For a beginner, and according to your question, it leads me to believe you are fairly new at this, what you are running is plenty. In fact, I would say, too much! I disagree with Pip Burn on this one. 600 mg of test is NOT a beginner's dose...at all!!! Way to much. Where do you go from there? 750 mg? 1 gram per week?
How will you ever know how your body responds if you start right away with ridiculously high dosages? The key is to find your sweet spot...that is...what is the lowest amount that you can take that will produce results?
In addition, you shouldn't be mixing too many compounds at first. Start with one...like test for example at 250-300 mg per week for 12 weeks and then the second time around you can either do the same, if you had good results, or try adding another compound. Remember, these are products that can totally, 100%, mess you up, if you're not careful. I don't mean to be the deliverer of bad news here, not my intention, but safety should always be your number one concern.
