ive never used that stack or any other "stack" so i cant weigh in.
but always remember this when your using sups: food is the most powerful drug to use. so if used right it can be the awesome fat burner ur looking for.
Im not anti sups BTW! i think they are a great supplement(lol) to your weight loss plan. i just think people get too caught up with them and not focus on what matters the most:your diet.
