Active: Testosterone Propionate

Testosterone propionate, after Testosterone cypionate and enanthate, is the third injectable testosterone ester that needs to be described in detail. Testosterone propionate is used on few occasions in weightlifting, powerlifting, and bodybuilding not because it is ineffective. Propionate in certain applications it is superior to enanthate, cypionate, and also undecanoate. This is because it has characteristics which the common testosterones do not have.

Main differences between propionate, cypionate, and enanthate

The main difference between propionate, cypionate, and enanthate is the respective duration of effect. In contrast to the long-acting enanthate and cypionate depot steroids, propionate has a distinctly lower duration of effect. The reader learns how long this time is from the package insert of the German Jenapharm GmbH for their compound ”Testosteron Jenapharm” (see list with trade names): ”Testosterone propionate has a duration of effect of 1 to 2 days.” In their book Doping—1/erbotene Arzneimittel im Sport Dr. Dirk Clasing and the well-known professor, Dr. Manfred Donike of the University for Sports Education, Koln state: ”When injected intramuscularly the duration of effect of the testosterone esters depends on the type of esters (Testosterone enanthate and cypionate have longer effects than propionate and acetate) and on the amount of testosterone.

With 50 mg Testosterone propionate i.m. they observed elevated testosterone levels for about 1-2 days. With 250 mg Testosterone enanthate i.m., about 1-2 weeks.” It is a simplification to argue that propionate is only a quickly effective testosterone that must be injected more often. Based on the highly androgenic effect, propionate as well as enanthate and cypionate is very appropriate for the buildup of strength and muscle mass. An eye-catching difference, however, is that the athlete ”draws” distinctly less water with propionate and visibly lower water retention occurs. Since propionate is quickly effective, often after only one or two days, the athlete experiences an increase of his training energy, a better pump, an increased appetite, and a slight strength gain.


As an initial dose most athletes prefer a 50-100 mg injection. This offers two options: First, because of the rapid initial effect of the propionate-ester one can initiate a several week-long steroid treatment with Testosterone Propionate. Those who cannot wait until the depot steroids become effective inject 250mg of Testosterone enanthate and 50 mg of Testosterone propionate at the beginning of the treatment. After two days, when the effect of the propionates decreases, another 50 mg is injected. Two days after that, the elevated testosterone level caused by the propionate begins to decrease.

By that time, the effect of the enanthates in the body would be present, no further propionate injections would be necessary. Thus the athlete rapidly reaches and maintains a high testosterone level for a long time due to the depot testosterones. This is important for athletes who used Anadrol 50 over the six-week period. They gained several pounds and would like to switch to testosterone. When Athletes discontinue Anadrol 50 levels drop sharply. A fast and elevated testosterone level is desirable.

The second option is to take propionate during the entire period of intake. This, however, requires a periodic injection every second day. Athletes can get the best results with 50-100 mg per day or every second day. The athlete, as already mentioned, will experience visibly lower water retention than with the depot testosterones so that propionate is well-liked by bodybuilders who easily draw water with enanthate. A good stack for gaining muscle mass would be, for example, 100 mg Testosterone propionate every 2 days, 50 mg Winstrol Depot every 2 days, and 30 mg Dianabol/day.


In preparation for competition, female athletes mainly use Propionate. During this phase, they often combine dieting with testosterone to maintain muscle mass and muscle density at their maximum. Propionate has always proven effective in this regard since it fulfills these requirements while lowering possible water retention.Using Nolvadex and Proviron can temper water retention. A combination of 100 mg Testosterone propionate every 2 days, either 50 mg Winstrol Depot/day or 100 mg Parabolan every 2 days, and 25 mg Oxandrolone/day help achieve this goal and are suitable for building up ”quality muscles.”


Women especially like propionate. When applied properly, they can avoid androgenic-caused side effects more easily. The trick is to increase the time intervals between the various injections. This allows the testosterone level to fall again so there is an accumulation of androgens in the female organism. Women therefore take propionate only every 5-7 days and obtain remarkable results with it.


The androgenic effect included in the propionate allows better regeneration without virilization symptoms for hard-training women. The dosage is usually 25-50 mg/injection. Higher dosages and more frequent intervals show even better results. However, they do not recommend it for women. The duration of intake should not exceed 8-10 weeks and can be supplemented by taking mild and mostly anabolic steroids such as, Primobolan, Durabolin, and Anavar in order to promote the synthesis of protein.

Side effects

Men who do not fear the intake of testosterone or the possible side effects should give propionate a try. The side effects of propionate are usually less frequent and are less pronounced. The reason is that the weekly dose of propionate is usually much lower than with depot testosterones. A daily injection of 50 mg amounts to a weekly dose of 350 mg while several depot injections easily launch the milligram content of testosterone into the four-figure range. When compared with enanthate and cypionate, propionate is also a ”milder” substance and thus better tolerated in the body. Those convinced that they need daily testosterone injections should consider propionate.

The reader receives interesting information from the package insert of the German Eifelfango Company for its compound Testosterone propionate. Under ”Dosage Instructions and Form of Application” the following is written: “To promote the formation of red blood cells 300 to 750mg (1000 mg per week, if necessary) of Testosteronpropionat-Eifelfango can be taken, divided into 2 to 3 injections per week.”

Large doses

Athletes who want to incorporate 1000 mg into two injections can look forward to a 10ml test cocktail. In our opinion it makes sense to take the propionate once or twice a week in larger quantities. The short duration of effect leads to high fluctuations of the testosterone level. This will result in unsatisfying results and create a hotbed for undesired side effects. The key to success with propionate lies in the regular intake of relatively small quantities (5 0-100 mg every 1-2 days.)

Several powerlifters and weightlifters often inject a larger quantity of Testosterone propionate on the day before the competition so that with high testosterone and androgen levels they can break new records the following day. In particular, the earlier East German weightlifters knew perfectly how to use this technique because they had known for some time that: ”a high testosterone level, in the belief of the East German sports physicians, is absolutely necessary for top performances” (Berendonk, Doping, page 21 9). In competitions with doping tests the additional intake of epitestosterone guarantees a negative test result. Testosterone propionate is excellent in over-bridging. It allows athletes to pass doping tests during immediate preparation for competition.

Dope Testing

The use of the rapidly effective propionate can over-bridge a possible performance breakdown caused by a premature discontinuance of the steroid compounds. In addition, propionate prevents a positive test result. The athlete thus kills two birds with one stone. After the injection of propionate, the T/E value in the urine decreases faster than the testosterone concentration does.

The T/ E value falls below the critical value of six while the performance level is maintained. All the different things propionate can do in this phase are described in detail by Brigitte Berendonk in her book Doping—Von der Forschung zum Betrug: ”Clausnitzer, Hoppner, and Hacker had already pointed out early (1982) that the T/ E value of 6 was too high and that by cleverly timed injections or other forms of application of suitable testosterone esters (e.g. Testosterone propionate) one could exceed the normal range but still test under 6 (p.221).


Thus several male and female athletes in critical training phases could adjust their performance levels without ‘being detected’… Injecting Testosterone propionate raises testosterone levels in the blood (up to more than 250%). The T/E value in the urine rise rapidly as well. After this single injection the T/E value decreases rapidly but the testosterone concentration in the blood falls more slowly. One should note that the T/E value stays at a level above six. This is the threshold value for  positive doping tests. The level persists for more than three days after the injection. Clausnitzer et al. (1) (1982) found out, that with a lower dose of testosterone propionate (25 mg) the threshold value is exceeded only during the first few days.”

Although the side effects of propionate are similar to the ones of enanthate and cypionate they occur less frequently. However, if there is a predisposition and very high dosages are taken, the known androgenic-linked side effects such as acne vulgaris, accelerated hair loss, increased growth of body hair and deep voice can occur. An increased libido is common both in men and women with the use of propionate. Despite the high conversion rate of propionate into estrogen gynecomastia is less common than with other testosterones. The same is true for possible water retention since the retention of electrolytes and water is less pronounced.

HCG and Clomid

The administration of testosterone-stimulating compounds such as HCG and Clomid can, however, also be advised with propionate use since it has a strong influence on the hypothalamo-hypophyseal testicular axis, suppressing the endogenous hormone production. The toxic influence on the liver is minimal so that a liver damage is unlikely (see also Testosterone enanthate). What athletes dislike most about propionate are the frequent injections that are necessary.
