TweetI would reccomend adding deca instead of adding more test. If you got slight acne from 500mg of test, then adding more testosterone will more than likely result in increased sides. 750mg is a pretty high dose for a second cycle IMO, I would advise something like this, as suggested by the posts above mine:

Weeks 1-4: 20-30mg dbol
Weeks 1-12: 500mg Testosterone
Weeks 1-12: 300mg Deca
