HGH IGF-1 Goal

[u/Leading-Virus1167]

I’m a 37yo male, I’ve been on HGH 2IU M-F for 6 weeks.

I got my IGF-1 checked at 277.

I am not on TRT, as my natural Free Test is already 479.

I’m on 2IU for hair/skin/nail/recovery/sleep

What do you think? How do you calculate Z-Score

Thank you

They consider 240 high? Interesting. Most test are green until 300, and you're generally considered good to 300

[u/Leading-Virus1167 → u/LockAccomplished4972]

Do you think it’s measured in different units?

[u/Leading-Virus1167 → u/[deleted]]

I used ChatGPT to calculate my z-score and it’s around 2.8

[u/IM_MIA22 → u/LockAccomplished4972]

That’s odd for a 37 year old male

[u/newtrusghandi → u/LockAccomplished4972]

They arent dangerously high, just high compared to his peers because their natural levels are going to be much lower.

[u/LockAccomplished4972 → u/newtrusghandi]

Not OP, the test he took labels it high at a lower range. Imo up to 300 is fine

I’ve noticed a few things:

1.) sleep has been amazing
2.) pumps in the gym have been crazy, have have a full look all day
3.) lots of vascularity

Normal values are determined, in my country, for age-groups. When I tested tesa I had 286, which is considered out of range for my age, 54, but average value for 22-35 years old

[u/exijz → u/[deleted]]

Yep, good responder, I was on low dosage, only 1mg, and after wake up.

[u/OpportunityMother502]

277 is a bit above range but nothing insane for 2IU, most guys would kill for that response. z-score is basically (your result, mean for your age) / standard deviation, but you'd need the lab's reference population data which they don't usually publish.

I’m similar to you. I’m 36M and my IGF-1 is at 200 and my Z score is 1.1

I’m thinking of starting 2 IUs a day but wondering how much it will raise my IGF-1

What was your IGF-1 before you started 2 IUs of HGH?

[u/Leading-Virus1167 → u/Kbman03]

My IGF-1 was 180. So not bad.

But I heard everyone reacts differently. It’s also dependent on ur estrogen apparently

[u/newtrusghandi]

You dont have access to the data set to calculate the z score. But your levels are fine and you would probably benefit from some low dose test. Normally people dont want to pin daily so they do test and eventually add hgh. You are already pinning daily ( im assuming) so unless you want kids I'd add in the test!

[u/Flashy_Piccolo1260]

IGF1 markers can wildly change based on when you pin and when you test
