If it is the stuff you and I talked about, it is called Arson by Muscle Asylum Project. It comes in what looks like a huge prescription bottle and the pills are green and black. Arsenic is rat poison.
I am currently using it, have noticed better work outs, losing fat and having much better cardio. I think I'm at about 6-9 lbs lost and am about 2/3rds through with my bottle. My friend that reccomended it lost 20 lbs in 30 days and says it was pretty much all fat.
What I like best about it is that I don't feel all "cracked out" when I am on it like other supplements I have tried. Also, I tried Clen and absolutely hated it. I was sweating and felt like I was going to die, and felt super cracked out. I still have a half a bottle and will never touch the shit again.
Arson so far gets my top approval for fat-burner.
Also, Ifight, if you are looking to add to your bench, or for anyone who lifts, Gakic is awesome.
