Testosterone Propionate Facts

Testosterone is a sex hormone present in males and females. In males, this hormone regulates the normal development and functions of body systems such as bones, muscles and genitalia. Testosterone is directly related to masculine traits such as a deep voice, libido, aggressive behaviour and a muscular physique. The hormone enables the muscles to store higher amounts of nitrogen. In turn, this enhances protein synthesis and therefore produces greater muscle mass.

Testosterone medication may be prescribed to allow sexual maturity of adolescent boys experiencing delayed puberty. Since the therapy may be detrimental to normal bone growth and result in stunted height, bone development needs to be monitored during treatment.

Testosterone propionate is a synthetic testosterone with the added propionate ester (chemical compound). The oil-based injectable compound is used as a treatment for androgen deficiencies and also for body building purposes. It’s among the first anabolic androgen steroids ever developed for mass production. Testosterone propionate is a fast-acting and short-lived ester. After injection, testosterone levels peak and wane quickly. Therefore, the drug must be administered every other day throughout the cycle for optimum results and for maintaining stable blood test levels.

Users of this steroid have reported some irritation, discomfort and redness at the injection site. More sensitive individuals may have lower tolerance levels to the drug. It may trigger reactions such as body soreness, nausea, vomiting, low-grade fever and headache. Some people may be allergic to the drug or its inactive ingredients. The signs of allergic reaction are breathing problems, extreme dizziness, swelling and itching of the face, throat and tongue, and skin rashes.

A major drawback is that the anabolic steroid is converted into estrogen in the body. The excess build-up of the hormones estrogen and dihydrotestosterone results in feminine characteristics. Typical side effects include gynocomastia (abnormal growth of mammary glands, resulting in enlarged male breasts) and shrinking of testicles. Other possible negative outcomes are blood pressure and cholesterol issues and water retention.

Individuals who develop gynocomastia and water retention need to neutralise these effects with an anti-estrogen or an aromatase inhibitor. The testicles revert to normal size once natural production of testosterone is resumed. A healthy diet supplemented with omega fats, as well as regular cardiovascular exercise, are required to stabilise blood pressure and cholesterol levels.

Other undesirable androgenic consequences include aggressiveness, increase or decrease in libido, more pronounced hair growth on the face and body, changes in skin hue, oily skin and acne. The propionate ester may also worsen the condition of individuals already predisposed to male pattern baldness. A counteracting treatment regimen may be needed, but there are no guarantees to minimise hair loss. Testosterone products inhibit the body’s natural production of testosterone. To combat the crash, a drug to stimulate testosterone may be prescribed.

The treatment cycle may last from 8 weeks to 16 weeks. Whatever the duration, a post-cycle therapy is required. After an extended treatment or high-dosage use, withdrawal symptoms may be experienced such as depression, fatigue and weakness. A gradual dose reduction is imperative to resume the body’s normal functions and avoid withdrawal reactions.

More acute negative side effects have been reported in some cases. Some users may show signs of liver failure (abdominal pain, dark-coloured urine, fatigue, nausea, jaundiced skin and eyes). Other individuals may suffer shifts in mood or mental states (anxiety or anger issues), disruption in sleeping patterns and snoring. The drug may also lower sperm counts and male fertility.

Male users should visit the doctor right away if they experience problems with passing urine, tenderness or swelling of the breasts, and unusual frequency or duration of erections. If the erection is painful and lasts for over 4 hours, they must promptly discontinue use of the drug and seek medical attention to prevent permanent damage.

Testosterone propionate should not be used by individuals with certain pre-existing medical conditions. Possible adverse effects mentioned here do not comprise an exhaustive list. Interactions with other medications may interfere with treatment or aggravate the risks involved. The fact remains that an increase in the use and dosage of testosterone propionate carries with it greater health risks. Users must consult the doctor immediately if they develop adverse side effects and symptoms.
