I agree with Big Andy and the others, cut down the dose and increase the duration of time on. Also, keep the diet in check, this is by far the most important thing to help you reach your goals.
Yes you can take the clen before your a.m cardio. I personally like to split my high dosages into 2 or 3 doses throughout the day. Just try not to take any doses too close to when you go to bed. You will have a hell of a time trying to sleep.
Bro, I have never used their Deca but have used both their winstrol and anavar, which were both top notch. Their products have a good rep, you should be good to go. SG
