I agree with @stevesmi - a good beginning and a balance point for you would be SARMS. They will give you quite an enhancement (not as much as steroids, but still very much noticeable), but they do not have all the side effects associated to steroid use, and they require a very very mild PCT. So it would be a good starting point. If you will see that these are enough for you, you can stick to them. If you will see that you want more, then you can consider using steroids.
