What's in it
What's in MNSTRY? Gel 40 and Power Carb HEAT, honestly
MNSTRY is a German direct-to-consumer endurance brand, and its whole thing is transparency. Most companies bury the carb ratio in a spec sheet. MNSTRY puts it in the product name: "Gel 40 (1:0.8)", "Power Carb HEAT (1:0.8)". You know the glucose:fructose split before you read a single label.
That sounds like a small detail. It isn't. The ratio is the part of a fuel that decides how many grams per hour your gut can absorb, and almost nobody states it upfront.

The 1:0.8 ratio, and why it is in the name
Your gut absorbs glucose and fructose through separate transporters. Lean only on glucose and you hit a ceiling near 60 g/h (Jeukendrup). The split currently considered optimal for high rates is about 1:0.8 glucose:fructose at 90 g/h and up (Hearris 2022); below that, around 60 to 90 g/h, 2:1 is the more common target. MNSTRY builds both products at 1:0.8, a deliberate bet on the high-rate end. More on the ratio.
Gel 40: double the carbs, fewer sachets
A typical gel holds 20 to 25 g of carbs. The Gel 40 holds 40 g, maltodextrin plus fructose at 1:0.8. The practical win is sachet count: hitting 80 g/h takes two of these an hour instead of three or more on standard gels. Fewer wrappers, less to track.
Power Carb HEAT: high sodium for hot days
The Power Carb HEAT drink mix is 80 g of carbs at 1:0.8, with high sodium (MNSTRY states about 400 mg; some panels imply more). "HEAT" is the higher-sodium hot-weather variant. Sodium need is personal, so treat 400 mg as a starting point, not a prescription.
Make your own MNSTRY
A 1:0.8 maltodextrin and fructose blend is one of the easier mixes to replicate, since both products use the same two bulk ingredients. The advantage of mixing your own isn't only cost: you can tune the ratio toward 2:1 if you fuel at lower rates, and dial sodium up or down per session instead of a fixed 400 mg. The calculator gives you the exact grams.
Frequently asked
What is MNSTRY Gel 40?
A 60 ml energy gel with 40 g of carbohydrate from maltodextrin and fructose at a 1:0.8 ratio, with about 52 mg sodium. The "40" is the carb count, roughly double a standard gel.
What does the 1:0.8 mean?
It is the glucose:fructose ratio: for every 1 part glucose-type carb (maltodextrin), there is 0.8 parts fructose. That split is the current optimum for high carb rates, 90 g/h and up (Hearris 2022), because glucose and fructose use separate transporters.
Is a 40 g gel too concentrated?
Not as a gel. Gels are eaten, not sipped like a drink, so concentration matters less than in a bottle. The thing to watch is taking 40 g at once when your gut isn't trained for it. Sip water alongside and build the rate over time.
Can you make your own MNSTRY gel?
Yes. It is maltodextrin and fructose at 1:0.8, which you can buy in bulk and weigh out. The calculator gives you the grams to match 40 g of carbs, and you can tune the ratio and sodium to your session.
