what affect does exogenous Testosterone have on natural HGH secretion?

[anabolicmindset]

Does taking exogenous Test will signal the Testis to stop production of natural test, BUT will it affect the natural produciton of GH in the pituitary?

[Mr.X]

from my past reading, increased test levels can increase IGF levels in the body, which is essentially equal to an increase in GH levels

[djsf]

Agree with Mr.X. Some steroids, especially tren, can have a great effect on IGF levels, increasing them a lot. That wouldn'y necessarily mean an increase in GH levels, but you get an increase in the thing that is the main reason for using GH... IGF.

Are you asking because you want to raise IGF levels, or because you are trying to prevent a decrease in GH levels for some other reason?
