Magna Rxtra: What is the difference?
There is a great deal of confusion in the market about the intended purpose of Magna Rxtra. Magna Rxtra appears to offer the same basic ingredients as Magna Rx, and it is difficult to determine the exact purpose of the small addition of a proprietary blend halfway down the ingredients list. Some consumers believe that the proprietary blend in Magna Rxtra is meant to yield a greater penis length, while others are under the impression that this new, small addition is meant to increase energy during sex.
While the claims made on the company website are short, and sound simple, Magna Rxtra appears to support the latter claim of increased energy, although the word stamina is used consistently. So, what is stamina in terms of sex, and how can a small proprietary blend of herbs increase the stamina experienced during sex? Or, rather, is there any reason to believe that Magna Rxtra would cause any measurable change in the performance of a buyer?
Proprietary Blend Ingredients
In a smaller amount than “Asian” or “Oriental” Ginseng, these ingredients are listed as a proprietary blend in Magna Rxtra: Bitter Orange (fruit), Tribulus (aerial parts), buteus superba (Flame-of-the-Forest) (root), Cola (seed), Royal Jelly. The entire concoction is listed as 200 mg, which leaves less than 40 milligrams for each ingredient. There is no reason to conclude that the effects of these products would be cumulative, so it is assumed that this small amount would cause some immediate change in the ability to perform over a long period of time, as this is the popular understanding of sexual stamina.
While tribulus has been connected to increased testosterone production, this will have little immediate effect on sexual energy. Taking tribulus over a period of time may lead to more testosterone, but this will not necessarily lead to greater stamina, although this is the most supported ingredient. Remember that the amount of tribulus is not listed, and that many other supplements contain this ingredient. None of the others appear to have any direct connection to sexual performance, although cola seed has been shown to increase energy. At less than 40 mg, however, there is likely to be no change.
In conclusion, the difference between Magna Rx and Magna Rxtra is that Magna Rxtra contains a proprietary blend which may give Magna Rxtra a small advantage in testosterone and energy production in amounts that are unmeasurable. Magna Rxtra offers no increase in the size of the penis over the claims of Magna Rx.
