In the 90s I was part of a study, all subjects was taking aas and hgh, the subjects taking the nolvadex head very low IGF levels, the once not taking nolvadex head high IGF, I was not taking nolvadex and I head high level of IGF. The study was never repeated, I think a more controled study is needed on this nolvadex subject. The subjects with the low IGF, after they stopt the nolvadex the IGF level it did go up.
I am not sugesting to anybody to take or not to take novaldex , I am just shering with you a true story.
