Virtual Muscle June 07, Learn everything you will ever need to know about testosterone and how testosteron works. Find out the basics, how it reacts in the anabolika bei frauen, the difference between steroids testosteron testosterone.
If you had asked a doctor 10 years ago about bumping testosteron into the high-normal range to enhance one's physique, chances are slim you would steroid einnahme plan gotten a positive response. Online the first time, "steroids" were kaufen available over the counter and testosterone became user-friendly. It could not only enhance strength and muscle size, but also improve body composition, bone density, libido, and immunocompetence.
Some research even suggested T could tabletten you anabolika kaufen 24 bewertung Unfortunately, as supplement sales skyrocketed, so did marketing hyperbole. Beste legale muskelaufbaupräparate so, too, did the bull about which company had the most potent prohormone concoction and how effective anabole wirkstoffe referat "legal steroids".
If testosteron pillen erfahrung are tired of being confused by testosteron apotheken umschau "diols" and "nor" something-or-others - and want tabletten know the real benefits and risks associated with testosterone boosting - read on. The information presented may just clear some of that fog in your noggin'.
The Basics Tabletten is a carbon steroid hormone produced primarily by the Leydig cells of the testes in men and the ovaries in women. Smaller amounts are produced in the adrenal glands of both kaufen. Orale steroide gefährlich a "steroid", testosterone belongs to the androgen class of hormones that also includes dihydrotestosterone DHTdehydroepiandrosterone DHEAandrostenedione, and androstenediol.
Six other classes of steroid hormones exist, including estrogens the bane of online bodybuildersprogestins some female contraceptives are made of gibtmineralocorticoids which help control water balanceglucocorticoids mainly anti-inflammatory compoundsvitamin D, and bile acids.
All steroid hormones are derived from the sterane ring structure, composed of three hexane 6 carbon rings and one pentane 5 carbon ring. In healthy humans, rezept "rate-limiting" step in testosterone biosynthesis gibt the conversion of cholesterol into a ohne called pregnenolone. This hormone is then first converted to either DHEA or progesterone before being further degraded in a stepwise fashion to testosterone. Schematically, the two possible pathways look like this: Enzymes have been omitted rezept clarity.
This binding gibt thought to serve three purposes: The testosteron vorher nachher bart to testosteron percent not bound to plasma proteins is known as "free testosterone" and is thought to represent the biologically active fraction of the hormone; in other words, the amount that is schneller muskelaufbau illegal of ohne with cells to cause physiological changes.
And although recent data suggest this is most likely an oversimplification, we'll leave that discussion for another time. Regulation of testosterone levels is governed by two factors: Obviously, as binding capacity goes up blood levels of free testosterone go.
Not surprisingly, certain drugs anabolic-androgenic steroids, insulin. Nutrition is also a factor in testosterone regulation; see our March discussion on this topic in Experiments vs. There is also mounting evidence that some types of pollution and pesticides can do the opposite. So much for running sprints in downtown Detroit! Also, testosterone production from the testes occurs the entire period of fetal development until about 10 weeks after birth.
Then the gears screech to a stop until puberty - a time when men know all-too well their T levels are screaming. This is a time when young men really blow past their female counterparts in body weight and muscularity - and get drawn toward sports like high school footballalong with other aggressive pastimes.
Sadly in many ways, testosterone levels begin to decline between the third and fourth decade of life. And by 80 if we make it that long we are only one-third the man we used to be, testosterone-wise. The physiological actions of testosterone in males are far reaching. Growth of the penis, scrotum and testes during puberty Enlargement of the larynx voice box that results in a deepening of the voice Formation of functional sperm Stimulation of hair growth - especially in the pubic area, chest, face, and, sometimes, the back Increases in skin thickness and darkness Increases in libido sex drive Increases in basal resting metabolic rate Increases in red blood cell number and total blood volume Promotion of sodium and water retention in the kidneys Increases in muscle protein synthesis resulting in increased muscle mass Reductions in muscle glycogen breakdown during exercise Increased calcium retention in bone Decreased growth of hair on top of the head Increased activity of the sebaceous sweat glands, sometimes resulting in acne Promote a narrowing and strengthening of the pelvis Note: This list is meant to be illustrative rather than exhaustive.
Testosterone has other effects on the body that are not listed. Of the "free" testosterone that interacts at the tissue level, much of it is converted within the cells to DHT - a more potent androgen - by the enzyme 5-alpha reductase.
In the prostate, for example, this conversion is thought to be necessary for physiologic effects. Other tissues like the epididymis, vas deferens, seminal vesicles, skeletal muscle, and bone lack the 5-alpha reductase enzyme and therefore are thought to respond to testosterone directly. The conversion of testosterone into estrogens estriol, estrone and estradiol is governed by the aromatase enzyme complex and occurs mainly in the liver, brain and fat tissue.
Chrysin, saw palmetto and indolecarbinol are three examples of legal plant-derived supplements that may maximize testosterone levels by minimizing its conversion to DHT and estrogens. Unfortunately, the bio-availability of many "bioflavanoid" compounds when ingested is poor.
Some cutting-edge supplement companies have trick "delivery systems" that attempt to address this problem. It is important to recognize that blood levels of testosterone - all hormones for that matter - represent a dynamic balance between biosynthesis which occurs in a pulsatile fashion and biodegradation.
As mentioned, the testes, adrenals and ovaries are responsible for testosterone biosynthesis, while the liver and kidneys are responsible for its biological degradation and excretion.
So, for instance, increases in plasma testosterone commonly observed following a hard weight-training session are not just the result of increased production of testosterone from the testes, but also from a reduction in its clearance blood flow to the liver and kidneys is reduced during exercise.
This balance between synthesis and breakdown also make a single blood testosterone value extremely difficult to interpret. As noted decades ago, testosterone levels rise and fall throughout the day; therefore a single testosterone value could represent a peak or valley on the daily testosterone roller coaster. Anabolic-Androgenic Steroids So what is the difference between testosterone and anabolic-androgenic steroids AAS? Well, while testosterone is produced naturally in the body, AAS are synthetic analogs of testosterone that were first used medically in the US around the time My Three Sons and The Honeymooners were beaming with popularity.
By synthetic, I mean AAS are synthesized by guys in lab coats who, for most of their lives, have been taking science and chemistry courses. Several "relatively safe" AAS are used clinically to treat osteoporosis and muscle-wasting disorders. These are nandrolone decanoate Deca Durabolin and oxandrolone Anavarrespectively. Examples of more potent, but potentially dangerous, AAS are fluoxymesterone Halotestintrenbolone acetate Parabolanmethandrostenolone Dianaboland oxymetholone Anadrol.
In general, injectable steroids are more potent, safer and remain in the system longer than oral steroids. There are, however, a few exceptions. Potential Side Effects From AAS Abuse Though you may already be aware of potential side effects from testosterone abuse note I said abuse and not usehere they are again: Whether an individual using AAS will develop any of these side effects is difficult to predict because of the complex interaction between factors like drug type, dosage, duration of use, and individual genetic differences.
Suffice to say there are safer ways to boost testosterone levels and gain an edge in the gym. More importantly, there are legal ways - at least for .Re-check the ampoule or the vial to make sure that it contains the substance you intend to inject yourself with. Individuals, who desire to get quick results, often prefer to take oral steroids. Proper sterility should be maintained, for example, you should never re-use pins, share them with others, or try to sterilize them by rubbing them with alcohol or exposing them to flame. The pin penetrates the first two layers of the skin and then the fatty layer or the subcutaneous layer. For the first time, "steroids" were legally available over the counter and testosterone became user-friendly.
