Double roger on what DLD said above. Check out the link in my signature. Normally Viagra is over $300 for 30 pills or so. Generic is a LOT cheaper.....like $30ish for the same amount and, yes it works just as well as the "real" viagra. Same active ingredient...just no big, name brand company.
I love using it for my girth workouts...so much easier to stay at the right erection level and I get a more efficient workout. I have zero erection problems either...I just find it hard (ha ha) to stay erect enough without constantly stopping to stimulate myself...with a lot of concentration on sexually arousing things .......without the viagra. Even if I'm watching some very arousing adult entertainment. There's just no comparison to the viagra erections for girth work!
