It will definitely help with weight loss, but you would not be losing only fat - lean mass will also get lost along the way. Besides, at the dosages needed for fat loss it will surely cause a lot of side effects, so I would rather stay away from it if you want to lean out. There are much better alternatives that will not cause side effects, will be more effective, and will give more long lasting results. For example, SR9009 and Cardarine GW will burn fat, while maintaining your lean mass, and they will not cause any side effects at all. Besides, they will give you a drastic improvement in endurance, and will give more long lasting results.
