Buy Sustanon 300mg/ml Injection from Mr Pharma

While Testosterone compounds are essentially single esters, Sustanon 300 is a blend of multiple forms of Testosterone in a single product. This product was first developed by Organon for the purpose of treating cases of insufficient testosterone secretion. It is also used by top athletes and bodybuilders to improve their performance. The interest of injectable Sustanon is the presence of esters of varying sizes in a single mixture, which makes it possible to derive benefits very quickly and in a lasting manner. Due to its popularity, buying Sustanon is still quite expensive, but still with a very good cost-benefit ratio. In the United States, it is a product that is only sold on the black market. You must be very careful before buying this compound in front of the multitude of poor quality products that invade the market. Our site is the best steroid site in France. Our products are certified and come from approved laboratories.

How it works?

This product is composed of a mixture of testosterone esters of varying sizes: Testosterone Propionate, Testosterone Phenylpropionate, Testosterone Isocaproate and Testosterone Decanoate. The first 2 esters are small esters which therefore provide fast action. Decanoate, on the other hand, gives lasting results. Isocaproate is an intermediate ester. It is the harmonious arrangement of these shapes that guarantees spectacular results.It is also important to know how to use Sustanon, in order to achieve the intended goals. Buying Sustanon injection is thus very advantageous, as it is a very versatile steroidal compound with remarkable anabolic and androgenic actions. This product acts on several levels:

  • It significantly increases protein synthesis. We know that protein is the first building block of muscle tissue. The faster the protein synthesis, the better the anabolic action on lean matter.
  • It improves nitrogen retention. However, the maintenance of the anabolic context is mainly based on a positive nitrogen balance. since the muscle is made up of 16% nitrogen.
  • It markedly increases the production and release of insulin growth factor 1 (IGF-1). which is actually a peptide hormone produced by all human beings and is highly anabolic in all tissues of the human body.
  • It also increases the number of red blood cells. Red blood cells carry oxygen through the blood to cells in the body. Better oxygenation of muscle tissue leads to better protein synthesis, faster and more efficient recovery and repair.
  • It inhibits the action of glucocorticoids on muscle tissue. Indeed, these stress hormones have a catabolic effect on lean tissue and also promote fat gain. By inhibiting these hormones, testosterone promotes muscle anabolism associated with fat loss.

It should be kept in mind that the Sustanon 300 cycle can cause estrogenic-like side effects, since the esters that compose it are strongly aromatized. Because of its significant androgenic action, this product is not recommended at all for women because of the virilization effects that can be caused by its administration.

There are other dosages of this same product, such as Sustanon 500. You can also buy Boldenone or Deca 300 on our site.

Main Benefits of Sustanon

The positive effects of Sustanon can be observed in case of testosterone replacement therapy in people who have a deficiency of this hormone, which is essential for many functions in the body. The quality of life is thus greatly improved. Indeed, testosterone insufficiency leads to a decrease in libido, erectile dysfunction, loss of muscle mass and strength, an increase in body fat, depression, insomnia, as well as a weakening of the system. immune. It has also been scientifically demonstrated that testosterone deficiency can lead to a number of serious pathologies, such as Alzheimer's disease, osteoporosis and diabetes.

Buying Sustanon can also improve physical performance in bodybuilders and top athletes. The advantages can be seen on several levels, because this product has great versatility of use, which is a considerable asset:

  • At the level of muscle swelling: by ingesting a sufficient number of calories, this product makes it possible to make significant gains in lean mass, while keeping adipose mass at its lowest possible rate.
  • In a cutting cycle: this compound, which contains several forms of testosterone, makes it possible to preserve and protect muscle mass during the fat loss phase, which necessarily involves a very restricted diet in terms of calories and which can thus lead, without supplementation in testosterone, a loss of lean mass, since the body will draw the energy necessary for its functioning.
  • More generally: 300 mg of Susta injection taken regularly and according to the cycle guidelines results in an incomparable improvement in terms of physical endurance, as well as in the overall rate of recovery.

Adverse Effects of Sustanon 300

This product, which is a very powerful anabolic steroid, is very versatile, but can, on the other hand, cause several side effects that we are duty bound to point out to you. It is important to know that these effects are not seen in all people and many will not experience any of them. Their incidence depends essentially on the personal characteristics of each person and their hormonal profile.

Adverse effects of Sustanon 300 fall into 2 broad categories:

  • Estrogenic effects related to the aromatization of testosterone into female hormones, estrogen. The consequences are excess water retention with high blood pressure, development of mammary glands or gynecomastia. This is why it is very important. in order to counteract these Sustanon side effects. to use an aromatase inhibitor. such as Arimidex or Femara. Selective estrogen receptor modulators (SERMs) can also be used. but given their mode of action, they do not offer total protection against these constraining consequences. In addition, they negatively alter blood cholesterol levels in the body. by increasing LDL cholesterol levels and decreasing HDL cholesterol levels.
  • Androgenic-type effects: these effects are linked to the transformation of testosterone into dihydrotestosterone. This can lead to prostate enlargement. as well as hair loss in men who are already predisposed to baldness.

How To Stack With Other Steroids?

Sustanon injection can be combined with other steroids during a cycle, in order to potentiate the anabolic effects. One of the most common and popular combinations is with Dianabol during the first 4 weeks of the cycle at a dose of 40mg per day, to achieve even better results. Sustanon 300 mg can be combined with occasional HCG injections at weeks 4 and 8 to prevent testicular atrophy.
