My life saver when taking 2 grams of deca .))) Otherwise I get too tired lethargic lazy brain fog confuse words and sex lasts for 1 hours chicks saying I am getting tired and I want to sleep... So viagra is my life saver when on deca. Last summer I buyed some illegal bulk viagras replicas still has viagra in it but these made me so pumpy john holmes style. So my advice only buy orginal viagra. Other wise heart attack coming ...))) Only con about it they are too expensive..
