i dont remember the dosing that i used but it was a whole bottle one shot and done with. from what doc t said about it and this was years and years after i used it personally is that it should only be used under the strict supervision of a doc familiar with it's use. idk it at the time but it can literally castrate you and is has been used for that purpose. their is no cycling it though it is a one shot deal and it cranks up your natural production back to normal but in my experience as well as from what i have read it doesnt always work and it didnt not work for me. i was back below normal in just over 3 months give or take. again from what doc t said in his video it can bring some people back to normal levels but it is pretty rare and the risk of messing oneself up is pretty high. again i did it a very very long time ago and didnt know any better. you could try it yourself and the chances of finding a doc in the us that uses it and is familiar with it is most likely pretty small. you can probably find doc t's videos on youtube and dig that one up. he is the greek bodybuilder doc george tuertolos(sp).
