About TEST UNDECANOATE

Testosterone undecanoate is an esterified form of testosterone which is attached to a long fatty acid chain. The lack of a methylated site on the carbon 17 eliminates the adverse effects on the liver found in other testosterone analogs.

Testosterone Undecanoate is the undecanoate ester form of the androgen testosterone, with gonadotropin-secretory inhibiting and hormone replacement activity. As testosterone inhibits the secretion of gonadotropins from the pituitary gland, administration of testosterone decreases the secretion of luteinizing hormone (LH).

By inhibiting LH secretion, the growth of Leydig cells, which are normally stimulated by LH to produce testosterone, may be suppressed. In addition, this agent promotes the maintenance of male sex characteristics and can be used for testosterone replacement in hypogonadal males.
