Transdermal patches (adhesive patches placed on the skin) may also be used to deliver a steady dose through the skin and into the bloodstream. Testosterone-containing creams and gels that are applied daily to the skin are also available, but absorption is inefficient (roughly 10%, varying between individuals) and these treatments tend to be more expensive. Individuals who are especially physically active and/or bathe often may not be good candidates, since the medication can be washed off and may take up to six hours to be fully absorbed. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses. Injection is the most common method used by individuals administering AAS for non-medical purposes. 
Proviron is a synthetic, orally active androgen, but too weak anabolic properties. DHT is a product derived from testosterone by treatment with 5-alpha - reducing enzymes. In medicine Proviron is used in a shortage of male sex hormone. Therefore, the athletes receive it at the end of the steroid cycle in order to increase its reduced testosterone level. Unfortunately, this is wrong, since Proviron has no effect on testosterone production after a steroid cycle. Its use to increase spermatogenesis can be used only during a cycle, but the effect is still very small.
One could say that there is no point of using Proviron to upload or maintain muscle mass, as well as to increase testosterone levels, but there is something else that makes it very valuable preparation for any athlete. It is precisely his strong anti-estrogenic effect. Proviron completely prevents aromatization of steroids themselves. It stops water retention in the body, and very unwanted gynecomastia. The strong antiestrogenic Proviron prevents the occurrence of gynecomastia even after stopping steroid cycle, in contrast to the preparation tamoxifen, which will prevent not aromatization of steroids.
We can say that Proviron stops aromatization in the bud, Nolvadex and fights the symptoms.
Besides that hinders the process of deodorization Proviron them and other attractive countries for bodybuilders. One of the most important is that it can significantly increase the potential of testosterone in the body. Most of the testosterone in the human body (97 -98%) is the idle because it is associated with globolin (SHBG) and albumin. However, when in the organism enters Proviron he joins these proteins and a greater amount of testosterone remains free. This helps to improve performance and protein synthesis.
With Proviron athletes increase the effects of steroids, since the level of androgen remains high, and the estrogen is kept constant low. This property Proviron particularly shows up in preparation for a competition when a diet.
Proviron works well under normal dosage of 25 mg. daily, but some athletes prefer to take 25 mg. in the morning and 25 mg. night. And if 50 mg. Proviron daily are combined with 20 mg. Nolvadex estrogen flavor is completely stopped. As a side effect it can be mentioned that the loaded Provironat liver gently, but in the case that does not exceed dosages, there is no danger of any serious problems. If, in individual cases occur frequent or prolonged erections, the dose should be reduced or the treatment should be discontinued in order to avoid damage to the penis. In conclusion, one can say that if you are taking anabolic steroids, which are easily flavored to estrogen, must accept and Proviron to prevent Gynecomastia.
