Ran the liquid clen a few months back in prep for competition. Ran it two weeks on and then two weeks off in the presence of an ECA stack (Bronkaid, Caffeine pills, Aspirin). I can say it seems a tad underdosed as I got all the way up to 120mcgs before I got the dizzy shakes and racing heartbeat. Effective, but I fried my receptors four weeks out and can honestly say that I won't touch clen again because of what it does to my heart rhythm. I would do a gram of test per week long before another 100mcg per day of clen again. Effective, but not for me. I will stick to good old calorie restriction, LISS, and test prop when cutting from here on out.
