Testosterone Undecanoate Oil CAS:5949-44-0

Description

The history of testosterone undecanoate is a long and complex one. The drug was first developed in the 1930s as a testosterone replacement therapy, but mass gain steroids course for adults it wasn't until the 1960s that it began to be used more widely in medical settings. Today, testosterone undecanoate is still commonly prescribed to men suffering from low levels of testosterone, but it's also being studied as a potential treatment for other conditions such as obesity and cancer.

It is currently the most common form of testosterone used in medicine and has been shown to be effective at treating many conditions related to male reproduction, such as low libido, erectile dysfunction, and low sperm count. Testosterone undecanoate is also sometimes used off-label to treat other conditions such as obesity and stress.

Testosterone undecanoate is a testosterone replacement therapy (TRT) that's been shown to help increase muscle mass in men. Testosterone undecanoate was originally designed as a treatment for castration-resistant prostate cancer, but it has since been found to be an effective TRT for increasing muscle gain in men. Testosterone undecanoate can be used alone or in combination with other testosterone therapies, such as testosterone enanthate or cypionate.

Testosterone undecanoate is a testosterone derivative that has been shown to increase muscle gain in users. This drug was originally designed as a treatment for hypogonadism, but it has since been found to be an effective muscle builder in its own right.

Clinical data

Indication

Testosterone undecanoate is indicated for testosterone replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone. These conditions include:

Congenital or acquired primary hypogonadism: testicular failure due to cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, orchiectomy, Klinefelter's syndrome, chemotherapy, or toxic damage from alcohol or heavy metals. These men usually have low serum testosterone concentrations and gonadotropins (follicle-stimulating hormone FSH, luteinizing hormone LH) above the normal range.

Congenital or acquired hypogonadotropic hypogonadism: gonadotropin or luteinizing hormone-releasing hormone (LHRH) deficiency or pituitary-hypothalamic injury from tumors, trauma, or radiation. These men have low testosterone serum concentrations but have gonadotropins in the normal or low range.

Testosterone undecanoate is not used to treat age-related hypogonadism.

Mechanism of action

Testosterone is a critical male sex hormone that is responsible for the normal growth and development of the male sex organs and the maintenance of secondary sex characteristics, such as the growth and maturation of male sex organs, the development of male hair distribution, vocal cord thickening, and alterations in body musculature and fat distribution. Male hypogonadism, resulting from insufficient testosterone secretion, has two main etiologies: primary hypogonadism is caused by defects in the gonads, whereas secondary hypogonadism is the failure of the hypothalamus (or pituitary) to produce sufficient gonadotropins (FSH and LH).

In the circulation, testosterone undecanoate is cleaved by endogenous non-specific esterases to release testosterone, the active component of the compound. The undecanoate side chain is pharmacologically inactive. Testosterone can be further converted by 5α reductase to its more biologically active form, dihydrotestosterone (DHT). The actions of testosterone and DHT are mediated via androgen receptor, which is widely expressed in many tissues, including the bone, muscle, prostate, and adipose tissue. Testosterone binds to androgen receptors with high affinity and regulates target gene transcription involved in the normal growth and development of the male sex organs and the maintenance of secondary sex characteristics.Testosterone can cause improved sexual function, increased lean body mass, bone density, erythropoiesis, prostate size, and changes in lipid profiles.

Testosterone Undecanoate Works?

There was an idea to produce an anabolic androgenic oral steroid that could be used for men with low testosterone and the product seemed to achieve what it was supposed to. Nonetheless, this product didn't got too popular, because topicals (such as androgel) and especially injectable testosterones are considered much more helpful.

The product is not going through the liver unlike other oral steroids – but this stuff is going through the lymphatic system. This is what avoids the steroid from being eliminated by the liver and enter the blood stream. This is the difference between Testosterone Undecanoate and other oral steroids that are methylated or 17AA.

As soon as it enters the blood stream – the product is working the exact same way as any other testosterone. Some benefits of boosting the testosterone levels include: better sleep and boosted libido. This stuff is a great mood and confidence improver for men but most importantly – it helps you to lose fat and to gain muscles.

What is Testosterone Undecanoate Used For?

Testosterone is the primary male hormone and is responsible for many man like features such as losing fat, muscle and strength gaining, facial hair growth and others.

In medical settings, the product is given to those people who are suffering from low testosterone production but for bodybuilders, it is offering as a performance enhancing drug. But the product is not very widely used because it is considered weak.

Anyway, the product is going to have a positive effect on workouts, on libido and on recovery, but that's only when this stuff is used in higher doses. The good news is that this product can be used for treating low testosterone or as a performance enhancer product without damaging your liver.

Testosterone Undecanoate is most often used by bodybuilders who do not want to inject the product for whatever the reason or use the topical product because of whatever the reason (most often they include site injection pain, allergies to topicals or others).

Although this form of testosterone is used as a PED (performance enhancer drug) – it is not recommended to use any testosterone undecanoate products alone because the stuff is too weak to see any results. The product is going to do a great job when combined so better to stack it.

Testosterone Undecanoate Side Effects

It was earlier mentioned the fact that testosterone undecanoate (Andriol or whatever other product) is a product that is very weak compared to other testosterone versions. This means that the side effects profile are very low with this product either.

Nonetheless, the side effects are pretty much the exact same as with any other testosterone products because in the end – you receive testosterone. This means that estrogenic side effects are possible (aromatization), androgenic side effects are possible, cardiovascular side effects and testosterone suppression.
All of these side effects are unlikely to occur, are dose dependent and they can be easily controlled (by reducing the dosage or by adding a light anti estrogen for dealing with estrogenic side effects).
