The best way to mix powder of this sort is to get a tiny spoon, then weigh out ten flat measures, figure out the average, then use this spoon to dose it out. E.g. a tiny spoon may hold an average of 50mg of m5aa, when scraped flat. So just measure it out into a bunch of piles, then scrape it into a glass and add juice (grapefruit juice makes the steroids more effective/less is destroyed by enzymes). Do the same with 1AD, or whatever. There is no need for PEG unless you are dosing under 2 dozen mg.
