it works?

Yes it works (for me anyway). But I take 6 pills a day. When I took 4 pills a day it didn't work, but maybe I was just impatient and should have waited some time.

I'm takin it since 5 days...yesterday and today i took 6 pills a day but tonight I had no erection...really bad

Are you trying to fix low libido or erectile dydfunction. Personally I have found these helping with libido but I believe that's all it does. You can't fix erectile problems with these pills.
