Testosterone Propionate Description:
Testosterone Propionate is the shortest-estered steroid. It's an injectable compound with a slower rate of release than un-esterified Testosterone, but a faster rate of release than all the rest of esterified testosterones.There are some advantages and disadvantages to the short acting ester. The major disadvantage is that users have to inject Testosterone Propionate at minimum every other day throughout the cycle to get proper results. The advantages, however, are easier control and prevention of potential side effects. Also because there is less ester per vial, there is more actual testosterone per injection, which produces better results. The Propionate ester expands Testosterone's half-life to about 4 and a half days.
Biochemistry of Testosterone Propionate
Testosterone Propionate is simply with the Propionate ester bound it's chemical structure. The 'Propionate' is Propionic acid, but once bound to it is known as an ester bond (or ester linkage). Propinoic acid is bonded to the 17-beta hydroxyl group on the Testosterone structure. Esterified anabolic steroids are more fat soluble, and release slowly from the injection site. The main reason for the increased half-life and release rate is because once Testosterone Propionate enters the bloodstream, enzymes work to break the bond between the ester and the testosterone, which takes a varying amount of time - depending on which ester is used. In the end enzymes remove the ester, and what is left is pure Testosterone which is free to do its work in the body. Testosterone alone with no ester bonded to it has a half-life of approximately 2 to 4 hours. When the Propionate ester is bonded to it, the half-life of Testosterone extends to about 4 and a half days.
promotes nitrogen retention in the muscle - the more nitrogen the muscle holds the more protein it can store, and the bigger it gets. Testosterone also increases the body's -1 levels. IGF-1's principal role is to coordinate growth and metabolism. IGF-I is highly dependent on growth to complement it's growth promoting activity.
Intended use of Testosterone Propionate
Testosterone Propionate has been vastly used for medical treatments shortly after its release in the 1930's. Among other it was used for treatment for male androgen deficiency (andropause or hypogonadism), treatment for sexual dysfunction, and treatment for menopause, treatment for chronic dysfunctional uterine bleeding (menorrhagia), treatment for endometriosis. Later on testosterone would only be used for male patients.
Actual use of Testosterone Propionate
Testosterone Propionate is one of the most popular anabolic steroids even today - 80 years after it's invention. It is widely used by bodybuilders and athletes for the purpose of physique and performance enhancement. Testosterone itself is considered the most natural and safest anabolic steroid a person can use. The Propionate ester is suggested for any first time steroid user.

Testosterone Propionate Description:
Testosterone Propionate is a single ester testosterone compound and represents one of the most important testosterone compounds every manufactured. When synthetic testosterone was first created it was in its pure form. Simply put there was no ester attached, thereby providing a fast acting compound that would necessarily require a very frequent administration schedule. In 1937 the pharmaceutical giant Schering out of Germany would release the first ester base testosterone in Testosterone Propionate under the trade name Testoviron. The same trade name it would eventually give to its Testosterone Enanthate product. By attaching the Propionate ester to the hormone, this would allow for the hormone's release time to be controlled and provided a more efficient means in maintaining stable blood levels. Although this was not the first synthetic testosterone preparation created, Testosterone Propionate would become the first commercially available testosterone product. It would also dominate the medical community until the 1960's and much of the newly born performance enhancing community.
Testosterone Propionate Application:
Testosterone Propionate is a pure testosterone hormone. Although synthetic it is a perfect replica of the primary naturally produced male androgen testosterone. By design, the hormone is attached to the Propionate (propionic acid) ester, a small/short ester that enables the hormone's release time to be controlled. Without an ester, the hormone would disperse and dissipate rapidly post administration. By attaching the ester, this promotes a controlled release and allows the individual to inject the hormone less frequently. Once Testosterone Propionate is injected, the ester slowly begins to detach from the hormone. As the ester is detached the testosterone hormone begins to release into the blood. The half-life of Testosterone Propionate is approximately two days, which is substantially longer than ester free testosterone, which carries a half-life a little less than 24 hours.
As a pure testosterone, Testosterone Propionate carries an anabolic rating of 100 and an androgenic rating of 100 as well. The testosterone hormone itself represents the basis by which all anabolic and androgenic ratings are measured in all anabolic steroids. More importantly, while carrying these structural ratings, its translating rating matches up perfectly. Testosterone Propionate will yield a notable amount of anabolic and androgenic activity. This is important as not all steroids match their structural ratings in a translating capacity.
Although synthetic in nature, Testosterone Propionate is an efficient hormone for the treatment of low testosterone. Testosterone is an essential hormone produced by men and women that affects our physical, mental and sexual wellbeing. While produced and essential for both sexes, men require approximately ten times that of women. If you suffer from low testosterone and more than 20 million men in the U.S. suffer from some type of androgen deficiency, Testosterone Propionate will remedy the problem. However, while effective, after all, it is testosterone, it is not a preferred form of treatment as it will require frequent injections. Testosterone Cypionate and Testosterone Enanthate remain the dominant forms in treatment plans. However, if you suffer and Testosterone Propionate is what's available it is a suitable option.
