IGF-1 on TRT
What the number means, why it moves on a protocol, and how it sits with related markers.
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 moves with blood sugar effects.
The range
How to read the lab range
Lab ranges are age-based, roughly 100 to 300 ng/mL for adults. Results are read against your own age band.
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.

Questions people ask
What does high IGF-1 mean on peptides?
That growth hormone is up. Very high IGF-1 for years is linked to worse outcomes, so it is read next to fasting glucose and HbA1c. Worth raising with your doctor if it sits above your age range.
Does testosterone change IGF-1?
A little, upward. Not enough to explain a big rise on its own.
