Hi,, i'm on my 5th week of my cycle and every now and then i'll feel really lightheaded and dizzy, it'll last for about a day then go for a few days. Is this normal when taking AS?, its only happened since i've been doing this cycle:
Deca wk 1-10 , 400mg pw
Dbol wk 1-5, 25mg ed
Sust 250 wk 5-12 500mg pw..

Nolva from wk 4 30mg ed

Its not my first cycle, its probably the biggest on i've done..

I'm eating and training good, not to sure why this happens..

Help appreciated..
Thanks.
Mark..
