I'm going to be a first time user on Clenbuterol in a couple of weeks. I'm not even close to being cut, but i want to start losing some body fat so i can work my way up from there. I don't wanta stack it w/anything else because i get drug tested alot at work. Can clen be detected in a urine company test? Is OXYFLUX a good brand? Is SPIROPEN brand better? What's the difference? And what would be the best way to cycle Clen. I'm 21 yrs old and 175lbs. Please respond, i'm looking for a good reaction! THANX!!!
