Maybe because 51-60 year olds run more gear than everyone else![]()
das what im talm boutSince these are taken from people coming in to test, maybe guys trying to turn back the clock in that group running rHGH, unbeknownst to the scientists.
I mean look at the low end, holy shit. Off a cliff. Looks like the age range you feel OLD, and either roll with the decline, or punch it in the throat and fight for every inch.
Thanks for the additional insights. I’m definitely trying to be in the throat punch category!Since these are taken from people coming in to test, maybe guys trying to turn back the clock in that group running rHGH, unbeknownst to the scientists.

Well at least you came with some facts, BUT , As per the RULES, proper forum etiquette is to "introduce yourself in the NEW MEMBER THREAD" Have a Grateful Day.There are different IGF-1 ranges and age ranges broken out at the link below for the Labcorp test. I think this web page is more recent than the document Ghoul posted (copyright 2021, thank you for that) so it might reflect new information or an evolution of testing methodology.

man you really are one of the most helpful guys on this platform. thank you for your high quality/effort posts.The way risk is measured is by IGF-1 level for your age, not the dose of rHGH.
Find your ULN (upper limit of normal) IGF based on assay type(ie lab that performed the test):
View attachment 345268
Your risk of developing signs of acromegaly depends on how much higher than the ULN you are:
View attachment 345269
At 1.3x ULN acromegaly features could begin to develop at between 2-5 years if you sustain IGF this high.
At 1.5x initial features can develop at 2 years.
2x starting at 1 year.
Above 2x acromegaly can begin to develop in less than a year,
First is soft and connective tissue, lips, nose, ears, organs, fully (lips) or partially (cartilage) reversible if you stop in time.
Then bone changes slowly over time, forehead, chin, teeth begin to misalign, irreversible.
It happens so slowly even family members often miss it for 5+ years.
Damn, my upper level is going to drop again in a couple years . . .The way risk is measured is by IGF-1 level for your age, not the dose of rHGH.

Dont feel bad, my natty z score is -0.9. So we’re like negative z score brothers or something.My natty Z score is -1.0. Yes, negative.![]()
What were your starting values?After 7 weeks of 4iu/day my Z Score was 1.8 and IGF-1 was 303. I'm 45yo. I've got follow-up labs on Friday and that will be about 15 weeks so I'm curious what I'll find.

Why you gotta make me admit I didn't get adequate baseline labs?What were your starting values?
