Without a doubt the product does what it says. I have noticed less fatigue during rides and recovery. Minimal soreness and more energy to push through hills and rides in general. I'm a believer and a definite return customer. Read more

My regular workouts have been tougher than usual in the past few months. I have a blood disorder where I make less hemoglobin. I enjoyed my workouts more after taking Niagen - better motivation, attitude, alertness - but, attributed the physical struggle to aging (46) and my blood disorder. After taking this for 3 days, my run time was one of my better times (no PR), but, I was able to power up hills rather than slow to a crawl. Niagen makes me feel great, more motivated, more "awake", but, this has given me the ability to dig deep and get through my workouts and activities without feeling as tired and worn down. I was cleaning my house yesterday until 11 p.m. after a full day of work, like I did when I was in my 20s, then went to bed and was asleep by 11:30 p.m. and woke up feeling great. I am not sure how much of a factor my blood disorder is, but I know before EPO Boost, I couldn't exercise as often as my peers, required a longer recovery time, and did not obtain gains as quickly as they do. I am happy with this product at this point - product information and reviews indicate results after 2-4 weeks. I am very excited going forward to see if there are other improvements. I can't imagine that this is a placebo effect. I have taken other supplements that did not work for me. SAVE YOUR BOTTLES - manufacturer claims if after 90 days when taken as directed (3 bottles) if not satisfied, they will refund your money. This stuff isn't cheap! Depending on your physiology, this may or may not work for you. UPDATE 5/15/18 After using this for almost 2 months, I can only say, WOW! Today, I ran 5 miles after work. Prior to taking this, I would not have done much afterwards. Today, I mowed the lawn, weeded, and cooked dinner. I am surprised by how much more I can accomplish by taking this. I don't feel drained by 5pm like I used to. My times on my runs are a bit better, but, I run more frequently and the runs seem to take less effort. Read more
