T@d@l@f¡l solution/solubility

I was wondering if anyone has experience making a solution from T@dalaf¡l (Ci@lis) powder for volumetric dosing. Thinking of ordering some as it seems far more cost effective than buying p¡ll$ but wasn't sure what solvent I should use/what its solubility is in various solvents. Ideally aiming for 10 or 20 mg/mL.

Update: looked into this a bit and from what I'm seeing t@dalaf¡l's solubility is greatest in PEG400 with solubility of 20.18 mg/mL at 32 Celsius. May not order the stuff to make this for a few more weeks as I still have a few weeks worth of t@dalaf¡l left, but gonna give this a try and will try to remember to update here when I do

Further update: I got t@dàlâfìl to dissolve in PEG400 pretty easily at 10mg/mL with warm water baths and thorough shaking (don't have a mag stirrer yet lol).
