Nitrates+
Customer · 3 days ago
Pros
The science behind the product makes sense and it's affordable.
Cons
Did some testing with taking Nitrates+ as described and without in comparable environments (half marathon around the airport, same pace, same weather). Felt a lot thirstier and more fatigue when consumed Nitrates+ before. Really strange. May be good for beginners but with already high VO2Max (about 60) I can't recommend it.
Goal
Improving my aerobic performance in long endurance trainings (>1,5h)
