question about ibe's xlean

[maffucci1984@yahoo.com]

i have recently started an oxodrol pro cycle. i got all my pct supps. in order, but i have been hearing about xlean by ibe and lean extreme by another company. what exactly are these supps for in a pct? are they only used for pct if you are doing a bulking cycle where you may put on excess bodyfat? i'll probly buy one if they are of any benefit to me. but if all they do is burn fat, they are not necessary.
