Clenbuterol is definitely a bad idea, especially if she wants to keep her lean mass. Let us not forget that such compounds as clenbuterol, albuterol, ephedrine and T3/4 were never meant for fat loss, and at the dosages needed for fat loss they cause a lot of trouble. Another negative aspect of these compounds is that they will also burn lean mass, not only fat, which is not a good thing before a contest. Therefore, it is best to use compounds that were specifically developed for recomp and fat loss. For instance, the above mentioned Ostarine MK-2866 will do a great fat loss job without any side effects at all. Also, the stack of Cardarine GW-501516 and N2Slin work great, and I have seen many times how it made great changes when the wife of a friend of mine cycled with it.
