Information About Testosterone Undecanoate :
1 . Testosterone Undecanoate, also known as undecylenate, is used in androgen replacement therapy primarily for the treatment of male hypogonadism, and is currently under research for use as a male contraceptive.
2 . Testosterone Undecanoate active half-life is 19-21 days,It is injected deeply into the gluteal muscle.
3 . Testosterone undecanoate is gradually released from the depot and is cleaved by serum esterases into testosterone and undecanoic acid. An increase of serum testosterone concentrations above basal values can already be measured the very next day after injection.
4 . Athletes typically find that in doses of less than 240mg per day effects are generally not seen at all. When doses go higher, maybe 320-400mg , new muscle growth is slight to moderate at best, but no incredible bulky gains are ever reported.
Testosterone undecanoate half life:
Andriol’s half life stands between 3- 7 hours.
Andriol’s active life is less than 8 hours.
Andriol peaks the testosterone levels just two hours after taking it.
Testosterone undecanoate dosage:
Andriol as a mild steroid and side effects, dosage at 320-400 mg some even take up to 600 mg per day during the meals
Purpose: the role with testosterone for intramuscular injection of long-acting androgen action for about 70 days. The rapid oral absorption, after 4-5 hours of peak blood concentration, but after most of the intestinal wall and liver first pass metabolism, bioavailability is low; intramuscular injection can avoid first-pass elimination. Clinical applied to men reduced sexual function, aplastic anemia. Primary or secondary testicular dysfunction; middle-aged male hormone deficiency syndromes; aplastic infertility and spermatogenesis disorders caused by anemia.
