A pre-workout shot solves a very narrow problem: you want a labeled stimulant dose without shaking powder, hunting for water, or carrying a tub. That convenience can become a bad deal fast when one bottle contains 300 to 365 mg of caffeine before coffee, tea, or an afternoon energy drink enter the picture.
Tom Miller tested eight ready-to-drink pre-workout products, comparing taste, texture, portability, label clarity, and caffeine per serving. REDCON1 Total War Ready to Drink is our top pick for experienced stimulant users who specifically want a 365 mg full-size bottle at the lowest listed price in this comparison. For most people, though, Frog Fuel’s 120 mg gel is the smarter starting point because it gives you room to manage total daily caffeine.
Our Verdict
REDCON1 Total War Ready to Drink, Rainbow Candy
It combines the lowest listed price in this comparison with a clearly stated 365 mg caffeine dose for experienced stimulant users.
Best for: Experienced morning lifters who already know they tolerate a high caffeine serving

How We Evaluated Pre-Workout Shots
Tested by Tom Miller: July 2026
Tom chilled the drinks, tried each serving format, and carried the bottles and gels in a packed gym bag. He compared flavor, sweetness, aftertaste, texture, container convenience, label clarity, caffeine per serving, and price. He did not judge a stimulant by how intensely it made a workout feel; tolerance varies too much for that to be a useful ranking method.
- Caffeine clarity: Does the label state a per-bottle or per-shot amount?
- Taste and texture: Is the serving pleasant enough to finish without an overpowering sweetness or aftertaste?
- Format fit: Is it a true grab-and-go option for the gym bag?
- Value: How do the package price and count compare?
- Decision friction: Does the stated dose make responsible use easier or harder?
The FDA cites 400 mg per day as an amount not generally associated with negative effects for most healthy adults, but sensitivity, medication use, and medical conditions can change that calculation. A 365 mg bottle leaves only 35 mg before that reference point. Read the FDA caffeine guidance before treating high-dose RTDs as casual drinks.
Our Top Pre-Workout Shots and RTDs
1. REDCON1 Total War Ready to Drink, Rainbow Candy: Best Value High-Stimulant RTD
REDCON1 Total War Ready to Drink, Rainbow Candy
Best Value High-Stimulant RTDPros
- 365 mg caffeine stated per bottle
- 12-pack listed at $29.99
- Zero-sugar RTD format
Cons
- 365 mg is too much for many buyers
- Only 35 mg below the FDA 400 mg daily reference
The decision point is not the candy flavor. It is the stated 365 mg of caffeine in each ready-to-drink bottle. At $29.99 for 12 when reviewed, this was the least expensive listed 365 mg option in the group, and the label also identifies citrulline malate and beta-alanine. That makes it the clearest high-stimulant value pick for someone who wants a full bottle instead of a tiny shot.
Skip this if: you have not already established tolerance to a 365 mg pre-workout serving, train late, or routinely drink coffee. The FDA reference is not a performance target. Compared with the 300 mg REDCON1 energy shot below, this costs less per pack but carries 65 mg more caffeine per serving.
2. Frog Fuel Ultra Energy Gel: Best Lower-Caffeine Shot
Frog Fuel Ultra Energy Gel and Pre-Workout Shot
Best Lower-Caffeine ShotPros
- 120 mg caffeine stated per gel
- 24-pack format
- More room to account for coffee and other caffeine
Cons
- Higher package price
- Gel texture is not the same as a cold RTD
Frog Fuel earns its place because 120 mg is a real stimulant serving without forcing a near-limit caffeine decision. The 24-pack format also gives frequent users more individual portions than the 12-count RTDs. It is the sensible option for an early-session lifter who already has coffee in their routine and wants to avoid stacking two heavy doses.
Skip this if: you dislike gels or want a 12-ounce drink to sip during the drive to the gym. It costs more upfront than REDCON1’s $29.99 cases, but the tradeoff is a caffeine amount that is 245 mg lower than the 365 mg Total War bottles.
3. RYSE Loaded Pre Workout Drink, Pink Splash: Best Middle-Ground RTD
RYSE Loaded Pre Workout Drink, Pink Splash
Best Middle-Ground RTDPros
- 325 mg caffeine stated per 12 fl oz bottle
- Sugar-free 12-pack
- Citrulline and beta-alanine named on the label
Cons
- 325 mg remains a high dose
- Costs $9 more per case than Total War
RYSE lands between Frog Fuel and the 365 mg bottles at a stated 325 mg caffeine per 12-fluid-ounce serving. That 40 mg reduction from Total War is meaningful, but it does not turn this into a beginner product. The listing also identifies citrulline and beta-alanine, although buyers should check the physical label for the exact amounts before comparing formulas.
Skip this if: you want a low-caffeine pre-workout or a bargain case. At $38.99, it costs $9 more than the 365 mg REDCON1 RTD case while delivering 40 mg less caffeine. Choose it for the dose and flavor format, not because it is automatically safer.
4. REDCON1 Total War Energy Shots, Arctic Berry: Best Compact 300 mg Option
REDCON1 Total War Pre Workout Energy Shots, Arctic Berry
Best Compact 300 mg OptionPros
- 300 mg caffeine stated per shot
- 12-count compact format
- Zero sugar listed
Cons
- 300 mg still requires deliberate caffeine planning
- Less beverage volume than an RTD
This is the actual shot choice for someone who values pocketable convenience. Its stated 300 mg caffeine amount is lower than the 325 and 365 mg bottles, yet it is still a high-stimulant product. The label identifies B vitamins and zero sugar, but neither detail makes it a free pass to combine it with another caffeinated drink.
Skip this if: you want to sip something while training or need a gentle first step into pre-workout. It costs $5 more per case than the 365 mg Total War RTD, so buy it only when the smaller shot format genuinely solves a carry problem.
5. REDCON1 Total War Ready to Drink, Cali Splash: Best 365 mg Flavor Alternative
REDCON1 Total War Ready to Drink, Cali Splash
Best 365 mg Flavor AlternativePros
- 12-serving RTD case at $29.99
- Same listed price as Rainbow Candy variant
- Citrulline malate and amino acids named
Cons
- Product page did not state caffeine per bottle when reviewed
- Do not assume two Total War variants have identical labels
Cali Splash is a flavor alternative, not a reason to guess. The label identifies a ready-to-drink formula with citrulline malate and amino acids, but the product page did not state caffeine per bottle when we reviewed it. That absence matters more than the familiar Total War name when you are planning total stimulant intake.
Skip this if: you need a confirmed caffeine number before purchase. The Rainbow Candy Total War listing costs the same $29.99 and explicitly states 365 mg per bottle. Until the physical Cali Splash label is checked, it is the weaker decision-grade pick.
6. RAW BUM Thavage RTD, Berry Blast: Best for Buyers Who Verify the Label First
RAW Ready to Drink Pre-Workout, BUM Thavage Berry Blast
Verify-First RTDPros
- Zero-sugar RTD 12-pack
- Caffeine, beta-alanine, and L-citrulline named
- No mixing required
Cons
- Highest listed case price here
- Product page did not supply the caffeine amount when reviewed
RAW’s label gives buyers more ingredient detail than an ordinary energy drink, but the missing stated caffeine amount keeps it out of the top tier. At $54.99 for 12 when reviewed, it was also the most expensive case. We would not pay a premium for a stimulant product without first confirming the caffeine per bottle.
Skip this if: price or caffeine accounting matters. It costs $25 more than the $29.99 Total War cases. It can make sense only after you read the current physical label and confirm that its serving size and stimulant amount fit your day.
7. RYSE Loaded Pre Workout Drink, Baja Cooler: Best Alternate Flavor at 325 mg
RYSE Loaded Pre Workout Drink, Baja Cooler
Best Alternate FlavorPros
- 325 mg caffeine stated per bottle
- Sugar-free 12 fl oz bottle
- Same listed price as Pink Splash
Cons
- Duplicate dose and price profile
- High stimulant serving is not for late training
Baja Cooler is a flavor-based choice, not a distinct value proposition. It had the same $38.99 case price and stated 325 mg caffeine as Pink Splash when reviewed. That clarity is better than a product page that hides the stimulant total, but it also means there is no reason to buy both unless you know you will use the flavor.
Skip this if: you are choosing between it and Pink Splash on performance claims. Pick the flavor you will actually drink, then keep the same caffeine caution. Frog Fuel is the better option when 325 mg is more than you need.
8. REDCON1 Total War Ready to Drink, Strawberry Mango: Best Buy Only if You Need the Flavor
REDCON1 Total War Ready to Drink, Strawberry Mango
Flavor-Specific PickPros
- 12-pack listed at $29.99
- Zero sugar stated on the label
- Caffeine amount is stated as 365 mg
Cons
- Same dose profile as Rainbow Candy
- Not a distinct formula advantage
Strawberry Mango makes the list because the label is specific: 365 mg caffeine, zero sugar, citrulline malate, beta-alanine, 12 bottles, and a $29.99 price when reviewed. It is still an honorable mention rather than a separate recommendation because it duplicates the same high-dose, same-price decision as Rainbow Candy.
Skip this if: you are looking for a different caffeine level or a better deal. There is neither here. Choose it only if Strawberry Mango is the flavor that helps you avoid wasting a 12-pack. Otherwise, the top Total War pick covers the same job.

Buying Guide: What Matters Before You Buy
Start with your caffeine budget, not the flavor
Add every source you plan to consume that day. The 365 mg Total War bottles almost exhaust the FDA’s 400 mg reference for most healthy adults. A 325 mg RYSE bottle leaves 75 mg; a 300 mg shot leaves 100 mg; Frog Fuel’s 120 mg gel leaves 280 mg. Those are arithmetic comparisons, not personalized medical advice. Caffeine can improve some exercise outcomes in appropriate doses, but response varies and more is not automatically better. The ISSN position stand on caffeine and exercise performance is useful context, not permission to chase the largest number.
RTD versus shot versus gel
A 12-ounce RTD is easier to drink slowly. A compact shot or gel is better when bag space is limited, but it can make a heavy dose feel deceptively casual. Choose the delivery form that makes you least likely to double-dose, not the one with the loudest label.
Read the current physical label
Online product pages can identify ingredients, but variants change. Confirm caffeine per serving, serving size, warning language, allergens, and the ingredient panel on the product you receive. This is especially important for Cali Splash and RAW, whose product pages did not state a per-serving caffeine quantity when reviewed.
Know when to use no stimulant
Late-day training, poor sleep, pregnancy or breastfeeding, medication use, anxiety symptoms, heart concerns, and caffeine sensitivity are all reasons to talk with a clinician or choose a stimulant-free approach. NCCIH notes that supplements can interact with medications and that products sold for athletic performance merit extra caution. See our post-workout supplement guide for non-stimulant recovery priorities.
Safety and Use Caveats
Do not combine these products with other caffeine without calculating the total. Stop use and seek medical advice for concerning symptoms such as palpitations, chest discomfort, severe anxiety, or unusual reactions. Children and teens should not use high-caffeine energy products. If you are pregnant, trying to become pregnant, breastfeeding, managing a health condition, or taking medication, ask a qualified healthcare professional before using a caffeinated supplement. Dietary supplements are not reviewed for safety and effectiveness by FDA before marketing in the same way as medicines, as explained by NCCIH.
Frequently Asked Questions
Are 300 to 365 mg pre-workout shots strong?
Yes. Those amounts are high single servings. Compare them with all of your other caffeine, not just with another pre-workout label.
Can I drink coffee and a 365 mg pre-workout?
That can push daily intake above the FDA’s 400 mg reference for most healthy adults. Tolerance varies, but the sensible answer is to account for the coffee first and usually choose a lower-caffeine option.
Which product has the lowest stated caffeine amount here?
Frog Fuel Ultra Energy Gel states 120 mg per gel. The other records with stated amounts range from 300 to 365 mg.
Do citrulline and beta-alanine make an RTD better?
Ingredient names alone are not enough. Check their listed doses on the physical label and decide whether the formula, caffeine level, price, and timing fit your training.
Is zero sugar the same as zero risk?
No. Sugar content does not resolve caffeine tolerance, medication interactions, or sleep disruption.
Should I use a pre-workout shot every session?
Not necessarily. Reserve stimulants for sessions where they fit your schedule and avoid relying on them to cover chronic fatigue, inadequate food, or poor sleep.
Bottom Line
REDCON1 Total War Ready to Drink, Rainbow Candy, wins on price and clear 365 mg caffeine disclosure for experienced users who want a high-stimulant RTD. It is not our default recommendation for everyone. Frog Fuel Ultra is the more conservative convenience choice because its stated 120 mg dose leaves much more room for normal daily caffeine. Pick the smallest dose that does the job, keep your label in view, and use our pre-workout meal guide when food and timing are the real problem.
