Just so you know........
T3 will potentiate the effects of both clen and ECA, particularly on the heart. Thyroid in general upregulates beta-receptors. While this may help with fat loss, it will also sensitize cardiac tissue to beta-receptor stimulation and cause palpitations, tachycardia and/or potentially serious arrhythmias if you are susceptible to them.
I knew a male bodybuilder a few years ago that was doing this and had problems. I had to explain the interactions to him.
The T3 effect on beta-receptors may take a little time, so the enhanced effect may be delayed, just when you don’t expect it. In contrast to T3, clen down regulates beta-receptors.
So, if shit happens during a heavy leg routine, you know why. Be careful and use common sense. Remember, clen has a 36-hour half-life. Might want to have some beta blockers (propranolol) around the house just in case.
