Well a blast of cyp for 8 Weeks is very modest. I would shoot for 10 to 12 and run the dbol the last 4 Weeks of your blast. If your running 400Mg of cyp from your script then it should be adecent enough amount, but if its ugl I would up the dose by 100Mg and go from there.
Dbol has a very short half life so that will definitely not show up on any blood work 6 to 8 Weeks after discontinuing. your test levels should be back to your doctors range in that amount of time as well.
With the anastrozole im assuming you have never used it before? If not then you have nothing to base anything off of so a dose I would start at is .25 eod and whenever you decide to throw the dbol in there you could bump it up to .5 eod.
you can adjust dose depending on sides, if any, or get bloodwork done for e2.
one more tip, if you want to be 100 percent on the test being back in range for your bloodwork then order the test through someone like privatemdlabs.com right before the Dr visit. If its still not in range reschedule the appointment. But in all reality that should be more than enough time, just a little tip if you ever find yourself short on time.
