In the pharmaceutical market, there are many different forms and types of testosterone. But almost all of them are injectable, in the form of an oil solution. The main problem that prevented the creation of testosterone in tablets was that the molecule of substance is destroyed in the liver by special enzymes. Thus, to give stability to the form, there was simply no other option, except for the modification of the molecule itself. And this was done: first (in the middle of the last century) methyltestosterone appeared on the market, and then (in the early 80’s) and testosterone undecanoate (Testosterone Undecanoate).
The main active substance – testosterone, is characterized by pronounced anabolic effects. In men, it is produced by the adrenal cortex and Leydig cells, in women – only by the adrenal cortex. Testosterone is a product of peripheral metabolism and a basic substance for the production of many steroids. It should be noted that the hormone itself has low biological activity and weakly binds to androgen receptors. Testosterone is modified with a special enzyme – 5-alpha-reductase, and converted into a biologically active form – dihydrotestosterone. According to the studies conducted, testosterone undecanoate is nontoxic for the liver, since it does not enter the bloodstream when it is sucked, but into the lymph through which it enters the common circulatory system. Steroid does not show estrogenic activity, users do not face fluid accumulation and gynecomastia. Suppression of the production of own testosterone is not very pronounced.
How to take testosterone tablets undecanoate
The course of testosterone undecanoate is made on the basis of such factors as the previous pharmacological experience of the athlete, his physiological state, goals, contraindications, etc. Begin the appointment should be, after consulting with the doctor. And although dosages are determined individually, taking less than 240 milligrams of steroid per day does not make sense. But too large doses are undesirable, since they increase the risk of negative reactions.
The tablet form is safe enough, but the following side effects from testosterone undecanoate tablets are possible: increased blood pressure, excessive irritability, agitation, aggression, acne, alopecia, or hair follicles.
Reviews about testosterone undecanoate
Professionals who used testosterone in tablets in their daily practice note that its effect is not sufficient to allow it to be limited to a solo course. Reviews of testosterone undecanoate from experienced athletes indicate low bioavailability (about 7%) and the advisability of connecting more powerful AAS. To improve the mass-selective action, it is recommended to combine undecanoate with Nandrolone. Bodybuilders with experience do not consider a steroid a priority for increasing strength and muscle mass gain.
Testimonials about testosterone undecanoate beginners are more loyal. Opinions boil down to the fact that the steroid is not bad for the first course of anabolic and androgenic drugs. Attraction of relative safety, in particular – low level of suppression of own testosterone. In addition, the solo course of undecanoate does not require PBC.
