Solid caffeine dose, premium thermogenics, no-BS fat-burning help.
Raw x CBUM Essential Fat Burner is a straightforward, stim-based thermogenic that focuses on mixing moderate caffeine with different ways to boost your burn, instead of just piling on caffeine. That's key because a lot of fat burners out there just overload you with stims for a quick rush that crashes hard. This one layers it up: caffeine for that CNS kick, theobromine for a smoother ride, grains of paradise and capsicum for thermogenic action, and GBB HCl to hit the carnitine angle.
The energy comes from 200mg total caffeine: 150mg straight anhydrous plus 50mg from 239mg guarana extract at 22% caffeine. Caffeine blocks adenosine receptors, which means more alertness, less feeling of effort, and better performance when calories are low. At 200mg, it's a moderate dose—enough to perk you up and help with appetite without going full throttle like some high-stim options.
You get 250mg green tea leaf extract, a go-to for fat loss thanks to its catechins like EGCG, which help with energy burn and fat use. No exact standardization listed, so it depends on the extract, but green tea's got solid backing in this space.
100mg theobromine is a nice touch—it's gentler than caffeine but gives a smoother, longer-lasting energy without the sharp edges. Some early studies show heart and metabolic perks, though not as dialed-in for performance as caffeine. It pairs great with caffeine: quick hit from caffeine, steadier feel from theobromine to round out the exper

Key Highlights
- 200mg total caffeine from two spots—150mg anhydrous plus 50mg from guarana extract. You get a quick kick from the anhydrous and a bit more spread-out energy than just one source.
- 239mg guarana extract at 22% caffeine—not just for show. It brings natural caffeine and teams up with the anhydrous for energy that feels more even.
- 100mg theobromine for smoother energy with some heat. It's milder than caffeine and helps stretch out the boost without making things feel too intense.
- 250mg green tea leaf extract throws in a proven fat-loss helper. It's popular for its catechins that support burning calories and fat, especially with caffeine in the mix.
- 50mg Gamma-Butyrobetaine HCl hits the carnitine path. GBB is common in thermogenics because a lot of people feel more heat and sweat from it.
- 30mg CaloriBurn GP® Grains of Paradise is a standout here. This branded ingredient gets props for firing up brown fat and boosting how many calories you burn through heat.
- 25mg Capsimax® gives a cleaner capsicum boost than plain cayenne. The special delivery makes it easier on the stomach while still ramping up heat and burn.
- 5mg BioPerine® boosts how well everything absorbs. In capsules like this, black pepper extract helps make sure you get the most out of the ingredients.

Who Is This For?
- Physique folks cutting who want to keep training strong as calories drop. 200mg caffeine helps alertness and push, while CaloriBurn GP®, Capsimax®, and GBB HCl make it a real thermogenic, not just caffeine.
- Fasted morning cardio fans needing a capsule thermogenic without insane stims. Moderate caffeine boosts drive and energy, theobromine keeps it smooth.
- Lifters recomping who want burn support without max stims. Good for tightening diet, upping steps, and getting an edge in consistency over a stim bomb.
- Busy people dieting for beach season who train early and need something easy. Two caps give a clear formula, no guessing, supporting energy, heat, and focus on lower food.

- Athletes who find high-stim burners too shaky or sleep-killing but want real cut support. 200mg caffeine with 100mg theobromine is a sweet spot between weak energies and hardcore stuff.
How to Use
Take 2 capsules for a full serving 20-30 minutes before training, cardio, or your busy time. If stims hit you hard, start with 1 cap for a few days; it's got 200mg caffeine total, 100mg theobromine, and thermogenics that can make it feel bigger. Capsules mean no mixing—just down with water. Some like it with a small meal if stims or spicy stuff bugs their stomach, but empty stomach often means quicker action. Stack smart: count caffeine from pre-workouts or drinks to not overdo it. Pairs great with creatine, electrolytes, and high-protein eats during cuts. No need for strict cycling, but breaks help with caffeine tolerance on longer runs. Keep it cool and dry—don't let the bottle bake in your car or gym bag.
What to Expect
First 0-10 minutes: not much right away, maybe just a hint you're gearing up, especially with food. 10-25 minutes: caffeine kicks in—sharper mind, more motivation, early thermogenic signs. 25-45 minutes: this is peak notice time, with real warmth, sweat potential, and that 'on' vibe from caffeine, guarana, and theobromine. 45-120 minutes: energy stays steady, not spiky, thanks to theobromine smoothing it. Days 1-7: you feel more consistent in cardio, dieting, and drive. Weeks 2-4: it's about better flow in your cut—stronger sessions, less slog, easier to stay on track. Watch extra caffeine to avoid building tolerance; timing's key.

Frequently Asked Questions
How much caffeine is in Raw x CBUM Essential Fat Burner?
Each 2-capsule serving provides 200mg total caffeine. That comes from 150mg caffeine anhydrous plus 239mg guarana extract standardized to 22% caffeine, delivering another 50mg.
Is this a high-stim fat burner?
No—this sits in the moderate-stim category. At 200mg total caffeine, it is meaningfully energizing, but the formula leans on multi-pathway thermogenesis from CaloriBurn GP®, Capsimax®, green tea extract, and GBB HCl rather than trying to overpower you with stimulants alone.
What does the 100mg theobromine do in this formula?
Theobromine is a methylxanthine like caffeine, but it is milder and typically feels smoother. In this formula, it helps round out the energy curve and complement the faster, sharper stimulation from caffeine anhydrous.
What makes CaloriBurn GP® special?
CaloriBurn GP® is a trademarked grains of paradise extract with human research supporting brown adipose tissue activation and increased thermogenic energy expenditure. It is one of the more compelling premium thermogenic ingredients in this formula because it works through a distinct pathway beyond simple stimulation.
Will this make me feel hot or sweat more?
Many users report exactly that with formulas built like this. GBB HCl, CaloriBurn GP®, and Capsimax® are all associated with a stronger thermogenic feel, which can show up as increased warmth and sweat response during activity.
Can I take this with pre-workout?
You can, but you need to count total stimulants carefully. This product already gives you 200mg caffeine plus 100mg theobromine, so stacking it with a fully dosed pre-workout can quickly push total stimulant intake too high for many users.
Should I take it with food or on an empty stomach?
Taking it on a relatively empty stomach often leads to faster onset and a more noticeable effect. If you are sensitive to stimulants or spicy thermogenic ingredients like Capsimax® and BioPerine®, a light meal can improve comfort.
Is this good for fasted cardio?
Yes, this is a strong use case for the formula. The capsule format, moderate caffeine dose, and thermogenic ingredient profile make it well suited for morning cardio before breakfast if you tolerate stimulants well.
Does this formula use a proprietary blend?
No. Every active ingredient and its dose is disclosed on the label, which is a major transparency advantage in the fat burner category.
How long before bed should I avoid taking it?
As a rule, keep it at least 6 hours away from bedtime, and often longer if you are caffeine-sensitive. Between 200mg total caffeine and 100mg theobromine, late-day use can interfere with sleep quality.
