PHARMA SUST 300 is a trade version of Sustanon from Pharmacom Labs. PHARMA SUST 300 is a testosterone blend that contains four different testosterone esters designed to provide a fast yet extended release of testosterone. This product is manufactured by utilizing high-percentage drug synthesis technology, resulting in a 20% higher concentration of the active agent per mL compared to the standard classical Sustanon version. 

All forms of testosterone are responsible for promoting health and well-being through enhanced libido, energy, immunity, increased fat loss, gaining and maintaining muscle mass, preventing osteoporosis (loss of bone density), and possible protection against heart disease. It combines excellently with many other compounds, both oral and injectable, as part of a potent stack. 

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

Testosterone is the primary man sexual hormone, which directly affects testicles and prostate development, has a large impact on building the muscle tissue, bone density and strength. Moreover, testosterone is to a great extent responsible for dozens of functions in human body: common health, well-being, enhanced libido, energy, immunity, preventing Osteoporosis (loss of bone density), and possible protection against heart disease. Maintaining higher testosterone levels in elderly men has been shown to improve many parameters that are thought to reduce cardiovascular disease risk, such as increased lean body mass, decreased visceral fat mass, decreased total cholesterol, and glycemic control. It determines not only gender differences, but, for example, regulates the population of thromboxane A2 receptors on megakaryocytes and platelets and hence platelet aggregation in humans. It is responsible for behavior, mood, romantic relationships, as per reports it can impact even carrier choice. The studies report that attention, memory, and spatial ability are key cognitive functions affected by testosterone in humans. Preliminary evidence suggests that low testosterone levels may be a risk factor for cognitive decline and possibly for dementia of the Alzheimer’s type, a key argument in life extension medicine for the use of testosterone in anti-aging therapies.

Testosterone is highly favored by athletes for its ability to promote strong increases in muscle mass and strength. As a naturally occurring hormone, it remains the most popular anabolic steroid and is typically used as the base 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 high dose transdermal or sublingual delivery. All testosterone forms in a wide sense are the same: active agent testosterone + ester attached, which determines release time and duration of the compounds active life. In a nutshell: long esters release the active agent into the blood slowly, but provide a stable hormone level for a long time (depending on the ester), without creating peaks.

It shall be noticed, that in men, approximately 5% of testosterone undergoes 5α-reduction to form the more potent androgen, dihydrotestosterone (DHT), also known as androstanolone. From another side approximately 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. Hence, don`t forget to take precautions to avoid respective side effects. Thereof we recommend to perform blood works and take aromatase inhibitors on cycle (if required, anastrozole preferably) and SERMs (clomifene, toremifene) during post cycle therapy (PCT).

Sustanon is the brand name of this injectable form of testosterone steroid. It has a medical use of treating men who have low levels of natural testosterone by acting as a testosterone replacement therapy (TRT).

There are 5 testosterone esters in Sustanon. An ester is an extra chemical addition added to the regular testosterone hormone which is then released in the body after injection. The timing and rate of release of each ester is what makes the four of these different: the testosterone itself is the same on each ester.This makes Sustanon purely a testosterone compound and one what has had no alterations at all to the original testosterone hormone. Testosterone, as the natural male sex hormone, has an anabolic rating of 100 and an androgenic rating of 100 – Sustanon is pure testosterone. Other types of steroids skew these ratings one way or the other based on making modifications to testosterone or similar hormones.So, while Sustanon as pure testosterone comes with many substantial benefits, it also comes with some potential side effects which we need to be aware of and learn how to combat them during a testosterone cycle as well as developing a post cycle therapy plan to recover afterwards. Below is an explanation on each oh the compounds in Sus for interest’s sake.

Testosterone AcetateThis is an exceptionally fast acting form of Trenbolone with a rapid half-life that quickly gets the compound taken up into the bloodstream. It has a half-life of just three days. Acetate includes massive boost to mass and strength, extremely fast results and excellent muscle hardening.

Testosterone PropionateTest Prop is a fast-acting ester with a short half-life of around two or three days. This ester gets Sustanon working quickly to raise blood testosterone levels after administering your injection.

It ensures that Sustanon can get your testosterone levels raised within just 24 to 48 hours of your injection, providing the initial boost at the start while the other esters in Sustanon take their time to release over the next two to three weeks.

Testosterone Propionate injections when taken alone would need to be administered every day, so by making use of this ester in Sustanon you get the full benefit of Testosterone Propionate’s quick acting effects without having to worry about daily injections.Testosterone PhenylpropionateTest Phenylpropionate a relatively fast acting ester but one that can take anywhere from one to three weeks to fully release into the body ensuring it helps maintain a steady supply of testosterone as part of the Sustanon formula.

Testosterone CypionateTestosterone Cypionate is also medium acting ester with a half-life of about 4 days. This is an ester that is not available as an individual product but only consumed in formulas like Sustanon and other mixed testosterone ester preparations.

Testosterone DecanoateTest Decanoate is a slow acting and long-lasting ester that keeps the effects of Sustanon active long after the injection. It has a long half-life of over 20 days.

Just like Cypionate, Testosterone Decanoate is generally not found as a single testosterone ester and instead only included in mixed ester solutions like Sustanon, making this one of the very few ways you can take advantage of the long-lasting benefits of the Testosterone Decanoate ester.
