I had great results on it. Did it for the last two summers. I have freckles and pale my whole life and this stuff got me a nice tan, alot of people said i looked great. i never got sick from it either or any of the boners. I started at .25mg a day for the first 10 days then up to .50mg a day for about a month (I'm very pale lol). After that I just did a .5 injection 2-3 times a week. really loved the stuff, didnt get any moles either.
