The study, called Testosterone in Older Men or TOM, did show improved strength in men who used the testosterone gel for three to six months – bringing their hormone levels to the normal range for young men. Compared to the placebo group, they were able to leg-press and chest-press more weight, and climb more stairs while carrying a load. Scientists have halted a federally financed study designed to see if testosterone supplements improve muscle strength in older men. Twenty-two percent of men who used a daily skin gel suffered cardiovascular problems, compared with five percent who got a placebo – a fourfold greater risk. Finally, through science, we now have a better understanding of the side effects of some of the best testosterone boosters.
Nonetheless, science confirms that the levels of testosterone declines as one advances in age. Science also agrees that these boosters contain vital natural elements which are always deficient in the body but are necessary for the The other known side effects of using testosterone boosters include increased frequency of urination, breast enlargement, decreased sperm count, fluid retention, and increased aggressive behaviors.
