Introduction to Primobolan Enanthate:

The English name of Primobolan enanthate is Methenolone enanthate, which is an injection of Primobolan, also known as Primobolan Depot. The same ingredient in Primobolan (primobolan acetate by mouth), Primobolan Depot uses enanthate to slow the release of the steroid from the injection site. Primobolan enanthate provides a similar steroid release pattern to testosterone enanthate, with blood hormone levels remaining significantly elevated for approximately 2 weeks. Primobolone itself is a moderate-strength anabolic steroid with very low androgenic properties. Its anabolic effects are considered to be slightly lower than that of Deca. Many athletes use Primobolan a lot in preparation for fat loss, and Primobolan brings more muscle mass gain than muscle mass gain.

Primobolan Enanthate History:

Primobolan was first developed in 1960, and Primobolan enanthate was launched by Squibb in 1962. It was sold to the U.S. prescription drug market under the brand name of Nibal® Depot in the United States for a short period of time. In the same year, the rights to the drug passed to Schering in West Germany (now Bayer), and Nibal® Depot soon disappeared from the US market. Schering will market Primobolan under its newest and best-known brand, Primobolan® Depot. During the 1960s and 1970s, Primobolan was sold primarily in Europe, including countries such as Switzerland, Italy, Germany, Austria, Belgium, France, Portugal, and Greece. Until the late 1970s, Schering maintained patent control over Primobolan. Schering strictly protects its intellectual property from any potential infringement until its patent expires, even though the company has not marketed Primobolan in the U.S. market. While the U.S. has been unable to make commercial sales in the U.S. for decades, it has technically retained its status as an FDA-approved drug.

Primobolone is often prescribed as a pure muscle-building agent among anabolic drugs, and is commonly used in cases of post-surgery, persistent infection, wasting disease, and convalescent wasting. Primobolone is also used by some clinicians to treat osteoporosis, sarcopenia (the natural loss of muscle mass with age), some cases of chronic hepatitis and breast cancer (often as a secondary drug after other treatments) . Primobolone has also been used to promote weight gain in underweight premature infants and children in clinical studies, and it did so effectively with no signs of toxicity or adverse effects. In bodybuilding, athletes have long favored the drug's strong anabolic, weakly androgenic, and non-estrogenic properties, which make it ideal for building lean muscle without side effects.

Despite Primobolan's proven track record of clinical safety, by the 1990s Schering had grown into a multinational pharmaceutical giant and inevitably had to re-examine its global presence due to public concerns over sports doping Steroid products. Primobolone will be voluntarily withdrawn from most countries where it was originally sold. Today, the brand is only sold in a handful of countries, including Spain, Turkey, Japan, Paraguay and Ecuador. Despite the limited supply, Bayer is still (almost) a unique primetolone producer in the global human medicines business. In recent years, however, Primobolan has appeared in a handful of other formulations, mostly from underground or export companies

Common Specifications of Primobolan Enanthate:

Most Primobolan is packaged in 1 mL ampoules or 10 mL vials, and most are 100 mg/ml. Ingredients and dosages for other brands may vary by country and manufacturer.

Structural features of Primobolan Enanthate:

Primobolan is a derivative of dihydrotestosterone. It contains an extra double bond between carbons 1 and 2, which helps stabilize the 3-keto group and increases the anabolic properties of the steroid, and an additional 1-methyl group, which gives the steroid some resistance Hepatic metabolism protection. Primobolan enanthate is attached to the 17-beta hydroxyl group using methylphenol and heptanoate. Esterified steroids are less polar than free steroids and are absorbed more slowly from the injection area. Once in the bloodstream, the ester is removed, yielding free (active) primenolone. Esterified steroids are designed to prolong the window of therapeutic effect after administration, and may be injected less frequently than free (unesterified) steroids.

Primobolan enanthate is used to obtain enanthate, and the drug release rate is roughly the same as that of testosterone enanthate. The picture shows the pharmacokinetic release of testosterone enanthate.

Methenolone Enanthate Side Effects (estrogen):

Primobolan is not aromatized by the body, 570 and has no measurable estrogen. Estrogen-related side effects should not be seen when this steroid is given. Sensitive individuals should not be concerned about developing gynecomastia, nor should they notice any noticeable water retention with this medication. The increase with methenolone should be mass muscle mass, not the smooth volume that usually accompanies steroid open aromatization. During a cycle, users should additionally not notice a strong increase in blood pressure, as this effect is also (usually) associated with estrogen and water retention. Methenolone is a steroid most favored during the cutting phase of training, when water and fat retention are major concerns and sheer quality is not the central goal.

Methenolone Enanthate Side Effects (androgens):

Primobolone, although classified as an anabolic steroid, may still have androgenic side effects. This can include oily skin, acne and body/facial hair growth. Anabolic/androgenic steroids may also exacerbate male pattern baldness. Women are warned that the use of anabolic/androgenic steroids can cause androgenic effects. These may include a deepened voice, irregular menstruation, changes in skin texture, facial hair growth, and an enlarged clitoris. Primobolone, however, is still a very mild steroid, and strong androgenic side effects are often associated with higher doses. Women often find this preparation an acceptable option and see it as a very comfortable and effective anabolic.

Methenolone Enanthate Side Effects (Hepatotoxicity):

Primobolan is not considered a hepatotoxic steroid; hepatotoxicity is unlikely. The study failed to produce significant changes in markers of liver stress when the drug was administered at therapeutic levels.

Primobolan side effects (cardiovascular):

Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to lower HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift HDL toward LDL balance in favor of a greater risk of arteriosclerosis. The relative effects of anabolic/androgenic steroids on serum lipids depend on dose, route of administration (oral vs. injection), steroid type (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Due to its non-aromatizable nature, Primobolone should have a stronger negative effect on cholesterol than testosterone or daika, but much less than c-17α alkylated steroids. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, to help reduce cardiovascular strain, it is recommended to maintain an active cardiovascular health plan and minimize saturated fat, cholesterol and simple during steroid use carbohydrate intake. Supplementation with fish oil (4 grams per day) and natural cholesterol/antioxidant products is also recommended

Primobolan side effects (testosterone suppression):

All anabolic/androgenic steroids are expected to suppress endogenous testosterone production when taken in doses sufficient to promote muscle gain. Without the intervention of stimulating substances such as testosterone, the body's normal testosterone levels should return to normal within 1-4 months after drug separation. Note that chronic hypogonadotropic hypogonadism may be secondary to steroid abuse and require medical intervention. At moderate doses of 100-200 mg per week Primobolone Enanthate is less inhibitory to the body itself than equivalent doses of Deca or Testosterone due to its non-aromatizable nature . If it is used for less than eight weeks, the body does not need to recover for too long (within 8 weeks).

Primobolan Enanthate Dosage

Prescribing guidelines for methenolone enanthate recommend a maximum dose of 200 mg at the start of treatment and a continuous weekly dose of 100 mg. Extended dosing regimens typically call for 100 mg every 1-2 weeks, or 200 mg every 2-3 weeks. The usual dosing regimen for male athletes calls for weekly doses of 200-400 mg for 6 to 12 weeks, which is sufficient to promote a very significant increase in lean muscle tissue. However, current doses of the drug used by bodybuilders are as high as 600 mg or more per week, although such amounts may accentuate more of the androgenic effects of methenolone enanthate, but exacerbate its negative effects on blood lipids . Metenol enanthate is often used in a stack with other (usually stronger) steroids for faster and stronger effects. In the preparation stage of athletes, non-aromatized androgens such as fluoxymesterone and trenbolone are usually combined. The strong androgenic component here should help bring extra density and stiffness to the muscles. On the other hand, one might add another mild anabolic steroid, such as stanozolol. The result of this combination should again be a significant increase in muscle mass and stiffness, which should still not be accompanied by greatly increased side effects. Testosterone and Boldenone are usually used in conjunction with testosterone in a muscle building cycle.
