Is Test a must for every cycle?

[steropower]

You need a maintenance level of test in your system, as these other compounds WILL shut you down. That is why Everyone around here preaches TEST with every cycle. You won't die without it, but as Shifty said, you are male, and unless you want to be a hormonal chick while on cycle, you should use test. at least 250mg/week IMO.

How can Test keep you up since by its own can shut you down?

I need to read something about this.Any source?
