On legalgear.com the have a transdermal that has 10 grams 1-test and 6 grams 4-ad in a 240ml bottle its called LGP 1-T. Thats the most PH I've seen in one bottle thats why I wanted to ask about it. How did they put that much PH in a bottle and is it affective? If not then how much should I put in my homebrew to get the most out of it.
