Personally I don't see the reason the use a compound unless you have done all the work prior to cycle to really reap the rewards of what it offers. For instance, masteron is noted for increasing muscle hardness, but as stated, this is only evident when your bodyfat is low. Contrary to popular belief, it (or anything else) won't take you from 15% BF down to 7%. At 15% you might see SOME benefit, like toning, but the main benefit that makes masteron so popular wont' be noticed at that BF % level. So really, why bother to take it? You would see minimum strength gains, but if you are using test, you are going to see those anyway.
Always choose tools - whether it be AAS, or diet, or training programs, etc.. - that will get you from Point A (where you are now) to Point B (where you want to be.) Don't select tools that are only going to be effective once (if) you reach Point B.
