History and Overview of Rus Bio Drostanalone Enanthate (Masterone)
Masteron is a fairly old anabolic steroid first created in 1959 by Syntex and has been sold under several other brand names such as Masteril, Drolban and Metormon with Masteron remaining the most recognizable.
During the 1970’s and 80’s Masteron enjoyed significant therapeutic success, particularly in the treatment of inoperable breast cancer. Despite its success in cancer treatment and other areas of medicine, in the late 1980’s and early 1990’s Masteron began to disappear from the U.S. and European markets. Drostanolone is still an FDA approved anabolic steroid, but no U.S. pharmacy manufactures it.
During the 1970’s and heavily in the 1980’s Masteron become very popular among competitive bodybuilders. In fact, it has come to be viewed as an essential for contest prep for many bodybuilders and is a common favorite among recreational bodybuilders during their cutting cycles. Due to the Propionate ester that is attached Masteron must be injected at minimum three times per week with an every other day schedule being the most efficient. Because of the need for frequent injections and high demand for the steroid, many underground labs began manufacturing the Drostanolone hormone with the Enanthate ester attached. The new combination become very prominent in the early 2000’s and as such Masteron Enanthate was born. Rus Bio Drostanalone Propionate (Masteron) is the same anabolic steroid as Masteron Propionate; the hormone itself has not been changed. The only difference in the two compounds is the attached ester, which affects the drug’s active life and release into the body.
Rus Bio Drostanalone Propionate (Masteron) is a dihydrotestosterone (DHT) based anabolic steroid. Drostanolone is simply the DHT hormone structurally altered. The alteration exists through the addition of a methyl group at carbon position 2. This ensures the hormone doesn’t suffer metabolic breakdown brought on by the 3-hydroxysteroid dehydrogenase enzyme found in the skeletal muscle. This simple structural change also makes the hormone far more anabolic, and that gives us Drostanolone. Once the hormone has been created, altered from DHT, an ester is then attached, and in this case the ester attached is Enanthate. Enanthate is not a steroid or a drug but nothing more than a timing tool used for a drug.
As with Masteron Propionate, Masteron Enanthate is well known for being one of the only anabolic steroids that carries strong anti-estrogenic properties. This anabolic steroid cannot increase estrogen levels; in fact, it can actually decrease estrogen levels in the body. It is for this reason Drostanolone was successful in breast cancer treatment with the combination of Drostanolone and Tamoxifen being very commonplace for many years. Bodybuilders welcome this trait due to estrogen often being difficult to control with many steroids and lower estrogen levels often leading to a harder and more defined look during the cutting phase.
Side Effects of Rus Bio Drostanalone Enanthate (Masterone)
In many ways, Rus Bio Drostanalone Enanthate (Masterone) is a fairly side effect friendly anabolic steroid. Side effects of Rus Bio Drostanalone Enanthate (Masterone) use most certainly exist, but most men will find this steroid highly tolerable. As for females, virilization symptoms can be strong with this steroid, but we will also find they can be managed with the right plan. In order to understand the side effects of Rus Bio Drostanalone Enanthate (Masterone), we have broken them down into their separate categories along with all you need to know.
Rus Bio Drostanalone Enanthate (Masterone) does not aromatize and it does not carry any progestin nature making estrogenic side effects impossible with this steroid. This means gynecomastia and water retention will not be concerns. It also means high blood pressure that is sometimes caused by excess water retention will not be a concern. An anti-estrogen is not needed due to this steroid’s use; as discussed it can have anti-estrogenic effects itself. However, depending on the specific cycle/stack that’s implemented, an anti-estrogen may be needed.
The side effects of Rus Bio Drostanalone Enanthate (Masterone) can include those of an androgenic nature. Androgenic side effects can include acne, accelerated hair loss in those predisposed to male pattern baldness and body hair growth. Thankfully this hormone carries a moderate level of total androgenic activity despite being a direct derivative of the potent androgen DHT. However, individual sensitivity will play a strong role, this steroid is well-known for greatly enhancing male pattern baldness in sensitive men far more than many anabolic steroids.
An important note; the Drostanolone hormone is not metabolized by the 5-alpha reductase enzyme. This is the enzyme responsible for reducing testosterone to dihydrotestosterone. In the case of Rus Bio Drostanalone Enanthate (Masterone), it’s already DHT; there is no reduction. As there is no reduction, there is no metabolism and nothing to inhibit. This means the androgenic nature of Masteron will not be strongly affected by a 5-alpha reductase inhibitor such as Finasteride.
Due to its androgenic nature, Rus Bio Drostanalone Enanthate (Masterone) can produce virilization symptoms in women. Virilization symptoms can include body hair growth, a deepening of the vocal chords and clitoral enlargement. Virilization symptoms have been well-noted in breast cancer treatment plans, but this is normally due to the necessary high doses used to treat such a condition. In a performance capacity, it should be possible to use this steroid without related symptoms with a low dose. However, while individual response will dictate quite a bit, this will not be a primary recommended steroid for female athletes. If it is used and related symptoms begin to show, discontinue use immediately and they will fade away. If the symptoms are ignored, it is very possible they may set in and become irreversible.
