Testosterone Propionate

Testosterone propionate as a water-oil solution of Pharmacom Labs are proven quality and effect of sporting. Like all forms of testosterone, and that fast-acting ester is no exception, and admission gives him powerful buildup of muscle mass and strength.

What is Testosterone Propionate?

PHARMA TEST P 100 (Testosterone Propionate) is one of top-selling products of Pharmacom Labs. It is highly recommended as the base of both mass building and cutting cycles. Testosterone is responsible for promoting health and well-being through enhanced libido, energy, immunity, increased fat loss, gaining and maintaining lean 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 (preferably short esters) as part of a potent stack. 


Test P100 allows you to increase muscle mass, blocks catabolic effects, increases strength and improves body relief. Due to the fact that this drug retains water in small quantities, the increase in muscle mass occurs gradually and evenly, and the muscles themselves are sufficiently high quality and dry. Even a light solo cycle, for a period of 6-8 weeks, 50 mg every other day, will allow the beginner to gain 2-3 kg of high-quality muscles.

When ingested, propionate is rapidly absorbed, raising the level of anabolic hormones in the blood. Literally 3-4 hours after the injection, you can feel cheerfulness and a surge of strength. The maximum concentration in the blood of this drug accounts for 24 to 36 hours after injection.

Side effects

Propionate is easily aromatized and turns into estrogen, therefore it can occur:

Gyncomastia (you need to be careful not to have female boobs, take tamox 20-40 mg/day).
Acne (Acne).
Hair loss (or active growth on the body) also depends on the individual characteristics of the organism of a particular person.
Lowering the production of your own testosterone, but it is usually restored at the end of the prima drug (at the end of the course) in 2-3 months.

Effect to Bodybuilders

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).


Testosterone with propionate ester chain is one of top-selling products of Pharmacom.Labs; it is used mostly for quality muscle bulk gain, as well as in courses aimed at decrease of bodyweight and get ripped.

Testosterone, as the natural product drug and one of the most widely used anabolic steroids, is the most convenient choice for a reference drug to which all others will be compared. And while it is entirely possible to construct maximally-effective steroid cycles without employing testosterone, most do not do this, but instead use testosterone as their foundation. Either approach can be entirely sound.

As a bodybuilding drug, testosterone is almost always used as an injectable ester, due to poor oral bioavailability and the impracticality of high dose transdermal or sublingual delivery. Testosterone also is provided as an injectable suspension. Discussion here is in reference to these injectable preparations.

Pharmacologically, testosterone acts both via the androgen receptor and via other means. In practice, it is found to combine synergistically both with those anabolic steroids categorized as Class I and those categorized as Class II, and therefore is described as having mixed activity.

Particular properties of testosterone that are of note include that it converts enzymatically both todihydrotestosterone (DHT) and to estradiol (the most important of the estrogens.)

While with normal levels of testosterone and normal enzyme activity these conversions are in fact desirable, with supraphysiological testosterone levels caused by drug administration they can be undesirable. DHT is at least three times more potent (effective per milligram) than testosterone at the androgen receptor (AR): therefore, in those tissues which convert testosterone to DHT, there is effectively three times as much androgen as elsewhere in the body. Thus, whatever level of androgen is experienced by the muscle tissue is effectively multiplied threefold or more in the skin and in the prostate. This can be excessive.
