Description

Testosterone Undecanoate – Test Libido 250mg is a slow-release, oil-based injectable testosterone designed for sustained elevation of testosterone levels. It contains the undecanoate ester, which allows for a very gradual absorption into the bloodstream, providing therapeutic levels of testosterone for several weeks after a single injection.

Clinically, it is used to treat male hypogonadism, improving symptoms such as low libido, fatigue, mood swings, and muscle loss. In bodybuilding and athletic enhancement, Testosterone Undecanoate 250mg is favored by those seeking the benefits of testosterone without the frequent injection schedule required by shorter esters like propionate or enanthate.

Because of its prolonged activity, it is typically injected every 2–4 weeks. This makes it a highly convenient option for long-term hormone therapy, though it takes longer to reach peak levels and also clears from the body more slowly.

Benefits

  • Increases and stabilizes testosterone levels over time

  • Promotes lean muscle growth and strength

  • Enhances libido and sexual performance

  • Improves mood, energy, and recovery

  • Less frequent injections due to long half-life

  • Suitable for long-term testosterone therapy

Side effects
Although Testosterone Undecanoate 250mg is well tolerated, users may experience:

  • Estrogenic effects (water retention, gynecomastia) due to aromatization

  • Suppression of natural testosterone production

  • Acne or oily skin

  • Mood swings or aggression

  • Hair loss in genetically predisposed individuals

  • Possible increase in blood pressure or cholesterol

  • Injection site swelling or discomfort (rare with proper technique)

Proper monitoring, use of aromatase inhibitors, and post-cycle therapy (if applicable) can help minimize these side effects.

Dosages & Protocol

Dosages for Men:

  • Beginner to Intermediate: 250–500mg (1–2ml) every 2–3 weeks

  • Advanced: 500–750mg every 2 weeks (based on response and goals)
    Due to its extended release, injections are typically spaced every 14–21 days. Blood work is recommended to monitor testosterone levels and adjust frequency accordingly

How to administer – reconstitution and how to inject
Testosterone Undecanoate 250mg is a pre-mixed oil-based solution and does not require reconstitution

Injection:

  • Use a 3ml syringe with a 22–25 gauge needle (1.5 inch recommended due to deeper muscle penetration needed for slow-release oils)

  • Inject intramuscularly into the gluteus muscle (preferred site)

  • Clean the injection area thoroughly with an alcohol swab

  • Inject slowly due to the thickness of the oil and large volume per dose

  • Massage the injection area to help disperse the oil and reduce soreness

Storage
Store at room temperature, away from direct sunlight and heat
Keep the vial sealed tightly and avoid refrigeration

Half life & detectability
Half-Life: Approximately 21–34 days, making it the longest-acting testosterone ester
Detection Time: Can remain detectable in the system for up to 3–4 months, depending on dosage, duration of use, and individual metabolism
For athletes subject to drug testing, it is important to consider these detection times and plan accordingly to avoid positive tests for banned substances.

Dosage Instructions

Dosage Instructions

250mg – 350mg / Day

Both forms of Testosterone Undecanoate present challenges when used in a performance enhancement steroid cycle. Most experienced and new steroid users will find Testosterone Undecanoate to be a much less practical and effective choice of compound compared with the much more commonly used esters of testosterone like enanthate.

While a great benefit of this slow acting injection form is how sparse your injections will be, this needs to be weighed up with how long you’ll be waiting to see any results.

If you’re wanting to do a short steroid cycle, then Test Libido won’t fit the bill for you because your cycle length with this compound will need to be at least 16 weeks because of how long this injected hormone takes to start having an effect. 8 or even 12 weeks just doesn’t give Test Libido enough time to take full effect.

Dosage of Test Libido will depend on what your purpose for using it is: as a testosterone support when using other compounds, 1000mg to last 12 weeks is suitable but again, because it is such a slow acting compound it will not provide the immediate relief to testosterone suppression that you’ll be needing so there is unlikely to be a scenario when it will be used in a performance enhancement setting for this purpose.

When using Test Libido as a primary anabolic compound or alongside other steroids in a stack, the dosage of 1000mg can be more frequent, at least once per month or in some cases twice monthly.

Most users will not benefit from a compound like Test Libido that takes a considerable amount of time to kick in, and therefore you are likely to be selecting one of the much faster acting forms of testosterone.

Effect on Cycle

Effect on Cycle

Testosterone Undecanoate, in both oral and injection form, will deliver the same benefits and effects as all esters of testosterone. The testosterone hormone itself is unchanged and retains its 100 anabolic and 100 androgenic rating.

This steroid can be used in two main ways:

  •  as a testosterone replacement at a low dosage during a steroid cycle where you need an external testosterone source to maintain levels and function due to the hormone suppression caused by other compounds
  • Testosterone Undecanoate can itself be used as a performance enhancement compound at higher doses.


The effects that testosterone, when used at high performance enhancement doses, will have on the male body include:

  • Increased nitrogen retention – a positive nitrogen balance is critical for muscle growth. If the nitrogen balance falls into the negative, the body can enter a catabolic state instead of anabolic and muscle will be lost. Testosterone will boost nitrogen retention to a higher level than can be naturally achieved without the use of steroids.
  • Enhances protein synthesis – encourages the cells to make more proteins which fuel muscle growth. Regular resistance training and quality protein food intake also promote protein synthesis, and when combined with a testosterone steroid at high doses this process is significantly enhanced; forming the basis for the substantial muscle mass growth you can achieve when using Testosterone Undecanoate.
  • Increases IGF-1 production – this growth hormone is vital for its anabolic effects on skeletal muscle and in the production of more protein. IGF-I may also stimulate muscle satellite cells which is a process that’s needed to fuel an increase in muscle size.
  • Increases red blood cell count – more red blood cells transporting more oxygen carrying haemoglobin and nutrients to the muscles means better performance, improved endurance and enhanced recovery through the increased removal of acid from cells that oxygen is capable of.
  • Decreases levels of glucocorticoids – these stress hormones naturally increase when undertaking intense physical exercise and they contribute to a loss of muscle mass by causing a loss of protein and having a negative effect on insulin which is an important anabolic regulator. Testosterone can reduce levels of glucocorticoids so you can avoid this muscle wastage and remain anabolic.


If you are experienced using any other form of testosterone such as Cypionate, Enanthate, Propionate or Testosterone suspension, you will be familiar with all the benefits and effects of Testosterone Undecanoate as the hormone is unaltered.

Side Effects

Side Effects

The same expected side effects that come with using any form of testosterone steroid for performance enhancement can be a possible risk when using either the oral or injectable forms of Testosterone Undecanoate. Experienced steroid users will have a good idea of the signs to watch out for, and how to mitigate some of the more serious or undesirable side effects.

The higher the dosage of Testosterone Undecanoate and the longer it’s used for, the higher risk of side effects or more severe effects are likely to be. Most men tolerate taking any form of testosterone well, but everyone has a different risk profile when it comes to potential negative effects.

Here are the main side effects to be aware of when using either the oral or injection form of Testosterone Undecanoate:

Androgenic Side Effects
Side effects relating to androgenic activity will vary between each male user as some guys are much more predisposed genetically to acne and hair loss, while others will have no issues at all in these areas and again, the higher the dosage the more the risk increases of androgenic effects developing.

Female users can expect, even at low doses, to be at risk of virilization symptoms that include a deeper voice and body hair growth, at which point the steroid should be discontinued to allow these effects to subside.

Estrogenic Side Effects
Higher doses of testosterone can result in the development of estrogenic side effects like gynecomastia and water retention due to testosterone converting to estrogen through aromatization. When gyno is left to develop unhindered it can be difficult or impossible to reverse without surgery, and water retention can lead to dangerous increases in blood pressure.

Controlling estrogenic side effects is therefore important, and even more so when you’ll be using other potentially more estrogenic steroids in your cycle. Testosterone is naturally a highly aromatizable steroid, but experienced users should have no issue with controlling these effects. Almost all users will want to make use of an aromatase inhibitor drug during the cycle to combat these effects and prevent them from developing at all. Arimidex is a popular and effective option.

Cholesterol
Low doses for the purpose of testosterone replacement are unlikely to have a noticeably negative impact on cholesterol levels, but studies show that when testosterone is used alongside an aromatase inhibitor, which most users will be doing to combat estrogenic effects, HDL cholesterol levels can decrease.

Those with existing cholesterol problems should monitor levels closely, but all Testosterone Undecanoate users should be sticking with a cholesterol friendly diet with plenty of omega-3 foods and including cardio work in your workouts regularly.

Testosterone suppression
Male users can expect their natural testosterone production to be suppressed when using this steroid, with the more severe suppression occurring the higher your dosage is. In any case, and especially when stacked with other suppressive steroids, a proper PCT plan needs to be in place which will start either towards the end of your cycle or sometime after it, depending on the half-lives of any other compounds you’re using.
