care to explain a little?
like only 2-3 small test only cycles per year?
Look, if you go above your genetic max, come off and your hormone levels normalize, you will gradually lose muscle until you are at least back to your genetic max. You body can only hold so much muscle natually.
It's also hard to get very lean naturally. Let's say you are at your genetic max (best) in terms of muscle and bodyfat and want to cut down. You will likely lose muscle unless you use some mild AAS to prevent muscle loss. You can only get so lean naturally.
If you don't care about gaining muscle you can simply use a light cycle a couple times per year to get leaner than otherwise possible. Yes, you will graudally gain the fat back, bu it's easier to maintain than too much muscle.
Plus, I think it's healthy to stay lean.
