History and Overview of Neotest 250:

Neotest 250 is a Testosterone Decanoate which is usually used as a veterinary medicine and is constructed from a single large ester made from Testosterone Decanoate compound. In fact, the single ester compound is one of the largest esters available on the market and it can only usually be obtained as part of a blended mix. Typically, Neotest’s single ester compound is found as part of many testosterone blends and can be found in compounds such as Sustanon 250 and the more recent proprietary mix of Omnadren. At the time of writing, Neobrand is no longer available for sale as a veterinary medication

Neotest was manufactured in Mexico by the company known as Loeffler primarily as a veterinarian grade injectable anabolic steroid. It is perhaps one of the best-known manufacturers that found themselves being stopped in their tracks with manufacturing Neotest 250 as part of the DEA’s Operation Gear Grinder. Ultimately the DEA’s involvement put an end to Loeffler’s production of Neotest 250 and it can now only be found as a component in one of many testosterone blends.

Of course, there is always a chance that you may be able to find a laboratory that is producing a similar or a generic version of Testosterone Decanoate, and you may even find one who is using the Neotest 250 branding and logo. However, chances are that it will not be Neotest, and you will have a hard time finding an underground lab which produces it. That said, if the individual is able to find a lab that produces Testosterone Decanoate or a lab that they are on good terms with, they may be able to have it custom manufactured for them. While it is a possibility, there is not much need for it as Testosterone Enanthate and Testosterone Cypionate both work in the same way. If you are looking for a large single ester testosterone compound, then either of the latter two will fulfil your needs.

Neotest 250 Properties and Actions:

Testosterone Decanoate has many different brand names, however, Neotest 250 is the one that the majority of people will recount if asked about the compound. It is a long Decanoate ester that the testosterone is attached to. Testosterone Decanoate is an injection version of testosterone and not a tablet or pill form. When talking about esters, the ester in Testosterone Decanoate has no bearing on the functions or traits of the compound. There is not a single ester with the ability to interfere with the functions of testosterone. That being said, the ester does play a role in how quickly or slowly the testosterone hormone is released into the system. The speed as to which Testosterone Decanoate is released is at the very slow end of the spectrum and provides a steady and consistent release of hormone after just one single injection.


As with all testosterone preparations, Testosterone Decanoate carries an androgenic score 100/100. The score or rating basically represents the baseline rating which is used across the board to measure each and every anabolic steroid. Testosterone Decanoate carries a moderate to long active half-life and will last a few days longer than Testosterone Cypionate. Being a testosterone hormone makes Neotest 250 an ideal solution for the treatment of low testosterone condition, and while it is a synthetic version of testosterone, once in the system the body cannot differentiate between natural and man-made hormone.

As it currently stands, Testosterone Decanoate is not prescribed as a low testosterone condition medication, with the exception of testosterone mixes containing the compound such as Sustanon 250 & Omnadren. The large Testosterone Decanoate ester can be found in both of the aforementioned medications and both were created with the intention of treating low testosterone condition. The original blend of Omnadren didn’t carry a Testosterone Decanoate ester, but the Caproate ester. However, the current day blend contains Testosterone Decanoate and are mixed in a 1ml ampule. This gives a total dose of 250mg which consists of the following:

– Testosterone Decanoate at 100 mg

– Testosterone Phenylpropionate at 60 mg

– Testosterone Propionate at 30 mg

– Testosterone Isocaproate at 60 mg

Regardless of the fact that Testosterone Decanoate can be found in testosterone blends which have been created with the intention of treatment of low testosterone condition and TRT, or testosterone replacement therapy, Neotest’s original use was as a performance-enhancing treatment. While Neotest 250 was a veterinary grade compound it was because of who Loeffler was aiming it at that saw the DEA target them and close it down. While Neotest 250 is no longer in existence, its traits and functions represent the desirable effects which are sought after by athletes for performance enhancement. Testosterone Decanoate is an extremely functional anabolic steroid which can assist with the following:

Enhanced Retention Of Nitrogen: The muscle tissue, which is found throughout the body is made up of around sixteen percent nitrogen. When the nitrogen levels in the muscles fall, muscle wasting can occur (Catabolic Effect). Therefore, when the levels of nitrogen are increased in the muscles, then the anabolic atmosphere improves and increases, which can assist with recovery, preservation of muscle, and improved muscle growth.

Enhanced Synthesis Of Protein: The number one building blocks of muscle fibers and tissue are proteins. When talking about protein synthesis, we are talking about the rate as to which cells can build proteins and when the efficiency and utilization are improved. Testosterone Decanoate helps with protein synthesis and leads to better muscular growth.

Red Blood Cell Count Increases: All parts of the body require a constant and steady delivery of oxygen. The red blood cells are like the taxi’s which carry oxygen around our body’s, therefore, if you increase the number of red blood cells in the body you create the delivery of more oxygen throughout the day. Oxygen helps with the endurance of the muscles and can lead to quicker recovery.

IGF 1 Increases: IGF 1 is the common term used for Insulin-Like Growth Factor 1. IGF1 is a hormone which the body naturally produces and is one which is extremely anabolic in nature. The hormone plays a pivotal role in recovery and will assist nearly all of the cells found in the body. The more IGF1 in the body, the better the body is at recovering.

Reduction of Glucocorticoid Production: Anyone who has experienced stress will know how much glucocorticoid hormone can affect the body and in negative ways. While a small amount of the hormone is vital as part of the running of the body, too much of it can lead to the destruction of muscle tissue and the accumulation of body fat. The best way to look at what a Glucocorticoid hormone is is to see it as the polar opposite of what an anabolic steroid is. Too much of it and it has negative impacts on the physique and all-around general health and well being of the individual. Testosterone Decanoate can help keep Glucocorticoid levels in check and prevent them from becoming dominant in the body.

Neotest 250 Effects:

Now we know how the functions & traits of Testosterone Decanoate and Neotest 250 work, we have a better general knowledge of the compound itself. That said, it is best to look at the compound in a more practical way. Mainly so that the user will know what to expect from its use should they opt to try it.

Neotest 250’s effects on low testosterone condition are rather simple. If you are afflicted with low testosterone condition then your body is not producing enough of the hormone naturally. The causes of low testosterone condition can vary and could be caused by any one of a number of conditions. The common symptoms of low testosterone condition are as follows:

  • A complete or partial loss of libido or sexual interest.
  • The inability to obtain or keep an erection – Erectile Dysfunction.
  • An increase in the amount of body fat being deposited, especially on the hips and chest.
  • A reduction in muscle mass even when diet and exercise are optimal.
  • A reduction in body strength, even when diet and exercise are optimal.
  • Lethargic feelings, including tiredness, wanting to sleep more often and reduced mobility.
  • The inability to be able to fall asleep or stay asleep –insomnia.
  • A weak immune system, leading to more illnesses than normal.
  • Mood changes, including becoming easily irritated and emotional.
  • Lack of energy, sleeping more than normal, lack of motivation.
  • Depression and low moods which can last for days at a time.
  • Brain fog and the inability to concentrate.
  • Loss of focus or an increasingly short attention span.

To remedy the above-mentioned symptoms that may occur with low testosterone condition Neotest 250 will increase the amount of active free-flowing testosterone in the body and eradicate the symptoms. When you have sufficient testosterone in the body, you also negate the risks of developing Alzheimer’s, prostate cancer, heart disease and osteoporosis.

Your age is irrelevant, if you are afflicted with low testosterone condition and any of the symptoms listed above affect you, then Neotest 250 can help remedy the situation and restore your natural functions.

For athletes looking to enhance their performance capabilities, then the benefits can prove to be good for both in season and off-season athletes. To begin with, the off-season athlete will find Neotest 250 to be a fantastic steroid which helps promote the development of lean muscle mass. The higher the levels of testosterone in the body, the more you can expect to grow and get stronger. Neotest 250 also promotes the loss of body fat and helps the off-season athlete keep a trim physique without losing muscle mass. It is also important to note that higher levels of testosterone encourage the body’s metabolism to remain high, and while an off-season athlete can expect to gain a certain amount of body fat, they will be able to make better use of the calories they consume.

Next up, the cutting or dieting athlete will also be able to benefit from the powerful effects of Neotest 250. When an athlete is in a cutting phase and attempting to lose body fat, it can be difficult to maintain and hold on to their lean muscle tissue, which can, unfortunately, be lost quite quickly when on a calorie deficit diet. However, Neotest 250 enables the athlete to be able to hold on to their lean muscle mass even when dieting.Not only that, but he or she will discover that they can cut fat quite quickly due to the powerful metabolism boosting effect testosterone has on the body.

The long and short of it is that anyone who decides to supplement with Neotest 250 will discover that as their testosterone levels increase, so does the size and strength of the lean muscle mass and their rate of recovery improves too. These benefits help create a more powerful and efficient athlete.

Side Effects Of Neotest 250:

As with all anabolic steroids, side effects are possible and Neotest 250 is no exception in this regard. However, it does prove to be one of the better-tolerated versions available, especially among healthy adult males.

For those men who are suffering from low testosterone condition, encountering complications are quite rare as, in effect, all you are doing is replacing the testosterone that your body should be producing, but isn’t. The potential side effects of using Neotest 250 are still a possibility, but if you keep to the specified dose guidelines you should be able to mitigate any risks. The reason that dosing is important is that the higher the dose is, the higher the likelihood of side effects becomes. The majority of men will be able to tolerate Neotest 250 quite well, but each individual may react differently. To help you get a better understanding of how Neotest 250 may affect you, we have placed the potential side effects in smaller categorised sections.

Estrogenic Side Effects: Estrogenic side effects are possible with Neotest 250 with the most common estrogenic side effect experienced being water retention. Testosterone can and does aromatize and convert to estrogen in the body. The use of an AI (Aromatase Inhibitor) is optional and can help reduce the amount of aromatization that takes place in the body, however, AI’s can also present their own sets of problems. AI’s examples are Aromasin and Arimidex. The second option is to use a SERM (Selective Estrogen Receptor Modulator), such as Clomid or Nolvadex to help reduce estrogenic effects. Of the 2 choices, SERM’s are a better option as they present less risk of side effects.

Androgenic Side Effects: 250 has the potential to cause androgenic side effects. Some of the more common androgenic side effects include as hair loss, increase in body hair, and acne. Testosterone is metabolized by the 5-Alpha-reductase enzyme and reduces down to DHT from the influx of testosterone. Hair loss is a major cause for concern for many men, but If you don’t have MPB (*male pattern baldness) in your genetics, then there is no way that Neotest 250 can cause hair loss or balding. Men who do have MPB may find that the increase in testosterone can lead to hair loss and the problem is exasperated or sped up.

Cardiovascular Side effects: Neotest 250 can have an effect on the good cholesterol or HDL, which may be reduced and the bad cholesterol, LDL, which may increase. There is also a risk that testosterone may thicken the blood by increasing the levels of haemoglobin and red blood cell numbers. That said, those who use Neotest for therapeutic purposes and within the specified dosing guidelines should not suffer any major impact on their cholesterol. Should the individual be using an AI alongside Neotest 250, then issues may arise, so if possible it is best to avoid using AI’s altogether.

Hepatoxicity Risks: The use of Neotest 250 has shown to be nontoxic to the liver and presents no risks to the individual when using it.

Testosterone Inhibition: Neotest 250 will lead to the suppression of the body’s ability to naturally produce testosterone. If you already have low testosterone levels, then this will have no effect on you or your treatment plan. All anabolic steroids have the ability to suppress testosterone production, and some more so than others. Neotest 250 is known to cause significant reductions in natural testosterone production.

Once treatment with Neotest 250 comes to an end, it will be important to perform post cycle therapy to help kick-start the body’s natural production of testosterone. As soon as all of the exogenous hormones have left the system the individual can expect their own testosterone production to begin. However, if the individual was suffering from low testosterone condition before starting Neotest 250 then their natural testosterone production will only be as strong as it was before treatment. To help the body begin producing its own natural testosterone again, a PCT plan can help and is highly recommended.

How To Administer Neotest 250:

Due to the fact that the manufacture of Testosterone Decanoate as a large single ester is no longer available, it will not be prescribed as a treatment option for those suffering from low testosterone condition and can only be found as a mix or blend of another testosterone supplement. If you are trying to find Neotest 250 on the black market, you are going to find that it is almost completely unheard of. The only way you will find it on the black market is as a blend with Omnadren or Sustanon. That said, if you do happen to chance upon a Testosterone Decanoate supplement online, then a dose of around 500mg each week will garner fantastic results for the individual, especially regarding performance enhancement.

500mg of Testosterone Decanoate will also prove to be just about all of the testosterone any man could need. If the individual has a strong tolerance level to Neotest 250, then higher doses may be used and many males can dose with 750mg – 1000mg. In fact, it is quite common for most men to dose at higher levels than 500mg and it will all depend on the individual’s tolerance for it. However, a word of warning when using a higher dose, and that is that the higher the dose is, the more likely you are to experience side effects, so an element of caution is advised when taking larger amounts of Neotest 250. Neotest is also a good choice for those who are suffering from testosterone suppression caused by the use of other anabolic steroids. It is true that some athletes prefer to use different anabolic steroids to help with performance enhancement, but testosterone suppression is inevitable and thus exposure to exogenous testosterone will be required. A dose of 250mg roughly every 7 to 10 days will be more than enough hormone to get things back on track.

Warning About Buying Neotest 250 Online:

As Neotest 250 no longer manufactured and doesn’t exist anymore, you will not be able to find it for purchase online. However, there is always the chance that you may find a generic version being sold by an underground pharmacy or on the black market, although this will be rare at the best of times. Depending on where you live, different laws may apply to the purchase of Testosterone Decanoate. As an example, Testosterone Decanoate is classed as a Schedule III controlled substance, as all anabolic steroids are. Purchasing it without a genuine doctor’s prescription would be breaking the law and if caught you could face a hefty fine, jail time, or both.


Unfortunately, there is not much more that can be said about Neotest250 due to the fact that it is no longer in existence. If you do happen to find Neotest 250 or a generic Testosterone Decanoate product, its use will result in identical effects as provided by Testosterone Enanthate and Testosterone Cypionate. If you do want to try Testosterone Decanoate, then you will be able to find it as part of the blend in Omadren and Sustanon-250.
