Cytomel Profile Excerpt
If you aren’t taking anabolic steroids with your Cytomel, however, your body may start to eat away muscle to provide energy for you to function. Remember mitochondria/ATP aren’t very picky, but they are very efficient. What I mean by this is that they will use whatever is on hand to generate energy for your body to continue functioning…fat, protein, glucose….it doesn’t matter to ATP, as long as there’s something to give them energy. Taking this drug will increase their need to find something to burn to create this energy. Ergo, if we aren’t taking anabolic steroids while taking our T3, we may lose too much muscle, especially while dieting.
