Methyltestosterone was first described in 1935, and was one of the first oral androgens to be used in clinical medicine (it follows mesterolone Proviron, the first oral androgen, by one year). Its main clinical use at the time of development was as an oral medication to replace testosterone (and its anabolic and/or androgenic activity) in males when endogenous levels were insufficient (Andropause), although the drug was adopted for a number of other uses over the years as well. These include the treatment of cryptorchidism (undescended testicles), breast cancer in postmenopausal women, excessive lactation and breast pain after pregnancy in mothers not nursing, osteoporosis, and, more recently, female menopause (supporting the overall energy and sexual interest of the patient).
In addition to standard tablets and capsules, methyltestosterone has also been commercially prepared in sublingual or buccal tablets. Metandren Linguets from Ciba Pharmaceutical Company were perhaps the most recognized, and were popularly sold from the 1950’s to 1990’s. These tablets were placed under the tongue or between the gum and cheek and left to dissolve, delivering the drug to circulation via the mucous membranes, bypassing the liver. Sublingual or buccal intake approximately doubles the bioavailability of methyltestosterone, and also provides peak levels of drug rapidly (approximately 1 hour after dosing instead of 2 hours). Although Ciba’s Metandren Linguets are no longer commercially available, numerous other sublingual/buccal Methyltestosterone tablets are still in production today.
Methyltestosterone remains a controversial steroid. Although it has a long history, and arguably a justifiable safety record, it is no longer widely used, and is even being withdrawn from many drug markets. The German Endocrine Society made an official statement that methyltestosterone was obsolete in 1981, and the drug would be removed from German pharmacies some seven years later. Most European nations followed suit. The drug remains available in the United States, although most clinicians generally find it to be a poor choice and don’t prescribe it. Its potential hepatotoxicity is usually cited as a reason, especially when long-term androgen therapy is contemplated. The one exception seems to be the growing interest in using oral Methyltestosterone in low doses to treat female menopause. Early success with Estratest (Solvay) seems to indicate future expansion for this application. Although many markets no longer produce this drug, especially as a single-ingredient product, Methyltestosterone remains widely produced in many others.
How is Methyltestosterone Supplied
Methyltestosterone is widely available in human drug markets. Composition and dosage may vary by country and manufacturer.
Structural Characteristics of Methyltestosterone
Methyltestosterone is a modified form of testosterone. It differs by the addition of a methyl group at carbon 17-alpha, which helps protect the hormone during oral administration. As is typical with c17-alpha alkylation, the resulting steroid has lower anabolic activity than its parent testosterone.
Methyltestosterone Side Effects (Estrogenic)
Methyltestosterone is aromatized by the body, and is highly estrogenic due to its conversion to 17-alpha methylestradiol, a synthetic estrogen with high biological activity. 17-alpha methylation actually slows the rate of aromatization, although the potent nature of 17- methylestradiol more than compensates for this. Gynecomastia is often a concern during treatment, and may present itself quite early into a cycle (particularly when higher doses are used). At the same time water retention can become a problem, causing a notable loss of muscle definition as both subcutaneous water retention and fat levels build. To avoid strong estrogenic side effects, it may be necessary to use an anti-estrogen such as Nolvadex. One may alternately use an aromatase inhibitor like Arimidex (anastrozole), which is a more effective remedy for estrogen control. Aromatase inhibitors, however, can be quite expensive in comparison to standard estrogen maintenance therapies, and may also have negative effects on blood lipids.
MethyltestosteroneSide Effects (Androgenic)
Methyltestosterone is classified as an androgen. Androgenic side effects are common with this substance, and may include bouts of oily skin, acne, and body/facial hair growth. Higher doses are more likely to cause such side effects. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Those genetically prone to male pattern hair loss may wish to opt for a milder, less androgenic, anabolic steroid. As a potent androgen, this steroid may also increase aggressiveness. Women are additionally warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. Like testosterone, methyltestosterone converts to a more potent steroid via interaction with the 5- alpha reductase enzyme, in this case 17-alpha-methyldihydrotestosterone. The relative androgenicity of methyltestosterone may be reduced, although not completely eliminated, by the concurrent use of finasteride or dutasteride.
Methyltestosterone Side Effects (Hepatotoxicity)
Methyltestosterone is a c17-alpha alkylated compound. This alteration protects the drug from deactivation by the liver, allowing a very high percentage of the drug entry into the bloodstream following oral administration. C17-alpha alkylated anabolic/androgenic steroids can be hepatotoxic. Prolonged or high exposure may result in liver damage. In rare instances life-threatening dysfunction may develop. It is advisable to visit a physician periodically during each cycle to monitor liver function and overall health. Intake of c17-alpha alkylated steroids is commonly limited to 6-8 weeks, in an effort to avoid escalating liver strain.
Methyltestosterone was the first oral steroid linked to hepatic damage. This may be, in part, related to the early widespread use of the compound, as the drug generally displays acceptable safety when used in clinically prescribed dosages (serious liver toxicity cannot be completely excluded, however, even at clinical doses). When taken at a dose of 30 mg daily for 5 weeks, hepatotoxicity, as measured by bromosulphalein (BSP) retention, was low in one study. In a separate investigation, a majority of patients noticed significant BSP retention after only 2 weeks of therapy with 67mg daily. Severe liver complications are rare given the periodic nature in which most people use oral anabolic/androgenic steroids, although cannot be excluded with methyltestosterone, especially with high doses and/or prolonged administration periods.
Methyltestosterone Side Effects (Cardiovascular)
Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism.
Methyltestosterone has a strong effect on the hepatic management of cholesterol due to its structural resistance to liver breakdown and route of administration. Studies have demonstrated an approximate 35% decrease in HDL cholesterol and a 30% increase in LDL cholesterol with 40 mg per day.531 These changes occurred within 2-4 weeks of the initiation of therapy, and persisted for 2 weeks after discontinuation of the drug. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.
To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.
Methyltestosterone Side Effects (Testosterone Suppression)
All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.
Methyltestosterone Administration (General)
Studies have shown that taking an oral anabolic steroid with food may decrease its bioavailability. This is caused by the fat-soluble nature of steroid hormones, which can allow some of the drug to dissolve with undigested dietary fat, reducing its absorption from the gastrointestinal tract. For maximum utilization, this steroid should be taken on an empty stomach.
Methyltestosterone Administration (Men)
To treat androgen insufficiency, prescribing guidelines call for a daily dosage of 10-40 mg. The dose is reduced by 50% when administered in sublingual or buccal form. The drug would be used for extended periods so long as the patent’s laboratory results (hepatotoxicity, serum lipids, etc.) do not necessitate its discontinuance.
When used for physique- or performance-enhancing purposes, a daily dosage of 10-50 mg is most commonly used, taken in cycles lasting no more than 6-8 weeks in length. Methyltestosterone is most commonly used not as an anabolic, but to stimulate aggression in the user. Powerlifters, bodybuilders, and competitive athletes often attempt to harness this effect, looking for extra intensity in a training session or competition.
Aside from this, Methyltestosterone offers little except side effects. It is quite toxic, elevating liver enzymes and causing acne, gynecomastia, aggression, and water retention quite easily. Were one to tolerate these side effects, methyltestosterone will offer only poor quality (bulky) gains. One should also be prepared for a substantial loss of size and bodyweight at the conclusion of each cycle with methyltestosterone, due to the high level of water excretion once the drug is discontinued (during administration water retention will account for a considerable percentage of the total weight gain).
Methyltestosterone Administration (Women)
Methyltestosterone is not widely used with women in clinical medicine. When applied, it is most often used as a secondary medication during inoperable breast cancer, when other therapies have failed to produce a desirable effect. The dosage used for this application can be as high as 200 mg per day.
Low doses of methyltestosterone have been used in recent years to treat the symptoms of menopause. An example is the product Estratest, which contains esterified estrogens and 2.5 mg of methyltestosterone. A dosage of 1 tablet per day may improve energy, libido, and overall wellness of the patient, as well as combat osteoporosis (while estrogen replacement may halt calcium loss in the bones, testosterone tends to increase calcium stores). Methyltestosterone is generally not recommended for women for physique- or performance-enhancing purposes due to its strong androgenic nature and tendency to produce virilizing side effects.
Pharmaceutical preparations containing methyltestosterone are fairly limited. In reviewing some of the remaining products and changes on the global pharmaceutical market, we have made the following observations.
Methyltestosterone remains available in the United States. It is sold under the brand names Android tablets and Testred capsules from Valeant Pharmaceuticals. A generic is also available from Impax Labs.
Aburaihan makes a generic methyltestosterone product in Iran. It comes in 25 mg tablets, with 10 sealed in each foil and plastic blister.
Magnus Pharmaceuticals makes the product Methyltestosterone primarily for the EU and UK markets. Due to fake products appearing on the market, Magnus offers an online checker that lets steroid users verify their product originality.
Methyltestosterone is an orally active high androgenic steroid with a very short active life of about 6-8 hours. It is a c17-Alfa alkylated steroid molecule. This means a methyl group has been added to the c-17-Alfa position of the testosterone molecule to slow deactivation of the active substance by the liver. This makes methyltestosterone highly live toxic. This testosterone aromatizes more easily to estrogens than its injection form cousins due to P-450 enzyme activity that occurs during intestinal and liver metabolism. Most of the initial weight gained from the use of this drug was water weight. Though a quick (an hour!) increase in strength and confidence was often realized by athletes during administration the gains were very short term as they disappeared soon after use was discontinued. High blood pressure, nose bleeds, seriously aggressive behavior, gyno, and sodium retention are common. I could not think of any good use for this drug in bodybuilding.
Unfortunately, methyltest is the most common used substitution drug in bogus oral steroids. (Perhaps this explains all the gyno from even low dosage use of Anadrol-50 reported) Serious aggression results in some users (most).
I once stood in a Department of Motor Vehicles (DMV) line with a heavy user. To say the least, no one deserves him more than the DMV, IRS, and bank employees. I actually enjoyed the department of motor vehicles for once.
Methyltestosterone was reported used commonly by strength oriented athletes and usually with co-committent administration of a high anabolic/low or moderate androgenic drug such as a nandrolone.

Methyltestosterone is an oral form of testosterone. Testosterone it-self is ineffective when taken orally since the greatest part ~f the compound is metabolized and destroyed by the liver during the "first pass" so that at most 5-10% of the compound enters the blood and becomes effective. At a closer look methyltestosterone is a I 7-alpha steroid molecule, which means that a methyl group is added to the C-1 7-alpha position of the molecule. Thus, methyltestosterone is not broken down and deactivated quite as fast by the liver as oral testosterone is. Still, it reaches the blood quickly and has only a low half-life time. Since methyltestosterone, in part, is reabsorbed through the mucous membrane in the mouth, this substance is also avail-able for sublingual intake. Methyltestosterone is a very potent steroid since it has a distinct androgenic effect. In particular, it is used to increase aggressiveness. Powerlifters and weightlifters use it before a heavy workout or a competition since the increased androgenic effect can already be noted one hour after intake and the improved aggressiveness, the increased self-esteem, and the thrust of motivation taking place allow the athlete to lift heavier weights. Those who try it will notice a quick and strong strength gain. The increase in body weight is within normal limits and is mostly due to water retention. The dosage is usually 25-50 mg/day. Methyltest is rarely taken if at all for more than four weeks and women usually do not use it.
Methyltestosterone is a very toxic steroid which can cause many side effects. it especially puts stress on the liver. Since this steroid strongly aromatizes, gynecomastia is one of the most common side effects. The distinct water and salt retention can also increase blood pressure. The androgenic effect re-sults in considerable virilization symptoms in women and acne and AGGRESSIVENESS in men. It is no joking matter to be around someone who works a lot with methyltestosterone. Effects include anti-social behavior, irritability, impatience, tantrums, and forgetfulness or light disturbances in consciousness.
Methyltestosterone is normally readily available on the black market. It is available in tablet, dragee, or capsule form for oral, sublingual or buccal intake. Methyltestosterone is a very low-priced and easily available substance. It is a welcome fact that the athlete does not have to pay much money for it. The 10 mg Androral tablets cost approx. $25 per 100 and the 25 mg version of Teston costs approx. $0.40 per tablet on the black market. The disadvantage is that methylestosterone is the substance most often used in fakes.
Newbies Research Guide referenceThis drug is oral testosterone. It is more androgenic than anabolic. It aromatises easily and is toxic to the liver. This product was developed many years ago and is quite obsolete today. Still many athletes take the drug to promote aggression. This often is a desired effect for powerlifters, or competitive athletes. The drug gets into the system very fast; in just about an hour its androgenic effects can be felt. Powerlifters claim this helps their strength when taken before a workout or contest. This is probably the only use for Metandren as it has not been too great for building size or permanent strength. Still some athletes favor it in a cycle with other anabolics. Average doses have been 20mg to 50mg daily.
