I know a lot of guys are going to like the 100/200 blends better because they like to run test lower. But for me, I'd rather have the 200/200 blend. Just got done running Test at 500 per week and Tren at 400 per week and everything went great. I love the higher test in my cycles. I feel better, my libido is better, and I don't get the sides that a lot of people do
