Do some more research before you end up with an arrythmia.Originally Posted by zaph123
But to answer your question (and hopefully not give you any stupid ideas before you assess your tolerance), thyroid hormone is stacked with clen during cutting cycles. Thyroid hormone is very catabolic, and clen is anti-catabolic, but both stacked together with a good diet and cardio will cut you up like woah. But they are also very potent alone, let alone when stacked. So do some more research and start with the T4 with LOW doses. Maybe even half a pill. Because believe me when I tell you, there's nothing scarier than a wicked bout of tachychardia (let alone an arrythmia).
