How old are you? I wouldn’t check my physical height/measure it unless you’re at an age where you normally still can get taller, because I don’t think that’s how it works (unfortunately)
So what i’ve noticed, is that when I was on my first semen retention streak (way before i knew about sapien) at like week 4, people kept asking me how i’d grown taller, that i look tall etc (mind you I was 28 then, no way I could of grown).
I also felt taller, this was due to how i perceived myself - the moment I measured myself, i reminded my subconscious that I’m not actually taller at all - and suddenly no one commented on that again/told me i looked taller etc.
It’s the same as looking in the mirror every day to see if your face got more handsome, or nose got more lean or whatever other physical attribute youre trying to change - I’m certain it will have a much better effect by not actually looking in the mirror, and letting your subconscious take a looong time to overwrite the old belief of who you are and what you look like.
