To start I need help with this question: I was making a 309mg solution I realized adding powder to liquid will increase the volume. It is not possible to measure the final amount accurately so I used the weight of the solution to figure out the accurate dosage.
1ml propylene glycol weighs .965g
Powder used weighs .309g
For solution of 5mg/ml I put .309g powder into 62ml propylene glycol
Weight is .309g powder + 59.8g propylene glycol (62x.965) or total weight of 60.109g
So actual volume of solution in mls is 60.109g ÷ .965g = 62.29ml (powder upped volume by .29ml)
So adjusted dosage of my solution is 309mg powder ÷ 62.29m. = 4.96mg/ml
Can someone help verify if my math's correct? If it's correct would it be okay to add less propylene glycol into my solution to get it at 5MG ml?
I hope somebody has tips to help make my solutions more accurate. I’m experiencing slight (strong enough) withdrawal each time I mix a new solution. I decided to use norflurazepam due to a longer half-life. I think it could be a lot more potent than expected when used daily.
I'm now using lab-grade beakers with proper plastic seals. I can’t stir it enough before my wrist starts to hurt, I shake the solution it’s a lot easier. I was using mason jars with a seal that I think might have been absorbing the solution each time making a new one. I thought if I made the same potency of solution each time I won't have to worry about it being absorbed since it's same strength solution so I doubt that's causing my slight withdrawal switching to each new solution.
I think maybe I'm leaving it on a hot plate too long (hours) when I fall asleep without shaking. Possibly it's too hot for too long but most benzos don't degrade in heat for hours I think???
Is Norflurazepam more sensitive to heat is leaving it on a hot plate for hours lowering solution potency?

I get all the powder off the scale tray into the liquid vial. I make sure my scale is on a perfectly leveled surface in a closet corner away from all electronics. I warm up the scale for 1 min + calibrating it before weighing each powder for each new solution using the propylene glycol.
How else do I make a more accurate dose if heat isn't the problem? I don't got money for a more accurate expensive scale as that seems to be the only solution to my problem unless heating for too long is the problem???
