T4 - 50mcg/tab -20 pills/blister - Euro-Pharmacies

Levothyroxine (T4)

History:  Synthetic T4 has been in existence for almost 90 years, being synthesized in 1927 by British researchers.  It was later used in the treatment of various thyroid disorders, such as hypothyroidism and goiters.  Even today, it remains one of the most frequently prescribed thyroid medications on the market.

Method of Administration:  T4 is administered in oral form.

Drug Class:  Thyroid Hormone.

Primary Use:  One of two thyroid hormones produced by the thyroid gland, T4 serves as a regulator of whole-body metabolism.  Every cell in the body is dependent on these hormones for proper metabolic functioning, making their presence critical for the maintenance of human life.  In addition to enhanced fat loss, which is the main reason most BB’rs supplement with T4, it is also capable of increasing protein synthesis.  In order to reap the benefits of increased protein synthesis (muscle growth), it is essential that the dose remain on the conservative side.  Otherwise, the excessive elevation of one’s metabolic rate will foster an environment more conducive to muscle catabolism than muscle hypertrophy.  T4 also possesses the ability to up-regulate beta 2 receptors, which are the same receptors activated by Clenbuterol and Ephedrine.  This will allow one to cycle Clen/Ephedrine more frequently and/or extend one’s cycle, if needed.  Still, one should not lose sight of the fact that T4’s primary job is to mediate metabolism and therefore, its use should mirror that fact.
