I've taken Viagra with Cialis pre workout and it's a great pump. No I'm not all bricked up at the gym either. Now when I'm in bed with a partner is hard as a rock though. I don't want to make these drugs ineffective so I just use 5mg Cialis daily am pre workout. I'll use some Viagra and Cialis together if I was gonna hookup with some strange or if I have a special night with a partner. I'm convinced The whole "if you experience an erection lasting more than 6 hours" stuff was just a Viagra sales pitch.
