OK.. Eq is a very long acting drug, and takes approx 7 weeks to build to peak levels. 8 weeks is a fine length but you will need to frontload the dose (shoot more the first shot to achieve peak levels faster/immediately preferably).
I would opt for no less than 400mg of Eq and around 400-500mg test..
If you are to avoid the water from any amount of test, you'll need an AI. This is also necessary to avoid gyno and to make sure estrogen doesn't cause health issues from being too high above 'natural'.
The cycle i'd employ may be similar to this:
Wk1-8 Testosterone Cypionate 500mg/wk (250mg 2x/wk) [Frontload with 730mg on day 1]
Wk1-8 Boldenone Undeclynate 400mg/wk (200mg 2x/wk) [Frontload with 665mg on day 1]
Wk1-8 Arimidex 0.5mg ED
Wk10-14 Tamoxifen 40/40/20/20 (dosed daily)
This will be a very effective cycle, with good gains, and with the concurrent use of the AI (Arimidex) you will have little water retention. The Eq will really highlight your musculature in your low fat physique, and a good 10lbs of decent quality muscle could be possible from this cycle.
