I bought Cialis (Tadifil?) from ADC and it is awesome! I originally went to my doctor and he prescribed me 3 pills which costs me $90 fucking dollars! So I said fuck that shit and ordered i think 90 pills that costs around $100. It took what seemed like forever to receive them because they're coming from India and they have to get through customs, but its well worth it! I still have a bunch of them left over because I used them when I first met my ex-gf because I always get so nervous and my cock won't stay hard, so this put the fear of god into her. You'll get pipe dick with these bitches AND I bite these in halves or thirds to make Viagra type pills.
For me, if I take a whole pill, it will take about 2-3 hours to kick in and it will last at least 36 hours. But I usually take a half pill and chew it up into powder so it begins to work in 30 minutes, but still lasts almost 24 hours. For me, Cialis is better than Viagra and my only side effect is a stuffy nose (not all the time) when I'm hard.
