That's the right way of doing. A testosterone solo cycle is the best choice for a first go. Your body will be hyper-responsive to gear, so you will get great results just with testosterone. It is nice to see that you are planning to use an AI, but arimidex is not the best choice. It would be much better to go with aromasin. It has so many advantages over arimidex, that it would be a shame not to use it. First of all, it is a suicide aromatase inhibitor, so there will be no estrogen rebounds with it, which is not the case with arimidex. Secondly, aromasin will increase the levels of good cholesterol, and will decrease the levels of bad cholesterol. The situation is completely opposite with arimidex. Additionally, aromasin will increase IGF-1 production by up to 25%, which is not the case with arimidex. Just make sure to be using good quality aromasin. Personally, I get mine from roid mass, and it is very good. 10 mgs EOD is a good dosage, and you should be using it from the first day of the cycle.
