I ended up doing the dbol mid cycle due to a shipping problem and then decided to try a taper at the end of the dbol cycle by cutting down on one 5mg tab a day till I was at zero. Worked fantastic.
The anavar post cycle is to preserve the muscle gains by not having a drastic drop off of test and such from the system. And since it is a mild, but highly effective steroid if you did this for 4 weeks post cycle you can preserve more muscle over just stopping cold. You can time it as well to coincide with the last bit of test/deca/eq in your system after last injection.
I am by no means an expert on this subject, but these are things that I have tried with success. I will examine a group of items and then decide on what may or may not work with each other and at the end of a cycle and then try it. If it works great, if it doesn't no harm to me and I report on it.
I also believe using anavar has been suggested in the past on this board. I just don't have time to do a search.
