Ok, so I'm starting my second cycle of FinaFlex Hardcore (550-XD was my first) soon, and it is a testosterone amplifier... my question is: can this be run with Deca? Because I know Deca should be run with Test, so would it be possible?
Also, if anyone knows, would it be safe to stack FinaFlex with something else? I heard of someone stacking DMZ with it, but I don't know if that is safe...
