Yeah, but if I am feeling good, still have a sex drive and am not losing muscle then.....Why would I care what my test levels are? My natural level is already half what it is supposed to be.... Yet I still wake up with a boner in the AM and have made 2 children in the past 5 years.
But yeah, my levels could be suppressed even with all the positive signs.
Because your testosterone levels are not really directly responsible for your sex drive, estrogen and dht play a bigger role, why would you care if your testosterone is low, because that's the fast route to developing prostate problems, when your testosterone is low you loose muscle easier and gain bodyfat faster, having your hormones out of whack plays a role in your mental health.
All of these things might feel fine today or tomorrow but sooner or later they will not.
I'm absolutely not trying to lecture you or tell you what to do because you're a grown ass man with kids and you can do whatever you want. All I'm saying is that your personal experience does not directly tell someone else what will happen and you might not care about the long term repercussions but someone else taking your advice might not want those things and not know that they exist.
That's why the way we "feel" dosent often tell us the whole story. Someone could be on the verge of a heart attack and feel 100% fine and never know it until the heart attack happens and it's actually quite common, just like people can walk around with low testosterone and all these things that don't show their face right now but 10 years down the road you may directly pay the price for it.
Again, I'm not telling you what to do I'm just trying to explain the bigger picture here
