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 substance molecule 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 80s) and 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 base 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 by 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, but into the lymph through which it enters the common circulatory system. The 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.
Action of Testosterone Undecanoate
- Increase in muscle mass.
- Regulation of development of male sex hormones and some secondary sexual characteristics (male-type hair, low voice, male facial features, etc.).
- Improvement of phosphorus metabolism and nitrogen balance.
- Providing sexual behavior and spermatogenesis.
- Increased motivation.
- Improved mood.
- Stimulation of erythrocyte production. Testosterone undecanoate promotes an increase in the oxygen content of the blood, and as a result – endurance.
As practice shows, testosterone decanoate in tablets reduces the level of endogenous testosterone much less than injectable analogues. In general, the oral version of the steroid has a lower probability of side effects and is safe (but it acts on the body is not so pronounced).
How to take tablets of Testosterone 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 dosages are undesirable, since they increase the risk of negative reactions.
Tablets that increase testosterone in men should be taken with food, while the food should not contain too much fat, so that absorption through the lymphatic system is maximized. It should be noted that when taking tablets on an empty stomach, the absorption will be very low.
If the patient is interested in the question of how to increase testosterone in men, the tablets should be taken at least twice a day to maintain a sufficient level of the hormone.
In order to increase the level of androgens, the drug is taken in a dose of 120-160 mg daily for 2-3 weeks.
Pronounced anabolic effects are noted only when high doses of the drug are used, that is, at least 240 mg daily. It should be understood that the risk of side effects is significantly increased.
Course of testosterone in tablets
Well, if you have already decided to try the drug, testosterone in tablets (UNDERKANOAT) needs to be combined with another anabolic steroid – NANDROLON. Those. UNDECANATE + NANDROLON. This bundle is in principle more effective than just a solo. Bundle has virtually no side effects (if not exceed the dose). But as practice shows, in order to feel the anabolic effects of taking the drug, you need to use high doses of UNDERKANOAT (androxone) about 240 mg per day. But this leads to the occurrence of side effects.
The tablet form is safe enough, but nevertheless the following side effects from testosterone undecanoate tablets are possible: increased blood pressure, excessive irritability, agitation, aggression, acne, alopecia, or hair follicles.
Studies have shown that testosterone undecanoate does not have a toxic effect on the liver, because when it is absorbed from the digestive tract, it enters the lymph (and not into the bloodstream), with the current through the general lymphatic duct entering the common circulatory system, so the liver passes. In the body, undecanoate is converted into dihydrotestosterone, the active metabolite of testosterone, that is, in fact this substance is a prohormone. In view of the fact that dihydrotestosterone does not undergo aromatization, it does not cause an increase in the level of female sex hormones – estrogens, and therefore does not lead to the development of gynecomastia and the accumulation of fluid in the body. In addition, it was found that testosterone in tablets (Androxon or Andriol) does not cause significant suppression of the production of endogenous (secreted in testicles) testosterone.
It would seem that the tablet version of the hormone does not have significant deficiencies and pretends to be the best anabolic agent, however in practice testosterone undecanoate appears to be a rather weak androgenic drug. Athletes who used it in their training practice note only a slight increase in muscle mass, even with the use of large doses of the drug. It was found that the drug has a rather low bioavailability – about 7%. In addition, it was noted that the course of testosterone undecanoate causes a significant increase in libido (at the time of admission) and frequent erections. A few days after the course, as well as in the case of other androgenic steroids, there is a decline in these indicators due to the suppression of endogenous secretion of male sex hormones.
To obtain good results in the collection of muscle mass, testosterone in tablets should be combined with a steroid such as Nandrolone. The combination of testosterone undecanoate + nandrolone is quite effective and has virtually no side effects. Overall, this drug is not the preferred choice in bodybuilding for muscle mass gaining or relief or powerlifting to increase strength.
Caution should be used to treat boys during the transition period, because there may be side effects associated with too active sexual development. It is important that the expediency of using the drug is determined exclusively by a specialist.
In people suffering from certain chronic diseases (epilepsy, migraine, heart failure), these diseases can worsen during the reception of the male hormone.
With care, androgens are assigned to people suffering from benign prostatic hyperplasia.
If the patient has side effects associated with androgen dependence, it is necessary to stop treatment, and resume it after the disappearance of such symptoms.
Reviews about testosterone undecanoate
Professionals who used testosterone in tablets in their daily practice note that its effect is insufficient 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.
