well, ive had my 4th shot today with the ethyl oleate. ive been using .5ml with 1ml of prop and it cuts the pain by about 80%, imo. its a slight soreness similar to test enanthate and eq. NO FLU SYMPTOMS WHATSOEVER. im so glad. i really believe that the flu-like smptoms are caused because your body thinks the injection spot is infected or has a virus due to the severe pain so your body fights it off with a fever. no injection pain=no infection/virus=no flu symptoms. try it, youll like it
