Worth every penny *by A***S on August 21, 2025* This supplement really works. You can feel the difference in about an hour. You will notice increased vascularity and better pumps when you work out. It also helped lower my BP and increased my erectile function. I recently bought some cheaper stuff and regret it. ### ⭐⭐⭐⭐ Great Stuff, Also Works Great For us Older Men for sexual health *by J***N on January 27, 2020* Well I'm over 50 so I'm not using this to work out .. the little blue pill is the same except this is increasing your ntric acid levels back to where they should be when you were younger so you function as you did younger .. oh and it's a great amino acid complex .. I'm a professional touring billiard player so I'm waking the table training about 7 hours a day and I can see the teardown in my shoulders .. ### ⭐⭐⭐⭐⭐ Worked for sure *by C***X on March 24, 2021* On cell typing so keep it short. Physical just happened to be 3 weeks after taking daily. BP 104/80. WOW. Lowest official reading I can recall. I've had top BP readings from 128-160. I've been on great diet and no alcohol recently, but see next experience. I know this has helped from a surfing experience. Started taking this and surfed a few days later. I'm in the water an hour paddling back out after a wave and think to myself... I feel so strong paddling. Just a sense of strength that was different. Later that evening it hit me that I had started taking this supp. That took away any placebo effect in my book. I also felt warmer and a few times pin priks for a few about 45 min after taking. This all seem consistent with relaxing the blood vessels and better circulation. ## Frequently Bought Together - N.O.
