.......As for the dosage, one should be very careful since Cytomel is a very strong and highly effective thyroid hormone. It is extremely impor-tant that one begins with a low dosage, increasing it slowly and evenly over the course of several days. Most athletes begin by tak-ing one 25-mcg tablet per day and increasing this dosage every three to four days by one additional tablet. A dose higher than 100-mcg/ day is not necessary and not advisable. It is not recommended that the daily dose be taken all at once but broken down into three smaller individual doses so that they become more effective. It is also impor-tant that Cytomel not be taken for more than six weeks.
