If you're handling drugs that are active in the milligram range you need a really good scale as eyeballing alprazolam most likely will lead to a black out. You could also dissolve the alprazolam in food grade PG, for example at a concentration of 1 mg/ml or maybe less (depends on the solubility) but you still need a good milligram scale.
Go for about 5 mg/ml according to online charts.
I never said the OP should dose an entire 5 mg. This ratio is used to dose out etizolam or even C-lam. At least that is what I have read repeteadly on BL. It makes it so about 10 drops equals 1 mg.5 mg/ml of alprazolam would be wayyyy too strong... that's a concentration you'd use for a diazepam solution (which is 1/20th the potency of alpraz).
Pharma alprazolam solutions are dosed at 1 mg per mL or less.
