Used it and liked it... I do NOT reccommend the 1mg/day loading phase. That is too much any your chances of hyperpigmentation (lips can spot and turn purple, new moles and freckles), in my opinon from my experience, skyrocket when you go from a .5 shot to a 1mg shot. During loading I start the first four days at .5mg/day, then alternate from . 5 to .7mg per day... I did it as kind of a shits and giggles thing, I have gotten a couple new freckles from using it, but generally anything that it causes goes away when I stop use. I would reccomend it, but go easy and take your time...
