 History of Primobolan

The history of Primobolan dates back to the 1960s when the formula for the drug was first developed.In 1962,Squibb,a pharmaceutical company,began producing the practical versions of Primobolan for the American market.The initial formulations were known as “Nibal depot,” which was methenolone enanthate for injectable use,and “Nibal,” an oral acetate formulation.

However,Schering,another pharmaceutical company,quickly acquired the rights to the methenolone hormone,leading to the restriction of production runs for these drugs.Schering renamed the products as “Primobolan” for the oral form and “Primobolan Depot” for the injectable form,which are still commonly used names today.

Despite being exclusively promoted by Schering for its low risk-to-reward ratio and effectiveness in preserving lean tissue,Primobolan was eventually taken off the market in the United States.However,it is still FDA-approved for human use,and healthcare professionals can order it on a case-by-case basis for medicinal purposes.

Primobolan was originally used in the 1960s to treat muscle atrophy caused by various illnesses.It was particularly valued for its ability to reduce muscle degradation while having a low risk of androgenic and estrogenic side effects.This made it a suitable option for patients who were sensitive to highly androgenic or estrogenic substances,including women and children.

In the bodybuilding community,Primobolan gained popularity during the 1960s and continued to be widely used throughout the 1970s.While it is speculated that Primobolan may have been one of Arnold Schwarzenegger’s preferred steroids,there is no conclusive evidence to support this claim.Nevertheless,Primobolan,along with other anabolic steroids and growth hormones,was well-known and utilized within the bodybuilding culture.

Today,Primobolan remains recognized for its ability to preserve lean tissue and its low risk of adverse side effects.Although its availability in the United States is limited,Primobolan is still utilized for specific medical purposes where its benefits are highly regarded.

Understand what is Methenolone acetate powder?

Methenolone acetate powder refers to the powdered form of the steroid compound known as methenolone acetate.Methenolone acetate is an oral anabolic androgenic steroid (AAS) derived from dihydrotestosterone (DHT).It is commonly sold under the brand name Primobolan.

Methenolone acetate powder is the raw,unprocessed form of the compound,typically used by pharmaceutical companies,compounding pharmacies,or underground laboratories for the production of oral tablets or capsules.It is also sometimes used by individuals who prefer to create their own formulations or who engage in the illicit production of steroids.

The powder form allows for greater flexibility in dosage and administration compared to pre-made tablets or capsules.However,it is important to buy methenolone acetate powder from a reliable supplier.It is crucial to use pure methenolone acetate powder to avoid unnecessary side effects.

 How does the steroid Primobolan work inside the human body

The steroid methenolone acetate,commonly known as Primo or Primobolan,works inside the human body through various mechanisms to promote its desired effects.Here’s how Primo functions:

Androgen Receptor Activation: Methenolone acetate binds to androgen receptors in cells throughout the body.This interaction initiates a cascade of events that leads to an increased synthesis of proteins.By activating the androgen receptors,Primo enhances protein production,contributing to muscle growth and repair.

Nitrogen Retention: Primo has a positive impact on nitrogen balance in the body.It promotes nitrogen retention,which is essential for maintaining an anabolic (muscle-building) state.By preserving nitrogen levels,Primo supports protein synthesis and prevents muscle breakdown,resulting in improved muscle mass and strength.

Enhanced Protein Synthesis: Methenolone acetate stimulates protein synthesis,the process by which cells build proteins from amino acids.Increased protein synthesis helps repair damaged muscle tissues and aids in the growth and development of lean muscle mass.This contributes to improvements in muscle size,strength,and overall athletic performance.

Increased Red Blood Cell Production: Primo has the potential to stimulate the production of red blood cells (erythropoiesis).This can enhance oxygen-carrying capacity,leading to improved endurance and stamina during physical activities.

Fat Metabolism: While Primo is not primarily known for its fat-burning properties,it may have a mild impact on fat metabolism.It can help reduce fat deposition and promote a leaner physique,especially when used in calorie-restricted diets or during cutting phases.

It’s important to note that the specific mechanisms of Primo’s action may vary depending on the individual and their genetic factors,dosage,duration of use,and overall lifestyle factors.Additionally,Primo’s effects are typically milder compared to other more potent anabolic steroids,which can be advantageous for those seeking a less aggressive approach to muscle growth and performance enhancement.

Primobolan Benefits for Bodybuilding

Methenolone acetate(Primobolan) offers several potential benefits when used responsibly.Here are some of the key benefits associated with methenolone acetate:

  ①Increasing Lean Muscle Mass 

Methenolone acetate promotes the development of lean muscle mass.It enhances protein synthesis,leading to increased muscle growth and strength.Users often report gradual,quality gains in muscle size without excessive water retention.

  ②Preserving Muscle Tissue 

Methenolone acetate has the ability to preserve muscle tissue during calorie-restricted periods or cutting cycles.It helps prevent muscle breakdown while promoting fat loss,allowing individuals to achieve a leaner physique while maintaining their hard-earned muscle mass.

  ③Enhancing Performance and Endurance 

Methenolone acetate can improve athletic performance and endurance.By increasing red blood cell production,it enhances oxygen-carrying capacity,leading to improved stamina and reduced fatigue during physical activities.

  ④Improving Recovery  

Methenolone acetate aids in recovery from intense workouts or training sessions.It promotes the repair of muscle fibers,reduces muscle damage,and speeds up recovery time between workouts,allowing individuals to train more frequently and with higher intensity.

  ⑤Reducing Estrogenic Effects  

Methenolone acetate has a low propensity for estrogenic side effects,such as water retention and gynecomastia (breast tissue enlargement).This makes it a favorable choice for individuals who are sensitive to estrogen-related issues.

  ⑥Mild Androgenic Effects  

Methenolone acetate is known for its relatively mild androgenic properties.It carries a lower risk of androgenic side effects,such as hair loss,acne,and virilization in women,compared to more potent steroids.This makes it a popular option for those seeking anabolic effects with a lower risk of unwanted androgenic effects.

  ⑦Reducing Liver Toxicity 

Methenolone acetate is less hepatotoxic (toxic to the liver) compared to some other oral steroids.While it is still essential to exercise caution and monitor liver function when using any oral steroid,methenolone acetate is generally considered to have a lower risk of liver toxicity.

It’s important to note that individual experiences may vary if you use low quality of oral primobolan.There are many Methenolone acetate powder for sale online and It is easy to buy Methenolone acetate powder.But to get high quality primobolan acetate powder,you need throw your efforts to find the reliable supplier.AASRAW is one of the regular manufacturers supplies methenolone acetate raw powder.

Is primobolan for cutting or bulking?

Primobolan (Methenolone acetate powder) is generally considered more suitable for cutting rather than bulking cycles.It is an anabolic steroid with relatively mild anabolic properties,which means it is not as potent for muscle growth as some other steroids.However,it does offer several benefits that make it popular for cutting phases.

Primobolan is known for its ability to preserve lean muscle mass while promoting fat loss.It has a reputation for aiding in the development of a harder and more defined physique.Additionally,Primobolan has a low tendency to cause water retention or aromatization (conversion to estrogen),which can contribute to a leaner appearance.

Although Primobolan can be used during bulking cycles to support quality muscle gains,it is generally not as effective for this purpose compared to other anabolic steroids.It is commonly used by athletes,bodybuilders,and fitness enthusiasts during cutting cycles to help maintain muscle mass while reducing body fat.The experienced buyer will often purchase methenolone aceate powder wholesale for better price.

  what is the cycle of Methenolone acetate(Oral Primobolan)?

Methenolone acetate,also known as Oral Primobolan,has a shorter half-life compared to the injectable form (Primobolan Depot) and requires more frequent dosing.Here is an example of a typical cycle for methenolone acetate:

Cycle Length: A Primobolan acetate cycle typically lasts 6 to 8 weeks.

Dosage: The recommended dosage for men is typically in the range of 50-100 milligrams (mg) per day.Some individuals may increase the dosage up to 150 mg per day,but higher doses may increase the risk of side effects.

Frequency: Primobolan acetate is usually taken daily due to its short half-life.Splitting the daily dosage into two equal doses,one in the morning and one in the evening,is a common practice.

Stacking: Primobolan acetate powder is often used in combination with other anabolic steroids to enhance its effects.For cutting cycles,it may be stacked with compounds like Winstrol or Anavar.When used in bulking cycles,it can be combined with stronger androgenic compounds like testosterone.

Post Cycle Therapy (PCT): After completing a Primobolan acetate cycle,it is recommended to follow a post cycle therapy regimen.PCT helps to restore the body’s natural hormone production and minimize the potential side effects of steroid use.

Primobolan For Women

Primo is considered the best choice for women due to its low androgenic qualities and consequent lean gains.  Women tend to want to avoid excessive bulkiness and the smoothness that comes from water retention.  Also, since estrogen creates a “soft” look, steroids that aromatize can destroy the aesthetic they’re attempting to achieve. One drug which creates hardness without bloating or estrogen buildup is Masteron, but Masteron is a pure androgen. This can lead to the masculinizing side effects most women seek to avoid —  hair loss, body hair growth,  tougher skin, a deeper voice and most disturbing, enlargement of the clitoris.  Since Primo is almost purely anabolic, these sides are kept to an absolute minimum if dosages are kept reasonable. Women usually respond very well to a dosage of 50-100mg per week, although many opt for the oral version who feel it’s better at burning fat, though this is pure speculation and anecdotal. There’s no evidence to suggest as much, but empirical evidence is not without some merit.

Methenolone acetate Cycle for Females

Methenolone acetate is considered one of the more female-friendly anabolic steroids due to its mild androgenic nature.However,it is still important to approach its use with caution and follow proper guidelines.Here is some information regarding Methenolone acetate powder for women:

Dosage: The recommended dosage of Methenolone acetate powder for women is typically in the range of 10-25 milligrams (mg) per day.Starting with a lower dosage and gradually increasing it can help assess individual tolerance and minimize the risk of side effects.

Cycle Length: A Methenolone acetate powder cycle for women is usually around 4-6 weeks in duration.Keeping the cycle relatively short can help mitigate the potential for side effects.

Monitoring: Regular monitoring of side effects is crucial during the cycle.If any signs of virilization or other adverse effects occur,the cycle should be discontinued immediately.Pay attention to any changes in voice,increased body or facial hair growth,acne,or clitoral enlargement,as these can be signs of virilization.

Stacking: Due to its mild nature,Methenolone acetate is often used as a standalone steroid for female users.Stacking it with other strong androgenic compounds is generally not recommended to minimize the risk of virilization.

PCT: Post cycle therapy (PCT) is typically not required for women using Methenolone acetate powder,as the dosage and cycle length are generally conservative.However,it is still a good practice to monitor hormone levels and overall health after the cycle.

Methenolone acetate side effects

Methenolone acetate (oral Primobolan) is known for its relatively mild androgenic properties,which can lead to a reduced risk of certain side effects compared to other more potent steroids.However,it’s important to note that the use of any anabolic steroid,including Methenolone acetate,carries potential risks.Here are some possible side effects associated with Methenolone acetate:

Androgenic Side Effects

While Methenolone acetate has a lower androgenic rating compared to some other steroids,it can still potentially cause androgenic side effects.These may include acne,oily skin,increased facial or body hair growth (hirsutism),and potentially male-pattern baldness in individuals with a genetic predisposition.


One of the most significant concerns for female users is the risk of virilization,which refers to the development of masculine characteristics.These may include deepening of the voice,clitoral enlargement,menstrual irregularities,and changes in body composition.The risk of virilization with Methenolone acetate is generally considered lower than with stronger androgenic compounds,but it can still occur,especially at higher dosages or prolonged use.

Cardiovascular Effects

Anabolic steroids,including Methenolone acetate,can have negative effects on cholesterol levels,potentially leading to an increase in LDL (bad) cholesterol and a decrease in HDL (good) cholesterol.This can contribute to an increased risk of cardiovascular complications,such as heart disease and hypertension.


Methenolone acetate is a C17-alpha alkylated compound,which means it has been modified to allow for oral ingestion.This modification can potentially result in liver stress or hepatotoxicity.However,compared to some other oral steroids,Methenolone acetate is generally considered to have a low hepatotoxicity risk.

Suppression of Natural Testosterone

Like other anabolic steroids,Methenolone acetate can suppress endogenous testosterone production.This can lead to temporary testosterone suppression,which may require post cycle therapy (PCT) to help restore natural hormone levels.

The use of anabolic steroids,including methenolone acetate,should always be approached with caution and under the guidance of a qualified healthcare professional.Buy high quality Methenolone acetate powder can help to avoid unnecessary side effects.Suppler AASRAW supplies pure Methenolone aceate powder in factory price.

What are the differences between Methenolone acetate and Methenolone enanthate ​

Methenolone acetate

Methenolone enanthate


Methenolone acetate is available in an oral form,typically in the form of tablets or capsules,and is taken by mouth.

Methenolone enanthate,on the other hand,is an injectable form of the steroid and is administered through intramuscular injections.


Methenolone acetate is attached to the acetate ester,which allows for its oral bioavailability and quicker absorption into the bloodstream.

Methenolone enanthate is attached to the enanthate ester,which slows down the release and extends its half-life,resulting in a longer-lasting effect.


Methenolone acetate has a shorter half-life compared to Methenolone enanthate.The half-life of Methenolone acetate is typically around 2-3 days,requiring more frequent dosing.

Methenolone enanthate has a longer half-life of approximately 5-7 days,allowing for less frequent injections.

Dosing Frequency

Due to the differences in half-life,Methenolone acetate is usually taken daily or every other day.

While Methenolone enanthate is administered less frequently,usually once or twice a week.

Availability and Legality

Methenolone acetate is more commonly found in the underground market.

Methenolone enanthate,being an injectable form,is less prevalent in the underground market but can be obtained through legitimate channels with a prescription in some countries.

  What steroid to stack with Methenolone acetate Powder

When considering stacking Methenolone acetate powder (oral Primobolan) with other steroids,it’s important to look for compounds that have synergy with Methenolone acetate.For example,some individuals stack it with other mild androgenic compounds like Anavar (Oxandrolone) or Winstrol (Stanozolol) to enhance the cutting effects.Choosing compounds that are compatible in terms of their mechanisms of action and potential side effects is crucial.Here are a few examples of steroids that can be stacked with Methenolone acetate:

Winstrol (Stanozolol): Winstrol is a popular choice for cutting cycles due to its ability to enhance vascularity and promote a lean,hard physique.Combining Methenolone acetate with Winstrol can amplify the cutting effects and help maintain muscle mass while reducing body fat.

Anavar (Oxandrolone): Anavar is another steroid commonly used during cutting cycles.It provides mild anabolic properties with minimal androgenic effects.Stacking Methenolone acetate with Anavar can help further enhance muscle preservation and promote a dry,toned appearance.

Testosterone: Adding a low to moderate dose of testosterone to the Methenolone acetate cycle can help counteract potential suppression of natural testosterone production and maintain overall well-being.Testosterone can also provide a solid anabolic foundation for the stack.

Trenbolone: Trenbolone is a powerful anabolic steroid known for its significant muscle-building and fat-burning effects.However,it is important to note that Trenbolone is a potent androgen,and its use should be approached with caution due to potential side effects.Combining it with Methenolone acetate may result in an enhanced anabolic environment.

Remember,the selection and dosages of steroids for stacking should be based on individual goals,experience level,and potential risks.Another things is crucial is to buy high quality steroid raw powder with reliable manufacturer.Supplier AASRAW supplies high quality Methenolone acetate powder.Buy wholesale Methenolone acetate powder will get good price.
