Personally, I would take the M5aa powder and put it in a oral solution, and use the dermal for the 1-test and maybe add some 4ad.
12 grams will be too much for the 100ml, unless you know a secret on how to get it to disolve. If you do, please share it with us all. All you need to do is mix all your liquid ingrediants into the bottle you will be using for your applications, be it glass or plastic. Add your powder a few grams at a time, shaking each time. Heat some water on the stove top below boiling, turn off flame, and place the bottle in the water for about 10 minutes, then shake. You may need to repeat this a couple of times before the powder mixes. Remember to shake the bottle prior to applications.
