Tesa, GH, iu, mg, z-score

[Bastogne22]

Can somebody explain this to me like I'm in the 5th grade?

Why do we start using iu when discussing these? Doesn't it still matter the strength of your vial? Why not still speak in the terms of 1mg/2mg/3mg/4mg? Is it true that in your late 40's/50's you need not be so concerned about your IGF-1 level and that your z-score is just a comparison to other people in your age bracket?

I am currently on TRT and Reta. Looking to add Tesa to the mix but trying to do my research and have a solid understanding before I just start pinning.

IU is for HGH, everything else in this space is in mg.

Standard Tesa dose is 2mg daily.

I thought I had read in some places, maybe not this forum per se, that they refer to secretagogues like Tesa in iu as well.
