Welcome to the board mate!
Sounds like you need to do more learning. first of all, not knowing your BF%, saying somewhere between 15 and 20% is only guessing. The solution is to pry open that dusty wallet of yours and kick out the $20 for a set of BF calipers. this is the set me and my son got
Accu-Measure Fitness 3000
the main benefit, besides cost and qualtiy, is that this is one of the few sets where you can easily check yourself.
Next, you need to familarize yourself with the RISKS (not just benefits) of taking drugs to try to gain muscle. Read this:

now here's the part where I try to scare some sense into you...
by taking steroids now, you run the risk, a real risk of developing the following symptoms:
limp dik
low libido (not interested in fukking your woman)
high blood pressure
high cholestoral
depression
AND you run the risk of shutting down your natural test production early in life, requiring hormone therapy.
Mate, these are all old man's diseases. I was just talking to a bloke in another thread that started taking steroids at 18, now he's 30. He's gained alot of weight, not interested in sex, physical strength is gone. Why would you want to take a chance like this when you don't have to? Your body is still increasing it's natural test production!
Steroids are the last thing to consider. how's the diet? Why don't you go to the diet section and post your diet.
Bet Gbrice will be able to really take a good look and show you some opportunities for improvement.
Speaking of diet, know anything about Macros and why they are import? No? then read this:

Not too many will disagree that if your diet isn't dialed in, and you are not consuming enough food, you will not gain, regardless of whether you are taking steroids or not.
Take some time, read the material I've given you, then come back if you have any questions.
Fair enough?
