Wow, I had the worst muscle ache in my legs ( could barely bend over), serious head aches through out the day, my back, that god it’s over e.t.c. I bought cialis in bulk, now I got to try and see if a 2.5mg dosage will work. Even on 20mg my erections were same as without it. For some reason my body like to reject drugs, maybe the dosage was too high. If it doesn’t work, arginine will have to be my weekend cialis.
