Testosterone boosters used in testosterone replacement therapy come in several different forms, but all of them possess the increased risks of severe side effects, according to an article published in the Huffington Post. Forms of testosterone boosters include skin patches, gels, sticks (similar to deodorants), injections, pills and mouth patches.
Testosterone booster drugs to treat low testosterone have skyrocketed in sales over the past 10 years, becoming a multi-billion dollar industry. In 2013, an estimated 1.5 million men were taking testosterone replacement therapy, more than double the number in 2010.
Much of that growth is attributed to a focused advertising effort by low testosterone product manufacturers who target middle-aged men. Advertisements will often present symptoms of low testosterone that can also be attributed to normal aging, such as fatigue and low libido.
Testosterone booster use has been associated with an increased risk of severe side effects, including heart attack and stroke, regardless of the way a patient takes testosterone. Doctors urge patients to get clinically tested for low testosterone before receiving any testosterone boosters to avoid the potential for serious testosterone therapy side effects.
