lethargy near end of cycle?

is this ever common? i am prone to seasonal allergy induced sickness and fatigue, which could be explaining this, but im not sure.

the cycle is test prop 100mg ed for 8 weeks. im 6 1/2 in with proviron weeks 4-8.

at the gym im still dominating, but my stamina to carry out my responsibilities for the day is fading. the last few days ive been taking small 10-20minute naps later in the day (even when not at home, in my car). also i must note that i havent done cardio on cycle.

could it be stress from putting on so much weight so fast? i went from 251 to 272 in about 6 and 1/2 weeks. Thats got to be hard on the body.

to start i was 6'1'' and 251lbs at say 20%bf, now im at at least 22%bf or more. im not quite sure how much of the 21lbs is lean mass, fat, or water. i do know that i have put on a good amount of chub at my waist line

if my cholesterol was getting out of control, could that cause it?

i should probably go to the doctors and get some blood work done.

Its the increase in weight,
Also get some bloodwork done to make sure everything is ok
