There isn't any way I can tell you what you have done to your body as we all respond differently. I can tell you that the last thing to develop is your brain. Androgens interrupt these final touches puberty bestows upon us, which includes higher reasoning and logical ability. There's also the chance that you may not recover your ability to produce hormones on your own again - ever.
Therein lies the problem that as we can't necessarily see the damage, many think it doesn't exist. Not until later, when it's too late, and nothing can be done.
I may have come across really harsh, but we've been getting quite a few folks lately that encourage AAS use in younger men - which actually damages the community because it portrays a negative image of what we are actually trying to do here. Which is to educate people BEFORE they make a mistake that can literally cost them their health down the road.
You DO have a good base, but that wasn't the drugs that got you there, it was the hard work and determination that did. I would continue to work hard and keep learning as much as you can when it comes to diet and training. I got my first Weider weight set 27 years ago, and am still learning new things everyday.
I don't think AAS is the tool you need at this point. In fact, I feel that you'll find it to be a crutch when you can still continue to grow without it. I'm wary of recommending anything but creatine (it really does work), a good multi, fish oil, and lots of good whole foods.
Imagine how much better your results could be if you had another 5-6 years of experience and training under your belt. That, and our priorities in life change as we get older - it would suck to pay the price for something you no longer have a passion for years from now.
