I came across some Brogen Clenbuterol. I started taking it last week and have not felt the side effects yet. I've taken up to 6 pills so far. Each pill is .02mcg, as is most regular clen. Does anyone know if this brand is shit? I took spiros and they had me shaking on the 3rd day, but these give me nothing. I'm out of spiros and this was all i could get ASAP. Anyone with input please help me out. Thanks
