Do not inject that shit!!! Take it orally, as already said 50mgs (or 2cc's) is about max... Ref-B it has been rumored for some time is underdosed. Whether that is true or not, who knows I have never seen a definitive test. Word had it though that each 25mg /cc probably contained something closer to 20mgs / cc. Start low and if you do not notice the effects you are expecting move the dosage up...
