A great deal of what we know about steroids is derived from competitive bodybuilding; all of it, of course not but there is a debt that is owed. Moreover, as we have discussed, what we know and understand of anabolic hormones has in many cases led to a better understanding of how our muscles work, how our hormonal structure and function is laid out and in within these understandings we have found ourselves wiser in-terms of general health and fitness. A great deal of what we see today in popular culture is owed to steroids and competitive bodybuilding and since the two go hand-in-hand many aspects of fitness can trace their roots to competitive bodybuilding.
Thanks to competitive bodybuilding we have seen an explosion of a more health and fitness aware society; the gyms where we exercise were built by competitive bodybuilders, the exercises and routines, the basic nutritional principles we understand were all first discovered and perfected by competitive bodybuilders; without them there is no fitness craze. Nevertheless, because of the negative attention they are given and the manner in-which they are often perceived, steroids have always been viewed as a major sore on the competitive sport yet without them the competitive sport would not exist as it does and we wouldn’t understand the things we do.
The truth of the matter is competitive bodybuilding represents the base and root form of many things admired in popular culture. The bigger than life action heroes of the silver screen, they owe their existence to bodybuilding; professional wrestling, how we utilize training for sports such as football and baseball, boxing and for the most part all competitive sports, they owe much of their existence in their present form to bodybuilding. The macho muscular identity many men aspire to, its roots are largely founded in bodybuilding and what’s perhaps most interesting of all is in each of these aspects steroids are a major part of the game. Our desire for things that are bigger than life, in all aspects of life, while some of them are unique unto their own many have roots that run long and deep in a connection with bodybuilding and steroids as a whole.
There are also some who complain of joint pain when using Winstrol. As a steroid that does not aromatize there will be no water retention but the “dry feeling” may not be what many think it is. Most who use the steroid will be physique athletes or gym rats during a cutting phase. They will also typically add it into a plan late in the diet once they’re already lean. Typically, when you become very lean, bodybuilding lean, this makes the joints a little uncomfortable. With or without Winstrol this discomfort could potentially exist. As for pro athletes who have nearly every last steroid at their disposal, remember, if Winstrol weren’t effective in competitive sports so many athletes wouldn’t make it a primary and favorite choice. In fact, the combo of Winstrol with low doses of Nandrolone is a very common stack among many athletes, and this stack will greatly eliminate any potential joint discomfort should it exist.
