Mesterolone

Proviron (Mesterolone), an anabolic steroid, is particularly interesting. I suspect that it not only acts as an antiaromatase but in an unknown DHT-like anti-estrogenic manner. This might involve estrogen receptor downregulation for example. In any case, aromatase inhibition and/or Clomid don’t seem to give the same effect on appearance and muscle hardness as when Proviron is included. This drug has good binding to the androgen receptor, but in muscle tissue most of it never reaches the androgen receptor because it is enzymatically converted to the diol. Thus, it is not an effective anabolic. It is somewhat effective as an anti-gyno agent, however, and appears to reduce estrogenic bloating if that problem exists. Proviron reduces either levels of estrogen or the effect of estrogen. Thus, it is useful for avoiding gynecomastia, although it probably should not be relied upon as the sole drug for that. It is not hepatotoxic. It has the usual side effects of anabolic/androgenic steroids, with the added effect that it is particularly prone to cause erections. Mesterolone is an orally active, 1-methylated DHT. Like Masteron, but then actually delivered in an oral fashion. DHT is the conversion product of testosterone at the 5-alpha-reductase enzyme, the result being a hormone that is 3 to 4 times as androgenic and is structurally incapable of forming estrogen. One would imagine then that mesterolone would be a perfect drug to enhance strength and add small but completely lean gains to the frame. Unfortunately there is a control mechanism for DHT in the human body. When levels get too high, the 3alpha hydroxysteroid dehydrogenase enzyme converts it to a mostly inactive compound known as 3-alpha (5-alpha-androstan-3alpha,17beta-diol), a prohormone if you will. It can equally convert back to DHT by way of the same enzyme when low levels of DHT are detected. But it means that unless one uses ridiculously high amounts, most of what is administered is quite useless at the height of the androgen receptor in muscle tissue and thus mesterolone is not particularly suited, if at all, to promote muscle hypertrophy. Proviron has four distinct uses in the world of bodybuilding. The first being the result of its structure. It is 5-alpha reduced and not capable of forming estrogen, yet it nonetheless has a much higher affinity for the aromatase enzyme (which converts testosterone to estrogen) than testosterone does. That means in administering it with testosterone or another aromatizable compound, it prevents estrogen build-up because it binds to the aromatase enzyme very strongly, thereby preventing these steroids from interacting with it and forming estrogen. So Mesterolone use has the extreme benefit of reducing estrogenic side-effects and water retention noted with other steroids, and as such still help to provide mostly lean gains. Its also been suggested that it may actually downgrade the actual estrogen receptor making it doubly effective at reducing circulating estrogen levels. The second use is in enhancing the potency of testosterone. Testosterone in the body at normal physiological levels is mostly inactive. As much as 97 or 98 percent of testosterone in that amount is bound to sex hormone binding globulin (SHBG) and albumin, two proteins. In such a form testosterone is mostly inactive. But as with the aromatase enzyme, DHT has a higher affinity for these proteins than testosterone does, so when administered simultaneously the mesterolone will attach to the SHBG and albumin, leaving larger amounts of free testosterone to mediate anabolic activities such as protein synthesis. Another way in which it helps to increase gains. Its also another part of the equation that makes it ineffective on its own, as binding to these proteins too, would render it a non-issue at the androgen receptor. Thirdly, mesterolone is added in pre-contest phases to increase a distinct hardness and muscle density. Probably due to its reduction in circulating estrogen, perhaps due to the downregulating of the estrogen receptor in muscle tissue, it decreases the total water build-up of the body giving its user a much leaner look, and a visual effect of possessing "harder" muscles with more cuts and striations. Proviron is often used as a last-minute secret by a lot of bodybuilders and both actors and models have used it time and again to deliver top shape day in day out, when needed. Like the other methylated DHT compound, drostanolone, mesterolone is particularly potent in achieving this feat. Lastly Proviron is used during a cycle of certain hormones such as nandrolone, with a distinct lack of androgenic nature, or perhaps 5-alpha reduced hormones that don't have the same affinities as DHT does. Such compounds, thinking of trenbolone, nandrolone and such in particular, have been known to decrease libido. Limiting the athlete to perform sexually being the logical result. DHT plays a key role in this process and is therefore administered in conjunction with such steroids to ease or relieve this annoying side-effect. Proviron is also commonly prescribed by doctors to people with low levels of testosterone, or patients with chronic impotence. Its not perceived as a powerful anabolic, but it gets the job done equally well if not better than other anabolic steroids making it a favorite in medical practices due to its lower chance of abuse. Mesterolone is generally well liked nonetheless as it delivers very few side-effects in men. In high doses it can cause some virilization symptoms in women. But because of the high level of deactivation and pre-destination in the system (albumin, SHBG, 3bHSD, aromatase) quite a lot of it, if not all simply never reaches the androgen receptor where it would cause anabolic effects, but also side-effects. So its relatively safe. Doses between 25 and 250 mg per day are used with no adverse effects. 50 mg per day is usually sufficient to be effective in each of the four cases we mentioned up above, so going higher really isn't necessary. Unlike what some suggest or believe, its not advised that Proviron be used when not used in conjunction with another steroid, as it too is quite suppressive of natural testosterone, leading to all sorts of future complications upon discontinuation. Ranging from loss of libido or erectile dysfunction all the way up to infertility. One would not be aware of such dangers because Proviron fulfills most of the functions of normal levels of testosterone. Stacking and Use: Mesterolone is an oral alkylated steroid. If used primarily as an anti-aromatase drug, using it throughout a longer cycle (10-12 weeks) of injectables may elevate liver values a little bit, though much, much less than one would expect with a 17-alpha-alkylated steroid. Eventhough instead of inhibiting gains, mesterolone may actually contribute to gains. So that's a bit of a shame. Its not quite as toxic since its not alkylated in the same fashion, but at the 1 position, which reduces hepatic breakdown, but not like 17-alpha alkylation. The reason for the change of position I assume, is because alkylating at the 17-alpha position has been shown to reduce affinity for sex hormone binding proteins. This would in turn decrease its ability to free testosterone. Nonetheless the delivery rate is quite good. Its taken daily in 50-100 mg doses. The best thing to stack it with is testosterone of course. Its most easily bound to SHBG and albumin, and deactivated for up to 98%. Since the DHT can compete for these structures with higher affinity it would naturally lead to a higher yield of whatever testosterone product you stacked it with. Since DHT levels are notably higher now there is also more stimulation of the androgen receptor causing more strength gains, and because of its affinity for aromatase the overall estrogen level decreases as well. This has as a result that gains are leaner, and once again the overall testosterone yield is increased as less I converted at the aromatase enzyme. It's of course used in other stacks with products such as methandrostenolone, boldenone and nandrolone to reduce estrogenic activity and increase muscle hardness. The addition of proviron makes boldenone a dead lock for a cutting stack and for some may even make it possible to use nandrolone while cutting, although the use of Winstrol or a receptor antagonist in conjunction is wishful as well. The benefit of adding it to a nandrolone stack is that it may also help you reduce the decrease in libido suffered from nandrolone, since the latter is mostly deactivated by 5-alpha reductase, an enzyme that makes other hormones more androgenic. Proviron is an anti-aromatase, so obviously anti-estrogens would be futile and redundant. Blood pressure medication for those prone to hypertension may be wise, as this DHT can increase the blood pressure. Mesterolone (Proviron) is a synthetic, orally effective androgen which does not have any anabolic characteristics. Mesterolone (Proviron) is used in school medicine to ease or cure disturbances eaused by a deficiency of male sex hormones. Many athletes, for this reason, often use Mesterolone (Proviron) at the end of a steroid treatment in order to increase the reduced testosterone production. This, however is not a good idea since Mesterolone (Proviron) has no effect on the body's own testosterone production but-as mentioned in the beginning-only reduces or completely eliminates the dysfunctions caused by the testosterone deficiency. These are in particular impotence which is mostly caused by an androgen deficiency that can occur after the discontinuance of steroids, and infertility which manifests itself in a reduced sperm count and a reduced sperm quality. Mesterolone (Proviron) is therefore taken during a steroid administration or after discontinuing the use of the steroids, to eliminate a possible impotency or a reduced sexual interest. This, however does not contribute to the maintainance of strength and muscle m..

Many athletes, for this reason, often use Proviron at the end of a steroid treatment in order to increase the reduced testosterone production.

These are in particular impotence which is mostly caused by an androgen deficiency that can occur after the discontinuance of steroids, and infertility which manifests itself in a reduced sperm count and a reduced sperm quality. Proviron is therefore taken during a steroid administration or after discontinuing the use of the steroids, to eliminate a possible impotency or a reduced sexual interest. This, however does not contribute to the maintenance of strength and muscle mass after the treatment.Some competitive bodybuilders will also add Mesterolone to their pre-contest preparation as many believe that it will improve muscle density and hardness. This could be attributed to the ability of the compound to decrease water retention and reduce the amount of circulating estrogen in the body, similar to many other androgenic compounds. However, as discussed earlier, there are several other drugs that could be substituted for mesterolone that are much more effective for this prupose.Many steroid users who have had adverse reactions to testosterone, or otherwise do not wish to use testosterone in their cycle, will often add Mesterolone to their cycles for it's ability to increase the libido of a user. Often times when a user does not include testosterone, or simply not enough testosterone in relation to the other compounds that he is using, libido will be reduced and including Mesterolone may help alleviate this. Obviously, the dihydrotestosterone effect of the compound plays a key role in this process.HOW DOES IT WORKS?This drug is also favored by many during contest preparations, when a lower estrogen/high androgen level is particularly sought after. This is especially beneficial when anabolics like Winstrol, Oxandrolone and Primobolan are being used alone, as the androgenic content of these drugs is relatively low. Proviron can supplement a wellneeded androgen, and bring about an increase in the hardness and density of the muscles. Women in particular find a single 25 mg tablet will efficiently shift the androgen/estrogen ratio, and can have a great impact on the physique. Since this is such a strong androgen however, extreme caution should be taken with administration. Higher dosages clearly have the potential to cause virilization symptoms quite readily. For this reason females will rarely take more than one tablet per day, and limit the length of intake to no longer than four or five weeks. One tablet used in conjunction with 10 or 20 mg of Nolvadex can be even more efficient for muscle hardening, creating an environment where the body is much more inclined to burn off extra body fat (especially in female trouble areas like the hips and thighs).Proviron is therefore taken during a steroid administration or after discontinuing the use of the steroids, to eliminate a possible impotency or a reduced sexual interest. This, however does not contribute to the maintainance of strength and muscle mass after the treatment.There are other better suited compounds for this like HCG and Clomid. For this reason Proviron is unfortunately cunsidered by many to be a useless and unnecessary compound.The majority of male users will find that dosing in the range of 25 to 100 milligrams per day of mesterolone will be enough to acheive their desired results. Females most often remain at about 25 milligrams per day, but many have experimented with levels far higher. Due to the active life of the compound, splitting the dosage of the drug so that it can be taken twice per day is beneficial, but the effects of the compound should remain for a full twenty four hours so it is not completely necessary.Due to the fact that many other compounds are available that are much more potent and effective than Mesterolone for the same purposes, it is seemingly unnecessary to increase a user's dosage far higher than 100 mgs per day. Instead one would most likely be better served to switch compounds are try a much more potent drug if the desired results are not acheived.SIDE EFFECTS:The side effects of Proviron in men are low at a dosage of 2-3 tablets/day so that Proviron, taken for example in combination with a steroid cycle, can be used comparatively without risk over several weeks. Since it is well-tolerated by the liver liver dysfunctions do not occur in the given dosages. For athletes who are used to acting under the motto "more is better" the intake of Proviron could have a paradoxical effect. The most common side effect of Proviron or in this case, secondary symptom is in part a distinct sexual over-stimulation and in some cases continuous penis erection. Since this condition can be painful and lead to possible damages, a lower dosage or discontinuing the compound are the only sensible solutions. Female athletes should use it with caution since possible androgenic side effects cannot be excluded. Women who want to give Proviron a try should not take more than one 25 mg tablet per day. Higher dosages and periods of intake of more than four weeks considerably increase the risk of virilization symptoms. Female athletes who have no difficulties with this drug obtain good results with 25 mg Proviron/day and 20 mg Tamoxifen/day and, in combination with a diet, report an accelerated fat breakdown and continuously harder muscles.Like any drug, Proviron also is associated with some rare side effects. While the side effects do not occur in all individuals, they are quite disturbing. The side effects include: painful erections, loss of libido, general fatigue, deepening of voice, hair growth, acne, oily skin. ..
