Guys. 4yrs ago i did a 8 week course of somatropin (russian). I was getting unreal headaches where i could not lift my head up. nausea the works! Anyway. My eyesight has been getting worse ever since. opticians said all is ok. very foggy sight. i am seeing a british endocrinologist now, since i had an mri scan that showed a pituitary adenoma. it is only 3mm big and on the anterior part of the gland. i had an (ogtt) glucose tolerance test and am waiting for the results! thyroid, test and other hormones seem ok! do you think that the hgh i took back then could have caused this? i am 6'4 tall and age 27.. Any thoughts on this would be great. Thanks!
