ich hatte es bei mehreren Radrennen ( über 110km) konsumiert und muss sagen gefühlt hat es mich in den schwierigen Momenten gut gepusht. Mein Richtwert liegt bei einem bis zwei (je nach körperlicher Belastung) Beutel pro Stunde. Einen Stern Abzug wegen dem Geschmack, ich sag Euch der letzte Beutel im Rennen war immer eine Überwindung. Man will aber auch nicht das Risiko eingehen, auf dem letzten Kilometer einzubrechen 😅

Arrived today 23.01.25 and on the box it says expires Feb 2025. Am I supposed to consume the entire box in 8 days? This is not the first time I've seen this, I have seen quite a few SiS products reviews from other customers saying the products are either already expired or soon to be and I find this unacceptable.

High amount of carbs per gel compared to other brands and they taste good. What more could you ask for.

Tried a number of gels over the years and these are definitely the best for taste but also for that extra energy kick. I use them for Hyrox races just after burpees and every are kicked in as you go into the rower so fast acting.

Best gel for long sustained efforts. Out did every other I've tried. SIS makes great products.
