i think 1mg ed for starters, it also needs to be shot at different locations to get the oil spread out evenly(5 or so injections ED, ouch!). it is also important to get the oil in deep so it gets under the muscle and pushes it up. you also must massage the muscles all day long(to prevent bumps from forming) and should inject pre work out to get blood in the muscles . i have never tried this and never will. i dont recommend, unless you are very educated.
