Hey bro, it's very cheap and easy to test the PH of anything-all you need to spend is about $6 at a swimming pool store. Buy the PH testing strips in the small round container-then take a strip, dip it in the 1-4b or whatever you have and read the color chart on the bottle- the PH should be between 7.2-7.8. If it's too high, add white vinager in small amounts until the PH is right. Straight 1-4b is hard on your body and is a bith to come off of- make real G and you're better off- if you need the recipe, e-mail me.
