Creatine and Androstenedione: Myth vs. Reality
What if there was a drug you could take that guaranteed increased energy and strength? Not only that, but it came in an easy-to-swallow capsule, it could safely and naturally increase your level of testosterone, (the most potent of muscle building hormones), and it would be perfectly legal to buy and relatively inexpensive.
The sellers of creatine and androstenedione (pronounced androe-steen-die-own) make these sorts of claims although there are no long-term studies of the effectiveness or safety of these drugs. Nevertheless, retailers can’t keep them on the shelves. Their popularity has been aided by high profile athletes. Both drugs are chemicals naturally produced in the body and found in minute amounts in food, mostly red meat. But that is where the similarities end.
Creatine
For many years, the world’s foremost studies of creatine and its effect on athletic performance were carried out in secrecy by communist Eastern-bloc countries. But after the fall of Communism, the training and experimental drugs used on Soviet and East German Olympic athletes was revealed. Aside from exposing the truth about illegal anabolic steroid use, there was the discovery of a "vitamin" called creatine, which was quickly introduced to the U.S. and marketed as an ergogenic, or energy-enhancing supplement.
Creatine was not a vitamin, however, but a synthesized blend of certain amino acids, which are the building blocks of proteins. The benefit creatine provides is increased energy for quick, anaerobic bursts of activity, such as are required in weightlifting. Athletes taking creatine can do more repetitions and sets of exercises than they could without it. Essentially, it speeds up the process of adding strength and size to the muscles by intensifying the workout. It has been compared to the way a marathon runner might saturate his muscles with carbohydrates before a race to provide endurance except that creatine strictly helps in anaerobic activities like muscle contractions.
Creatine is made in small amounts by the body, and aids a substance called adenosine triphosphate (ATP), which controls all types of muscle contractions, from bench pressing 400 pounds to blinking an eye. To contract a muscle, the ATP molecule releases one of the three phosphate groups. Creatine comes into play by attaching to the free-floating phosphate and reforming into ATP. Thus, energy is provided until the creatine in the muscle is depleted. Thus, the effect of a creatine supplement is to provide the muscles with more creatine than the body can produce on its own and thus increase energy.
The Gentileschi—both father and little girl—delivered more expressive works of art than did Caravaggio. Fusing the cool blues, yellows, and violets that were strikingly truant from Caravaggio's palette, their sketches, especially those of Orazio, regularly reflected neighborhood impacts. By and by—and critical to the dialog of Caravaggism in Europe—their work uncovers an ingestion of Caravaggio's tenebrism, as well as of his way to deal with religious
Creatine is an effective, powerhouse nutrient that is derived from the amino acids glycine, L-arginine, and L-methionine. Creatine is beneficial for athletes as it helps improve strength, muscle mass, body composition, and boosts athletic performance. Research has shown improvements in endurance, power, and performance; this is all due to the creatine increasing phosphocreatine (PCr) within the muscle, which allows for quicker regeneration of the body’s energy.
Creatine serves as an energy reserve in muscle cells. Muscular contraction is powered by the breakdown of ATP (adenosine triphosphate) to ADP (adenosinediphosphate). When all the ATP is broken down, creatine phosphate in the muscle donates a phosphate group to ADP, and further energy reactions can occur. Creatine monohydrate is a precursor to creatine phosphate. By supplementing with CM, CP levels in muscle apparently are maximized, and more muscular work can occur, since there are greater energy reserves to use.
To conclude, Creatine or “Nature’s Steroid”, is an over the counter dietary supplement that helps build lean muscle mass, and shortens recovery time between workouts. Its side effects are nowhere near life threatening, and the supplement is natural and already in our muscles. Creatine is a legal, healthy way to enhance muscular strength and endurance in the striving athletes of the world.

Lorenzo De Medici can be considered as one of the most influential men of the 13th century. His work in political affairs and administration were renowned in all Italy and his family could count on him in every aspect. Lorenzo was also a promoter of a new period called Renaissance. He was one of the first “mecenate” to explore this new way of art. In this project, I will concentrate how he developed art in Florence, giving a clear example through an Artist of that period that was working for him: Sandro Botticelli. His work “The Spring” is a well-defined example of what we can call “art in the Renaissance”, in particular for the Italian Renaissance.
Seeking a greater athletic physique and ability, athletes turned to the use of steroids. Once the dangers and possible health risks arose, athletes then turned to performance enhancers. Two specific supplements have taken the sports world by storm and are now being used by athletes of all ages. They are androstenedione and creatine. It took years for people to begin to understand how dangerous steroids really are.
The High Renaissance (1490-1527) was a period of Italian painting that had the qualities of harmony and balance with dignified, calm movement. It was also a time when painterly techniques of linear perspective, vanishing points, shading (chiaroscuro and sfumato) and other methods of realism were mastered. There were significant changes in the development of early sixteenth century Venetian paintings, in particular, Titian’s paintings during the High Renaissance. I’ve chosen Gallery 607 at the Metropolitan Museum of Art because it has the works of Titian, who was one of the greatest Venetian artists, well known for his remarkable use of color and for his appealing renderings of the human form. Titian created rich, luminous images by layering
Anabolic Steroids or simply put, “Steroids”, is a medicine which has become increasingly popular in the last few decades, specifically in the world of professional sports and body building. In a literal term, the word anabolic means building of the body muscle and by using anabolic steroids, the potential user becomes stronger, sharper, larger and tougher than he would normally be. The consequences of these steroids could be much bigger to a human body and the usage of such illegal products could put an individual’s body at great risk (Haupt & Rovere, 1983).

Athletes are always searching for ways to enhance their performance. Recently, beginning in the 1950s, that search has included the use of illegal substances like steroids and growth hormones. Illegal substances have been used widely by athletes in hop es of achieving the desired Olympic gold medal or multi-million dollar contract. Some nations, for example the late East Germany in the 1970s and 1980s, have mandated the use of steroids by their athletes. The downside of using those illegal substances is that because they are illegal, getting caught using them can lead to losing that coveted gold medal, a lifetime ban from sports, and a total loss of honor and dignity. This is why the search is now on to find some legal means of enhancing athletic per formance.
The objective of this essay is to provide an explanation of Leonardo da Vinci’s life and work as an artist in context with his time spent in Milan. Following an initial introduction to Leonardo’s formative years in Florence (and his apprenticeship to the sculptor and painter Andrea del Verrocchio, 1435-88), I will attempt to explain the significance of his presence in Milan with detailed descriptions of his work there. Giorgio Vasari (1511-74) was also an artist and architect, but is perhaps better known for his book on the lives of well known painters, sculptors and architects (published 1550; from Cimbue to his autobiography which was included in a revised edition):
Doping is a practice that has been going on since the time of "ancient Greek athletes, who supposedly ate herbs, sesame seeds, dried figs, and mushrooms for this purpose" (Hoberman, 1992, 104). Likewise, athletes have readily consumed such drugs as caffeine and alcohol to improve performa...
... Critics note that the stories were initially passed on by a precursor, Solon (638–558 b.c.e.), a government official and writer who voyaged broadly. Critias and Solon were both predecessors of Plato.
