I just went to take my first dose, so the bottle says for research only, not for human consumption etc.. and it says 50 ml 20mg/ML so i'm guessing 1ml-20gs..the dropper starts at .1 ends with 1ML..put a full ML in some fruit juice..omg **** is like drinking cigarettes..horrible after taste..is this normal? hope i dont have a defective poisonous batch or some **** lol
