IGF-BP3 blood test

[nothuman]

Is anyone familiar with this blood test? My last doctor ordered it for me in addition to IGF1. I've googled a bit but I'm wondering if anyone here knows how useful it is.

One ifbb pro from europe told me he get this test cause its the part of the igf-1 that “ counts” and “ gets used “

Classic meathead as you see from his response but his trainer told him to do it

This is very big guy , 115 kg shredded at 1,74 m

Sory for not being much help NH
