igf-1 and trt

[christophchicago]

I have been on TRT for approx. 4 weeks now, new labs coming up soon, and was curious as to the effect " standard " TRT ( i.e. 100 mg test cyp IM weekly, 250 IU HCG 5th and 6th day sub q , no E2 meds as of now) has on IGF-1 levels. Prior to begining TRT, my labs showed an IGF-1 of 185 ng/dl, I am not sure of the range on this test. I am 40 yrs old btw. Is this low and will TRT cause an increase ( hopefully )? I believe a level between 300 and 450 is considered desirable

I cannot seem to find much material on this matter, and results seem a little vague on what I did find.

Anybody have any empirical data on this ?

FYI, If E2 goes to low your IGF-1 will go down. I stay at about 280-312 both pre and post HRT, except when my E2 was to low. HGH seems to be the only hormone I produce well...which I find odd.

It's not a steroid hormone. That may have something to do with it.

Yes that is a great level..how old are you?

IGF-1 comes from insulin right? So wouldn't that level have more to do with how much your body is producing insulin to deal with blood sugar levels? Can anyone explain how they are related to androgens or estrogens?

I do not have any specific knowledge on this, but can say on my last blood test, my insulin levels were BELOW the range, so they were LOW.

And that's a good thing.
