It is mainly used in the treatment of low Testosterone levels in men. Testosterone helps the body to develop and maintain male sexual characteristics, such as a deep voice and body hair. It also helps with the maintaining of muscle mass and the prevention of bone loss and is necessary for the natural sexual ability or desire of it. Testosterone may also be used in certain adolescent boys that are late in the development with puberty. In any case this medication must be used regularly to get the most benefit from it.

Although the body needs Testosterone, it is important to know that anytime you introduce the body to a substance, there is the possibility of side effects. With any hormone that involves Androgen receptors, there will be the risk of Estrogenic effects. This can affect cholesterol levels, cause water retention or interfere with an individual’s personality and cause mood swings. As far as Androgenic effects from Testosterone Undecanoate, the user may experience; oily skin, acne, and male pattern baldness if already predisposed to such conditions. It is important to monitor blood pressure levels on a regular basis because the use of this steroid can have a negative impact on blood pressure levels because of water retention.

This steroid is said to be very versatile and has many uses and purposes when creating cycles and to treat low levels of natural Testosterone in the body. With regards to performance enhancement, Testosterone Undecanoate will enhance nitrogen retention as well as enhance the protein synthesis within the body. This is crucial for the purpose of muscle building in addition to cutting down on the recovery times after gruelling workouts. Testosterone Undecanoate also increases our IGF-1 production, increases our red blood cell count and decreases our level of Glucocorticoids. These benefits will provide us with a boost of energy and give us more endurance when working out.

For those suffering from low Testosterone levels, implementing with Testosterone Undecanoate can prevent erectile dysfunction, loss of libido, loss of muscle mass, loss of strength and help with our inability to lose bodyfat. Testosterone Undecanoate will help with mental clarity, irritability, depression, a weakened immune system and a declining memory (to name a few).

Testosterone Undecanoate Cycles for Bulking and Cutting

The recommended dose of Testosterone Undecanoate is 750 mg (3 ml) intramuscularly; followed by 750 mg (3 ml) intramuscularly after 4 weeks, then 750 mg (3 ml) intramuscularly every 10 weeks thereafter. Because the drugs half-life is extremely long it wouldn’t reach peak concentration levels in the body until nearing the end of a 16-week cycle. This is the reason for Testosterone Undecanoate not being used much in the world of sports. Testosterone Undecanoate’s main use is in Testosterone replacement therapy for males with low amounts of the hormone being produced naturally in their body. This steroid is not for cycling. Testosterone Undecanoate can be used when coming off a big cycle or for someone who has been running gear for years non-stop. It will be effective in the way of post cycle therapy to help an athlete’s body get back on track after stopping very long cycles.

Bodybuilders and athletes usually stack Testosterone Undecanoate injections with other Anabolic steroids such as Winstrol, Anavar or Nandrolone to maximum the effects of the cycle. Cycles with Testosterone Undecanoate may last longer than average cycles because of its slow acting nature. But adding Nebido to a cycle with the above listed steroids can be beneficial to most men since the steroid is well-tolerated.  However, despite carrying all the Testosterone traits, it will normally only be used in low Testosterone treatment plans. You will rarely find Testosterone Undecanoate being used in performance enhancing circles. For best results, use Testosterone Undecanoate with other steroids is recommended. For combination, the following drugs are commonly used:

  • Trenbolone;
  • Methandrostenolone;
  • Nandrolone;
  • Winstrol;

What is injectable Testosterone Undecanoate Cycle Lengths?

Injectable Testosterone Undecanoate is either ran year-round as maintenance or for TRT. As for the oral form of Testosterone Undecanoate, cycles should generally follow the same guidelines as cycles of any other Testosterone products, although it may have to be dosed higher, due to its poor bioavailability. Oral Testosterone Undecanoate can be used in a solo cycle or as a Testosterone base stacked with other steroids for a cycle. Cycle lengths for Testosterone Undecanoate range 8-16 weeks. As I said before, it is not a very popular Testosterone product for the purpose of performance or physique enhancement among bodybuilders and is rare to find information on cycles for this steroid.

To get the expected effects of Testosterone Undecanoate, the athlete or bodybuilder should use it in a cycle (taking into account the characteristics of the organism, it can be individual for each athlete). It is important that the selected combination does not have a negative impact on the body. It is important to carefully plan your program and know the dosages needed during the cycle.  Dosages and the duration of the cycle will depend on the goal of the individual. Cycles vary in length depending on personal preferences and goals. Also, the athletes or bodybuilders experience with Anabolic steroids will impact the length and dosages of the cycle that they’re planning to run.

For how long can Testosterone Undecanoate be detected?

Testosterone Undecanoate has a half-life of 33 days, allowing it to maintain serum levels in the normal range for over six weeks. Injectable Testosterone Undecanoate is primarily used in the treatment of low Testosterone due to extremely long half-life. Detection time for injectable Testosterone Undecanoate is 5 months.

Testosterone Undecanoate in the capsule form such as Jatenzo are much different. Concentrations peak about four hours after taking your dose. Because of this it is recommended that users take 40-80mg three times per day. Detection times for Testosterone Undecanoate in capsule form are around one week. Oral steroids no matter which one, clear from the body much faster than injectable.

Dosage and Administration Recommendations with Testosterone Undecanoate

Testosterone Undecanoate in injectable form comes containing 250 mg/ml of the steroid dissolved in oil and packaged in 4ml ampules containing 1,000mg of steroid in total. The recommended dose of Testosterone Undecanoate is 3 mL (750 mg) injected intramuscularly, followed by 3 mL (750 mg) injected after 4 weeks, then 3 mL (750 mg) injected every 10 weeks thereafter. With the use of Testosterone Undecanoate in oral form this process is much different. Medically, Testosterone Undecanoate dosages are prescribed in the range of 120-160mg per day for the first 2 to 3 weeks. After this period the dosage gets reduced to 40-80mg per day. For performance and physique enhancement, the oral dosage must understandably be far greater. A minimum of 250mg per day is required (6 or 7 capsules) to see any measurable effect, and many individuals claim that the results at this range are on the low end. Commonly, oral Testosterone Undecanoate is used at a dosage of 400 – 500 (10 – 14 capsules) per day. Advanced or experienced users may require even higher dosages than that.

If you use the drug in the form of injections, the natural question arises: How to inject Testosterone Undecanoate or other injectable steroids?

It is necessary to act in stages:

  1. Determine the concentration of Testosterone;
  2. Use a sterile syringe and needle (pre-select the appropriate size, taking into account the oily texture of the drug);
  3. Wash your hands and put on sterile gloves (do not touch non-sterile objects, if this happens, change your gloves);
  4. Collect the required dose in the syringe (a thicker needle is used);
  5. For the introduction of the drug, it is desirable to change the needle to a thinner one in order to reduce the pain;
  6. Squeeze the air out of the syringe (it is important to prevent the entry of air bubbles into the human body in order to avoid an embolism);
  7. Prepare a place for injection (wipe the area on the body with an alcohol wipe);
  8. Give an injection (before pressing the syringe plunger, it is necessary to delay it slightly).

Side Effects? Can I avoid it with Testosterone Undecanoate?

Even though Testosterone itself may have some side effects that other derivatives have avoided, Testosterone overall is said to be the safest Anabolic steroid. The reason is because it is the Anabolic hormone that the human body produces naturally. That being said, we still need to present you with the possible side effects that can occur with the use of Testosterone Undecanoate. We will point out that the side effects that may occur in both men and women are easy to deal with and well tolerated.

Testosterone itself does produce a mild level of Estrogenic activity, therefore, the possibility of side effects such as Gynecomastia, some water retention and an increase in blood pressure may occur. These are not likely, but we want you to be aware in case you notice the onset of any of the above. When using any Testosterone ester, it is best to have inhibitors on hand such as Clomid or Nolvadex.

Since Testosterone is the prime male Androgen, the possibility of Androgenic side effects does exist. Bouts of acne, oily skin and hair loss (with a history of male pattern baldness) may occur with those who inject Testosterone Undecanoate. Ancillary drugs can be taken to minimize or combat these effects. The most common ancillary drugs include Proscar or Dutasteride. Other uses have reported body and facial hair growth. This includes both male and female users of the steroid.

Cardiovascular strain and negative cholesterol are also things to be on the lookout for when injecting Testosterone Undecanoate. Healthy individuals who use this steroid are less likely to have these side effects. The length of cycle will also play a key role in whether the individual is at risk for these effects. Try to avoid foods high in saturated fats and make cardiovascular activity a daily part of your routine to keep your heart healthy and your cholesterol levels down.

The use of Testosterone Undecanoate is no exception to the rule when we say that steroids suppress the body’s natural production of Testosterone. A complete shut-down is possible, but this will depend greatly on the length of the steroid cycle in addition to how long the user has been taking steroids. Failure to properly run Post Cycle Therapy (PCT) after a steroid cycle will also hinder the body’s natural production of Testosterone. This could lead to more serious health conditions down the road for the user.

Testosterone Undecanoate does not exhibit any measure of toxicity on the liver. This is because the steroid comes in injectable form and does not have to pass through the liver. The oral version of this steroid isn’t toxic to the liver either. When used orally the steroid gets absorbed in the body through the lymphatic system and does not pass through the liver. This is why when taken in the oral form it is recommended that the dosages be administered with the consumption of food, ideally with a higher fat content so that this will maximize the drugs absorption.

The main requirement for taking a steroid of any kind, is to use them safely. Testosterone Undecanoate can be associated with such problems as:

  • Fluid retention;
  • Insomnia, depressed mood;
  • Acne;
  • Increased blood pressure;
  • The appearance of feelings of irritation, aggressiveness;
  • Dryness, itching of the skin;
  • Difficulty urinating;
  • Increased appetite and cholesterol in the blood due to the influence of weight gain.

To ensure that steroid use is safe, it is important not to exceed the recommended dosage, and also not to disturb the duration of the cycle. In addition, it is important to consider the presence of contraindications. If a person experiences individual intolerance to certain components of the drug, has Cancer or problems with the Urogenital system, the drug should be discontinued.

Post Cycle Therapy after Testosterone Undecanoate injections! IMPORTANT INFO!

As stated earlier, Testosterone Undecanoate in injectable form isn’t ran in cycles but if you’re running something with mixed esters and Undecanoate is one of them, start your post cycle therapy 2-3 weeks after the last injection. Clomid and Nolvadex is a good choice for post cycle therapy. If you are running the oral version of Testosterone Undecanoate then start your post cycle therapy 3-5 days before you stop the cycle using the same PCT drugs.

Personal Experience of Testosterone Undecanoate injections: PRO bodybuilder story

I would only use this ester of Testosterone for hormone replacement therapy. In my opinion there is absolutely no need to run this steroid when there is so much better to choose from. Only when retiring from bodybuilding should there be need to use this steroid and even then Cypionate or Enanthate is a much better choice. And the oral form, forget about it! You might as well take the cash and flush it down the toilet. Reason being, you would have to take so many per day to get any results and the most I’ve seen is 120 capsules in a bottle, it would just not be worth it. A user of this type of Testosterone Undecanoate would be going through 3 bottles a month.

  1. What is testosterone undecanoate used for? I have been lifting for years and never heard this type of testosterone come up in conversation.

  2. Testosterone Undecanoate is manly used for TRT. Back in the 1990’s the capsules were popular among bodybuilders. The problem when using the capsules though, they weren’t able to keep consistent levels and found it better to just stick with Enanthate and Cypionate. Nebido is the injectable form for TRT and many on treatment like it due to the long half life and that don’t like injections. Undecanoate has the longest half life of any testosterone ester by far.

  3. No. It doesn’t because levels are to inconsistent when taking Andriol. Only small amounts of the hormone make it into the blood compared to D-bol. Dianabol will give better results.
