Short-acting drostanolone ester known for its hardening effect and synergy with testosterone. Highly androgenic. Supports the central nervous system.Strength :Muscle Gain :Fat/Water Loss :Side Effects :Keep Gains : Masteron (Masteron Injections) 10 ml Masteron (known as drostanolone propionate) is a slightly anabolic and androgenic steroid that is not aromtized to estrogen. Usually are using those athletes that do speed sports. It is good in gain muscle mass, strength and reduce body fat with not so many side effects. Bodybuilders often are using Masteron who have a low level of fat and wants to improve muscles, and using it at the end of the cycle or before competition. Masteron could be stacked with Winstrol and Testosterone Propionate. Masteron dramatically improve hardness and sharpness of the muscles tissue and appearance of vascularity ready before the competition. In results we can say that it is a steroid used for cutting cycle. Benefits of Masteron Steroid:· Few side effects· Is not an aromatizing steroid· Vascularity· Increase strength of muscle· Good for speed sportsAlso known as: Masteron, Drostanolone, Dromostanolone, Drostanolone Propionate, Drostanolone Enanthate Originally Dromostanolone (abbreviated to Drostanolone) known by trade name Masteron is an injectable oil-based anabolic steroid, derived from Dihydrotestosterone (DHT). It is a member of the DHT-derived family of anabolic steroids. Other known DHT-derivatives include: Winstrol, Anadrol, Anavar, Primobolan, and a few more. Drostanolone (Masteron) is considered a moderate strength anabolic steroid with anabolic rating: 62 - 130 and low androgenic strenght: 25 - 40. There are two different variants of Masteron: Drostanolone PropionateDrostanolone EnanthateAll anabolic steroid analogues and derivatives are derivates of the three natural anabolic steroids found in the human body:TestosteroneDihydrotestosteroneNandroloneBiochemistry of Masteron / Drostanolone Masteron is a modified form of Dihydrotestosterone, with a methyl group at the 2nd carbon (carbon alpha) atom. This modification is responsible for the anabolic strength increase. This methyl group makes it harder for the enzyme 3-hydroxysteroid dehydrogenase to metabolize Masteron. This enzyme is abundantly present in muscle tissue, and is responsible for degrading any DHT into two inactive metabolites: 3-Alpha Androstanediol and 3-Beta Androstanediol. Because of this enzyme DHT is not anabolic in muscle tissue at all. It is believed that if the enzyme 3-hydroxysteroid dehydrogenase was neutralized, DHT would actually be a very powerful anabolic steroid. Drostanolone's methyl group addition makes it imune to this enzyme. Drostanolone is injected into the body as an ester (bonded to either Propionate or Enanthate). Enzymes cleave off the ester from the Masteron molecule - which takes varying amount of time depending on which ester was used. This process causes the gradual release rate and extended half-life of the steroid. Drostanolone Propionate has a half-life of 2.5 days, while Drostanolone Enanthate has a half-life of 10 days. Intended use of Drostanolone / Masteron Masteron was initially marketed as a treatment of female breast cancer. Because it pronounced male characteristics in women and because more effective breast cancer treatments were invented, Drostanolone was gradually phased out. Actual use of Masteron Nowadays Drostanolone is a very popular anabolic steroid used mainly by athletes and bodybuilders. How to use Masteron? Where to inject Drostanolone / Masteron Like other steroids Masteron can be injected into any muscle (if the muscle is big enough). The most popular being buttocks, shoulders and triceps. Masteron cycle compatibility, examples and duration Like majority of steroids, Masteron acts very well in combination with Human Growth Hormone (4IU per day). Effects of Drostanolone / Masteron (desirable) There are principally two desirable effects of Testosterone: physical / athletic performance enhancement (endurance, strength, faster regeneration)physique enhancement (muscle buildup, fat loss)The rest of desirable testosterone effects that an individual might experience during the steroid cycle, include:increase in collagen synthesis and bone mineral content. Collagen is the protein-based construction material for connective tissues throughout the body (the ligaments, tendons, cartilage, joints, and bones).heightened self esteemdeeper (manly) voicedarkening and thickening of body hairincrease in levels of IGF-1 and MGF hormones (which also promote muscle growth)increased hemoglobin (red blood cell count)anti-catabolic effect on muscle tissues by way of acting as an anti-glucocorticoidSide effects of Testosterone Propionate (and how to counter them) Internet / forum rumors It is rumored that Propionate is better for cutting and fat loss phases, and it supposedly causes less water retention than other esterified types of Testosterone. This is simply nonsense that has been passed on by people developing improper conclusions not based on scientific reasoning. Propionater (like any other ester bonded to Testosterone) is always broken off by enzymes in the body, after which 100% pure bio-identical Testosterone is left as a result. This Testosterone is then free to do its job in the body. The same occurs with any and all esterified forms of Testosterone. Therefore, the only possible difference that esterification causes to Testosterone effects is its half-life and rate of release. The esters only determine how much Testosterone is released into the bloodstream per given time frame. Underground labs and their brand names There are countless of underground producers of Testosterone Propionate. Some are proper labs who follow good manufacturing practices and have adequate equipment operated by knowledgable staff. Majority however are just "bathtub pharmacies" created in someone's back room. They order raw materials from Asia, mix it together and repackage into vials - the end user can only hope it was done in sterile environment. There are too many underground brands to list and new one are created more or less daily. Some of the names are: History of Masteron / Dronstanolone Masteron (Drostanolone) was first invented in 1959 by Syntex. About 10 years later it was released on the American market by Lilly as brand name Drolban. Syntex marketed it internationally instead. Masteron was first approved in USA for the use as treatment of female breast cancer. In the 1970s and 1980s it became very popular in the bodybuilding community. As more effective cancer treatments were discovered Dronstanolone was slowly phased out for that purpose. Pharmaceutical manufacturers began to slowly discontinue sales. Drolban bramd was officially terminated in the late 1980s. Today Masteron remains on the list of approved medications, but it is not being manufactured or sold by the pharmaceutical giants. This makes it effectively bodybuilding only drug produced by underground labs. Post Steroid cycle treatment Masteron iteself does not aromatize into Estrogen and thus does not require anti-estrogen protection throughout the cycle. However it is most commonly used in combination with a testosterone (which does require protection) Following the end of any cycle, a thorough and proper Post Cycle Therapy (PCT) program is always necessary, where Testosterone-stimulating ancillary compounds such as Nolvadex and/or HCG should be utilized in order to facilitate the normalization of the HPTA and endogenous Testosterone production as quickly as possible. PCT protocols and programs are usually run for the duration of 4 to 6 weeks after all anabolic steroids have cleared from the body following the end of the cycle. Failure to engage in a proper PCT program can result in permanent damage to the HPTA, whereby the individual produces insufficient/deficient levels of Testosterone (a medical condition known as hypogonadism), and medical treatment in the form of TRT (Testosterone Replacement Therapy) for life will be required. ..
