i've tried those too but get inconsistent measurements from mine.I got some pump bottles at a beaty store that pumps 3 ml at a time. Cheap and easy.
I don't know about anyone else, but this seems like an enormous pain in the ass to me.I mixed up my solution and I store it in the fridge. I also just have 3ml syringes from the hospital I work at. Total cost for me was about $3
I can't shake the solution really well as the containers leak but all the solids seem to be mixed and i just use a spoon to stir before i get my dose.
Thanks again all for the input
