The 1ml BAC approach for a 10mg vial is the simplest starting point for the math. With 1ml BAC in a 10mg vial, each 0.1ml (10 units on an insulin syringe) = 1mg. So for a typical starting dose of 0.5mg you'd pull 5 units; for 1mg, 10 units. Some people prefer 2ml BAC instead because the lower concentration gives more precision at small doses - especially useful in the 0.5-1mg range where the differences between 4 and 5 units actually matter. The reconstitution itself is straightforward: inject the BAC slowly down the side of the vial rather than directly on the powder, then swirl gently rather than shake. Room temp BAC on cold powder is fine. Let it sit a few minutes before drawing. For a first-timer, the vendor recommendations and forum pinned threads will have the current community-standard protocol - it changes slightly based on what concentrations are available. The experienced users in the vendor threads are the best resource for vendor-specific quirks.
