I am confused by something I read about in the steriod profile section. The writer writes "a study, done in the early 80s, a very high dose of Dianabol (100mgs/day for 6 weeks) decreased plasma testosterone to about 40% of its normal value," I read in the forums that most steroids will shut you down in less than a week? Why would plasma testosterone be 40% with dianabol ?? What is producing the testosterone??? Does dianabol shut you down less than other steroids??? Maybe I just do not understand. Thanks
