Precision Fuel PF 90 Gel 57
Three servings of Precision's own PF 30 Gel welded into one resealable pouch, the same 2:1 blend and the same seven ingredients, at 29% less per gram ($0.074 vs $0.104) than buying it in 30 g sachets.
Score breakdown
The overall score is the average of what's below, each measured against every other gel we've reviewed.
57
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.100
Sodium ?Sodium carried by the gel itself, on a scale topping out at 1000 mg — the upper end of what's typically lost to sweat in an hour.0
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).58
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

Verdict
what it does · what it costsWhat it does well
- 90 g of carbohydrate in a single pouch, more than any other gel in this catalog carries in one package.
- Identical seven-ingredient formula to PF 30, just packaged with less wrapper per gram.
- Resealable cap lets you meter the dose across a ride instead of committing to a full sachet at once.
What it costs you
- 2:1 glucose to fructose is the same older-generation ratio as PF 30, behind the 1:0.8-class blends on sustainable intake rate.
- 0 mg of sodium, declared on the label rather than just undeclared, so it contributes nothing to your electrolyte plan.
- 36 g of sugar in one pouch is a lot to take in a single squeeze if you don't dose it in stages.

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 already use PF 30 Gel and want fewer wrappers to open and carry on long efforts.
- You want to pre-load carbohydrate for a long stretch and meter it yourself rather than count individual sachets.
Look elsewhere if
- You need declared sodium from the gel itself rather than a separate source.
- You're targeting a higher intake ceiling than a 2:1 ratio supports and want SiS Beta Fuel's or Maurten's blend instead.
