im tired?

Im on my third week of my sustanon/ deca stack. I feel more tired than normal. I get at the very least 8 hours of sleep but usually 9 or 10. I know my stuff is real cause i have already gianed about 10lbs. I was wondering if this is normal or not and what i could do to change it. I also eat plenty and take vitamins.

thats normal bro...i ran a sust/deca stack for my 1st and i slept 9-10 hours at night, then i would slip off and take 2 or 3 naps at work...i was tired all of the time...your body is trying to repair and grow

thanks, that was what i was hoping
