Intramuscular Injection
Intramuscular injection, often abbreviated IM, is the medical injection, injection of a substance into a muscle. In medicine, it is one of several methods for parenteral, parenteral administration of medications. Intramuscular injection may be preferred because muscles have larger and more numerous blood vessels than subcutaneous tissue, leading to faster absorption than subcutaneous injection, subcutaneous or intradermal injections. Medication administered via intramuscular injection is not subject to the first-pass metabolism effect which affects oral medications. Common sites for intramuscular injections include the deltoid muscle of the upper arm and the gluteal muscle of the buttock. In infants, the vastus lateralis muscle of the thigh is commonly used. The injection site must be cleaned before administering the injection, and the injection is then administered in a fast, darting motion to decrease the discomfort to the individual. The volume to be injected in the muscle is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Androgen
An androgen (from Greek ''andr-'', the stem of the word meaning ) is any natural or synthetic steroid hormone that regulates the development and maintenance of male characteristics in vertebrates by binding to androgen receptors. This includes the embryological development of the primary male sex organs, and the development of male secondary sex characteristics at puberty. Androgens are synthesized in the testes, the ovaries, and the adrenal glands. Androgens increase in both males and females during puberty. The major androgen in males is testosterone. Dihydrotestosterone (DHT) and androstenedione are of equal importance in male development. DHT ''in utero'' causes differentiation of the penis, scrotum and prostate. In adulthood, DHT contributes to balding, prostate growth, and sebaceous gland activity. Although androgens are commonly thought of only as male Sex steroids, sex hormones, females also have them, but at lower levels: they function in libido and sexual arousal. An ...

Anabolic Steroid
Anabolic steroids, also known as anabolic-androgenic steroids (AAS), are a class of drugs that are structurally related to testosterone, the main male sex hormone, and produce effects by binding to the androgen receptor (AR). Anabolism, Anabolic Steroid, steroids have a number of medical uses, but are also used by athletes to increase muscle size, strength, and performance. Health risks can be produced by long-term use or excessive doses of AAS. These effects include harmful changes in cholesterol levels (increased low-density lipoprotein and decreased high-density lipoprotein), acne, high blood pressure, hepatotoxicity, liver damage (mainly with most oral AAS), and left ventricular hypertrophy. These risks are further increased when athletes take steroids alongside other drugs, causing significantly more damage to their bodies. The effect of anabolic steroids on the heart can cause myocardial infarction and strokes. Conditions pertaining to hormonal imbalances such as gynecomas ...

Testosterone Propionate/testosterone Phenylpropionate/testosterone Isocaproate/testosterone Decanoate
Testosterone propionate/testosterone phenylpropionate/testosterone isocaproate/testosterone decanoate (TP/TPP/TiC/TD), also known as a Sustanon 250 (Organon), is an injectable combination medication of four testosterone esters, all of which are androgens/anabolic steroids. Pharmacology The four testosterone esters are as follows; * 30 mg testosterone propionate * 60 mg testosterone phenylpropionate * 60 mg testosterone isocaproate * 100 mg testosterone decanoate Cumulatively, a 1 ml of the oil solution contains exactly 250 mg of above mentioned testosterone esters. This particular numerical value is clearly depicted in the name of the product, ''Sustanon 250''. They are provided as an oil solution and are administered by intramuscular injection. The different testosterone esters provide for different elimination half-lives in the body. Esterification of testosterone provides for a sustained but non-linear release of testosterone hormone from the injectio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Testosterone Propionate
Testosterone propionate, 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. Side effects of testosterone propionate include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire. Testosterone supplementation is also known to reduce the threshold for aggressive behavior in men. The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). It has strong androgenic effects and moderate anabolic effects, which make it useful for producing masculinization and suitable for androgen replacement therapy.

Male Contraceptive
Male contraceptives, also known as male birth control, are methods of preventing pregnancy by interrupting the function of sperm. The main forms of male Birth control, contraception available today are condoms, vasectomy, and Coitus interruptus, withdrawal, which together represented 20% of global contraceptive use in 2019. New forms of male contraception are in Clinical trial, clinical and Preclinical development, preclinical stages of research and development, but as of 2025, none have reached Approved drug, regulatory approval for widespread use. They could be available before 2030, assuming smooth development and clinical trials. These new methods include topical creams, daily pills, injections, long-acting implants, and external devices, and these products have both hormonal and non-hormonal mechanisms of action. Some of these new contraceptives could even be unisex, or usable by any person, because they could theoretically incapacitate mature sperm in the man's body before ...

Duration Of Action
Pharmacodynamics (PD) is the study of the biochemical and physiologic effects of drugs (especially pharmaceutical drugs). The effects can include those manifested within animals (including humans), microorganisms, or combinations of organisms (for example, infection). Pharmacodynamics and pharmacokinetics are the main branches of pharmacology, being itself a topic of biology interested in the study of the interactions of both endogenous and exogenous chemical substances with living organisms. In particular, pharmacodynamics is the study of how a drug affects an organism, whereas pharmacokinetics is the study of how the organism affects the drug. Both together influence dosing, benefit, and adverse effects. Pharmacodynamics is sometimes abbreviated as PD and pharmacokinetics as PK, especially in combined reference (for example, when speaking of PK/PD models). Pharmacodynamics places particular emphasis on dose–response relationships, that is, the relationships between drug con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Testosterone Enanthate
Testosterone enanthate is used in the treatment of low testosterone levels in men. It is also used in hormone therapy for women and transgender men. It is given by injection into muscle or subcutaneously usually once every one to four weeks. Side effects of testosterone enanthate include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire. The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). Testosterone enanthate is a testosterone ester and a long-lasting prodrug of testosterone in the body. Because of this, it is considered to be a natural and bioidentical form of testosterone, which make it useful for producing masculinization and suitable for androgen replacement therapy. Esterase enzymes break the ester bond in testosterone enantate, releasing free testosterone and enanthic a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
