As of now, I have 7 cycles under my belt..by no means does this make me a vet, I always use some form of test in there. In the past, I've used Niles, Redijects, Spectro, QV, and now Omnadren. I can honestly say that i've had a lot better response using a human grade test as opposed to vet. I feel better, i'm not as sore after injections, and i seem to grow better as well. Those are the things that are important to me right now, price is not a concern for me. As Quad stated before in this thread, everyone is different, that's the catch, you don't know what works for you until YOU try it. I've experimented around, and i've found what works for me...no flame taken bro...hope this clears things up...
