-Citrulline supplements are also commonly used.

>weightlifters taking viagra to increase their blood flow when working out at the gym

The weightlifting community moved off of Viagra years ago due to Cialis having a much longer half life.

It’s the hardcore version of beet juice powder, which athletes often take to…increase blood flow. As a user, I can’t say whether it helps with Viagra’s advertised purpose.

If that's the weirdest thing you've heard of weightlifters doing, you are lucky.
