Quick question here, i was just put on TRT for low T, how low does one’s IGF-1 need to be before a dr. prescribes HGH for them. Can anyone fill me in, it would greatly be appreciated.
You are trying to understand how a legitimate provider would diagnose adult growth hormone deficiency? IGF-1 is not primary diagnostic marker:
They’ll prolly do a stim test to see how your GH and IGF-1 responds. Maybe a couple of them
How much variability is there in IGF-1 response to GH? My IGF-1 is always at the very bottom of the range, but I am not sure if I actually have low GH production. For example, could two individuals with the same GH production have vastly different IGF-1 levels?
I’d check out the paper above and refs below:
Percentiles vs age:
So that considerable overlap thing makes me think a lot of variation does occur. I am at 2.5 percentile for my age. Pretty terrible! Maybe I should get some GH tests done. Insurance probably would not cover it anyways though.
I could also do a test with GH, and see how much that impacts my IGF-1 levels. That would let me know at least a bit how correlated they are for me.
I do appreciate the responses guys, I’m going to get some of my levels checked. I’m seeing some minor swelling on my ankles. Not sure what is causing it. Will make an apt to get myself checked out however.
Take care & wish me luck
