what do you mean by cutting G? is it pure GBL? highly doubt it....but if it was you'd be better off measuring out 2ccs with a syringe and putting that in a drink. You wanna dilute in half, take the 32 oz put it in a 64oz bottle and add water to fill to the top. Better do some more reasearch as well as ask your friend what exactly it is that he gave you. U can get seriously taking it the "capful" method.
