Researchers from the Food and Nutrition Department at Seoul National University examined the effect of fish oils on muscle recovery in rats.
The rats were assigned like so:

The rats were immobilized for a few weeks and after the immobilization they were allowed to exercise their muscles. When a person is immobilized for certain reasons as fractures etc. the muscle that isn`t used anymore is going to atrophy, and in our case with these rats, the scientists are interested in the fastest way to rejuvenate and repair that muscle with a low degree of inhibition.

When the rat is allowed to exercise, the muscle has tension placed on it again and the researchers can examine the degree of inhibition in muscle recovery.

In the article i saw some scientific details but this is what you need to know in large about this experiment; the findings (in rats) indicate that dietary fish oil inhibits the early stage of muscle recovery by suppressing the activation of anabolic pathway Akt–p70s6k signaling and prostaglandins synthesis.

Muscle Atrophy
Muscle atrophy as i`ve said earlier, appears when you disuse your muscles and it`s followed by loss of mass and strength. For example if you have a hand in a cast you force your muscles from the hand to limit their movement so the atrophy appears because the muscle is no longer needed for the daily routine of grabbing, eating, washing etc..

There are many diseases and conditions which cause atrophy of muscle mass except that lack of exercise, diseases like AIDS or cancer that are notable for the severe muscle atrophy seen in their process called cachexia.

Another disease that causes muscle mass atrophy is sarcopenia. This muscle atrophy disease is known through elders because as you age, you have a gradual decrease in the ability to maintain skeletal
muscle function and mass and that`s because the satellite cells which help to regenerate skeletal muscle fibers have a gradual failure, or a decrease in sensitivity of the critical secreted growth factors which are necessary to maintain muscle mass.

Treatment for Muscle Atrophy
Some of the treatments are common among us like exercising with progressive weight to rehabilitate your muscle mass and strength.
Other treatments for muscle atrophy includes the use of functional electrical stimulation to stimulate the muscles and it has seen some succes through paraplegic pacients, or amino acid therapy for regenerating damaged or atrophied muscle tissue.

Holly Van Remmen from the University of Texas Health Science Center (USA) is currently researching an experiment on mice modified to prevent them from having a protective antioxidant. As a result of the lacking antioxidant, the mice lose muscle mass and function at a much faster rate than normal mice.
Holly Van Remmen hopes to find alternative treatments for muscle atrophy and halt the process of sarcopenia.

Stunted growth

Male Side Effects

Prostate Problems: Some AAS convert to Dihydrotestosterone or variants of that hormone, and can enlarge the prostate causing problems urinating or even prostate cancer.
Testicular atrophy: Since AAS mimic the male hormone testosterone, the testicles can shrink as a result of their no longer being needed to produce the hormone.
Gynecomastia: This female-like breast tissue development in males is caused when steroids aromatize, or convert into high levels of estrogen .
Sexual Dysfunction: Some steroids can cause sexual dysfunction and temporary impotence.
Reduced reproductive function: AAS can cause a reduction in sperm count, resulting in decreased ability to reproduce.
Male Pattern Baldness: The genetically patterned loss of hair on the scalp caused by the AAS conversion into Dihydrotestosterone or its variants.

Female Side Effects

Facial and Body hair increases
Thinning of the hair on the scalp
Deepening of the voice
Clitoral Hypertrophy (an increase in the size of the clitoris)
Menstrual cycle irregularity (leading to decreased reproductive function)

Adolescent Side Effects

Although any of the general side effects, and gender specific side effects can also happen in adolescents, there are also some side effects which their undeveloped bodies are more susceptible to.
Certain AAS can stunt growth by prematurely stopping the lengthening of bone tissue and fusing growth plates. This causes a decrease in overall height, as total height potential goes unreached.
An increased rate of bodily maturation. The final adult bodyweight and overall size can be achieved though the user is still too young.
There is an increased risk of psychological problems due to the underdevelopment of various parts of the brain.

1.Legitimate Medical Use

Testosterone is used to treat low levels of naturally-occurring testosterone in males as detected by medical professionals. It can also be prescribed to cancer and HIV patients.

2.Side Effects

Liver toxicity and high blood pressure are two of the most serious side
effects. Acne, water retention, development of breast tissue in men as well as the development of male characteristics in women are potential side effects.

3.Warning signs requiring medical attention

Yellowing of the skin and/or eyes is a sign of liver toxicity. In addition,
those experiencing abdominal pain, dizziness, vomiting or shortness of breath should contact a medical professional.
