Benzos Ratio question for PG dissolving.

[Mentally_Defective]

Hey guys I have a basic understanding of doing this as I've done it several times already but I am wanting to make sure my math is mathing and that I'm not doing it totally wrong. Any help would be greatly appreciated I have Gidazapam and online it says the daily therapeutic range is in between 50 and 150 mg or like 200 maximum. For better perspective I usually use 50 mL of PG and with the other RCs BZDs it is much easier because I don't have to use as much and simple division let you know how many milligrams are in 1 ml. Would this be the same for godazepam like I would literally be adding a half a gram to it and get it to dissolve or is this assumption totally wrong because once in your body it changes over to the stronger benzodiazepine where it cleaves off the top of the molecule and you are then left with something that has 80 plus hour half life. So I guess my question is is my math math incorrectly and I actually do need to weigh that much and dissolve it or I need much less because it's going to in Vivo in my body anyway? As I mentioned any help would be greatly appreciated. Thanks in advance.
