AT 19 YOU DO NOT NEED STEROIDS, TEHY COULD DAMAGE YOU FOR LIFE AS YOU'VE NOT STOPPED DEVELOPING
You have plenty of natural test in your system. I'd concentrate on eating more and making sure your routine is right. Post them up in the appropriate forum and you'll find something wrong - trust me. If you're not growing, one of these is at fault.
If you do decide to take steroids (bad idea) then injectables put less pressure on your liver, and it's best to drink loads. ome people use milk thistle.
If you get acne then most types of gear will make it a lot lot worse. Most cycles are based around test (especially first ones) and this WILL make acne come back - trust me, I'm 27 and it makes mine come back!
You cannot ask where to get it from mate, I'd edit your post. You are now likely to get emails from people offering you juice, DO NOT ACCEPT them, they are 99% fake. If you train in the right gyms, and research enough you'll find a good source.
1. edit your post to remove source request
2. don't take steroids for a few years
