I'm 30 years old 6'3 225lbs and want to start my first cylce. Need advice on the whole process. I want to gain about 20 more pounds. I was offered the test 300 e and need to know how much to take and when and if I need to take anything else with it. I'm not looking to get big as shit just wanna gain muscle quickly. I want to be big and cut not just a big freaking dude. What's the best diet for this as well?
