PHARMA TEST E300 (Testosterone Enanthate) is one of the best mass building anabolics known to man and is highly recommended as a base for any mass building cycle. Testosterone is responsible for promoting health and well-being through increased libido, energy, immunity, increased fat loss, increased and maintained lean muscle mass, prevention of osteoporosis (loss of bone density), and possible protection against heart disease. Combines excellently with many other compounds both oral and injectable as part of a powerful stack.

With a half-life of approximately 5-7 days, it is a slow-release ester, similar to PHARMATEST C250 (Testosterone Cypionate).

Synthetic testosterone was first synthesized in 1935 by the German biochemist Adolf Butenandt and the Swiss chemist Leopold Ruzicka who both received a Nobel Prize for their work.

Testosterone is the primary male sex hormone, which directly affects the testicles and prostate development, has a great impact on muscle tissue building, bone density and strength. Furthermore, testosterone is largely responsible for dozens of functions in the human body: health, well-being, increased libido, energy, immunity, prevention of osteoporosis (loss of bone density) and possible protection against heart disease.Maintaining higher testosterone levels in older men has been shown to improve many parameters that are thought to reduce the risk of cardiovascular disease, such as increased lean body mass, decreased visceral fat mass, decreased total cholesterol, and glycemic control. It not only determines gender differences but, for example, regulates the population of thromboxane A2 receptors on megakaryocytes and platelets and thus on platelet aggregation in humans. It is responsible for behavior, mood, romantic relationships, as it can affect the choice of carrier. Studies report that attention, memory and spatial skills are key cognitive functions influenced by testosterone in humans. Preliminary evidence suggests that low testosterone levels may be a risk factor for cognitive decline and possibly Alzheimer's-type dementia, a key topic in life extension medicine for the use of testosterone in anti-aging therapies.

Testosterone is highly regarded by athletes for its ability to promote strong increases in muscle mass and strength. As a natural hormone, it remains the most popular anabolic steroid and is typically used as the basis of all cycles and stacks.

For use in bodybuilding, testosterone is almost always used as an injectable ester or suspension due to poor oral bioavailability and the impracticality of transdermal or sublingual administration at high doses. All forms of testosterone in a broad sense are the same: active testosterone agent + attached ester, which determines the release time and active lifespan of the compounds. In short: long esters slowly release the active agent into the blood, but provide a stable hormone level for a long time (depending on the ester), without creating spikes.

It should be noted that in men about 5% of testosterone undergoes a reduction of 5α to form the most potent gene, dihydrotestosterone (DHT), also known as androstanolone. On the other hand, about 0.3% of testosterone is converted into estradiol (the primary female sex hormone) by aromatase, an enzyme expressed in the brain, liver and adipose tissues. So, don't forget to take precautions to avoid the respective side effects. It is recommended to perform blood tests and take cycle aromatase inhibitors (preferably anastrozole if needed) and SERMs (clomiphene, toremifene) during post cycle therapy (PCT).
