Best carb supplement
I take this pre/post workout. I can train longer when I take it preworkout. I think this is better then cluster dextrin, I try that but didn’t have energy like with kabylon. When I got the product it was full to the top. Plus the scooper was on top too so it was easy to dig out. You get your moneys worth, each serving is 50g of carbs.

Upon opening this bottle, the first thing I noticed is the texture, it reminded me of a finely ground instant mash potatoes so I was slightly worried about how it would mix. Turns out it mixes really well with cold water and a shaker cup and isn't chalky of gummy at all. I do notice it works best to mix and drink vs pre-mixing the night before and leaving it in the fridge for a morning workout. I got the Lemon Ice flavor and its very good and refreshing.
I highly recommend adding this to your routine and your "must have on hand" supplement cabinet it is the real deal.

Superior product that provides excellent performance advantages
Reviewed in the United States on June 12, 2023
I love this product. I have so much energy when I load with this before my workouts. I use it in several different aspects. I use this for long weightlifting workouts and before I take an Army Physical Fitness Test. It provides me with just enough more energy in the tank to destroy my 2-mile run and pass all the younger soldiers by on the last 1/2 mile. I also love it for my PM workouts along with a non-stimulant pre-workout after a long day at work. This product helps me pull the tail end of my workout off with a bang instead of barely getting through it and by not having to have a caffeine pumped pre-workout I can still get to bed and sleep well.Reviewed in the United States on June 12, 2023

I used a scale and just shy of 1/4 cup is just over half a serving. So, if you didn't get a scooper anywhere in the tub, just use 1/4 cup or 1/2 cup depending if going for a full 200cal/50carb serving or half of that.
Now, does this stuff work? I normally do 30-50 mins on the bike/rowing machine alternating days twice a day. Decided to do 2hrs of rowing this morning fasted at first. Had about half a large gatorade I sipped on half way through till the end. Felt weak and light headed. Decided to down a half a serving of this before I started to make my oatmeal to get some calories in fast. Worked great. Within 8 minutes I felt fine. Didn't wolf down my oatmeal or anything. Ate it casually. Feel absolutely great 3 hours later. Might do a 20-30min short session tonight rather than just the big workout this morning.
Flavor is very strong, but its fine if you are going to be sipping on this while doing longer distance bike/rowing or whatever sessions. I think mixed with a decent sized water bottle or 2 depending on how much water you need would make this stuff highly recommended. Rather strong if you wait until post workout and try to down this stuff. And that's with me trying to down half a serving this morning quickly. Can't imagine a full serving. Maybe you have an ultimate sweet tooth though :P (Rainbow Candy tastes like the powder from "Fun Dip" if you ever had that stuff. Where you dip the white sugar stick into the powder and suck on it. Very 'Sugary' tasting)

1/2 cup serving if you don't have a scooper. Works Well!
Reviewed in the United States on May 9, 2021
This thing came full to the brim! I had to dump out half of it into a ziploc to try and find the scooper. There wasn't one... Thankfully I keep old ones from other tubs of supplements. I found a 60cc one that is just about perfectly half a serving(1 serving it says is 2 scoops).Reviewed in the United States on May 9, 2021
