BD is top notch. Never tried any of GTP stuff though. That being said, along with BD, I've had excellent results from QV, LSP, EC Labs. I can't actually say that one is better than the other. All produced good resutls.
You were using test E right? How far into that cycle are you? When did the test kick in for you? I'm half way through week five and I'm still not feeling it, so I'm just curious. Oh yeah, what was your dosage and any other gear used.
