Ok guys let's get to the bottom of this once and for all...
I'm not a scientist and I'm not going to provide ref's cause I'm not getting graded on this but I'm going to speak from experience.. both personal and my peers' experience..
There may be exceptions as with everything, but IME what I've noticed is that it's pretty much impossible to keep the gains made during a cycle. Now, having said that, let me clarify.....
Let's say you run a 15 weeker and put on ~20 lbs with ~7 of it being muscle (which is a successful cycle IMO) how much of that can one realistically expect to keep once their hormone levels drop back down to normal physiological levels...? Let's say your Test levels were 800 before your cycle, and during cycle went up to 2,500... Your body is operating with supraphysiological levels of testosterone and the anabolic/catabolic ratio is directly related to the hormone content in the body..So is the size and strength of the muscle cells. Why would it make sense for us to believe that the muscle built with a Test level of 2,500 can be sustained at a significantly reduced level of 800..?
Now....I'm not saying ALL gains will be lost, but I'm relatively certain that the majority of gains will deteriorate over time as the anabolic/catabolic ratio goes back to normal and the body no longer has the hormone content to support the extra muscle that you're genetically programmed not to be able to build in the first place..
Please keep in mind I'm only talking about muscle size and strength.. I'm not even talking about the appearance of the muscle, because that's a whole different issue and for sure one cannot maintain anywhere close to the "look" one gets while "on"..
So what's my point...?? What I'm saying is don't start using steroids under the false assumption that you can do a few cycles, build the muscle you want, and walk away with a bodybuilder physique without having to upkeep your hormone levels. It's not realistic and unfortunately it simply doesn't work that way (at least not for me and everyone I know).. If you're going to start using steroids and want to keep the gains long term and keep building on top of gains from the last cycle you have to be prepared to maintain a certain level of Testosterone (at the very least) to allow your body to keep the size and strength you developed during cycle.
In summary, my intention with this post is to evoke thought and better decision making on the part of young guys new to steroids. You have to be aware of the magnitude of your decision to start using AAS and I want you knowing the truth from the get go..Not that you think you can do a few cycles and build the physique you want and then maintain it with protein powder and creatine lol..All the people I know that keep gains between cycles are on TRT. I also know guys that have been yo-yo'ing for years. Up 10 lbs, down 7 lbs.. and granted, they ARE bigger than when they started (so yes you do keep SOME of the gains) but their physiques typically hold more body fat because they're eating to maintain size but their bodies simply cannot partition nutrients the same way and beta fat cells are not activated anymore so the people who ARE able to keep a decent amount of their gains get fat.. Sorry to burst your bubble guys but as I like to say "there's no biological free lunch." What goes up must come down unless you figure out a way to stay up or "cruise."
Lastly, please let me be clear.. I am NOT saying that everyone needs to get on TRT.. What I'm saying is please know the truth BEFORE making the decision to jump on gear and know exactly what you're getting yourself into. I don't want people to believe the same BS that I believed for years as a young buck...
