I'm gonna give you some advice and not jerk you around so if you want to be coddled and pet then don't read this post.
look kid when i was 19 i was worried about my job, trying to get laid as much as possible and college.
you've got this shit in your head and you are gonna do something stupid out of ignorance. nothing needs to be done.. if you want to boost your levels then run a natty supp as jb has said.. thats all.. stop messing around with your hormones.
also your first post makes no sense. if you were sold deca or watered down test your T levels wouldn't be 7 and why the fuck would a source sell someone deca instead of test, its not like there is a price difference where he would make money selling you deca and not test lol.. they would be much higher. you have a lot to learn about hormone use and your doctor is a moron.. combine those 2 facts and you have a disaster which is commencing.
and please stop argueing with everyone on here.. you don't know shit about what you are talking about and we all have centuries of experience so why do you keep argueing and posting studies like you are some sort of expert? just STFU and listen to advice from people who have been there and done that.
if you want help with your diet go to the diet section.. injecting testosterone isn't gonna solve that problem either
