Proviron (DHT, Masterlone, Masterolone, Mesterolone)

Proviron (Masterolone) é uma forma oral de 1-metilado DHT (methyl-dihidrotestosterona). This is very strong androgen which is 3-4 times more effective than “normal” testosterone, it possesses no anabolic characteristics and no capabilities of converting to estrogen. One would imagine then that mesterolone would be a perfect drug to enhance strength and achieve some progress. Unfortunately, there is a control mechanism for DHT in the body. When levels get too high it is being converted to an inactive compound. This inactive compound can equally be transformed in the opposite direction to dihydrotestosterone by the same enzyme when low levels of DHT are detected. But this means that very large amounts of this substance are useless to achieve muscle hypertrophy. Very common usage is fighting estrogen just like with Tamoxifen Citrate or Clomiphen. Provironhas four distinct applications in bodybuilding.First of all, proviron serves as anti-estrogen, it prevents  aromatization of other steroids as a process and also partially blocks estrogen receptors. In this instance its action differs from tamoxifen, which only blocks  estrogen receptors. Thus side effects such as gynecomastia and increased water retention are successfully eliminated. Proviron hits the root of the problem, while Tamoxifen fights only symptoms and should be used for longer period until all excessive estrogens are washed out of the body.
The second application is based on expanding the capacity of testosterone. 97-98% of testosterone in the body of a healthy person is inactive and bound to certain proteins. Proviron in this case replaces testosterone, thus more of latter is being released into the blood and helps to build muscle mass.

Thirdly, mesterolone is added in pre-competition cycles to increase the rigidity and quality muscle volume. It also decreases water retention in the body, giving the user a visual effect of a dry, high-quality, lean muscles. Proviron is often used not only among bodybuilders, but even the actors and models, who use it to acquire the necessary sportive form  before the shooting. Just like the another methylated DHT structure called drostanolone, mesterolone is particularly strong in achieving this effect.Finally, Proviron is used for recovery of sexual activity during the cycles of steroids such as trenbolone and nandrolone, which decrease libido. Proviron is also commonly prescribed by doctors for people with low levels of testosterone, or patients with chronic impotence.Mesterolone is preferred by many athletes because it has virtually no side effects on men. In large doses it can cause some virilization symptoms in women. Doses of 25 and 250 mg per day shall be applied without adverse effects. 50 mg per day is usually sufficient to reach goals for any of four applications that we mentioned above. Thus, there is no need to increase the dose.

Atletas do sexo masculino devem preferir Proviron a Nolvadex. Com Proviron o atleta consegue uma melhor dureza muscular, pois o nível de andrógeno é aumentado e a concentração de estrógeno permanece baixa. Isso é particularmente evidente ao se preparar para uma competição em conjunto com a dieta.

No entanto, deve-se estar ciente de que a perda de força causada pela diminuição da produção natural de testosterona após o ciclo não é curada. O atleta deve usar outras drogas como HCG e clomifeno para isso.

Dosagem e uso

Proviron é um composto muito eficaz, a dosagem diária de 50 mg é suficiente, embora alguns homens façam 100 e até 250 mg / dia. O atleta normalmente toma um comprimido de 25 mg de manhã e outro à noite. Em alguns casos, mesmo um comprimido de 25 mg é suficiente. O combo de 50 mg de Proviron por dia e 20 mg de Nolvadex por dia resulta na supressão quase completa do estrogênio. No entanto, tenha em mente que o estrogênio não é o Mal absoluto, ele também desempenha um papel importante na construção muscular. A supressão completa do estrogênio significa ganhos mais baixos, portanto, deve-se manter o equilíbrio e diminuir o nível de estrogênio apenas até o ponto em que não haja efeitos colaterais, mas ainda produza efeitos positivos.

In the past athletes used it throughout the whole season to make dry and fit outlook all the time, however, we don’t advice such practices nowadays. Clenbuterol / albuterol (ventolin) can do the same but with less side effects.

Empilhamento

Proviron is an oral 1-alpha-alkylated substance mostly used as  an anti-estrogen drug. Mesterolone may actually contribute to gains.  It is taken daily in 50-100 mg doses.

The best stack is certainly with testosterone. This results in qualitive, lean gains as free testosterone levels are increased and less converted to estrogen.

Claro, o proviron também é usado em muitas outras pilhas, por exemplo com dianabol (metandrostenolona), undecanoato de boldenona e nandrolona, a fim de reduzir as atividades relacionadas ao estrogênio e aumentar a dureza muscular.

Combo of proviron with boldenone makes dead lock for a cutting stack. Sometimes it’s even become possible to add deca into that cutting stack, preferably along with winstrol. It’s good idea to use proviron with nandrolone, because nandrolone temporarily decreases libido.

Efeitos colaterais com proviron

When athlete do it for more than 10-12 weeks it may slightly increase liver values although in general proviron is well tolerated by it. Side effects of Proviron for men with a dose of 2 – 3 tablets are very small, so that Proviron, in combination with a steroid cycle can be relatively safe to be taken over several weeks.

DHT can increase blood pressure. High dosages may lead to premature baldness and sexual overstimulation, which leads to prolonged erection. Since this state is painful and can cause penis damage, it makes sense to reduce the dose or discontinue its use altogether.

Only 34% of recipients observe minor decrease in endocrine glands function. Proviron did not stop work of HPTA (glands) for noone who took the drug for a year at a dose of 150 mg / day. In general it’s pretty safe and has little impact on the work of HPTA.

Não há efeito na taxa de LH (hormônio luteinizante) e FSH (hormônio estimulante) na dosagem de 100-150 mg / dia.

Proviron não substitui o Clomid como terapia hormonal, mas também não causa problemas.

O impacto do mesterolone não produz alterações nos níveis de esteroides, hormônios tireoidianos, gonadotrofinas e prolactina.

Uso feminino

Atletas do sexo feminino devem ser cautelosos ao usar Proviron, uma vez que não exclui todos os possíveis efeitos colaterais androgênicos. As mulheres são aconselhadas a não tomar mais do que um comprimido de 25 mg / dia. Doses mais altas e uso prolongado por mais de 4 semanas aumentam os riscos de virilização. Atletas do sexo feminino que não têm problemas com Proviron obtêm bons resultados tomando 25 mg de Proviron por dia e 20 mg de Nolvadex por dia. Eles dizem que em combinação com uma dieta acelera a queima de gordura e o rápido endurecimento dos músculos.

Female athletes who naturally have higher estrogen levels,  often add Proviron to steroid cycle, which results in increasing of muscle density. In the past female athletes did proviron whole year in order to look lean, especially before contests and starring. Nowadays, clenbuterol / albuterol do the same work, because they do not cause virilization effects.
