You posted this an the anabolic section as well, and even though some of those guys were a lil harsh, they were right. Testosterone is not a toy, nor is it a magic bullet that you inject and swell up like hulk. There are many factors you need to be aware of and precautions that should be taken. Without a good training program and having a diet tailored to muscle growth, test isn't going to do a thing for you.
Hit the gym harder, increase your protein to atleast 200-250 grams a day, and increase your calories. You'll see way better results doing that than you will using test with no foundation built up.
