Just to expand, it is always wise to use a test base (like Andro the Giant) when running an anabolic cycle.
When you take a PH like Super Mandro your natural testosterone production will decrease which can lead to you feeling lethargic - the last thing you want while on cycle is to be in a prime muscle building state but to tired to do anything about it.
Andrio the Giant in my opinion is the strongest test base on the market as it actually converts to testosterone.
