You are delusional and no; you are not listening. Your logic is a fallacy. It's based on lacking information. And even if we disregard all the physiological consequences, of which knowledge you are lacking, you are not listening; your are high on drugs. If you can't see/feel that, then you are not as enlightened as you made yourself to be in the ketamine discussion.
Bodybuilding is a slow process. It's not going to end after a next blast. There is still going to be that and this that you'll want to achieve and this never really ends. So you need to make it sustainable. Now you are just weak, you don't want the feeling of being on to go away. It's a scary process, I know, but you sound like a self absorbed drug addict. Rationalizing to him self why he should continue using the drugs. As I said, and you didn't listen, your mind is on drugs, you need to get to physiological levels in order to feel, think, reason, etc. as a SOBER person.
You know, do what you want. But for everybody else reading this; no, being constantly on cycle is not healthy, and here you can witness a classical drug addict behaviour. Not every drug addict is on the street putting needles in his arms. There are various levels of addiction, one of them being functional addict. Aas have a broad effect on your mental state, for some it's more pronounced and for others it's less, but they effect us all profoundly. Namely impulsivity and an unstable personality disorder, which you can see here for yourself.
No matter how you put it, aas are trash drugs, and you can not make them safe or healthy. Cycling all the time, just leads to all sorts of neurobiological chit. So don't cycle all the time. Simple. But if you do, then at least be cognisant of your changed behaviour and personality.
