After 51 years of cycling and as the current owner of the serious 2019 Venge (bragging to establish ethos), I find this product to be the shi. Its the best one Ive found so far. Give it 5-10 to metabolize and the results are an explosive burst of energy. I swear I can hear the Hamster Dance song once it starts to kick in like a druga legal drug. I usually hit two of the gels every 45 minutes on long rides. The watermelon flavor is the best.
