I've given it it's last chance. I will not use this crap again, at least not untill I start hearing better news about it. My first run was with the 50ml jug & it hurt like a bitch the entire cycle. This time I used 10's & mixed it with deca300 the pain was conciderably less most of the time. But, it may just be my body reacting to it, I have a few friends that have no probs at all & another that has pain so bad, he quit after a few injections. My problem more so than the pain is the knots it leaves. It acts as if something builds up or the oil doesn't absorb well or something. I was doing injections E3D going quad, quad, glute, glute & after 2 or 3 injections in each I had knots that wouldn't & still haven't gone away. They are slowly shrinking but, they are still there. The ones on my glutes when I asperate I draw light colored blood. So on my last two injections I am doing delts for the first time, it feels like someone hit me in the shoulder with a baseball bat! & that was only 1cc. I'm certain the knots aren't infection & I don't believe they are true abcess because they go away. It's not the first time I've gotten them from QV250. I'm thinking maybe oil abcess (from what I've read) they just take a while to absorb & go away. Bottom line is, I wont be using it again. I'll go back to Tornell even if I have to inject a little more or more often. Just my experience & my $.02
