yes. i had test levels checked some 5 years ago and they were at the low end of the norm for a twentysomething man. i initially took that as fate and forgot about it for 2 years or so. then i came across various bb sites on the net and hooked up with some local sources. since then i am constantly on. i bought some clomid first but sold it only days ago since it was only collecting dust
but i am not shutdown completly, although my nuts are considerably smaller than they were years ago. before i got my vasectomy i let them test my sperm and i had active sperm even after 1 year of continous use of test! thats not uncommon though and the reason why a working male contraceptive has not been invented yet: test only does not work 100% to achieve azoospermia.
i will be on this "super-HRT" forever i guess. gear is dirt cheap here in Europe and i get a routine screening of blood and urine values and a prostate exam every year and its all in the normal range so far. i do lower the dose to 250mg every 10 days in my "off" time now, its enough to support a good amount of muscle and always-on libido.
