Primobolan UK and side effects, positive effects in sports

The bodybuilders and athletes focus more on their muscle development, for this Primobolan can prove very helpful because it is the oral steroid, which allows competitor to improve their capabilities by improving the time that they generally spend to prepare for their competition. Primobolan is the legal anabolic steroid and key enhancer of several competitive sports. This steriod is the methenolone acetate and methenolone is the steroidal hormone, acetate means this steroid is linked to ester that allows any steroid to take it orally.

Methenolone or Primobolan is the DHT-derivative anabolic steroid released in the year 1962 in injectable and oral forms. But, both of the steriod versions were out of the United States shelves in a year. In year 1965, Schering, one of the manufacturers from Germany acquired its patent from Squibb and again re-launched this steroid in oral acetate under Primobolan name. From there the name of this drug is synonymous with.

Primobolan is an only oral steroid and is non-17caa and decreases any risk of the liver toxicity to an extent. However, tradeoff is this steroid has got very poor oral bioavailability and is weak compared to other anabolic steroids that are in the market. One of its injectable versions that come with longer and slow acting ester was renamed later on from Primobolan depot. It is hardly found in the UG labs nowadays. There are people who acquire raw powder type of the Primobolan known as the Primobolan Ace & use their personal recipes for the injectable use that can be quite risky.

Suppose you want to make use of Primobolan, stick to its oral version. Even though it is weaker compared to an injectable form, Methenolone use was discontinued quickly.  These days, this is used by the bodybuilders and atheletes to improve the physical performance as well as muscle mass. There’re 2 types of Primo. Now, let us have a close look at them in complete details.

About Methenolone Enanthate

Methenolone Enanthate is an injectable version. This has the longer-lasting ester compared to oral version and half-life of the compound is long, around ten days or so.  This derivative is derived from the Dihydrotestosterone that means this will not aromatize. It means the users will not need to worry at all about any kind of side effects like Gynecomastia.

Methenolone Acetate

Methenolone Acetate is an oral version of the Primobolan steriod. Like mentioned before, the compound has the shorter life than injectable primo and half-life of the compound will be around four to six hours. The Methenolone Acetate is an only steroid, which is non 17alpha-alkylated. And that makes it not very high liver toxic compared to other oral steroids like Winstrol and Dianabol. But, this has got the weak bioavailability and can be weaker compared to other steroids out there.

Cutting cycle of the steriod:

Most of the athletes want to add their Primobolan steriod to the cutting cycle due to the ability of promoting the fat loss as well as offer you effect of the muscle hardening. Also, this will prevent the muscle loss and, add very little small amount of the muscle when you are in it. Because of its weak muscle building, this is hardly added to the bulking cycle and to off-season cycle.


There’re some mixed reviews about the ability of Primobolan to improve libido. There are some users who claim they feel horny when they were in their teens. Some feel the mild improvement in their libido. Any ways, suppose you are making use of the steroids, which will dent the libido, even any mild increase will help in improving the feeling and mood of their wellbeing. Primobolan steriod is compared with the Masteron in the terms of libido boosting elements. This caveat is Mast will put the hair shedding on the nitrous for somebody highly prone to this steriod. Primo hardly causes any kind of hair loss.

Strength and Endurance:

There are some moderate increments in the strength all along with the quick recovery among men. The females experience high increases in their strength as well as speed when they are at Primo.

Fat loss and muscle hardening:

Primobolan will make the muscles look much harder as well as defined mainly delts and traps. This, many seasoned professionals will add this to the stack as pre-cycle steroid. It is where this comparison with the Tren stems from. Since Trenbolone will make the traps to pop out just like anything. But, vascularity one generally has from the Primo is not very close to Tren will offer you.

Effects of Primobolan

Primobolan is generally used during the cutting cycles and pre-contest and will help with the muscle hardening however, it is not actually very effective in mass building. While it comes about gaining the right size, the bodybuilders can select the compound like Anadrol and Deca Durabolin to build their size. Most of the people underestimate effects of the Primobolan and on own, it is not very powerful and you may compare this to Masteron.

However, when this is stacked with some other AAS and it is when this gets an ability of showing the complete potential. Obviously, it is not very strong as popular steroid Trenbolone and has got their personal effects. This is primarily called for the muscle hardening effects. This can actually make you to look fuller, defined and harder. You may expect higher vascularity, improved fat loss and strength. Primo can also highly speed up in your muscle recovery method.


Primo can suppress you over 50% when you are using this in the standalone cycle (and not suggested). Ideally, 50% of suppression doesn’t warrant the PCT protocol. However, since Primobolan is been clubbed with potent androgens, the PCT protocol can be essential since multiple steroids can totally shut you down that will cause the post-cycle depression while you come out off its compounds.

Dosages and Cycle

This is based on the anecdotal experiences, many bodybuilders appear to take around 400 mg of the injectable Primo every week. The Anecdotal experiences also tell us this cycle will be around 8 – 10 weeks. While it comes about oral primobolan, the normal dosage appears to be around 150mg daily. You will find the bodybuilders running it at the higher dosage; however this is not at all advised. Often it gets stacked with the steroids like Testosterone Enanthate or Sustanon.

Primobolan for the Women

As this is considered the mild compound, you will find that a lot of female bodybuilders also use this. An average women dosage appears to be around 25 to 50 mg per week for four to six weeks. Anavar and Primo are two highly popular compounds used for the women and they are a bit mild when compared to rest but carry a lot of side effects if used in a long run. Women must also watch out their virilization symptoms when they are on any steroids.

Side Effects of Primobolan

Although Primobolan depot may not be the most powerful of steroids, but it carries some of the side effects. It must make you to think twice when using the anabolic steroids. Even, I will suggest that you can check out the legal steroid alternatives that are available in the market. The side effects that are associated with Primobolan use will include the hair loss, testosterone suppression and acne. It means the Post Cycle therapy will be required to restore the levels of hormone.

What Are the Alternatives?

The steroids will have some very serious health effects and I recommend staying away from it. There’re some better options to such compounds. Even, I am the big fan of Crazy bulk legal steroids. And they can help you to reach the goals in the safe and natural way possible.

Primobolan History

At present, Primobolan can be produced just in Europe by the company named as Schering, the German pharmaceutical firm. Originally, methenolone steroidal was been identified for the development by some US pharmaceutical company, known as Squibb in the year 1962. Squibb made 2 versions of methenolone steroid in names of Nibal & Nibal Depot. And Nibal was quite similar to current Primobolan; it means this was planned for the oral administration. Nibal Depot, but, was the injectable type of steroid. And Squibb made Nibal in all forms for its medical use; however, they dropped the Nibal for profitable pharmaceuticals. While Schering bought rights to the methenolone, and they identified the market for steroid. Schering, just like Squibb, also produced injectable and oral versions of Primo. And in the year 1993, Schering finally discontinued its production of their injectable version of Primo, and realizing there was higher profit for focusing the marketing as well as production completely on the Primobolan as the methenolone acetate.

Looking at the Benefits

Since with anything that we put in our system, we need to know benefits that will supply to our body, particularly when we spent hours in gym daily. So, to understand benefits from the Primobolan, fast examination of this helps outside the gym is essential:

  • People suffering from any wasting diseases.

With that in mind, it’s understandable why a lot of athletes generally prefer Primobolan. The Primobolan maximizes the protein synthesis; it means the athlete gets most out of this food putting in the bodies. Besides this, Primobolan generally helps in building the lean muscle mass. Somebody who is using the Primobolan steriod will not ‘bulk up’ on it and they can get a bit stronger. Since lean muscle gets developed, Primo increases the fat loss. Lastly, Primobolan increases immune system and this allows user to be healthier longer that means a little more time to get very strong.

Side effects of Primobolan

Each pharmaceutical has got some of the possible side effects, so Primobolan is not at all different than others in such respect.

Production of Testosterone

All the anabolic steroids generally act as the testosterone suppressors. That depends upon dosage as well as period of time Primobolan gets used can have the direct effect over athlete’s testosterone production. Whereas both female and male athletes will make use of the Primobolan at higher effect, just male athletes must think of taking this needed estrogen supplements just to make sure that they do not suffer any kind of prolonged period before the testosterone returns at the normal levels after the Primobolan use.

Effects of Androgenic

The side-effect generally applies to women and men who make use of Primobolan steriod, though effects differ from one person to another person, which depends on an individual physiology as well as body’s tendency to some traits. Among men, people who tend on acne will suffer some acne outbreaks that will range from the mild to severe. So, any male that has the maternal history of the male-pattern baldness may expect higher hair loss. Men and women will expect experiencing the higher body hair growth, also women, are known to suffer at clitoral enlargement and deepening of the voice.

Psychological Effects

As the anabolic steroid alters the atheletes physical makeup, there are some naturally happening psychological effects. Higher and lesser amounts of the chemical will drastically change the individual, and the risk will be there when the additional steroids get introduced. The careful Primobolan administration will help any athlete to recognize any kind of unwanted psychological changes, so adjust the anabolic regimen as essential. There are some side-effects of higher steroid intake that will include:

  • Irritability
  • Mood swings
  • Neurotoxicity
  • Cognitive impairment
  • Aggression
  • Violent behavior
  • Withdrawal (stopping this steroid immediately)
  • Dependence (on anabolic steroid)
  • Mania or Hypomania
  • Recklessness or Impulsivity
  • Delusions
  • Psychosis
  • Depression
  • Euphoria
  • Dysphoria
  • Anxiety
  • Suicidality

Whereas a person might not at all suffer from such common effects of the anabolic steroid usage, particularly as Primobolan is the mild steroid, possibility of the effects should be always kept in your mind.

Primo Dosage

The dosage for women and men will vary, and certainly it is not same for both the sexes. This is suggested that the men take this steriod for the maximum 8 weeks at one time. During such period, manufacturer recommended dose for the medicinal purposes will range from 100 to 150 mg every day, and this is reported that athletes who are using Primobolan steriod for increasing thier performance have seen some very good results with this similar dosage. Besides men, even women will be advised taking the Primobolan depot for the maximum of 4 to 6 weeks, with six being cut-off point. Unluckily, Schering doesn’t specify on how much of Primobolan that woman must take; however, female athletes using this steroid report best results with 25 to 50 mg doses daily.


Primobolan is not very effective and popular as steroids like Turinabol but has the place. Many bodybuilders select to stack this with some other anabolics for optimizing the effects and results.
