I usually consider phentermine as a womans weight loss diet pill personally. Its going to surpress your appetite, no food = fat loss, and MUSCLE LOSS! What kind of cutting cycle are we talking about? If you wanted to run it alone for maybe 3 weeks diet and cardio your butt off, loose 12pounds, maybe more, level out for a few weeks and hit a lean mass cycle it might be effective! Im thinking that would be the better way to go than run it with AAS. Use clen, T3, or ECA.
