The effects of Cytomel are generally the same regardless of the purpose of use, to treat hypothyroidism or enhance fat loss in a performance setting. In both instances, the hormone functions the same as a direct replica of the T3 hormone. Regardless of the initial reason for use, both individuals should be able to enjoy fat loss. The hypothyroidism patient should now have a more properly functioning metabolism, which will help them lose fat. Often this is welcomed as the individual probably put on a fair amount of fat due to the thyroid disorder. For the performance minded, again fat loss is merely accelerated.
