Nitraflex Overall Review: 3 out of 5.

German American Technologies Nitraflex is considered a PWO, or pre-workout mix. This particular brand emphasizes the importance of testosterone boosting, although it offers some vasodilators in the mix as well. The predominant ingredient in this product is called calcium fructopyranose borate (CFB). Boron was once popularly used when working out because it was believed to boost testosterone, but  opinions on certain scientific evidence made it go out of style. New research suggests that boron can in fact help boost testosterone levels.

Calcium fructopyranose borate can be summed up in simple terms; it increases testosterone levels by inhibiting processes that break it down. It has been scientifically backed that while taking this supplement, within 6 days testosterone levels may be raised significantly. A person can benefit from this because testosterone is the building block of muscle. As a bonus, it can add stamina and performance during sexual activity.

Boosting testosterone could be a good thing, but there are some potential risks. When feeding ourselves additional testosterone (more than the body already produces), the body may become dependent on this level of hormone. As a result, when discontinuing the product, decreased sex drive and ability to build muscle may be hindered. Aggressive behavior and anxiety may be side effects as well.

When training, take 1 scoop of Nitraflex 30 minutes prior to working out. On off days, take one scoop in the morning. Mix scoops with 8 fl oz of water. Do not exceed one serving in the same 24-hours period.
