agreed, i made 125mg/ml test prop and 185 mg/ml test prop, using EO,,, yeah it holds, but i react sooo bad to it,,, swelled up like a mofo for days, with both mixtures, alot of pain and swelling, not good, waste of money in my books, and waste of 2 weeks of hopeing id get use to it, even doseing benadryl before and after shots,,, does nothing. id try a little bit before u make a whole cycle and waste it if you are allergic, definatly not for me.
