if its your first cycle then you will see SIGNIFICANT gains on 300 MG's a week. Most people say to start with 500. I disagree with this for a few reasons. One reason is that 300 mg a week is actually ALLOT and like I said before, if its your first cycle, youll see awesome gains. second reason is that if you start at 500, then you almost have to stay there or go up from there on your next cycle. if you start at 300, youll gain as much as you can on 300 then when you run your next cycle, you can maybe start at 500 and gain even more than you did from 300, so your gains will be more consistent. plus it will probably be easier to regulate E2 starting at 300 a week. itll give your body a good sense of how it handles test without dosing it too high and having bad side effects. I still run 300 mgs of test when I stack it with other compounds. But, like HGH.TO said, gains are made in the kitchen. 90% of your gains will be from how and what you eat. You will NEED a good meal program. lots of rest, lots of WATER and OTC supplements to help protect your organs. especially if youre using orals.
