i have used it. it worked good for me. b careful of dosing, i think its 200mcg per ml, so you have to use half a ml for 100mcg and less then that if you are ramping up. i like a dumb @ss didnt pay attention first time i used it and started out at 1ml. man i was stark white and heart was beating like a race horse. guess we all learn our lessons lol... just check the dosing on it
