A "caloric deficit" not a good idea but neither is excessive caloric intake.
It's important to note some of the physiologic differences that occur AFTER PCT.
Of course the major difference is
a reduction in SKM anabolism yet just as important is the diminished desire to hit the gym.
The net effect is a decreased metabolic rate and a reduced need for calories, and is the reason diet and exercise are just as important, if not more important AFTER cycling AAS!
It's for these reasons many folk tend to increase TBF and lower LBM, in that interval that follows successful PCT .
At best AAS only set the wheels in motion the remainder requires a lifestyle change OTHERWISE
gains will be lost!
