SiS GO Isotonic Energy Variety Pack

I bought these gels initially because I discovered about the "Wall" you get in marathon/training running. Around Mile 15 one day, I noticed I was getting tired quickly, and within half a mile I could not even jog, and had to sit down every minute or two of walking. A quick google search explained that I ran out of carbohydrates for energy, and my body initiated the backup (and incredibly inefficient) process of converting fat to energy. So doing some research around Energy Gels, I found out it's quite the complicated process. You need to consider the fact that during marathon's your stomach's blood supply is lessened as your body redirects more blood towards your legs. Therefore not using water (for most) or using too much can led to GI side effects or the embarrassment and awful sensation of vomiting. So after discovering this Gel company, and the fact that they're formulated so you don't need water to chug these down with, I gave the variety pack a go with training. Now I think all energy Gels flavors are not ideal, but honestly these are fine and all I need to have is something that I can not think about it. And I found the tropical one to be the "best". The last thing I need during my marathon is to consume something disgusting 3 times an hour for a few hours. So as long as it's satisfactory, like some of these were, then it's good with me. Anyways, these proved to work! I bought a box of 30 Tropical (as well as their sodium and some caffeine ones) and have used them every weekend for a few weeks now. I did a 20 mile run consuming 3 per hour per the instructions, which led me to complete my distance without any energy issues! No "wall"! These also rip fairly easily at the perforation, I had no issues with opening them during the runs. The only real issues I had with them is their size and price. It was decently larger than I thought at 6in by 2in wide, but I guess that's what 2oz gets you. A pack of 6 variety was $10, and a pack of 30 Tropical flavor was around $30, so in bulk it's a dollar a piece. I'm no expert in this field, and that may be a great deal for all I know, so take those negative opinions with a grain of salt from this newbie marathon runner. Aside from that, gonna stick with these for the long run (I promise that pun was not intentional hahaha). I will be taking them alongside me for the upcoming marathon! That alone should prove their efficacy, and hopefully your decision if you were as lost as I was in this world of energy gels. --- Update: Ran the LA Marathon, carried these for a packet per 20 minutes. I had ZERO energy issues throughout the race. Sure I was tired, but I had no carbohydrate energy issues. These were also gently on my stomach with how sensitive it was that day. Strongly recommended!

Muy buenos! Si nunca los has usado, recuerda mantenerte hidratado

While the product is good, this has an expiry date of Aug 2021 ie less than 4 months left. Seller should have indicated so.

Purchased in Mid February, expires in March. Do not buy this product.

Llego a buen tiempo y la fecha de caducidad era extensa, faltaba mucho porque me daba miedo por otros comentarios pero nada que ver
