1. What is Testosterone decanoate? How does it work?

Testosterone decanoate (5721-91-5) is among the most used steroids on the market by athletes and bodybuilders. The drug is mostly sold under different brands names in various markets, but Neotest 250 has stood out as the most known testosterone decanoate brand. This drug was initially manufactured as a veterinary drug before it was realized it could help bodybuilders to achieve their career goals. Neotest 250 is produced and combined with a single large ester derived from the testosterone decanoate. Actually, this single ester compound is among the largest esters on the market today, and you can only get it as part of a combined mix. The Neotest single ester supplement is used as part of a majority of various testosterone blends such as Omnadren and Sustanon 250 to mention a few.

How does it work?

As mentioned earlier, decanoate is a long ester that is usually attached to various anabolic steroids to enable them to deliver quality results and stay in your body system for a more extended period. Testosterone decanoate (5721-91-5) is an injectable anabolic steroid that means you will have to inject your dosage within the stipulated intervals by your doctor for the entire cycle. Esters don’t interfere with the abilities and functions of testosterone, but it only enables the compound to act for a more extended period. Long esters translate to longer testosterone active half-life in your body while the short esters mean that the drug will have a short active life. The speed at which testosterone decanoate is released in your body ensures a consistent and steady supply for the testosterone hormone and becomes active after just one injection.

Testosterone decanoate(5721-91-5) has an androgenic score of 100/100. These ratings or scores are used in measuring the strength of every anabolic steroid on the market. This steroid has a long and moderate active half-life when injected into your body system than the testosterone cypionate which is said to offer similar results. Therefore, these properties make Neotest 250 the best solution to the treatment of testosterone deficiency. Another best part of the testosterone decanoate is that once injected; your body cannot differentiate it from the natural one meaning you will enjoy excellent results by the end of your cycle.

The drug operates just like the natural testosterone hormone which enhances men characteristics such as the growth of beards, deepening of voice and building of muscles among others. Testosterone hormone is also responsible for the sexual drive more so on men and is recommended for patients who have erectile dysfunction or impotence. However, the natural testosterone hormone might not be enough to enable athletes or bodybuilders to gain the desired body strength and muscles. That’s the reason why many athletes prefer taking steroids to improve the testosterone hormone production in the body. Accompanying your testosterone decanoate dosage with proper diet and workout could make it easy for you to attain your goals within the shortest time possible.

The most common testosterone decanoate(5721-91-5) blends on the market are all developed to solve the low testosterone hormone problem. The original Omnadren had Caproate ester instead of the decanoate ester, but the current blend contains testosterone decanoate ester after the realization that it’s more effective and is mixed with a 1ml ampule. That brings the Neotest compound total dosage to 250mg, and the breakdown is as follows;

  • Testosterone decanoate-100mg
  • Testosterone Phenylpropionate -60mg
  • Testosterone Propionate – 30mgs
  • Testosterone Isocaproate – 60mgs

Another interesting fact about Neotest supplement is that it’s made for enhancing performance, unlike the primary testosterone decanoate which was mainly intended to help patients with low testosterone production problems.  However, even if no known manufacturer is producing Neotest 250, its functions are exactly what every athlete and bodybuilder is looking for to excel in his/her sporting career. Testosterone decanoate is an excellent supplement that helps in improving the red blood cells production in your body, enhance nitrogen retention as well as improve protein synthesis.
