> Chemistry trumps psychology

To nitpick: The mind is applied biochemistry. Psychology intervenes in the chemistry, like many other activities do. The goal of that is to solve the root cause so that your future levels will be maintained at the right level, instead of just forcing the level by sourcing the respective chemicals externally.

A good rule of thumb in biology and particular any kind of hormone production and balance is "use it or lose it" - if you start regularly receiving something externally, internal production will scale back and atrophy in response, in many cases permanently.

Psychology can change neurochemistry but only in certain limited ways. Many people are on antidepressants long term because that's the only thing that works for them. Taking antidepressants is already stigmatized enough. People should just do what makes them feel best over the long run. Your rule of thumb does not trump hard-won personal experiences.

We don't really know how SSRIs work, but there's some evidence that it's through desensitizing serotonin receptors, not directly addressing the lack of serotonin. If so, "use it or lose it" doesn't apply; long-term adaptation is the point, and SOMETIMES does persist after quitting.

There are ways to "hack it".

For example, ~6 months ago I started trt (testosterone replacement). It was the best decision health wise ever. I feel way better psychologically, first time in my life I managed to stick with cardio training for so long (before 3 months was the most). There are other benefits too.

So what about the "loose it" part? Well there is a hormone called HCG one can take a twice a week to trick one's balls into producing some natural testosterone. Its use prevents atrophy and infertility.

It is unknown however whether this production is a contributing cause or an effect of carcinogenesis.

    Interesting.

    Well, I don't think you'll be able to avoid testicle atrophy even if it minimizes it, but the important part is understanding the tradeoff. Particularly, that adding testosterone will cause changes throughout your entire body (including, for example, shortening life expectancy a bit), and that adding other hormones to the mix will likewise cause changes around the entire body and not just one single process or organ.

    But it's your body, your life, your priorities and decision. I also wouldn't consider it a good decision health-wise to take steroids to get huge, but I have no problem with someone deciding that absurd bulk is their main goal in life and worth the tradeoff.

Very basic and very often wrong rule, so take it with a grain of salt.

Insulin for example is the opposite. "lose it then use it" would be a general rule for type 2 diabetics where insulin resistance commonly due to weight gain is the primary problem. Losing the weight leads to better uptake and usage. For a type 1 "lose it then use it" you typically lose the ability to produce insulin to an an autoimmune disorder, then are stuck using insulin for the rest of your life.

The body itself typically attempts to main homeostasis, but at population scales this is something that is going to have a massive range of ways it shows up. Evolution, at grand scales, doesn't care if you survive as long as enough of your population survives and breeds. At the end of the day you might just be one of those people that was born broken and to work properly you need replacement parts/chemicals. A working medical system should be there to figure out which case is which.

    > Insulin for example is the opposite.

    You're describing entirely orthogonal issues. In case of insulin resistance, your natural production is running full blast with demand exceeding supply because the consumer stopped caring about the hormone. In case of autoimmune disease, the natural production was killed - you can neither use nor lose what is already dead, and even if some capacity was left it will either soon be killed or atrophy under external insulin, but it will not be mourned.

    So no I would say it is exactly the same - "use it or lose it" - but that does not mean that there is never a reason to manually overrule your body's attempt at homeostasis through direct manipulation. It just means that there is a very significant consequence to the process.

    As a somewhat sidenote, this is also why I dislike the idea of trying to classify people into "normal" and "divergent/atypical". In my eyes we're all normal people and an entirely normal aspect of being a human is that we all differ and have individually specific needs by virtue of being built by a trillion micro-meter sized workers, each with their own hand-copied version of the blueprint, only caring about the millimeter of you in their immediate vincinity and not really talking to any of the others.
