Don't overdo it. Start with a small dose. If you plan on continuing to cycle in the future you can ramp it up little by little each cycle. Because, who knows? For whatever reason, you might decide it's not for you after the first cycle. So don't use too much too soon. But it all depends on other factors too. Such as how long you want to run them and then, of course, taking a dose that works to help you meet your specific goals.

IMO he doesn't need testosterone. He needs food and training. With that said, I believe people should be able to do what they want (in most scenarios), it's just that no amount of steroids will help him until he learns how to do those other 2 things first.
