I keep on reading that Clen could mess up your heart. Some say its because of increase of BP, which could be monitored and is manageable with drugs. But others say it causes heart muscle atrophy which is much more serious and can't really be helped as far as i know. Any recent info on the topic? Im looking to run it alone during a cut, but not sure how safe it is even at low doses. Most threads seem to site heart atrophy in rodents at really high concentrations (5mg/kg), not sure if any studies were done at low dosages in humans. Any updates would be appreciated!
