Low IGF - Can tirz cause this?

[cargin]

I just got my bloodwork done and my IGF-1 is 113. For reference I am 21M so the number seemed a little low to me. I've been on Tirz for a month and have been reading that a caloric deficit can lower IGF. Is that possible in this scenario and my GH is probably normal or am I just borderline deficient? I want some reference on whether it's worth starting Tesa/Ipa
