Or I guess to be more accurate, I've used pwo's in the past that give me the same level of pump once it kicks in, but the Cialis gives me the ability to get that same strong pump all day without having to take pwo and it happens very fast. I also do not use caffeine or other stims.
All I can contribute to the thread is Cialis is great for pumps. Haven't really used pwo's in years, so haven't tried whatever is new to the market. I used to get amazing pumps with NO-Xplode add beta-alanine/citrulline. Cialis gives me the same pump without having to drink all that. Have also used C4 and arginine+caffeine. C4 seemed good for energy but not as strong pump as NO-Xplode. Right now, Cialis is my favorite pump product. Full power pumps and increased blood flow 24/7 and nothing else.
