Just sharing an experience I had with an oral t3 suspension from a research chem supplier. T3 is a potent hormone which in my experience, absolutely melts bodyfat away. I have used T3 in tablet form and Liquid form and experienced great results. However, my last experience sent me the hospital for 4 days with AFIB. As you know, when you take the liquid form, the hormone is suspended in a liquid. Before each use you must shake it well and draw with your syringe, measuring accordingly. However, as my bottle began to het low, I'm guessing the remaining liquid became much more concentrated resulting in an inadvertent overdosing. Of course after administering high doses over a period of days, an intense fatigue overcame me, along with a feeling of fullness in my neck or throat. In addition, I became short of breath, constantly bringing my palm to my chest. These symptoms of course prompted me to visit the local ER. After a quick EKG, I was admitted due to atrial fibrillation (irregular heartbeat) and tachycardia (rapid heartbeat). Needless to say after a few shots of coumadin, a prescription for an oral blood thinner to mitigate the risk of stroke that accompanies AFIB. My third day my Dr decided to "convert" me back to sinus (normal) rythm. They basically knocked me out and forced an electrode down my throat near the heart in order to zap it with electricity. However, despite being unconscious, my gag reflex and coughing converted me without having to be electrocuted lol. I was discharged the next day and followed up with my cardiologist. Happy to say it was an isolated incident. So.......be careful with any T3. Choose your source wisely, dose properly, and LISTEN TO YOUR BODY! I hope this is some benefit to someone considering taking thyroid meds. Has anyone else had a similar experience? Thanks for reading!
