As you mentioned this one could be you last cycle, so you may want to do it a bit longer. So I quoted from an article of Big A a cycle that I throughly recomend it. But taking into acount the fact that you are not new into the business you can slighty increase the doses.
You need a testosterone base. 750mg/week is plenty.
You need an anabolic - deca or Eq at 400mg/week is
plenty. You need for optimum growth, a good oral like
d-bol at 30mg/d or A-50 50mg/d.
You use the test and the anabolic non stop. The oral
is 4 weeks on 4 weeks off. Every 6th week (the half
way point between the off oral period - so 2 weeks
after you finish the oral) you have a blood test. If
the blood test is OK, then you can begin your next 4
weeks on oral. There is no reason for you to come off.
The only 2 reasons are health or your receptors are
saturated. If the regular blood test is OK, your
health is OK. If you are still making progress, your
receptors are OK. Coming off, will just sabotage your
gains. That's why I do not believe in set time frames
for cycles. Listen to your body. When you use the
oral, you need to use all the liver aids available - Synthergine,
Milk Thistle, L-methionine, Liv-52, etc.
