Questions about TRT effects on IGF-1 and HGH

PAUL-E · Apr 2, 2016

I Know testosterone replacement therapy can raise IGF-1 levels but does it also raise Growth hormone?
I know GH turns into igf-1, so how then does testosterone raise igf-1?
Testosterone administration increases insulin-like growth factor-I levels in normal men - PubMed
I have no pre TRT igf-1 level tests and would encourage anyone to get a baseline before starting TRT.
For those who have pre TRT igf-1 and post TRT igf-1 levels can you please post them? I would be interested to see the difference.
I have also read of people being GH deficient when given the stimulation test but had "normal" igf-1 levels any one have any info on this?
Finally is there any way to accurately test growth hormone without coming off TRT and rechecking igf-1 levels?
.
A interesting side note from the link: Treatment with Nandrolone did not change serum levels of IGF-I but did decrease the level of the major serum IGF-BP and therefore the level of bioavailable IGF-I may be increased in the ND group.
Thanks

I just had blood drawn two days ago, and I'll post up when I get the results. Fortunately, I have pre-TRT IGF-1 levels documented, and am interested to see how much (if any) they have increased since I've been on Sermorelin for about 3 months.

It's kind of early in the game to see any significant results with the Sermorelin, but I'm definitely curious to see if there has been any change at all yet.
