Basic about Anabolic Steroids
The history of Steroids
Anabolic steroids were developed
in the late 1930s primarily to treat hypogonadism, a condition in which
the testes do not produce sufficient testosterone for normal growth, development,
and sexual functioning.
Anabolic Steroids
These are synthetic derivatives
of testosterone; a hormone that occurs naturally in the body controlling
many functions. Among these functions is the promoting of anabolism.
Steroids mimic this natural occurring event and have the ability to
do so at an accelerated rate. Though the exact means by which steroids
exert their effects is still somewhat of a mystery, some aspects are
known for certain. Onceanabolic steroids are in the blood, they bind
to androgen receptor sites. Then they enter the cell, just like the
endogenous hormone would, and alter the function of that cell. After
changes in DNA and RNApatterns, an increased rate of protein synthesis
is observed. This increase is thought to occur simultaneous to increased
nitrogen retention by some and secondary to it by others. The important
thing is that it happens, not how it happens actually, because this
retention of nitrogen is actually a sign that muscle tissue is being
deposited.Anabolic steroids also inhibit the amount of a catabolic hormone
called cortisol that enters muscle tissue. Less of this hormone is thought
to aid in muscle growth as well. Anabolic steroids can be broken down
into two classifications; anabolic and androgenic. The type and concentration
of androgen receptors found within an organ or tissue determine to what
degree it is effected by the anabolic or the androgenic features. Since
anabolic steroids are not totally separated between the two, both are
felt to some degree when any steroid is used.Testosterone is a "male"
hormone, because it is responsible for developing some of the male characteristics
such as lowering of the voice and hair growth, and because the male
body produces much more of it than the female.Testosterone in the male
is produced mainly in the testis, a small amount being produced in the
adrenal. It is synthesized from cholesterol. The regulation of its production
may be simplified thus: the hypothalamus (part of the brain) produces
gonadotrophin releasing hormone (GnRH) which acts on the anterior pituitary
to increase the production of luteinizing hormone (LH) and follicle
stimulating hormone (FSH). LH acts on the Leydig cells in the testis,
causing them to produce testosterone. FSH, together with testosterone
act on the Sertoli cells in the testis to regulate the production and
maturation of spermatozoa. Testosterone in turn acts on the hypothalamus
and anterior pituitary to suppress the production of GnRH, FSHand LH,
producing a negative-feedback mechanism which keeps everything well-regulated.
The small amount produced in the adrenal (in both sexes) is regulated
by secretion of adrenal corticotrophin hormone (ACTH), also secreted
by the pituitary.Testosterone, and its metabolites such as dihydrotestosterone,
act in many parts of the body, producing the secondary sexual characteristics
often male: balding, facial and body hair, deep voice, greater muscle
bulk, thicker skin, and genital maturity. At puberty it produces acne,
the growth spurt and the enlargement of the penis and testes as well
as causing the fusion of the epiphyses (through its conversion to estrogens),
bringing growth in height to an end. It plays some role in maintaining
the sexual organs in the adult, but only a low concentration is required
for this.The normal production of testosterone in the adult male is
4 to 9mg per day. The normal plasma concentration is 22.5nmol/l, of
which 97% is protein bound. Most is excreted in the urine as 17-keto
steroids, but a small amount is converted to estrogen's. It would be
great if steroids only exerted their effect on muscles but unfortunately,
they effect many other parts of the body as well. This is why gains
in muscularity are accompanied by side effects.
The legal use of steroids
Steroids are used for treating
anemia, because of it's ability to increase the production of red blood
corpuscles (red blood cells). They are also used for treatment of leukemia,
cancer mammae, and at times steroids are also used for general strengthening
therapy. Steroids have also been tried in combination with other drugs
as a means of helping AIDS patients.
Oral vs. injectable
Injectable steroids are
longer lasting in the body, but therefore they can be detected in your
body for a longer period of time, so athletes that are likely to be
doping tested have shifted from using injectables to orals.
The problem with orals however,
aside from the fact that they are not as long lasting, is that they
put a lot of strain on the liver as they must be processed there. Larger
quantities are also needed as a lot of it is broken down before it enters
the bloodstream.
Facts
1 Fact: 40% substances sold as anabolic steroids are diluted, contaminated, or simply fake.
2 Fact:Anabolic steroids are synthetic
substances related to the male sex hormones, called androgens. Doses
taken by abusers can be up to10- 50 times greater than doses used for
treating medical conditions!
3 Fact: Under Federal law it is illegal to possess or distribute anabolic steroids
for non-medical uses. However, heavy demand has generated a black market
with estimated sales of up to $900 million a year!
4 Fact: The overwhelming majority of
black market anabolic steroids contain little or no active ingredients
at all. Many of them are counterfeit or completely fake altogether.
