So my wife is in hunt for new fat burner/ stack combo? She has good eating habits (although too low of cals sometimes) and hits gym 3 to 5 days a week and she will start buckling down harder in a few weeks after her job gets back to routine. She is 5 foot and runs about 115 lbs and is looking to hit about 108 while having good body composition. She does a mix of weight training and cardio now we were just wondering a good stack to help her along with the journey.. She is pretty stim tolerant and we were wondering if some good stack combos out there that you guys or ladies could comment about?
