AG Cialis is awesome. I got horrible back pains when I first tried it, thought I was catching the worst flu ever. #1, After I used it 3+ times, the pain went away almost completely. #2, yeah I think I ODed on it,lol. My dropper would only fill up half way, even when just opened, so I was told that 2.5 droppers equaled one good full dose. I will say that cialis is mindblowing. I never really have had a problem achieving an erection anyways but this stuff is fantastic. after one dose, Im good to be rock hard, anytime, instantly for 48 hours, no matter how many times I have sex. Ive had sex 4 times in one day, with no lag, because of this stuff. Cialis is pimp juice in a dropper,lol. AG Viagra is cool too. I only tried it because it was my "free" bottle. Same or better erections as cialis, but gets into your system much faster. My rules is to take cialis on Friday night, then fuck all weekend. If I want an extra push mid week, go viagra. Two droppers, held under the tongue will produce excellent results in like 10 minutes.
