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 far more concentrated than any other drink here, at only 8–10 fl oz of water.
Score breakdown
The overall score is the average of what's below, each measured against every other drink mix we've reviewed.
50
Mixed
Based on 3 of 4 measures ?A dimension a product doesn't declare is left out of its average rather than counted against it -- so this score reflects fewer measures than a product with a full panel.
Carb density ?How much fuel one scoop or sachet carries. 90 g is the ceiling here, matching the top of the range cited for multi-transportable-carb intake.56
Sodium ?Sodium carried by the mix itself, on a scale topping out at 1000 mg — the upper end of what's typically lost to sweat in an hour.20
Value (cost/gram) ?Price of one gram of carbohydrate. Not physiological -- a market-based scale from $0.15/g (0) to $0.02/g (100).75

Verdict
what it does · what it costsWhat it does well
- Only 4 g of sugars out of 50 g carbohydrate, the lowest sugar-to-carb ratio 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
- $0.052 a gram, the second-most expensive drink mix 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.

Who this is for
the numbers, appliedThe field tells you what it is. This is who should act on it.
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.
