Proviron (DHT, Masterlone, Masterolone, Mesterolone)

Proviron (Masterolone) er en oral form av 1-metylert DHT (methyl-dihydrotestosteron). 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.

Mannlige idrettsutøvere bør foretrekke Proviron fremfor Nolvadex. Med Proviron oppnår atleten bedre muskelhardhet, ettersom androgennivået økes og konsentrasjonen av østrogen forblir lav. Dette er spesielt tydelig når man forbereder seg på en konkurranse i forbindelse med kosthold.

Imidlertid bør man være klar over at tap av styrke forårsaket av redusert naturlig testosteronproduksjon etter syklusen ikke er kurert. Idrettsutøver bør bruke andre medisiner som HCG og clomiphen for det.

Dosering og bruk

Proviron er veldig effektiv forbindelse, daglig dose på 50 mg er tilstrekkelig, selv om noen menn gjør 100 og til og med 250 mg / dag. Idrettsutøver tar normalt en 25 mg tablett om morgenen - og den andre om kvelden. I noen tilfeller er til og med en 25 mg tablett nok. Kombinasjon av 50 mg Proviron per dag og 20 mg Nolvadex per dag resulterer i nesten fullstendig undertrykkelse av østrogen. Husk imidlertid at østrogen ikke er absolutt ondt, det spiller også en viktig rolle i muskelbygging. Fullstendig undertrykkelse av østrogen betyr lavere gevinster, så man bør holde en balanse og redusere østrogennivået bare til det punktet når det ikke gir noen bivirkninger, men fremdeles gir positive.

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.

Stabling

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.

Selvfølgelig brukes proviron også i mange andre stabler, for eksempel med dianabol (methandrostenolone), boldenonundekanoat og nandrolon for å redusere østrogenrelaterte aktiviteter øker muskelhardheten.

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.

Bivirkninger med 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.

Det er ingen effekt på frekvensen LH (luteiniserende hormon) og FSH (stimulerende hormon) i en dose på 100-150 mg / dag.

Proviron erstatter ikke Clomid som hormonbehandling, men forårsaker heller ikke problemer.

Virkningen av mesterolon gir ingen endringer i nivåene av steroider, skjoldbruskhormoner, gonadotropiner og prolaktin.

Bruk av kvinner

Kvinnelige idrettsutøvere bør være forsiktige når de bruker Proviron, siden det ikke utelukker alle mulige androgene bivirkninger. Kvinner rådes til ikke å ta mer enn en 25 mg tablett / dag. Høyere doser og langvarig bruk i mer enn 4 uker øker risikoen for virilisering. Kvinnelige idrettsutøvere som ikke har problemer med Proviron, oppnår gode resultater ved å ta 25 mg Proviron per dag og 20 mg Nolvadex per dag. De sier at det i kombinasjon med en diett akselererer fettforbrenning og rask herding av muskler.

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.
