IGF-1 Production and testosterone

[frxfrxfrx]

Does anyone know if using testosterone alone (with AI) has any impact on the endogenous production of GH, which leads to higher levels of IGF1 if the testosterone dose is relatively high?

Test and e2 both cause higher secretion of igf1

but test does it by increasing gh and e2 boosting gh to igf1 conversion right?

Just rechecked and actually test boosts GH production of igf1 and e2 actually reduces it by overproducing IGFBPs
