For a woman who wants to avoid the side effects of stimulant based fat burners my first recommendation would be strict diet

. Failing that the anarchy stack (ALCAR + ALA + CLA) and sesathin would be an excellent choice. This is the healthiest most side effect free fat burning combination available.
I wouldn't be crying into my milk about the trimax being banned unless you wanted to watch your sister waste away all her lean mass and rebound from thyroid shutdown. I have personally found that even small doses of T3 are a disaster for cutting without concurrent use of anabolics.
