The cream used once daily is stronger than the liquid if you use the liquid once daily. Its based on my own experience. I know he said twice per day liquid of Proxiphen is about as effective as once per day of the cream but I did not want to have to use the liquid twice per day. I started on Proxiphen without using Prox-n. I went for the powerful stuff since I was hoping to ween off Propecia when I first started it. However, I decided to stay on Propecia since I don't have any life altering sides. I get periods of time where I shed more than others but recently since I switched to the cream my shedding has decreased significantly and my hair has improved too. Yes, I am getting regrowth too. But nothing I would call spectacular.
