The weirdest thing I read about was weightlifters taking viagra to increase their blood flow when working out at the gym. Hopefully they shower at home.
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.
While Taladafil does not have a psychotropic effet (like Extacy, MDMA etc.), just the friction of your sport clothes may be a problem for your "experience", and visiting the sauna afterwards will be very likely somehow problematic if sauna guests match your preferences, to put it in a diplomatic way ;-)
Another thing is that overtime your body adjusts to the side effects. I used to get headaches or stuffy nose, those are gone now.
In any case, always take medication under the guidance of a doctor and don't mess with the dosage!
My sentence was never about "use Taladafil to get stronger in the Gym" but more about "do not drop it before you are going to the Gym" ;-)
Apart from that: Effects after Taladafil on your "back pain reception" my be included, as it has an effect on especially skeleton muscles etc.
The weightlifting community moved off of Viagra years ago due to Cialis having a much longer half life.
