Agree with LL. Talk to your urologist, get a prescription, and get it filled at HEB. So much cheaper, and quicker, than the online stuff. You can also do an online consult with a doctor for a prescription; you can do that for about 30 bucks.
I heartily agree with LL and Tiger. Decline allowing anyone from being able to be informed and the doctor cannot <by law, share the information. That way you know that you are getting the right medication.
I have a personal plug in the hood for Cialis. 10 a pill for 20 milligrams which is probably more expensive than a prescription. Then there is a store by my apartment, convenience store that sells them for 13 a pill. Both probably more expensive than going through a doctor but I'm lazy and my primary care physician is an attractive lady. I do my best to come off as studly and virile during our annual physical examination so having the conversation that I want to keep fucking for an hour straight, nut, then still be hard and keep going is hard at best for me. For now the 10 dollar dick pills from my friend in the hood suffices. It's like tipping the bathroom guy 20 dollars for a condom at the Ritz knowing you are about to give the lady 400-600
wow 20 mg is a LOT to take. I get 10MG tablets and cut them in half. 5 mg is plenty to do the job for me provided I take it about 3 hours ahead of time, or better yet just take one each night before I sleep, it builds up in the body and you will have no problems with erections.
