Chronic Cardio Energy Pack

This is our recipe. The whole thing. Three ingredients, a scale, fifteen minutes. We publish this because we have to — if we won't tell you what's in our pack and how to make it, we haven't earned the right to sell it to you.

Honey230 gAny real honey. Raw, filtered, wildflower, clover — doesn't matter much.
Tapioca syrup32 gDE42 grade ideally. Substitute brown rice syrup 1:1.

Step-by-step instructions
  1. Warm the honey. Bowl over warm water (40–50°C / 105–120°F) or briefly in the microwave. Warm, not hot. Honey above ~60°C starts losing enzymes and developing bitter notes.
  2. Dissolve the salt into the honey first. Stir until you don't see any grains. If you skip this step, you'll get gritty packs.
  3. Add the tapioca syrup. Stir until the mixture looks uniform — no streaks, no separation.
  4. Portion it. ~26 g per portion into reusable silicone flasks, mylar pouches with a heat sealer, or small zip bags.
  5. Use within 4 weeks at room temperature in a sealed container. Refrigerate for longer storage.
Why this formulation works

Honey's natural sugar profile is close to the research-optimal 0.73:1 fructose:glucose ratio (at the intestinal wall after hydrolysis) on its own. The tapioca syrup nudges it the last few points by adding glucose-pathway sugars. The salt drives absorption via the sodium-dependent SGLT1 transporter and replaces electrolytes.

Why you might still buy ours

At ~$1.50 per sachet, you're paying for consistency (every pouch identical), packaging (heat-sealed, won't leak in your vest), ingredient verification (we test every honey batch for adulteration, glyphosate, and antibiotics), and not having to do this. If those things aren't worth the markup, make it yourself. That's the point.

GU Energy Gel DIY Version

Tri-Berry • 32g serving • ~91 kcal • 23g carbs • 7g sugar • 55mg Na • ~$0.15
+

Based on: GU Energy Gel (Tri-Berry)

GU's formula is maltodextrin + fructose for dual-transporter absorption, plus BCAAs and green tea caffeine (20mg). The commercial product has 18 ingredients. This DIY version hits the macros with 5.

Ingredients

IngredientAmountRole
Maltodextrin powder16.8 gPrimary carb (fast-absorbing glucose polymer)
Fructose powder7.0 gActivates GLUT5 transport pathway
Water8.0 gHydration + viscosity control
Sea salt0.14 g~55mg sodium
Xanthan gum0.2 gThickener (mimics commercial gellan gum body)

Optional: a few drops of natural berry flavoring for taste authenticity.

Instructions

  1. Measure all ingredients by weight on a digital kitchen scale.
  2. Combine maltodextrin and fructose powder in a small bowl. Stir dry until uniform.
  3. Add water one teaspoon at a time, stirring after each addition. The maltodextrin will absorb water and form a thick, sticky paste.
  4. Add the sea salt. Stir to dissolve completely.
  5. Add xanthan gum and stir vigorously for 30–60 seconds until fully incorporated — the mixture will thicken noticeably.
  6. Add flavoring drops if using, then stir again.
  7. Transfer to a reusable gel flask or squeeze packet using a small spatula.

Consistency: Thick and sticky — not pourable liquid, not stiff paste. Should flow slowly when tilted, like cold honey. Storage: Refrigerated up to 2 weeks. Room temp during activity: same day. Omitted: BCAAs (L-Leucine, L-Valine, L-Isoleucine) — research on BCAAs in gels during exercise is thin. Caffeine (20mg from green tea extract) — add 0.5g instant espresso powder if desired.

SiS GO Isotonic DIY Version

Lemon Lime • 60ml serving • ~88 kcal • 22g carbs • 0g sugar • ~12mg Na • ~$0.20
+

Based on: SiS GO Isotonic Energy Gel

The world's first isotonic gel — ~38g carbs per 100ml matches blood plasma osmolality, so it empties from the stomach as fast as water. No water chase needed. Commercial version uses maltodextrin (33%), gellan gum, xanthan gum, and acesulfame K (artificial sweetener).

Ingredients

IngredientAmountRole
Maltodextrin powder23.0 g~99% of carbs
Water37.0 mlIsotonic dilution (essential — this ratio is the point)
Sea salt0.03 gTrace — barely a grain (~12mg sodium)
Xanthan gum0.3 gGel body (prevents it being pure liquid)

Optional: a tiny drop of stevia for sweetness without calories (SiS uses Acesulfame K).

Instructions

  1. Warm the water to about 40°C (104°F) — slightly warm to touch. This helps maltodextrin dissolve without lumps.
  2. Slowly pour maltodextrin into the warm water while whisking continuously. Add gradually over 30–45 seconds.
  3. Add the trace of sea salt and stir.
  4. Sprinkle xanthan gum over the surface and whisk vigorously for 60 seconds. It will thicken slightly.
  5. Allow to cool to room temperature before transferring to a 60ml soft flask.
  6. Consistency check: When squeezed from a flask, the gel should flow freely in about 1 second without squeezing hard. If it needs real pressure, add 2–3ml more water.

Consistency: The thinnest gel in this collection — intentionally. Should feel like drinking a slightly viscous liquid. Storage: Refrigerated up to 10 days. Stir/shake before use. Key: The isotonic property depends on the high water ratio (~38g carbs/100ml). Less water makes it hypertonic and requires a water chase.

Honey Stinger DIY Version

Gold (Classic) • 34g serving • ~110 kcal • 26g carbs • 25g sugar • 45mg Na • ~$0.35
+

Based on: Honey Stinger Classic Energy Gel (Gold)

The Gold is Honey Stinger's flagship — honey is the first ingredient, fortified with B vitamins and potassium citrate. 34g serving, not 31g as some older sources report. Ingredient list: Honey, Water, Potassium Citrate, Salt, Niacinamide (B3), Calcium Pantothenate (B5), Pyridoxine HCl (B6), Riboflavin (B2), Thiamine Mononitrate (B1), Cyanocobalamin (B12).

Ingredients

IngredientAmountRole
Honey32.0 gPrimary carb — natural glucose/fructose (~1.1:1 ratio)
Water1.5 gThins honey for flask-squeezing ease
Sea salt0.12 g~46mg sodium

Optional: crush one B-complex vitamin tablet and stir in to replicate the B vitamin fortification. Add a pinch of potassium citrate (food grade) for potassium.

Instructions

  1. Measure honey by weight on a scale. Do not estimate — a tablespoon of honey varies widely.
  2. Gently warm the honey (30 seconds in a warm water bath or 10–15 seconds in microwave) until it flows easily.
  3. Add water and sea salt while honey is still warm. Stir until salt is fully dissolved (~30 seconds).
  4. If adding a B-complex tablet, crush to powder before stirring in.
  5. Allow to cool slightly, then transfer to a squeeze flask.

Maurten Gel 100 DIY Version

Unflavored • 40g serving • ~95 kcal • 25g carbs • 25g sugar • 20mg Na • ~$0.40
+

Based on: Maurten Gel 100

Maurten's hydrogel technology: sodium alginate + gluconic acid + calcium carbonate form a gel matrix in stomach acid that encapsulates carbohydrates for faster gastric emptying. 6 total ingredients. Fructose:glucose ratio is 0.8:1. This is the most technically demanding recipe in this collection.

Ingredients

IngredientAmountRole
Glucose / dextrose powder13.9 gPrimary carb (SGLT1 pathway)
Fructose powder11.1 gSecondary carb (GLUT5 pathway). 0.8:1 ratio.
Sodium alginate (food grade)0.5 gHydrogel matrix former. Available on Amazon (~$8, lasts 100+ servings).
Calcium carbonate (food grade)0.3 gTriggers gelation by cross-linking alginate
Water14.0 mlDissolves all ingredients

Note: Maurten's label shows 20mg sodium (down from older reports of 85mg). The sodium comes primarily from the sodium alginate (~52mg) — no added sea salt needed. Gluconic acid from the commercial formula is omitted; it assists gelation but isn't critical for a home version.

Instructions

  1. Add 14ml water to a small bowl.
  2. Sprinkle sodium alginate over the surface and whisk vigorously for 2 full minutes. Alginate takes time to hydrate and will clump if rushed.
  3. Let the alginate solution rest 3–5 minutes to fully hydrate.
  4. Add glucose and fructose powders. Stir until dissolved (~60 seconds).
  5. Last step: Add calcium carbonate. Stir gently but thoroughly. Calcium ions will cross-link the alginate, initiating gelation. Texture shifts from liquid to soft gel within 1–2 minutes.
  6. Allow to set undisturbed for 5 minutes. Result should be a firm, wobbly gel — like very soft gelatin.
  7. Transfer to a squeeze packet. The gel breaks up when squeezed and re-forms slightly.

Consistency: A firm, wobbly soft-gel mass — not a liquid. When squeezed, it breaks into a flowing semi-liquid. The unusual texture is correct. Storage: Best consumed fresh within 24 hours. Hydrogel weakens and releases water over time. Refrigerate if storing; knead before use. Do not freeze. Sodium note: Our recipe yields ~52mg Na from the alginate. Maurten's label says 20mg — they may use a lower-sodium alginate grade or a different Na measurement methodology.

Huma Chia DIY Version

Strawberry • 43g serving • ~94 kcal • 22g carbs • 14g sugar • 105mg Na • ~$0.35
+

Based on: Huma Chia Energy Gel (Strawberry)

Real fruit base with powdered chia seeds. No maltodextrin — uses brown rice syrup (glucose) + cane sugar (sucrose) + fruit fructose. Commercial ingredients: Strawberry Puree, Cane Sugar, Water, Brown Rice Syrup, Powdered Chia Seeds, Strawberry Concentrate, Sea Salt, Citric Acid.

Ingredients

IngredientAmountRole
Strawberry puree15.0 gFlavor base + natural carbs
Cane sugar9.0 gPrimary added sugar
Brown rice syrup14.0 gComplex carb + body/thickness
Ground chia seeds (finely milled)2.0 gFiber, texture. Must be finely ground — whole seeds clog flasks.
Water2.0 gConsistency adjustment
Sea salt0.27 g~105mg sodium

Optional: a few drops of strawberry concentrate or citric acid for brightness.

Instructions

  1. Grind chia seeds in a spice/coffee grinder until a fine powder forms.
  2. Combine strawberry puree, cane sugar, and brown rice syrup in a small bowl. Stir until sugar dissolves (~2 minutes). Warm briefly if the rice syrup is stiff.
  3. Add water and sea salt. Stir thoroughly.
  4. Sprinkle ground chia powder over the mixture and whisk in immediately before it clumps.
  5. Transfer to a gel flask and seal.
  6. Refrigerate for 30 minutes before use — chia absorbs water and thickens the gel to correct consistency.

Based on: Spring Energy Canaberry

Real-food gel — no maltodextrin, no rice syrup. Commercial ingredients: Basmati Rice, Organic Banana, Strawberry, Maple Syrup, Coconut Water, Coconut Oil, Soy Lecithin, Organic Lemon Juice, Guarana, Vitamin C, Citric Acid. Lower carb count (17g) than most gels — some energy comes from fat (3g from coconut oil).

Ingredients

Omitted from commercial version: soy lecithin (emulsifier — not needed at home scale), guarana (negligible caffeine in Canaberry), vitamin C, citric acid.

Instructions

  1. Cook basmati rice per package instructions. Spread on a plate to cool completely (at least 30 minutes). Warm rice does not blend smoothly.
  2. Melt coconut oil if solid (10 seconds in warm water bath).
  3. Combine cooled rice, banana, strawberry, maple syrup, lemon juice, and coconut oil in a high-powered blender.
  4. Add sea salt.
  5. Blend on high for 90–120 seconds until smoothest possible puree. Some texture will remain — this is authentic to Spring Energy. Add 1–2ml water if blender struggles.
  6. Load into a wide-bore squeeze pouch — standard narrow-bore flasks will clog.
  7. Refrigerate immediately.

UCAN Edge DIY Version

Orange Mango • 53g serving • ~74 kcal • 18g carbs • 0g sugar • 50mg Na • ~$0.20
+

Based on: UCAN Edge Energy Gel

Important: Waxy maize starch is NOT equivalent to UCAN's LIVSTEADY. LIVSTEADY is a hydrothermally processed, high-molecular-weight corn starch (MW 500,000–700,000 Da) engineered for slow glucose release. This cannot be replicated at home. Waxy maize releases glucose significantly faster. This is a lower-cost, zero-sugar gel approximation, not a true LIVSTEADY replacement. If slow-release properties are medically important to you (e.g., diabetic athlete), use the commercial product.

Commercial ingredients: Water, LIVSTEADY Non-GMO Corn Starch, Allulose, Glycerin, Natural Flavors, Cellulose Gum, Xanthan Gum, Ascorbic Acid, Lactic Acid, Fumaric Acid, Potassium Sorbate.

Ingredients

IngredientAmountRole

Instructions

  1. Heat water to ~60°C (140°F) — hot but not boiling.
  2. Slowly whisk waxy maize starch into warm water, adding gradually to prevent clumps.
  3. Continue stirring over low heat for 2–3 minutes until thickened and slightly translucent.
  4. Remove from heat. Add sea salt and optional xanthan gum; stir thoroughly.
  5. Cool completely to room temperature before loading into a flask. Starch gel thickens further as it cools.
