I like test enanthate or cypionate at 400mg to 500mg for a first cycle. I generally like 10 -12 weeks minimum for cycles also. If you want to, throw in Dbol at 30mg per day for 4 -5 weeks it will help jumpstart your cycle while you are waiting for the test to kick in. At 205 you want to be eating 300 to 400g of protein per day. This is absolutely crucial, so you are going to have to learn protein content and start keeping count.
This cycle should allow you to figure out how you are going to respond to steroids.
Have nolvadex on hand in case you experience signs of gyno and have your PCT laid out for the end of your cycle and you should keep your gains.
