L-Thyroxin (Levothyroxine) by Berlin-Chemie: results, dosages and side effects

L-Thyroxin is an oral drug manufactured by Berlin-Chemie and containing Levothyroxine etotifen hydrogen fumarate, which is a type of medicine called as antihistamine. In medicine Levothyroxine relieves and prevents eye itchiness and irritation associated with most seasonal allergies. It prevents the release of histamine from mast cells and also blocks H1 receptors, so that any histamine that is released is prevented from having an effect. In bodybuilding L-Thyroxin is very popular by its ability to inhibit the down regulation of beta receptors caused by drugs like Clenbuterol and other similar acting products. L-Thyroxin has the role to prolong their effects. L-Thyroxin come in boxes, each unit containing 30 pills (1 mg/pill).

L-Thyroxin acts on the body's beta-adrenergenic receptors, primarily the beta-2 receptors. As a result of this process the use of L-Thyroxin with compounds such as Clenbuterol can prolong the cycle and become effective for a more extended period. For example Clenbuterol alone can be used in a two week cycle, while if L-Thyroxin added, it allows athletes and bodybuilders to use Clenbuterol for cycles of ten weeks or sometimes even longer. Also due to the fact that L-Thyroxin cleans the beta-2-androgenic receptors it is thought to increases the effects of some steroids. A normal dosage for L-Thyroxin (Levothyroxine) is usually 2-3 mg per day (two to three 1 mg tablets) to prevent the usual down regulation that is often seen with the use of clenbuterol or other typical compounds.

Some side-effects may occur with the use of L-Thyroxin due to the drugs antihistamine properties. These include appetite stimulation, weight gain, and drowsiness. Other common side effects include appetite stimulation, weight gain, dry mouth, dizziness, headache, joint pain, muscle aches and pains, nausea, runny nose, shivering, sore throat, sweating, trouble sleeping, unusual tiredness or weakness and vomiting. These side effects are all commonly associated with strong antihistamine compounds. In some rare cases bladder inflammations may occur.
