Testosterone suspension is an injectable preparation containing unesterfied testosterone in a water base. Among athletes, testosterone suspension has a reputation of being an extremely potent injectable, often ranked highest among the testosterones. Very fast acting, testosterone suspension will sustain elevated testosterone levels for only 2-3 days. Athletes will most commonly inject Test Suspension-100 daily, at a dosage of 50-100mg. Although this drug requires frequent injections, it will pass through a needle as fine as a 27gague insulin. This allows users to hit smaller muscles such as delts for injections. Although this drug is very effective for building muscle mass, its side effects are also very extreme. The testosterone in this compound will convert to estrogen very quickly, and has a reputation of being the worst testosterone to use when wishing to avoid water bloat. Gynocomastia is also seen very quickly with this drug, and quite often cannot be used without an anti-estrogen. Blood pressure and kidney functions should also be looked at during heavy use.
Testosterone is the most common anabolic hormone that there is and is also considered the most basic. Due to this, athletes often consider it the base steroid to most all cycles. Testosterone is both anabolic and androgenic in nature. Athletes use Test Suspension-100 to see dramatic gain in muscle size and strength, as well as an overall sense of well being and increases libido and sex drive.
Endogenous androgens are responsible for the normal growth and development of the male sex organs and for maintenance of secondary sex characteristics. These effects include the growth and maturation of the prostate, seminal vesicles, penis, and scrotum; the development of male hair distribution, such as the beard, and pubic, chest, and axillary hair, laryngeal enlargement, vocal-cord thickening; alterations in body musculature; and fat distribution. Drugs in this class also cause retention of nitrogen, sodium, potassium, and phosphorus and decreased urinary excretion of calcium. Androgens have been reported to increase protein anabolism and decrease protein catabolism. Nitrogen balance is improved only when there is sufficient intake of calories and protein.
Androgens are responsible for the growth spurt of adolescence and for the eventual termination of linear growth which is brought about by fusion of the epiphyseal growth centers. In children, exogenous androgens accelerate linear growth rates but may cause a disproportionate advancement in bone maturation. Use over long periods may result in fusion of the epiphyseal growth centers and termination of the growth process. Androgens have been reported to stimulate the production of red blood cells by enhancing the production of erythropoietic stimulating factor.
During exogenous administration of androgens, endogenous testosterone release is inhibited through feedback inhibition of pituitary luteinizing hormone (LH). At large doses of exogenous androgens, spermatogenesis may also be suppressed through feedback inhibition of pituitary follicle stimulating hormone (FSH).
There is lack of substantial evidence that androgens are effective in fractures, surgery, convalescence, and functional uterine bleeding.
Propionate is less polar than free testosterone. TESTO 150® in oil injected intramuscularly is absorbed slowly from the lipid phase; thus, it can be given at intervals of 2 to 3 times/week.
Testosterone in plasma is 98% bound to a specific testosterone estradiol binding globulin, and about 2% is free. Generally, the amount of this sex-hormone binding globulin in the plasma will determine the distribution of testosterone between free and bound forms, and the free testosterone concentration will determine half-life.
About 90% of a dose of testosterone is excreted in the urine as glucuronic and sulfuric acid conjugates of testosterone and its metabolites; about 6% of a dose is excreted in the feces, mostly in the unconjugated form. Inactivation of testosterone occurs primarily in the liver. Testosterone is metabolized to various 17-ketosteroids through two different pathways. The half-life of testosterone as reported in the literature varies considerably; it ranges from 10 to 100 minutes.
In many tissues the activity of testosterone appears to depend on reduction to dihydrotestosterone, which binds to cytosol receptor proteins. The steroid-receptor complex is transported to the nucleus where is initiates transcription events and cellular changes related to androgen action.
INDICATIONS AND USAGE:
Males: TESTO 150® is indicated for replacement therapy in conditions associated with a deficiency or absence of endogenous testosterone:
A. Primary hypogonadism (congenital or acquired)—testicular failure due to cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, or orchidectomy.
B. Hypogonadotropic hypogonadism (congenital or acquired)—idiopathic gonadotropin or LHRH deficiency, or pituitary-hypothalamic injury from tumors, trauma, or radiation.
If the above conditions occur prior to puberty, androgen replacement therapy will be needed during the adolescent years for development of secondary sexual characteristics. Prolonged androgen treatment will require to maintain sexual characteristics in these and other males who develop testosterone deficiency after puberty.
C. TESTO 150® may be used to stimulate puberty in carefully selected males with clearly delayed puberty that is not secondary to a pathologic disorder; puberty is expected to occur spontaneously at a relatively late date. Brief treatment with conservative doses may occasionally be justified in these patients if they do not respond to psychologic support. The potential adverse effect on bone maturation should be discussed with the patient and parents prior to androgen administration. An x-ray of the hand and wrist to determine bone age should be obtained every 6 months to assess the effect of treatment on the epiphyseal centers (See WARNINGS).
Females: TESTO 150® may be used secondarily in women with advancing in operable metastatic (skeletal) mammary cancer who are 1 to 5 years postmenopausal. Primary goals of therapy in these women include ablation of the ovaries. Other methods of counteracting estrogen activity are adrenalectomy, hypophyscctomy, and/or antiestrogen therapy.
This treatment has also been used in premenopausal women with breast cancer who have benefited from oophorectomy and arc considered to have a hormone-responsive tumor. Judgement concerning androgen therapy should be made by an oncologist with expertise in this field.
Propionate has been used for the management of postpartum breast pain and engorgement. (There is no satisfactory evidence that this drug prevents or suppresses lactation.)
Propionate is contraindicated in men with carcinomas of the breast or with known or suspected carcinomas of the prostate and in women who are or may become pregnant. When administered to pregnant women, androgens cause virilization of the external genitalia of the female fetus. This virilization includes clitoromegaly, abnormal vaginal development, and fusion of genital folds to form a scrotal-like structure. The degree of masculinization is related to the amount of drug given and the age of the fetus and is most likely to occur in the female fetus when the drugs are given in the first trimester. If the patient becomes pregnant while taking these drugs, she should be apprised of the potential hazard of the fetus.
In patients with breast cancer, androgen therapy may cause hypercalcemia by stimulating osteolysis. In this case, the drug should be discontinued.
Prolonged use of high doses of androgens has been associated with the development of peliosis hepatitis and hepatic neoplasms, including hepatocellular carcinoma (See PRECAUTIONS-Carcinogenesis). Peliosis hepatic can be a life-threatening or fatal complication.
Geriatric patients treated with androgens may be at an increased risk for the development of prostatic hypertrophy and prostatic carcinoma.
Edema with or without congestive heart failure may be a serious complication in patients with preexisting cardiac, renal, or hepatic disease. In addition to discontinuation of the drug, diuretic therapy may be required.
Gynecomastia frequently develops and occasionally persists in patients being treated for hypogonadism.
Androgen therapy should be used cautiously in healthy males with delayed puberty. The effect on bone maturation should be monitored by addressing bone age of the wrist and hand every 6 months. In children, androgen treatment may accelerate bone maturation without producing compensatory gain in linear growth. This adverse effect may result in compromised adult stature, the younger child, the greater risk of compromising final mature height.
Do not give propionate to elderly asthenic males who may react adversely to overstimulation by androgens.
LIVER CELL TUMORS ARE REPORTED. MOST OFTEN THESE TUMORS ARE BENIGN AND ANDROGEN DEPENDENT, BUT FATAL MALIGNANT TUMORS HAVE BEEN REPORTED. WITH DRAWAL OF DRUG OFTEN RESULTS IN REGRESSION OR CESSATION OF PROGRESSION OF THE TUMOR. HOWEVER, HEPATIC TUMORS ASSOCIATED WITH ANDROGENS OR ANABOLIC STEROIDS ARE MUCH MORE VASCULAR THAN OTHER HEPATIC TUMORS AND MAY BE SILENT UNTIL LIFE-THREATENING INTRA-ABDOMINAL HEMORRHAGE DEVELOPS.
PELIOSIS HEPATIS, A CONDITION ARE ALSO REPORTED IN WHICH LIVER AND SOMETIMES SPLENIC TISSUE IS REPLACED WITH BLOOD-FILLED CYSTS, HAS BEEN REPORTED IN PATIENTS RECEVING ANDROGENIC ANABOLIC STEROID THERAPY. THESE CYSTS ARE SOMETIMES PRESENT WITH MINIMAL HEPATIC DYSFUNCTION, BUT AT OTHER TIMES THEY HAVE BEEN ASSOCIATED WITH LIVER FAILURE. THEY ARE OFTEN NOT RECOGNIZED UNTIL LIFE-THREATENING LIVER FAILURE OR INTRA-ABDOMINAL HEMORRHAGE DEVELOPS. WITHDRAWAL OF DRUG USUALLY RESULTS IN COMPLETE DISAPPERRANCE OF LESIONS.
BLOOD LIPID CHANGES THAT ARE KNOWN TO BE ASSOCIATED WITH INCREASED RISK OF ATHEROSCLEROSIS ARE SEEN rN PATIENTS TREATED WITH ANDROGENS AND ANABOLIC STEROIDS. THESE CHANGES INCLUDE DECREASED HIGH-DENSITY LIPOPROTEIN AND SOMETIMES INCREASED LOW-DENSITY LIPOPROTEIN. THE CHANGES MAY BE VERY MARKED AND COULD HAVE A SERIOUS IMPACT ON THE RISK OF ATHEROSCLEROSIS AND CORONARY ARTERY DISEASE.
General Precautions: Propionate , through its metabolic effects, stimulates the nervous, mental, and physical activities of a patient. Therefore, it should be used with caution in the presence of cardiovascular and renal diseases, especially in the elderly male.
Prolonged administration or excessive dosage may cause inhibition of testicular function. As the result, oligospermia may develop, and there may be a decrease in ejaculatory volume. Women should be observed for signs of virilization (deepening of the voice, hirsutism, acne, clitoromegaly, and menstrual irregularities). Discontinuation of drug therapy at the time mild virilism becomes evident is necessary to prevent irreversible virilization. Such virilization usually follows administration of androgens at high doses. A decision may be made by the patient and the physician concerning the degree of virilization that will be tolerated during treatment for breast carcinoma.
Anaphylactoid reactions, although rare, may occur and treatment should be readily available. Hypersensitivity reaction including rash and dermatitis have been reported.
Information for the Patient
The physician should instruct patients to report any of the following side effects of androgens.
Adult or Adolescent Males: Too-frequent or persistent erections of the penis.
Women: Hoarseness, acne, changes in menstrual periods, or more hair on the face.
All Patients: Any nausea, vomiting, changes in skin color, or ankle swelling.
Any male adolescent patient receiving androgens for delayed puberty should have bone development checked every 6 months.
1. Women with disseminated breast carcinoma should have frequent determinations of urine and serum calcium levels during the course of androgen therapy (See WARNINGS).
2. Periodic (every 6 months) x-ray examinations of bone age should be made during treatment of prepubertal males to determine the rate of bone maturation and the effects of androgen therapy on the epiphyseal centers.
3. Hemoglobin and hematocrit should be checked periodically for polycythemia in patients who are receiving high doses of androgens.
Drug/Laboratory Test Interferences
Androgens may decrease levels of thyroxine-binding globulin, resulting in decreased total T4 serum levels and increased resin uptake of T3 and T4. Free thyroid hormone levels remain unchanged, however, and there is no clinical evidence of thyroid dysfunction. Carcinogenesis
Animal Data: testosterone has been tested by subcutaneous injection and implantation in mice and rats. The implant induced cervical-uterine tumors in mice, which metastasized in some cases. There is suggestive evidence that injection of testosterone into some strains of female mice increases their susceptibility to hepatoma, testosterone is also known to increase the number of tumors and decrease the degree of differentiation of chemically induced carcinomas of the liver in rats.
Human Data: There are rare reports of hepatocellular carcinoma in patients receiving longterm therapy with androgens in high doses. Withdrawal of the drugs did not lead to regression of the tumors in all cases.
Geriatric patients treated with androgens may be at an increased risk for the development of prostatic hypertrophy and prostatic carcinoma.
Usage in Pregnancy-Pregnancy Category X Teratogenic effects (See CONTRAINDICATIONS).
It is not known whether androgens are excreted in human milk, because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from androgens, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Androgen therapy should be used very cautiously in children and only by specialists who are aware of the adverse effects on bone maturation. Skeletal maturation must be monitored every 6 months by an x-ray of hand and wrist (See INDICATIONS AND USAGE and WARNINGS).
There have been no reports of acute overdosage with the androgens.
DOSAGE AND ADMINISTRATION:
Propionate® is administered by intramuscular injection. It must not be given intravenously. Intramuscular injections should be given deep in the gluteal muscle.
The suggested dosage varies, depending on the age, sex, and diagnosis of the individual patient. Dosage is adjusted according to the patient's response and the appearance of adverse reactions, and maintenance doses should be the minimum that produce adequate effect. This preparation is absorbed relatively slowly, and frequent injection may cause overdosage. Replacement therapy in androgen-deficient males should be in the range of 25-50 mg 2 or 3 times a week.
Various dosage regimens have been used to induce pubertal changes in hypogonadal males; some experts have advocated lower dosages initially, gradually increasing the dose as puberty progresses. With or without a decrease to maintenance levels. Other experts emphasize that higher dosages are needed to induce pubertal changes, and lower dosages can be used for maintenance after puberty. The chronologic and skeletal ages must be taken into consideration, both in determining the initial dose and in adjusting the dosage.
Dosages used in delayed puberty generally are in the lower ranges and are for a limited duration, for example, 4 to 6 months.
Carcinoma of the Breast: In inoperable carcinoma of the breast, temporary palliation may be obtained in some cases by therapy with androgens. A dosage of 50-100 mg of propionate^ administered intramuscularly 3 times weekly is recommended. If a response to androgen therapy is going to occur, it will be apparent within 3 months after initiation of therapy. When the disease again becomes progressive, therapy should be stopped and the patient observed for another period of improvement, known as rebound regression. The above high dosage is likely to have masculinizing effects, particularly in young women. There may be a disturbing increase in libido, for which sedation may be helpful. It should be remembered that acceleration of tumor growth may be encountered occasionally during androgen therapy, in which case immediate cessation of the hormone is indicated. In some of these cases, the use of estrogen at this point causes regression.
Postpartum Engorgement of the Breasts: A dosage of 25 to 50 mg of propionate daily for 3 to 4 days, starting at the time of delivery, should be adequate in most cases.
Body building: male 350-2000 mg per week, female 50-100 mg per week.
