Rush,
I guaranty your gains have subsided because of 2 things.
1)Your body has reached a set point and you have to up your calories to meet the new anabolism that is occurring .Feed the faster metabolism,you have to stay with it.It is a never ending process
2)you body has adapted to the physical stress and you have to up your intensity.
Remember ,in the first few weeks into a cycle,longer ,depending on the esters you are using,The first signs of weight gain are from glycogen retention and fluid retention.When they quick gains subside, and they will, do not be fooled
into thinking that your cycle in now ineffective.
Deca and EQ are just starting to work after a month into a cycle if you haven't uploaded.
