I got into this with another member not to long ago about the importance of using test as a base for all cycles. I truly believe this and he didn't. A few weeks later he wound up dead. No, I'm just kidding but I am a big advocate of test as a base. I don't think tren should be ran alone but I believe Standard Donkey has run this a few times. He would definetly be the one to talk to about stand alone tren cycles.
