Labs versus reality of windows of normalcy - where’s the truth lie?

So basically you hear about how finasteride alters 3700 genes somewhat permanently, many of us have indicators that are low like pregenalone or andorsterone (my case). And I look it up and it’s like “yeah without proper andorsterone, which results from inproper 3 a signaling, your fucked”.

But then I have these random windows of 100% recovery and I see cases where people improve. What’s the truth? The body can’t possibly be producing the windows and improving if the reality in the labs is as bad as it is right? But some also say there’s merit in them. On one hand my labs and my andorsterone levels terrify me bc it feels irreparable but then I have windows where I feel fine followed by devestating crashes.
