There are a lot of TRT protocols that non-specialists prescribe which are universally understood to be counterproductive, and one doesn’t need to be a doctor to know that.

The really bad ones are either dosages which are just high enough to shut down one’s natural production but not high enough to replace it, or infrequent dosages (weekly or less) which cause a brief spike of healthy T levels and then a long trough of being too low. Some patients don’t respond well to creams or topical treatments, either.

I think I draw the line at giving someone specific advice regarding how much testosterone they should be injecting themselves with. You shouldn't be doing that unless you have the relevant expertise and know the circumstances and goals of the patient and their medical history. In any other situation it's just irresponsible. However common it may be for random anonymous people in the internet to give out unsolicited medical advice, I can't agree that it's ok. It certainly doesn't contribute anything of value to the discussion.

Can you please quote an amount which was specified - "how much" would imply a dose? What drug? How often?

I suggested a subjective target physiological result with absolutely no specific means to get there beyond "find a doctor."

I gave a subjective assessment of the current state of medicine with the recommendation to find a licensed, competent medical professional.

If I believe someone is being mistreated by his doctor, am I not allowed to suggest finding a new one? What if his current doctor wanted to perform a lobotomy?

"Find a new doctor" is not "medical advice" as much as you would like to conflate.
