Among the men's health supplement, especially muscle nutrition, most supplements have HGH, IGF-1.


Why IGF-1 is good for NBE?

I read the articles that IGF-1 stimulates muscle power, T level.

also, IGF-1 causes breast cancer.

and some PCOS girls have high level of IGF-1.

Many articles say that IGF-1 is good for men, it is relative in T, 



I'm very confused... please explain about this!! Please!!
