Professor Richard Hanson and his team at Case Western Reserve University in Cleveland, Ohio, thought they had embarked upon an interesting but routine experiment. They had an enzyme – PEPCK-C – that had been discovered 50 years earlier at their university. It occurs in all animals and appears mainly in their livers and kidneys where it is associated with the production of glucose. But there is also some in the muscles. Wondering what it did there, Hanson and his team decided to see what happened if they massively increased the amount of PEPCK-C in the muscles of mice.
Reports in the press last week have indicated that the famous muscle bound actor Sylvester Stallone was caught recently with a ‘personal supply’ of Chinese Jintropin, a synthesized version of Human Growth Hormone. As you may know, possession of steroids in the US regularly carries a jail term and the use of Jintropin has exploded in the country since the steroid law was tightened up as it circumvents the law by not officially being a steroid. The use of growth hormone (GH) is increasingly used by more mature trainers, who want to benefit from its rejuvenating qualities. Growth hormone is a naturally occurring hormone that support the bodies ability to increase muscle growth, recovery and aids definition. After the age of around 21 years of age, it starts to decline rapidly.
The amino acid L-arginine is most familiar today as the main active ingredient in popular food supplements designed to boost nitric oxide (NO) levels.
Elk velvet antler supplements have been used in traditional Chinese medicine for thousands of years as an aphrodisiac and as a cure for ulcers, arthritis and anemia.
Writing in Flex magazine, Jim Wright thinks that it might be “the most significant advance in Creatine supplements since Creatine monohydrate was originally introduced to the bodybuilding market.” Muscle and Fitness magazine is also optimistic, writing that it, “certainly warrants a closer look from anyone looking for a boost to his or her muscle gains.” What are they talking about?
Scientists have proved that even the most seemingly innocent chat with a woman can be enough to send male sex hormones soaring. A team from the University of Chicago paid students to come into their lab under the pretence of testing their saliva chemistry. While there, the students got to chat to a young female research assistant.
Yes! It’s even been called “irritable male syndrome”, and it might be why some men become like Alf Garnett the older they get — grumpy and irritable. It appears that men’s mood swings are down to a sudden drop in testosterone. Not only does testosterone increase muscle growth and speed up fat loss, it also appears to influence your brain, and therefore your behaviour. In fact, some scientists believe that middle-aged men go through a menopause, just like women. Dr. Lincoln, whose work is featured in New Scientist, first identified irritable male syndrome in sheep. In the autumn, rams’ testosterone levels soar and they mate. In the winter, testosterone levels fall and they lose interest in sex. He found that even though testosterone is supposed to be linked to more aggressive behaviour, the rams were more likely to injure themselves when their levels of testosterone were low. Because the human brain is loaded with testosterone receptors (the parts of the brain that respond to testosterone), your behaviour is likely to be affected if your testosterone levels drop too low. Any kind of stressful event, such as relationship problem, an argument with the boss at work — even a hard workout in the gym — could affect your testosterone levels.
