I think there is a conception that muscle gained from AAS is somehow different than muscle gained by natural means. I've seen many people say this time and time again, and honestly I don't get it... Doesn't make a lick of sense to me. Muscle is muscle is muscle is muscle is muscle...
However there are a few side notes, foot notes, asterisks...
-If you hold water on cycle, you are going to lose the water after the cycle. Water definitely gives you the appearance of being bigger. Not my idea of a good appearance, however... This, in my opinion, accounts for a large amount of the Post Cycle Size loss.
-The faster you get your body back to homeostasis after your cycle the less likely you are to lose LBM. If you allow catabolism to set in at any point, you are going to lose LBM... Regardless if you have done AAS or not.
-If you continue to train hard and eat properly you will maintain your LBM. Let's be for real. The more muscle mass/LBM you have the harder it is to maintain. It's harder to maintain because your body becomes use to being fueled properly and trained hard.
Countless times have I seen people throw proper dieting and training principles out the door when they are in maintenance mode. If you want to maintain you still have to do the following: eat at least at your TDEE, not BMR. If your TDEE stipulates that you need 3500 calories, then you best eat 3500 calories. Keep your preworkout and postworkout nutrition as if you were on cycle. Get a constant flow of protein throughout the day. If you ate 350g of protein per day on cycle, eat 350g+ while you are maintaining. Keep the diet going.
Being healthy, muscular, big... Is a life long choice... You either stick with it or you don't. If you don't kiss it goodbye.
For instance, take me for an example. I took 6-7 years off from the gym completely. Threw my diet and health out the window. From the time I was 16 to 22-23 I kept in the gym consistently. Yeah I started juicing young, 18 years old... Didn't know any better... But I was constantly training hard, constantly eating properly. I trained just as hard off cycle as I did on cycle and I maintained my mass without any issues.
So, like I said I stopped AAS and soon after I stopped working out in order to pursue my music career. 6 years on the road pretty much tore me to shreds. It was not pretty. The state of my body and health was actually quite bad. I was consistently run down, pummeled, sleep deprived, and the list goes on. There's a point to this story.
After the damaged levied to my body from life on the road... Not to mention the stress and all things that come with that lifestyle. I pretty much made a decision to leave that behind and start fresh... Get back in shape. Move my life forward.
Anyways after 6+ years not working out. I definitely lost some LBM and gained some fat. But I didn't shrivel to nothing. I still had size and strength... But as soon as I came back to the gym my body snapped back into the groove for the most part. There were challenges, especially on the fat burning front... Fat has taken longer than anticipated to leave, but I'm down in the neighborhood of 9% body fat. Much of my mass has come back. January 1 of this year is when I got back in to the gym full time. I'm in the best shape of my life now and I am feeling damn great. So over the span of 8 months or so, some natural time and some AAS time... I've made a total body recomp... Size came back much faster than the fat left.
Moral of my little story is even though I lost some lBM and gained some fat in my time away from the gym... I didn't lose anywhere near all the muscle I gained over my original AAS use. And most of it has come back fairly quickly.
Second moral of the story is train hard and eat right regardless of whether or not you are on cycle.
Third moral of the story is music is not a good career
Fourth moral of the story is, don't ever let yourself get out of shape once you are in good shape... Not worth it... It is however worth eating properly year round in order to avoid the frustration of heavy cutting.
