Just got some myself bro, havent actually tried it yet but when I do, I will be putting it in with three other A.S's and at a dose of 4 aday for 14 days then taking a 14 day break before doing the same at 5 aday.
I get what you are saying about the muscle growth, personally I wouldnt expect to get muscle gains from just taking clen alone, its a anti catabolic so you certainly will only lose a very small amount of muscle if any when you use it. From what I hear the sides are minimal if you contain your doseage's.
