Tadalafil is incredible. I get no bad sides plus it remains active for so long. I have tried quite a few brands and most are crap. I used our one for the 1st time the other day and it wouldn't go down! Made up to find top class tadalafil but it's no surprise as everything I have tried of ours has been amazing. Balkan Cialis is top notch too. Literally all the others I have tried have been no where as good as those two.
