Wait a year. At 6'3" you need to be at least 215lbs naturally before considering a cycle, and that's assuming very low body fat (like 10%). You are too young. On the edge, but still too young. You need to learn how to build muscle naturally or you will never do so on steroids and never keep the gains you make.

In case you decide to simply ignore this advice I will comment that your PCT is way too light and not timed correctly.
