Testosterone with an 8 week anavar kick start is a very effective lean mass bulking cycle. You can keep the gains very clean and with minimal water retention by using an AI (aromasin) with your cycle.
Here's what I recommend:
Weeks 1 - 12
testosterone 500mg/week
aromasin 12.5mg every other day
Weeks 1 - 8
anavar 50mg/day
N2guard 7 capsules/day
After your cycle run the perfect PCT protocol:

You can order everything you need for the cycle and the PCT protocol from ag-guys.com, n2bm.com and sarms1.com.
