The war against testosterone is real and ongoing. This place evinces the downstream effects of an increasingly emasculated society. And if "grey" is intended to refer to legal grey area, that is only at the societal level. For individuals, AAS and GLP's are prescribed in various contexts. So they are at times, "legal". Besides, legality is not a judicious metric for the theoretical value of a substance. Jim Crow, segregation, marijuana, cocaine, etc were all "legal" at one time or another.
If we are considering the merits of a substance and attributing value to it, then firstly, supraphysiological amounts of testosterone weren't originally stated. Now, even if we were to account for normal-high amounts leading to eventual excess, condemning men to live emasculated lives with suboptimal testosterone amounts is, in my humble opinion, tyrannical and a nefarious violation. Medically, estrogen to testosterone amount is supposed to be at most around 1:20. With upper range of 54 for estrogen that is over 1000 for testosterone. The average amount in "healthy" men is around 450-500, for "medical" community.
Yet 390-400 is the average today while in the 1950's it was supposedly over 750. At the end of it all, it is easy to say that overdose of testosterone leads to shorter lifespan. A famous king once said before dying, "I would rather live one day as a tiger than a thousand as sheep".
Personally, I don't see 20000 days of living as a disabled, emasculated, person as being superior to living 12000 days as an able-bodied, satisfied, happy man.
P.S:- When it comes to "legal", most people are using GLP's that are not prescribed to them personally. I wouldn't call that legal so any attempted distinction between grey and black in this scenario is moot.
P.P.S:- Considering that hormones literally change the way a person thinks, acts, etc., raising one's testosterone is not just optimal, but mandatory as a man.
