Hey SB, I actually would go for the N2Burn and N2Flame, It enhanced my mood greatly without giving me jitters and it suppressed my appetite well.
Forged burner really killed my appetite as well and helped my GF with her appetite, but there has been some people saying that girls hadnt enjoyed the forged burner as much due to emotional sides etc.
I guess it would really depend on the girl. N2burn and N2flame would be my suggestion (or the N2Shred stack).
If she is looking for a pure appetite suppressant than Forged burner may also be the way to go, But may actually end up causing a few unwanted sides for her.
I hope I could help. I do not know many females who have taken N2burn or N2 flame but I would assume it would be a good stack for them.
