How to do Primobolan UK cycles: All information about Methenolone

Anabolic steroids are the man-made variations of the male sex hormone testosterone. Steroids are dangerous but no one can deny the fact that they will always be used by bodybuilders to some degree. Not all steroids are the same. Some are more powerful than others, while some are average. Consumption of some of the steroids will transform you into monsters while others help burn body fat and can make you ripped and shredded.

There are certain advantages of primobolan. It helps build muscles and burn fat, helps improve the athletic performance and has some health benefits as well. Here in this article we will be discussing about what is a Primobolan cycle, what are its implications, how it works, the side effects, cycle information and dosage.

What is Primobolan?

Primobolan (or Primo) is a comparatively weak steroid with many benefits. When used in correct amount, it doesn’t cause any harm to the body. Primobolan is readily available and is less risky compared to other steroids. The effectiveness of any drug depends on what the user wants from the steroid. Say if you want to build your body muscles like a mass-monster, then primobolan alone will do no good to you.

However, if you wish to shred off and still add some size, definition and vascularity to your body, then Primo could be the best option. It is particularly beneficial for people who are sensitive to estrogenic side effects because of androgenic activity.

Metenolone enanthate or methenolone enanthate is sold under the brand name Primobolan. It was created in 60s in Germany and comes in oral and injectable form. Initially it was used as a medicine for underweight children and as a treatment for conditions like osteoporosis and muscle-wasting conditions. The drug popularized when it was rumored to be Arnold Schwarzenegger’s steroid of choice while cutting.

Primobolan (Methenolone Acetate) is a very popular steroid used by athletes to add lean body weight, increase their muscle mass, prevent muscle wastage and improve the strength output. Primo is usually available as an oral steroid. The injectable form is known as Primobolan depot.

Primo is a relatively safer drug and is considered to be a low-level androgen. It is mostly used as part of therapeutic treatment plans for individuals with degenerative muscle conditions. Primobolan is the only oral steroid that doesn’t cause hepatic toxicity.

Athletes prefer Primo over other steroids to improve their performance and strength. Primo is a favorite to bodybuilders and cardiovascular oriented athletes. It is free of side effects, smooth and consistent. And thanks to this popularity of the drug, the oral versions of Primo have become one of the most counterfeited steroids in the market. So be cautious before buying!

Advantage of Primo

Primobolan is very effective drug for any cutting cycle. It’s effective at building moderate amounts of muscle mass. During a cut it will save or even give gains you otherwise couldn’t have dreamed of getting.

Primobolan is non-estrogenic so it’ll never cause things like gynecomastia or water retention of which the bodybuilders and strength athletes are at greatest risk. It doesn’t have much effect on the blood pressure which makes it an ideal addition to any cutting steroid stack.

Downside of Primo

Primo is a very mild steroid in terms of gains. There are many steroids for gaining gigantic levels of strength and muscle mass from your cycle like trenbolone but for a safe and smooth addition to the testosterone cycle, primobolan is the best option. You should follow a proper PCT protocol after your cycle.

Primobolan is known to cause cholesterol issues also. However, safe cholesterol levels can be maintained while using Primo. Maintain a good cardiovascular health and supplement yourself with omega fatty acids. The steroid is slightly high-cost because of its effectiveness, safety and popularity. 

Side Effects of Primo

The general side effects similar to that of using other steroids such as in men: hair loss, acne, erectile dysfunction, etc. and in women: body hair growth, deepening of the vocal cords and clitoral enlargement in women are seen. PCT protocol is necessary because it suppresses the natural production of testosterone.


We know that primo is a weak steroid containing enanthate ester so anything less than 400mg per week is completely a pointless use of Primo. Other anabolic steroids when used in higher doses have many side-effects but with Primo there’s no such risk.

When Primo is stacked with testosterone, 400-800mg per week is an effective dose (Higher doses are the most effective). Primo has two main effects in such a stack-1) amplifies the effects of test, so 500mg of test enanthate seem like 750mg or more and 2) you can have quality muscles even with your diet being off from time to time. But with a spot-on diet, Primo and test will be the most effective. If you wish to use Primo on its own or without test, use a minimum of 600-800mg per week. If you can afford then 1000mg per week of Primo will highly reward the user.

People often ask regarding use of Primo with Trenbolone. Without test you are likely to be shut down and need some sex medicines as well as HCG. If you want a test-less cycle, Primo and Tren can prove to be a great cutting cycle. A very good cutting cycle that is test-free would be Primo (600-1000mg per week) with Anavar (60-80mg per day).

Because of the enanthate ester attached to the Methenolone base in Primo, it should not be run for less than 8 weeks. High Primo dose is useful for those using higher doses of test and experiencing loss of appetite from this. Primo doesn’t cause appetite loss as such. Thus while bulking this, can give a chance for the diet to be spot-on.

Primo suppress and shut you down but it is roughly about half as suppressive as test. Therefore, a 12 week Primo cycle would shut you down similar to a 6 week test cycle. That’s why Primo alone can be run up to 20 weeks without fear of a very difficult recovery in post cycle therapy (PCT). Run PCT for approximately 14-18days after the last Primo injection.

Some example Primo cycles

1) Test-free cycles

  • Primo 600-800mg pw weeks 1-12; Anavar 60mg ed weeks 1-8
  • Primo 600-800mg pw weeks 1-12; Tren Ace 75mg eod weeks 1-6
  • Primo 800mg pw weeks 1-12; Masteron 400-600mg pw weeks 1-14
  • Primo 1000mg per week up to 20 weeks (expensive)

2) Primo cycles with Test

  • Primo 600mg pw weeks 1-12; Test enanthate 500mg pw weeks 1-12
  • Primo 600mg pw weeks 1-12; Test prop 100mg eod weeks 1-14; Tren enanthate 300-400mg pw weeks 1-10 (Superb cutting cycle for advanced user)

There are many other different cycles which can be done with primo. Generally, the amount of Primo to be used in the cycle depends on how much you can afford and how many injections you have to do. With Primo it is better if you do more. The minimum amount should be not less than 400mg/week.

Primobolan Depot

Primobolan Depot enhances the immune system which is very beneficial to those who use steroids every day. During a cutting cycle, calories are restricted so the body becomes weak and fatigued from intense training. The immune system also becomes weak. At this time Primobolan can be used as a supplement to strengthen the immune system and fight off infections and common cold.

Primo can be very advantageous for females during the off-season. Women are more sensitive to steroids. Primobolan Depot may not be so effective for men during a bulking phase as it is for women. Women can pack on some off-season muscle mass due to the metabolic enhancement and fat burning properties of primo.

Injectables are considered to be more effective in case of steroids. When you take injectables, you need to take less amount of primo than in oral forms. The injectable form is more effective and easy to find.

For men: 8 week cycle between 100mg-150mg daily doses for orals or 400mg-700mg per week for injectable primobolan. The advanced users have reported doses up to 1000mg per week for injectables.

For women: 4-6 week cycle, doses are between 25mg-50mg per day for orals, or 50mg-100mg per week for injectables.

The half-life of primo in oral form is about 2 or 3 days so better to take your dose daily. Injectable primobolan has a higher half life of roughly 7 to 10 days so needs to be administered once per week (you can divide it into two smaller doses if you want). 

We know that primo is a relatively mild drug so men should not run Primo as their base during a cycle. Always run it alongside Testosterone. However, Primo is an effective base for Women’s cycles. Primo is good for a recomp or in a cutting cycle but not for bulking cycles.

Solo Cycles

Many people who use Primobolan Depot are not found in a solo cycle. If you run primo solely, you’ll have to use higher doses. For a desirable outcome, a Primobolan Depot solo cycle typically lasts for twelve weeks. The cycle has been outlined below:

Week Primobolan Depot
1 750mg per week
2 750mg per week
3 750mg per week
4 750mg per week
5 750-1,000mg per week

Benefits of Primobolan Cycle

Primobolan has a very effective rate of binding with the androgen receptor which leads to an increase in the rate of fat breakdown. So Primobolan helps to lower the fat content of the body. When the fat percentage is lowered, the muscles are clearly defined and vascularization is improved. Primobolan is weak steroid when cycled on its own. So don’t over expect that you’ll look stage-ready at the end of the cycle.

You do not lose the muscle mass with the use of Primobolan Depot. It helps in maintaining the muscle mass gained during heavy weight training. You will feel an increase in energy depending on the dosage taken during your solo cycle. But you’ll need to eat clean, train consistently and allow your body to take adequate rest.

Take solo cycle of primobolan depot only if you’re looking for small muscle increases. In case of females, they can run solo cycle on their own. It will do wonders in promoting a small amount of muscle/size increase in the body.

Primo helps you to shed fat, retain muscle, increase athletic ability and look clean and defined. However, results are not similar for every person. It depends on various factors like your age, body type, level of training, length of cycle, dose of Primobolan taken and whether you added testosterone as the base to your cycle or not.

Cost of buying Primobolan

Primo is a popular drug we know but it is not easily found. The pharmaceutical grade of the drug can’t be readily sourced in the US. But it is possible to buy online from other countries. Primobolan acetate is almost impossible to find, even from under-ground sources. That’s why buying primo often means purchasing it in enanthate form.

Though popular, primo is a quite costly drug. It cost typically starts from $15-20 for a single 1ml vial of 100mg strength.

Sports that use Primo

The bodybuilding community uses Primobolan. It has also found popularity within other sports. Primo is free of side effects and steadily builds strength without bulk. It has become a very popular performance-enhancing drug. There are number of different sports which have reported illegal use of the drug from competitors. This includes the high profile case of Major League Baseball star Alex Rodriguez.

Legality of Purchase and Usage of Primo in the US

In US all kinds of anabolic steroids are classified as a Schedule III controlled substance i.e. you can use them only with a prescription from a physician for therapeutic use. According to the US law, the supply, shipping or even possession of primo is an offense and could be punishable by both a heavy fine and a jail sentence.

Other countries round the globe such as the UK and Canada are more lenient towards possession of anabolic steroids for personal use. In many nations primo can be bought openly. If you have purchased primo somewhere else legally and you want to bring it to US, you can’t do that.


Primo we saw is a safe drug and suitable for both men and women. The oral form is less likely to be found and is easily counterfeited so mostly injectable forms (primo depot) are used. We advise that before going for any steroid cycle train, pen down your goals and be serious about your diet and training.
