The average person thinks of the damage of aging as an inevitable process of wear and tear. However, if wear and tear were the primary cause of aging in humans, a 60 year-old should have only twice the signs of aging as a 30 year-old.
Why do most 30-year-olds show few effects of aging, while the effects of aging are so obvious in a 60 year-old person? If wear and tear were the major cause of aging, a 90-year-old person would only have 3 times as much aging damage as a 30-year-old.
At the age of 30, people have spent most of their lives with fairly high levels of human growth hormone (HGH). HGH is responsible for growth during childhood -- and for the repair and regeneration of human tissue throughout our lives. By the time we reach the age of 30, our HGH levels are only about 20 percent of their peak levels during childhood, and after the age of 30, they continue to decline at about 12 to 15 percent per decade, and often much more. By the time most of us are 30 years old, our bodies no longer produce enough HGH to repair all of the damage that is occurring in our bodies. As our HGH levels continue to decline, the damage that we call aging continues to accelerate.
The decline in HGH is not the only cause of the manifestations of aging. Even if our HGH levels remained at the level of a 25 year-old, we would continue to experience the effects of aging, but those effects would be greatly reduced until we reached a very advanced age. HGH does not affect the root cause of aging, as measured by maximum lifespan, but it can certainly affect many of the manifestations of aging.
By increasing the levels of HGH in our bodies, we can slow, or even reverse, many of the manifestations of aging. It must be done carefully, though, and under medical supervision. Ideally, this HGH replacement should begin at about the age of 30 years, but HGH replacement can be beneficial at any age above 30. In fact, for older people, HGH therapy can reverse the manifestations of aging by 5 to 15 years or more. There is no other single therapy currently available that can have the impact on the aging body that HGH can have.
On the left you see a picture of ampoulle made by Newgenpharm, Korea. Its an obvious fake, seen the doses.

Numerous studies have indicated that weight training exercises that recruit large muscle masses (i.e. the compound exercises) result in the largest anabolic hormonal response by the body. The proportions of anabolic hormones (mainly growth hormone and testosterone) secreted are thought to be functions of factors such as total muscle mass recuited, exercise intensity, rep count and rest between sets - with lower rep sets and longer breaks between them favoring testosterone release and higher rep sets and shorter breaks between them favoring growth hormone (hGH). The more total muscle mass involved, the higher the hormone levels rise. For this reason, Squats will cause a greater hormonal response than Bench Presses.
Just after the second world war a hopeful world produced a large new generation. Most of them did well. They have worked their whole life and are willing to pay for pharmaceutical aids that will prolong and ease their “golden years”. They want to grow old, but they want to grow old gracefully, maintaining their youthful skills. They don’t want to spent their last years in a wheelchair or in a nursing bed with a bedpan. They want to remain mobile and have a healthy sexlife. The success of Phizers Viagra proves that. 
by declining levels of essential hormones in the body such as sex hormones and growth hormone stops them from carrying out everyday tasks and increases the riskof falling and breaking bones that are brittle because of osteoporosis. This is not only a major socio-economic as well as a major medical and financial problem, it is also important to improve the overall well-being of all these elderly. All this led to increased funds and need for scientific research towards prevention of age related diseases. We already knew that the exogenous administration of rhGH and sex-hormones such as Testosterone (HRT) could improve overall well-being in elderly.
He put smiles on millions of faces when he helped invent Viagra. Now the brains behind the little blue pills claims to have done it again.
Half the world was in mortal terror of him. He had a sixty inch chest, twenty three inch arms, and when the Anadrol and Bolasterone backed up in his bloodstream, his eyes went as red as the laser scope on an Uzi. He threw people through windows, and chased them madly down Hempstead Turnpike when they had the temerity to cut him off. And in the gym he owned in Farmingdale, the notorious Mr America’s, if he caught you looking at him while he trained, you generally woke up bleeding on the pavement outside. Half out of his mind on androgens and horse steroids; he had this idea that being looked at robbed him of energy, energy that he needed to leg press two thousand pounds.
Body building has come a long way since the day an immortal bully kicked sand into the face of Charles Atlas. Consider Arnold Schwarzenegger. At 6'2" and 240 pounds, he boasts a 57-inch chest, a 31-inch waist and 22-inch biceps. For six years running, he was voted Mr. Olympia, the supreme title in Professional body building. Now, at the age of 29, Schwarzenegger wants to become a movie star—a superstar, to be precise. He has already appeared in two movies: "Stay Hungry," an underrated Bob Rafelson film that starred Sally Field, and "Pumping Iron," a semidocumentary about the 1975 Mr. Olympia contest, which was Schwarzenegger's final championship. He made the film to dispel the talk of homosexuality, steroids and obsessive narcissism that comes up whenever body building is mentioned. Most critics liked the movie, some didn't, but on one point all the critics agree: Bodybuilders may come and go, but there is only one Arnold.
I'll post here an old article (2009) from "The New York Times"
I want to catagorise some known and unknown influencing factors on the half-life and potency of injected steroids.
