Note: There are numerous other
compounds worldwide which contain the substance levothyroxine sodium.
Due to limited space, however, they are not part of this list.
L-Thyroxine is a synthetically manufactured thyroid hormone. Its effect
is similar to that of natural L-thyroxin (L-T4) in the thyroid gland.
L-thyroxin is one of two hormones which is produced in the thyroid. The
other one is L-triiodthyronine (L-T3, see Cytomel). L-thyroxin is
clearly the weaker of the two hormones. For this rea-son it is often
used for a longer time period than L-T3. Bodybuilders use L-Thyroxine to
accelerate the metabolizing of carbohydrates, proteins, and fat. The
body burns more calories than usual so that a lower fat content can be
achieved or the athlete burns fat although he takes in more calories. In
the past L-Thyroxine was often used by competing bodybuilders.
Unfortunately, with increased dosages (more than 400 to 600 mcg/day)
usually not only more fat but more carbohydrates and proteins are burned
as well. The athlete no doubt becomes harder but he can also lose muscle
mass if steroids are not administered simultaneously. L-Thyroxine is
rarely used to-day since most athletes use Cytomel or Triacana. When
used properly there are few side effects to L-Thyroxine. Dosages that
are too high and, in particular, dosages that are increased too quickly
and too early at the beginning of intake can cause trembling of the
fingers,
excessive perspiration, diarrhea, insomnia, nausea, increased heartbeat,
inner unrest, and weight loss.
The dosages taken by athletes are usually in the range of 200-400
mcg/day. We advise that you begin with a small dose and increase it
slowly and evenly over several days. L-Thyroxine is a prescription drug
and available only in pharmacies. One hundred tablets of 150 mcg each of
the compound Levothroid cost about $50 on the black market. Unlike
Cytomel and Triacana, L-Thyroxine is rarely found on the black market.
