Yeah, that's not too bad for your height and weight (from your other thread). You shouldn't need to bump it any higher as long as your diet and training are in check. Remember, clenbuterol is just the icing on the cake. Using ketotifen will allow you to run it the cycle longer but in my opinion I wouldn't go past a couple of months. Everyone will have a differing opinion but if you need to use it longer than 6-8 weeks then your diet is off or your hormones and/or thyroid are way out of whack.
