I've only gone for the 25mg pills, just curious. I'll probably try out Cialis too, although the duration is probably off putting.
the duration on cialis shouldnt be offputting. there is no erection on either chemical if there is no stimulation. so, though you may have taken cialis yesterday, you wont have an erection today unless you want one / feel stimulated.
personally, ive used cialis and viagra and levitra, and they all work for what they're supposed to do, but with different effects profile.
levitra is shortlived like viagra, and more or less the same in side effects.
viagra, the brand name, is always a good buy and reliable. 50mg will work 90% of the time, unless you re too stimmed, and even then 100mg will have you sorted, at the expense of a soaring head, red faces/eyes and blue vision. 100mg and speed will put your heart on edge though so be careful.
kamagra and generics will work just as well, but for some reason they always give me more in the way of side effects, due i suppose to an increase in dosage/pill?? no idea, but 100mg of kamagra felt rougher than 100mg viagra.
cialis, 10 mg will give you a stress free weekend (36h) regarding erections with minimal side effects. 20mg even more so, but with side effects which may include, annoyingly, back aches. no blue vision or red faces on this one. also works with a bit of alcohol in you (1 glass of wine eh).
so, my recommendation, if its just for funsies and to try out, go for 25mg viagra, or 50mg viagra. if its for a long weekend with your girl/hand, 10mg cialis might be cheaper. if stimmed out and needing 4h of secsy times, 100mg viagra will do it but be careful with this one due to the mentioned heart strain.
interestingly, tadalafil (cialis) is currently prescribed for prostatic hyperplasia, and in theory could help with the peeing difficulty some experience on stim use

just dont do 20mg for that effect eh
