Applications & Main Function

Testosterone undecanoate is an esterified form of testosterone raws 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. It is currently getting further developed to be an alternative to testosterone enanthate or testosterone cypionate by Paddock labs, and this new injectable steroids has an FDA status of tentative approval. The original approval by the FDA of a product from testosterone undecanoate was done in 1953.

Testosterone Undecanoate is the undecanoate ester form of the androgen testosterone steroids, with gonadotropin-secretory inhibiting and hormone replacement activity. As testosterone inhibits the secretion of gonadotropins from the pituitary gland, administration of testosterone raws 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 Steroid Powder replacement in hypogonadal males.
