Please Help with Possible Cycle ...

Now that im pushing 30, Ive been kicking around the idea of running a different kind of cycle. What Id like to do is run a very low strength cycle (im thinking 300mg Test-c per week) for a longer period of time (14-16 weeks).

The reason for this is because I dont want to put on a bunch of weight, Id rather run a lean cycle and put on a small amount of quality mass while taking off some fat. Can Test C be used for a lean cycle like this as long as Im running with an AI?

Advise is always appreciated!
