A few years late to this one - I went off it for 7 months. Results are terrible. I had been on minoxidil (mostly the Dr. Lee stuff) and then went to Lipogaine after) finasteride off and on - but I had been doing this for almost 20 years - and as I am 64 I figured probably what I have is what I will have without spending all the money. WRONG! I have lost 75% of my hair. If you are on minoxidil `- don't quit - you may be in for a shock! P. S. - I am furious with the FDA for shutting down Dr. Lee and the others. His 15% Xandrox formula and topical finasteride was a winner. I ended up having to go to oral finasteride. It worked great. But I grew manboobs. I just can't win. Lipogaine was a good formula till they took out the Azealic Acid. I mean, it is still probably a good product, but you can buy a year supply of Kirkland minoxidil for $47 with shipping from Amazon. I am going to buy the AA flakes and make my own batches.
