Most safe dose used is 100mgs test every 7days-give or take 25mgs...adex can be used thou..say about .25mgs twice a week...this what i do and feel great---BUT i still can only workout 3-4 times a week or i will overtrian myself...HRT can be great thing just make sure you get blood work and take suppelments for cholestrol and things like that to prevent any future possible outbreaks..
