The effect of resistance training on serum insulin-like growth factor 1(IGF-1): A systematic review and meta-analysis - PubMed
We have successfully demonstrated that resistance training was associated with an increased IGF-1 level among those who received the training for ≤16 weeks, among participants older than 60 years old, and among women. Further studies are warranted to clarify the mechanisms underlying the...

"Subsequent analysis of the relationship between participants' age with plasma IGF-1 alterations revealed a U shape correlation in non-liner dose response, in which resistance training resulted in a declined IGF-1 level up to 40 years of age."
"However, significantly lower insulin-like growth factor 1 was observed in subjects younger than 60 years (OR, −4.80; 95% CI, −7.74 to −1.86, p=.001)"
Muscle hypertrophy training does not suppress the GH/IGF axis in young adult males - PubMed
The resistance training protocol prescribed for muscle hypertrophy did not suppress the GH-IGF-I axis, but it did cause alterations in IGF-1r gene expression and in IGF-I kinetics compatible with increased IGF bioactivity.

but an increase in igf1 / gh??
it lowered testosterone, and the igf1bp3 levels stayed the same.
does hypertrophy seriously stunt growh?
