Well that all depends on what you are looking like right now. To be honest March 20th seems a little close to be ready for a show if you are a typical bodybuilding. Personally it takes me 12-16 weeks depending on how much weight I put on in the off season to dial in.

As for the cycle, looks like a pretty good cutter as far as the AAS' you have choosen. I am looking at the cycle in your sig and the thing that I don't like about it is the enanthate. I personally would run the prop the entire cycle. I would also finish the cycle with tren rather then start it.

So to keep it somewhat what you have I would run it like this:

Weeks 1-12 Test prop 100mg/EOD
Weeks 6-12 Tren 75mg/ED or EOD
Weeks 1-10 Eq 400mg/week
L.dex .5mg/ED
PCT

Have you considered running some clen and ECA to spead up fat loss???
