I'm about to start taking some antipsychotic meds tomorrow (Olanzapine). I've been off my bipolar meds for a long time. Anyway, every time I take antipsychotics, I gain a ridiculous amount of muscle really fast. This one time, I gained an average of a pound/day for about a month (I gained 30lb), and I didn't see any visible increase in fat. My bench press went from 175lb to 235lb, squat from 185lb to 295lb, and deadlift from 275lb to 365lb (all in that one month). I wasn't even eating that much, and I wasn't eating healthy at all. It was pretty cool.
Has anyone else had this experience with any medications?
