Glandular nutritional supplements have been labelled a complete “waste of money” by a former American football player and founder of British nutritional company, Predator Nutrition.
Reggie Johal, who used to represent Great Britain at the sport, has suggested glandular supplements such as Boron are “bogus”, saying that they “have no effect whatsoever on testosterone levels”.
Nutritional supplements have risen greatly in popularity over recent years, tempting not only bodybuilders but also fitness fanatics and amateur athletes due to their apparent ability to increase muscle bulk.
However, Johal said that some of these supplements – such as Boron and others obtained from bull testicles – have been proven completely ineffectual.
“Boron started to appear in supplements in the 80s and 90s, and there
are still a number of products claiming that it can increase the levels of
testosterone in the blood and thus aid a harder workout,” he said.
“These claims are bogus. Recent scientific studies involving male weight
trainers have shown that Boron has no effect whatsoever on testosterone
“The only situation in which a Boron supplement would be helpful is if a person had a deficiency of the mineral. Otherwise, it’s a sheer waste of money.”
Johal suggested that reliance on substances acquired from bull testicles is completely outdated and based upon a false premise.
“Extracts such as dried bulls testicles were probably the first testosterone boosters marketed to athletes, on the basis that bulls produce a vast amount of testosterone and if we could ingest their glandular extracts, we too could grow to superhuman proportions,” he said.
“Sadly, apart from getting strange looks from people, these extracts are
worthless and better left on the bull. Thankfully (for the bulls’ sakes)
they are absent from the bodybuilding market today, although still marketed
to the impressionable and the uninformed. The reality is that there has never been a single study conducted showing benefits with the use of glandular-based products.”
