Hey guys, i start a course on muscle mass and endurance. I do boxing i am 23 years old my height is 180 cm and my weight is 75 kg. My plan is to move to another weight category to 81 kg. I will start with LGD-4033 on 65 days. First week i will start with 10 mg then next days with 20 mg. After the course immediately or in a few days i will start to drink GW-501516 for endurance. Will see what we get as a result.
