A: People assume that older men are still fertile since they can produce sperm. Theoretically you can have children at any age if you have sperm. But is that sperm going to give you the same genetic qualities as the sperm from a younger individual? We know that fertility does decline. We know that after the age of 30, there is a drop in testosterone of 1 percent a year. Testosterone is the energy, the hormone that you need to make good-quality sperm. It takes much longer for an older man to have children. But we haven’t studied fertility of men in their 60s or older.

In November 1942, the Italian cyclist Fausto Coppi took "seven packets of amphetamine" to beat the world hour record on the track. [25] In 1960, the Danish rider Knud Enemark Jensen collapsed during the 100 km team time trial at the Olympic Games in Rome and died later in hospital. The autopsy showed he had taken amphetamine and another drug, Ronicol , which dilates the blood vessels. The chairman of the Dutch cycling federation, Piet van Dijk, said of Rome that "dope – whole cartloads – [were] used in such royal quantities." [26]

Anabolic steroids are synthetic versions of hormones that human body produces naturally. Their main role is to assure increased physical performance in all sports and athletic pursuits. Steroidal compounds enhance stamina, strength, weight and size of muscles and may improve the energy levels during physical training. Oral and injectable steroids posses the ability to increase athletic performance, have a positive effect on red blood cells production and bones density. The steroids are used in accordance with requirement and needs of any athlete individually. There are special compounds which are not suitable for women and a series of anti-estrogen products which main role is to counter the eventual side effects of steroids use and to restore natural testosterone levels of the human body. These compounds nowadays became an important part of muscle building process among professional athletes and bodybuilders, as well as regular people, males and females that have the goal to become more attractive and exhibit good looks.

Acetyl L-Carnitine ((R)-3-Acetyloxy-4-trimethylammonio-butanoate) and commonly abbreviated as ALCAR) is an acetylated form of the compound L-Carnitine. Unlike Carnitine, Acetyl L-Carnitine is able to cross the blood-brain barrier. Once it reaches the brain, it is converted into Acetyl-COA, which binds with choline already present to become acetylcholine. Acetylcholine is a neurotransmitter closely tied to many important cognitive functions, such as the formation of memory, reasoning skills, processing of perceptual data, and the ability of neural structures to grow.
