Testosterone Propionate

  • Generic Strattera
  • Testosterone Propionate 100mg Dosage, sold under the brand name Testoviron among others, is an androgen and anabolic steroid (AAS) medication which is used mainly in the treatment of low testosterone levels in men. It has also been used to treat breast cancer in women. It is given by injection into muscle usually once every two to three days. Testosterone Propionate is the shortest-estered testosterone 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 100mg Dosage 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.

    Testosterone propionate was discovered in 1936 and was introduced for medical use in 1937. It was the first testosterone ester to be marketed, and was the major form of testosterone used in medicine until about 1960. The introduction of longer-acting testosterone esters like Testosterone Enanthate 300 For Sale, Testosterone Cypionate Buy, and testosterone undecanoate starting in the 1950s resulted in testosterone propionate mostly being superseded. In addition to its medical use, testosterone propionate is used to improve physique and performance.

    Molecular Formula


    Biochemistry of Testosterone Propionate

    Testosterone Propionate is simply Testosterone with the Propionate ester bound it's chemical structure. The 'Propionate' is Propionic acid, but once bound to Testosterone 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 100mg Dosage 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.

    Testosterone Propionate Benefits

    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.

    Androgens direct the development of the male phenotype during embryogenesis and at puberty. Testosterone is an androgen that is secreted by the testis. This hormone is converted to dihydrotestosterone in the target tissues where it regulates several biological functions. Testosterone propionate has been synthetically derived from a plant. This product has extended and faster-acting functions when compared to other testosterone esters.

    The most common dosage for Testosterone Propionate is:

    50 to 100mg every day
    50 to 100mg every 2nd day

    Every 3rd day should be the absolute minimum because that's near the border of Propionate activity timespan.

    Testosterone propionate use

    Men use it in functional disorders of the reproductive system, eunuchoid, infantilism with congenital underdevelopment of sexual glands or surgical removal of them, with impotence due to lack of gonadal function, nervous and mental exhaustion and fatigue, male menopause and its accompanying vascular and neurological disorders, in the initial stage of prostatic adenoma, acromegaly.

    Women use it for climacteric vascular and neurological disorders (if estrogenic drugs are forbidden) for the treatment of ovarian cancer and breast cancer (under 60 years); dysfunctional uterine bleeding (older women).

    Testosterone is also used in the early stages of hypertension and angina.

    Testosterone Propionate is used in severe forms of chronic hepatitis and cirrhosis with signs of portal hypertension and ascites (based on the effect of testosterone propionate it is supposed to suppress the excessive formation of aldosterone, which is one of the causes of ascites and edema), and is assigned as anabolic, acting on nitrogen and phosphorus metabolism and has several positive effects on metabolism in the liver.

    Testosterone propionate injection

    Testosterone Propionate is used intramuscularly or subcutaneously in oil solutions 0.5-1 mL of 1% or 5% solution of the drug daily, 1-2 days from 2 weeks to 1-2 months. The testosterone propionate therapy is held under the supervision of a physician.

    When eunuchoidism, congenital underdevelopment of sexual glands or surgical removal testosterone propionate dosage is 0.025 g or 0.050 g every other day. With the improvement of the condition the doses are changed to 0,005-0,010 g daily or every other day.

    With impotence due to the lack of gonadal function, nervous and mental exhaustion and fatigue, male menopause and vascular and neurological disorders the dose is 0.010 g daily or 0,025 g 1-2 days.In the initial stage of prostate testosterone propionate 10ml is applied every other day for 1-2 months.In the early stages of hypertension and angina, dose is 0.010 g of 1-2 times a week. The course of treatment is 15-20 injections.With dysmenorrhea the dose is 0,025 grams a day ( 20-30 injections in total).

    In vascular and neurological disorders of the climacteric nature the dose is 0.010 g every other day, a course of treatment is 1-1.5 months.In ovarian cancer and breast cancer (under 60 years) together with both radiotherapy, Testosterone Propionate Injection Dosage is given in the dose of 0,050 g daily for 3-3.5 months and then the dose is reduced to 0,20-0 30 g per week for a month, subsequent two months the dose is 0.15 g per week, and another 2 months-0.10 g, then a maintenance dose of testosterone propionate half-life is prescribed.

    In chronic hepatitis and cirrhosis of the liver in severe form with symptoms of portal hypertension and ascites one of the schemes of intramuscular injection of testosterone propionate in liver is: the first 2 days-1 ml, then 3 days-2 ml, 4 days-3 ml of 1% oil solution of the drug; in the next 7 days-1 ml of 5% oil solution, 4 days-2 ml, and 2 days-1 ml of a 1% solution.

    A high dose of testosterone propionate intramuscularly is: single-0.05 g (1 ml of a 5% solution), daily-0.10 g (2 ml of a 5% solution).

    Testosterone Propionate Side Effects

    A lot of athletes complain on testosterone propionate pain, irritation and redness at the site where the injection was made. And as injections are put often, the surplus of aggression is noticed.

    Propionate is easily flavored and easily converted into estrogen, therefore such things can occur:

    ▪Acne (pimples).
    ▪Hair loss (or active growth on the body) also depends on the individual characteristics of the individual.
    ▪Decrease in natural testosterone, but it is usually restored by the end of the course in 2-3 months.

    Estrogenic side effects of Testosterone:

    The primary side effects of Testosterone Propionate surround its ability to aromatize into Estrogen. Testosterone itself possesses a moderate level of Estrogenic activity - it holds a moderate affinity to bind to the aromatase enzyme (the enzyme responsible for the conversion of Testosterone into Estrogen). Because of that, a moderate level of aromatization is expected from Testosterone use. To counter this problem there are two solutions:

    Selective Estrogen Receptor Modulators (SERMs) like Tamoxifen Citrate (Nolvadex) or Clomifene (brand names: Androxal, Clomid and Omifin) function by binding to the estrogen receptors - filling them and preventing actual estrogen from binding.
    Aromatase Inhibitors (AIs) like Anastrozole (Arimidex) function by inhibiting the aromatase process and even lower the body's own estrogen levels. Aromatise Inhibitors are far more effective than SERMs.

    Water Retention:

    This side effect stems from increased estrogen levels and is countered by aromatase inhibitors (for example Anastrozole - Arimidex).

    Increased blood pressure:

    This is a result of water retention. It is countered by aromatase inhibitors.

    Gynecomastia (aka Gyno / Bitch tits):

    Gynecomastia is the abnormal development of breast tissue in males. Enlargement of the breast tissue is associated with increased estrogen levels. This is countered by Selective Estrogen Receptor Modulators or Aromatase Inhibitors.

    Androgenic Side effects of Testosterone:

    Testosterone androgenic side effects have more to do with the fact that Testosterone is converted into stronger and more potent androgen Dihydrotestosterone (DHT) by the 5-alpha reductase (5AR) enzyme.

    The 5-alpha reductase enzyme is present in large amounts in certain tissues, such as the scalp, prostate, and the skin. When Testosterone reaches these tissues, it undergoes a high rate of reduction into its more potent androgenic metabolite DHT. It is DHT that is responsible for the greater severity of androgenic side effects.

    Hair Loss:

    This side effect is completely dependent on the individual's genetic predisposition. If there are no bald men in your family, this will not be an issue for you. If male pattern baldness runs in your genes you will lose your hair anyway, but testosterone supplementation might speed up the process. This can be countered to some extent with Finasteride and the use of 2% Nizoral (Ketoconazole) shampoo.

    Oily skin:

    Oily skin makes the hair more shiny. In other animals, males with more shiny fur are more desirable/healthier looking.


    Oily skin in turn increases chances of pore clogging and formation of Acne. To some extent this can be countered by the use of Nizoral 2% shampoo, where its active ingredient Ketoconazole acts as a topical DHT blocker in skin and scalp, effectively reducing the probability of androgens triggering male pattern baldness as well as acne breakouts caused by increased oily skin. Acne are usually cleared with the discontinuation of steroids not very long after the discontinuation of the testosterone cycle.


    Studies have shown clear associations between testosterone and aggression. Roid rage a type of impulse control - tendency to overreact to an event that normally wouldn't set you off.

    Shrinkage of testicles:

    When external testosterone is supplemented our natural testosterone production is lowered. The testicles stop producing testosterone because there is plenty of it from external sournce. As a result they temporarily shrink. During the testosterone cycle there isn't much we can do about testicular atrophy. Once the use of external testosterone comes to an end the natural testosterone production is gradually restored and testicles return to their full size. Steroid users speed up recovery by taking Clomiphene citrate (brand names: Androxal, Clomid and Omifin). HCG (Human chorionic Gonadotropin) is also used to rapidly restore natural testosterone production.

    Decreased Libido:

    While supplementing with Testosterone, men often notice a hightened libido (sex drive). Likewise they notice a decrease of libido during the period when testosterone supplementation has ended and before natural testosterone production is restarted again (with clomiphene citrate or HCG).

    In practice, this drug if taken with the mind (in moderation), does not affect internal organs (liver, kidney, etc.). The drug is not recommended to women since it as a high androgynous activity.
