Testosterone decanoate is an androgen and anabolic steroid and a testosterone ester. It is a component of Sustanon, along with testosterone propionate, testosterone phenylpropionate, and testosterone isocaproate.
Testosterone enanthate is an androgen used to treat low or absent testosterone. Testosterone enanthate is an esterified variant of testosterone that comes as an injectable compound with a slow-release rate. This slow release is achieved by the presence of the enanthate ester functional group attached to the testosterone molecule.2 This testosterone derivative was first approved on December 24, 1953.
Testosterone Cypionate is a synthetic version of testosterone, but it is going to offer the body the same benefits as natural produced testosterone. There are a variety of responsibilities this hormone offers for the male body on a mental and physical level. This includes: fat loss, lean muscle mass, increases bone density, reduces the risk of heart disease, sex drive Testosterone Cypionate is both androgenic and anabolic, making it a great choice if you are looking to gain both strength and size. Those are common goals for athletes and part of why they are encouraged to us this testosterone. It also promotes the retention of nitrogen, and that helps the muscles to develop in less time.
Testosterone decanoate has not been marketed as a single-drug preparation. Testosterone decanoate has been investigated as a potential long-acting injectable male contraceptive.
Administration of ester derivatives of testosterone as testosterone enanthate generates an increase in serum testosterone to levels reaching 400% from the baseline within 24 hours of administration. These androgen levels remain elevated for 3-5 days after initial administration. Continuous administration of testosterone enanthate shows a significant suppression of dihydrotestosterone, serum PSA, HDL and FSH, as well as a slight increase in serum estradiol.
All testosterone, including Testosterone Cypionate, binds to the androgen receptor. This promoters both fat loss and encourages muscle building. As a result, the size and the shape of the muscle fibers can change. The androgens will help to protect the muscle you have created through your diet and workout routine. Testosterone Cypionate is also going to increase the amount of red blood cells to help with endurance. Recovering in less time from strenuous activity will help you to feel better.
Testosterone decanoate has a longer duration of action than testosterone enanthate, but its duration is not as prolonged as that of testosterone undecanoate.
The effects of testosterone in humans and other vertebrates occur by way of two main mechanisms: by activation of the androgen receptor (directly or as DHT), and by conversion to estradiol and activation of certain estrogen receptors. Free testosterone (T) is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT) by the cytoplasmic enzyme 5α-reductase. DHT binds to the same androgen receptor even more strongly than T, so that its androgenic potency is about 2.5 times that of T.
The T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects.
Metabolism: To start its activity, testosterone has to be processed by enzymes in the bloodstream. These enzymes will break the bond between the cypionate ester moiety and the testosterone.
Absorption: Testosterone is an esterified anabolic which allows it to present a greater degree of solubility in fats and thus, the release and absorption occur in a slow rate compare to homologous molecules.5 Intramuscular administration of 200 mg of testosterone produced a mean supratherapeutic Cmax of 1122 ng/dl which occurred 4-5 days post-injection. After the fifth day, the levels of testosterone in plasma went down reaching an average of 400 ng/dl.
Route of elimination: About 90% of a dose of testosterone given intramuscularly is excreted in the urine as glucuronic and sulfuric acid conjugates of testosterone and its metabolites; about 6% of a dose is excreted in the feces, mostly in the unconjugated form.
Half life: The half-life of testosterone is one of the longest, being approximately of 8 days.
