There are many supplements out there that are said to build muscle in a weeks time etc. Dont buy into that. Primarily you need to focus on your meal plan, but there are great supplements out there to boost the recovery process. My favorites are from BSN. Syntha 6 Isolate is loaded with high protein with low fats and carbs which is great for repairing broken down muscle tissue and promoting lean gains. BSN Amino X is a proprietary blend of amino acids that are vital for muscle growth and repair. BSN cell mass is a great recovery agent loaded with creatine and glutamine as well.
