I don't feel like I would be comfortable dosing 2iu/0.02ml accurately, even with a 0.3ml syringe. A 20mg/ml 2mg dose would be 0.2ml, which seems like a much better volume of oil in regards to dosing accuracy, and I can't imagine that being too much oil for most anyone. I guess maybe if you're used to 0.02ml, but that's just a perspective thing. I don't see prop providing consistent enough blood levels for women, and 100mg/ml is, as I said, annoying to dose accurately. I might be wrong here, but that's how I see it
