Score breakdown
Each dimension below is scored 0 to 100 against a fixed scale, not against the rest of the catalog, so adding a product never moves this number. The overall score is the average of the dimensions this product declares data for. How the scales are set →
49/100
Mixed
Absorption rate ?How much carbohydrate an hour the glucose-to-fructose blend can move. Scored from the stated or derived ratio (1:0.8 tops out this scale); an Estimated ratio counts the same as a Stated one here.72
Carb density ?How much fuel one sachet carries. 90 g is the ceiling here, matching the top of the range cited for multi-transportable-carb intake.33
Value (cost/gram) ?Price of one gram of carbohydrate. Not physiological: a market-based scale from 15 cents/g (0) to 2 cents/g (100).35
Gut comfort ?A proxy, not a taste or tolerance test: shorter ingredient lists score higher, from 15 ingredients (0) to 1 (100). Nobody has actually run these through anyone's gut for this score.57

What it costs you
- 2:1 is the previous generation of the ratio science.
- 10.4 cents per gram for a worse ratio.
- Sodium is not declared on the panel.
- Sold in fours rather than boxes at most retailers.

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 a plain, low-ingredient gel.
- You are fuelling at 60 g/hr or below.
- You already use their planner.
Look elsewhere if
- You are targeting 90 g/hr or above.
- You are cost sensitive.
- You need declared sodium for a hot-weather plan.
