Okay Bulkeh, in order for people to advise you, maybe you can clarify a few things
1. There are MANY different test blends among the 1000s of UGLs out there; what are the contents of the Test-400 you're referring to?
2. In your OP, the context made it seem like you were only running a cycle of dbol and test for 4 weeks, but maybe not continuing with the test once you discontinued the dbol and left for vaca; that's why many people have come in here with criticism and assuming the worst of your plans. I see you said you're planning on 6-8 weeks; if your test were short ester only, I'd say that's a good idea. However, since it seems like your test blend includes a ridiculously long ester like undecanoate, you might wanna extend to 10 weeks or longer. Just my personal opinion because it will maximize the different esters you have. If you're just planning on using the blend for the week or two you're out of town then that would be a different story. Just my personal opinion.
3. Just some friendly advice now...maybe don't call everyone big bulbous clouds. Your name is Bulkeh so why are you insulting large people? Lol.
There's always going to be someone bigger than you, more shredded, stronger... exhibit some humility, humbleness, whatever you want to call it. You will experience a more desirable experience here.
Good luck with your cycle!
