Whenever the topic comes up, most people’s major complaint about Nolvadex is that it lowers IGF-1. Don’t the studies on Clomid also show that Clomid lowers IGF-1? I belive too that the studies showing this were done in women. Does anyone know if studies show Nolva/Clomid lower IGF-1 in men?
Also, on a related note, I know AAS like testosterone raise IGF-1 during cycle. Does anyone know if IGF-1 levels drop during PCT after discontinuing AAS? Is IGF-1 even accomplishing anything muscle related in the absence of testosterone during PCT, that concern about the effect of Nolva/Clomid on IFG-1 is warranted during this phase?
