Thought id share some results.
I started propecia around mid May or so (between 15th and 20th)
The first two pics are from 6-3-2012 when I was at the height of my shed/loss. The next two pics are from today.
I started with a 30 pill (30 days) supply of propecia, and was taking 1MG pill per day. After shedding tons and having slight sexual sides, I went to 1/2 pill a day or less. I just refilled another 30 pill supply today, but have 1 last pill to chop up from my last batch.
Typically I will take either 1/2 a day, sometimes a 1/3rd, and some days even just 1/4th.. It just depends on how I cut the pill with my steak knife lol. I guess that doesn't help much as far as figuring out a perfect dose, but since I decided to reduce my dose, I have never taken more than 1/2 a pill, and I have never taken less than a 1/4th.
I also use rogaine foam before bed at night. Sometimes twice a day if I get a chance to go home on lunch or if I know I'm doing something that night.. Also Nizoral EOD and also biotin daily and a multivitamin.
The hair is roughly the same length in each photo, might have been slightly longer in the first two, but obviously I think there has been a pretty good improvement so far and hopefully I will continue to see more results.
