i used it for 6 months last year to help me pass my RN fitness test as running isnt my good side of fitness.
It does give you a sugar rush and helped do a bit more whilst training, and once i passed i used it until it ran out whilst continuing my running and the odd weights here and there.
I just use maxi muscle diet shake now which is good enough for when i go running.
I wouldnt use N.O explode again purely cause the taste was vile lol.
