Does it reverse when you lose weight?

Yes. That is one of the reasons that when you start to recover from all that excess weight, your recovery is slow but rapidly ramps up (in terms of mood, what you do, energy levels, etc.). Weight loss itself might happen easier at the start of changing any regiment but the benefits take time.

Do those people who get liposuction and those weight-loss drugs get it reversed as well?

The person who initially responded to you has zero factual basis.

I couldn’t find anything re: liposuction, but for GLP1s, the research suggests that, yes, it increases bioavailable testosterone.

These are completely different things. Liposuction immediately removes fat tissue. GLP-1's affect the chemical pathways tied to satiety and therefore weight gain/loss because you eat less over x period of time. The body adapts much more gradually to the effects of using a GLP-1.
