I'm shooting it... seems fine even though it irritates a little after injection... stings a bit, but I'm used to it. I thought I was having a reaction from it like heart palpatations, but they were actually stress induced. The hardest thing was starting with it....I mean WTH?... what is this stuff going to do to me?... So far I have no more sudden fainting and dizzy spells...I'm riding my bike again so seems it's doing well for me.
