Magno Sex Hormones
IGF-1 on TRT
What the number means, why it moves on a protocol, and what people usually do about it.
What it is
IGF-1 is the growth-hormone messenger the liver makes. It is the number people watch on growth hormone or secretagogues, and it tracks recovery and blood sugar effects.
The range
TRT-aware target
150 to 250 ng/mL
How to read the lab range
Lab ranges are age-based, roughly 100 to 300 ng/mL for adults. People on GH aim for the upper part of their age range, not above it.
Why it moves on a protocol
- Growth hormone, MK-677, ipamorelin and CJC raise it.
- Under-eating and poor sleep lower it.
- Liver health sets how much the liver can make.
What people usually do · not a recommendation
- On GH, people titrate to the upper age range and watch fasting glucose and HbA1c alongside.
- Above range with high blood sugar, the dose comes down.
How Magno reads it
Import the PDF or a photo of the report and Magno finds IGF-1 on it, keeps every test on one line, shows the change since the last one, and reads it against TRT-aware thresholds rather than the lab's generic range. The panel it belongs to, Sex Hormones, gets a written verdict with the probable causes and what people usually do.

Questions people ask
What does high IGF-1 mean on peptides?
The dose is doing what it says. Very high IGF-1 for years is linked to worse outcomes, so people keep it in the upper normal range.
Does testosterone change IGF-1?
A little, upward. Not enough to explain a big rise; look at GH or secretagogues for that.
