You say this is your 4th day on DBol ... so are you only 4 days into your cycle yet? In other words, you have only injected the Test once, maybe twice and took some DBol at 40mg/day?
If so, then I would not stress out too much. Not only does it affect different people differently ... it can affect the same person differently on different cycles. I have always used DBol on all my cycles. Usually I start feeling 'godly' and good and LOVE LIVING LIFE by day 5 ... but I have had cycles where I wouldn't feel much until around day 8-10. Same person, same DBol from same source and same lab.
What is your exact cycle lay-out?
