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.
Old school bodybuilders where forced to look for extreme techniques to pump themselves up. In the movie “pumping Iron” you see how these icons pumped their muscles to the max. Their arteries thick, and bloodfilled almost bursting through their skin. Others like Larry Scott used an other princeple he called “Burns” … Before old school bodybuilders stepped on stage to be judged, Arnold reveiled he used some alcohol to look bigger and not that flat with the arteries more swollen. On certain steroids like Trenbolone and Deca Durabolin they suffered a limp dick and very often the same happened after a cycle (PCT) With VCL this is past history.
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.
Since beef is an important ingredient for most bodybuilding diets and even a lotta fastfood is consumed on the "Junk Day". we want to inform you about the quality like we did before: 
A 21-year-old man was out with friends and purchased a quantity of legal party pills identified as ’99.9%-pure DMAA’. He took the recommended dose of 2 tablets at approximately 11:30 pm along with a capsule identified as 150 mg of caffeine. He had already ingested 1 can of beer.
