I don't think it's too much, except for the Deca. I think the test and Dbol are great (although I prefer Anadrol) but when you add Deca, you're asking for problems.
It's my belief, no scientific data to back it up, that at 500mgs of test you're at 95% of your potential gains. Going to 1000mgs will help, but it won't double your gains. I say that so your expectations aren't unrealistic, although the cycle is not over the top by any means. Just have all the AI and stuff you need while on cycle.
