Skratch Labs Super High-Carb Sport Drink Mix 50
Built on Cluster Dextrin, a highly-branched cyclic dextrin that carries far less sweetness than standard maltodextrin (just 4 g of sugars out of 50 g carbohydrate), mixed more concentrated than almost any other drink here, at only 8–10 fl oz of water.

Verdict
what it does · what it costsWhat it does well
- Only 4 g of sugars out of 50 g carbohydrate, one of the lowest sugar-to-carb ratios of any drink mix here.
- Mixed in just 8–10 fl oz of water, so it can be sipped concentrated rather than filling a full bottle.
- 200 mg of sodium alongside the carbohydrate.
What it costs you
- 5.2 cents a gram, mid-pack among the drink mixes here on a pure cost-per-gram basis.
- No stated glucose:fructose ratio; Cluster Dextrin is a glucose polymer and fructose makes up a small share of the formula.
- At this concentration it needs to be diluted further if you want it as your primary fluid source rather than a sipped addition.

Worth the money if
- You want low sweetness and a concentrated format you dilute to taste.
- You're stacking carbohydrate sources and want one that isn't cloying.
Look elsewhere if
- You want the lowest cost per gram of carbohydrate.
- You want a stated, verifiable glucose:fructose ratio.
