mechanisms of action of steroids

How anabolic steroids promote muscle growth and recovery.


Endogenous androgens are responsible for the growth and development of the sexual organs in men and the maintenance of secondary sexual characteristics. Endogenous anabolic steroids such as testosterone and dihydrotestosterone and synthetic anabolic steroids mediate their effects by binding to and activating androgen receptors. In skeletal muscle, anabolic steroids regulate the transcription of target genes that control the accumulation of DNA in skeletal muscle necessary for muscle growth.[4][5][3]

Anabolic steroids also upregulate and increase the number of androgen receptors, thereby enabling increased training intensity and indirectly helping to increase muscle size and strength. They also have a stimulating effect on the brain through their various effects on various central nervous system neurotransmitters, antagonism of glucocorticoids, and stimulation of the growth hormone-insulin-like growth factor-1 axis.

Nandrolone decanoate and nandrolone phenpropionate are associated with an increased ratio of anabolic to androgenic activity. Nandrolone decanoate is a slow-acting anabolic steroid designed for the sole purpose of increasing muscle mass. It works by promoting nitrogen retention in muscles, leading to an increase in muscle size and relieving joint pain by promoting collagen synthesis and improving bone mineralization. Nandrolone phenpropionate also causes increased muscle growth, appetite stimulation, and increased red blood cell production.

Dromostanolone is a synthetic anabolic steroid with anti-estrogenic properties and is five times more potent than methyltestosterone, widely used by bodybuilders to prepare for competition. It increases the retention of nitrogen, phosphorus and potassium, leading to increased protein anabolism and decreased amino acid catabolism, leading to increased muscle density and hardness.

Administration


Administration of anabolic steroids can be done via oral pills, injections, topical creams or gels, and skin patches.

-Testosterone cypionate is administered at 50 to 400 mg intramuscularly once to 4 times per month for primary hypogonadism and hypogonadotropic hypogonadism.
-Administration of testosterone undecanoate begins with an initial dose of 750 mg, then 750 mg four weeks after the first dose, and 750 mg thereafter, administered ten weeks apart between each dose.
-Testosterone gel is administered at 11 mg 3 times daily, with a total dose of 33 mg per day.
-Transdermal testosterone is applied at a rate of 50 mg once a day in the morning to the upper limb, shoulder or abdomen with a maximum dose of 100 mg per day.
Another testosterone gel is administered at a dose of 40 mg once a day every morning with a maximum dose of 70 milligrams per day.

Drugs not approved by the FDA for medical use

-The dosage of Nandrolone Decanoate is 100 mg per week for comfort and relief from joint pain and in the dose range of 200 mg to 400 mg per week to increase growth and performance. It is ideally used for around ten to twelve weeks to achieve the desired results in athletes, weightlifters and bodybuilders.
-Dromostanolone is available in the form of 200 to 400 mg per week, which bodybuilders use to improve their athletic performance. Due to its short half-life, dromostanolone injections are administered every 3 to 4 days.

The role of corticosteroids in reducing inflammation and suppressing the immune system.
When prescribed in certain doses, corticosteroids help reduce inflammation. This can relieve symptoms of inflammatory conditions, such as arthritis, asthma, and skin rashes.

Corticosteroids also suppress the immune system. This can help control conditions in which the immune system mistakenly attacks its own tissues.

How are corticosteroids used?
Corticosteroid medications are used to treat rheumatoid arthritis, inflammatory bowel disease (IBD), asthma, allergies, and many other conditions. They are also used to prevent organ rejection in transplant recipients. They do this by helping to suppress the immune system. Corticosteroids also treat Addison’s disease. This is a rare disease that occurs when the adrenal glands do not produce enough corticosteroids that the body needs.

Corticosteroids are administered in different ways, depending on the condition being treated:

-Through the mouth. Tablets, capsules or syrups help treat inflammation and pain associated with certain chronic diseases, such as rheumatoid arthritis and lupus.
-By inhaler and intranasal spray. These forms help control inflammation associated with asthma and nasal allergies.
In the form of eye drops. This form helps treat swelling after eye surgery.
-Topically. Creams and ointments can help cure many skin conditions.
-By injection. This form is often used to treat muscle and joint symptoms, such as pain and inflammation from tendonitis.
