I've been trying to find this out but haven't had any luck yet. All I wanna know is if Tbol is a test booster. I'm gonna start taking Tbol in about 3wks but before that I'm gonna be on DNP. While I'm on DNP I wanna take some Methyl 1-D (test booster). I doubt I can run a test booster for 2.5 months. Does anybody know if Tbol is a test booster and if I can run Methyl 1-D for the 19 days I'll be on DNP. Thanks for your help guys.
