to me when shut down your shutdown, simple as that, a 19nor will do it quicker but I posted something the other day showing that LH and FSH is shut down in men in about 4 weeks using 250-500mg test cyp, you be supressed for a few weeks first and also supressed if running a mild oral but I neverstood these 2 seperate versions of shutdown, when levels hit 0 they cannot go lower can they?
