45 yr old male, 207lbs, 5' 10. 4th the cycle. I've used both of these in the past but with no specific ratio of the two. Last cycle was 750 mg sustanon, 200mg NPP a week split in 2 shots, for 14 weeks. Diet not exacly the greatest nor the worst. Not real prone to gyno and take Stane as needed from RUI to ward it off. Looking for a good mass building this go around. The question I have, is there a preference "ratio" to these two or is it just personal preference?
