So the process of aromatization is helpful to improve the production of IGF-1 from HGH, but the product of aromatization negatively influences the same conversion? Or have I misunderstood something?Estrogen does lower GH response resulting in reduced serum IGF-I levels, while aromatizable androgen (e.g., Test, Deca, EQ, Dbol) increases GH response resulting in increased serum IGF-I levels.
While the process of in situ aromatization positively regulates IGF-I a la rhGH, the aromatase product (e.g., E2) negatively regulates IGF-I a la rhGH.
Notably, trienes like trenbolone dramatically reduce IGF-I but increase muscle (satellite) cell responsiveness to it. That is, despite low absolute serum IGF-I levels with tren & rhGH, there will be better local tissue utilization of the IGF-I isoforms that GH increases the activity of.
