Layered caffeine, theacrine, and rauwolscine in one easy cutting cap
Purus Labs TheaTrim is a stim-based fat burner in one simple capsule. The goal? Give you better energy for fat loss than plain caffeine, without overcomplicating things. It's not a full metabolism booster or a chill non-stim option. It's all about cranking up alertness, making workouts or cardio easier, and adding that hunger-curbing vibe you need on a cut.
At the heart is a 278mg blend with 150mg total caffeine from Infinergy® dicaffeine malate (that's caffeine bonded to malic acid for slower release), extra caffeine, and theacrine. 150mg is a solid amount per cap – not too much, but enough to feel it. Infinergy® slows down how fast it hits, so it's steadier than quick caffeine. Caffeine blocks adenosine receptors (those make you feel tired), cuts fatigue, and boosts feel-good chemicals. The malate part helps with energy production in your cells. In real life, it feels like a smooth build-up, not a crash.
Theacrine layers on nicely. Studies show it boosts energy, mood, and focus, especially with caffeine. It hits similar fatigue paths but also dopamine for that motivated feel. Downside: no exact dose listed, and good studies use 50-125mg. So it's a smart add, but you can't check if it's dosed right.
Rauwolfia vomitoria extract gives 500mcg rauwolscine. That's tiny but powerful. Rauwolscine blocks alpha-2 adrenergic receptors
Purus Labs Theatrim by Purus Labs contains 250mcg Vitamin B12, a effective dose for training performance and pump.
Key Highlights
- 150mg total caffeine per cap – enough for a real energy boost without going overboard. It comes from different sources including Infinergy®, so it feels steady and not just a quick hit like basic stim burners.
- Infinergy® dicaffeine malate – a special caffeine tied to malic acid to ease it in slower. This buffers the gut and spread-out release, while caffeine still wakes you up by blocking tired signals and cutting fatigue.
- Theacrine teamed up with caffeine – one of the best combos in supps right now. It works on fatigue and dopamine paths, so you get cleaner mood, drive, and focus than piling on more caffeine.
- 500mcg rauwolscine from Rauwolfia vomitoria – small dose, big punch. It blocks alpha-2 receptors for that sharp fat-burn feel, better hunger control, and wired energy that serious cutters love.
- One-cap serving – super convenient for a real stim fat burner. No mixing, no tub to lug around – perfect for quick pre-cardio or diet support on the go.
- SAMe at 125mg – not a huge mood dose on its own, but it helps keep things calm under stims. It supports brain chemicals and methylation for a driven feel without the edge.
- 125mg citrus bioflavonoid complex from hesperidin – throws in some blood flow and antioxidant help to a stim-heavy formula. Not the star, but it rounds things out better than a plain caffeine pill.
- 80mg white willow bark extract with salicin – brings a classic anti-inflammatory touch that tweaks the overall vibe. Not the main fat-loss player, but it's old-school thermogenic style.

Who Is This For?
- Lifters on a cut whose gym fire and daily hustle drop with lower food. 150mg caffeine, theacrine, and rauwolscine combo brings back the urgency, sharpens focus, and makes low-cal workouts doable.
- Early cardio folks wanting a simple thermogenic over scoop pres. One cap is quick for fasted walks, treadmill, or conditioning, with Infinergy® and caffeine for smoother energy than coffee alone.
- Pros cutting fat who need hunger control and work focus as much as gym energy. Caffeine and theacrine boost brain power, rauwolscine adds the kick when tiredness and cravings rise.
- Mid-level supp users who know stims and want better than generic burners. This has a clear stim setup, not random weak herbs with no real feel.
- Capsule fans over powders for easy, portable doses. TheaTrim suits travel, desk, and quick routines better than full powdered thermogenics or stacks.
- Physique competitors in cut phases needing motivation more than pump or strength. It's a stim tool for staying dialed when calories drop, not a full pre with extras.
How to Use
Take 1 cap 20-30 minutes before training, cardio, or your tough appetite spots. If you're new to stims or rauwolscine, start with just one and skip other caffeine first. Swallow with water – no mixing needed, but a full glass helps. Empty stomach makes stims and rauwolscine hit stronger, but if your gut's picky, pair with light food. Skip late-day use – 150mg caffeine plus theacrine can mess with sleep if you're sensitive. Don't mix blindly with high-stim pres, drinks, or burners, especially yohimbine, rauwolscine, synephrine stuff. Goes great with creatine, electrolytes, and protein-focused eating. No must-cycle for healthy folks who handle stims, but breaks keep tolerance down and feel fresh. Store cool and dry with lid tight to keep caps good.
What to Expect
First 10 minutes, you might not feel much – it's a cap, not a powder with instant taste. 10-25 minutes in, stims start kicking – usually a steady alertness and readiness, not a rush. 25-60 minutes is prime time: energy up, hunger down, rauwolscine adding edge, warmth, or drive. 60-120 minutes, Infinergy® and theacrine keep it going strong without a hard drop. Over the first week, you figure out the best spot – pre-training, cardio, or work slumps. By weeks 2-4, it's about consistency: more solid sessions, easier hunger handling, and sticking to the plan when calories suck.

Frequently Asked Questions
How much caffeine is in Purus Labs TheaTrim per serving?
TheaTrim provides 150mg total caffeine per 1-capsule serving. That caffeine comes from a blend including Infinergy® dicaffeine malate and additional caffeine, which is designed to feel more layered than a standard caffeine-only capsule.
Is the theacrine dose fully disclosed in TheaTrim?
No. The label discloses a 278mg excitatory blend containing Infinergy®, theacrine, and caffeine, and it confirms 150mg total caffeine, but it does not list the individual theacrine amount. That means you know the total stimulant load reasonably well, but not the exact milligrams of theacrine.
What does Infinergy® do in this formula?
Infinergy® is a trademarked dicaffeine malate ingredient that combines caffeine with malic acid. The goal is a smoother, more sustained stimulant profile because the caffeine is delivered in a buffered form rather than as only a fast-acting source.
Will TheaTrim feel stronger than 150mg caffeine sounds?
For many users, yes. Theacrine can make the energy feel more focused and motivation-driven, and rauwolscine often adds a sharper thermogenic edge, so the overall experience can feel more aggressive than the caffeine number alone would suggest.
Is TheaTrim good for fasted cardio?
Yes, that is one of the best use cases for it. The one-capsule format, moderate total caffeine, and rauwolscine-driven thermogenic feel make it a practical option before morning walks, incline treadmill work, or other low-to-moderate intensity fat-loss cardio.
Can I stack TheaTrim with pre-workout?
Use caution. Because TheaTrim already contains 150mg caffeine plus theacrine and rauwolscine, stacking it with a high-stim pre-workout can push the overall stimulant load too high for many users. It is usually better paired with stim-free or low-stim training support if you want to combine products.
What should I expect from the rauwolscine in TheaTrim?
At 500mcg standardized rauwolscine, many experienced users notice stronger appetite suppression, more internal drive, and a warmer, more thermogenic feel. Sensitive users may also notice increased jitters, restlessness, or a more pronounced stimulant edge.
Is TheaTrim a good choice for beginners?
Not usually. Even though the caffeine amount is not extremely high, the addition of theacrine and rauwolscine makes the formula more advanced than a basic caffeine supplement. Most beginners do better starting with plain caffeine or a lower-complexity thermogenic.
Does TheaTrim need to be cycled?
It does not require cycling because of a loading ingredient like creatine or beta-alanine, but many users benefit from periodic breaks to manage stimulant tolerance. If the energy and appetite effects become less noticeable over time, a short stimulant deload often restores responsiveness.
Why are SAMe and citrus bioflavonoids included?
They appear to be supportive ingredients that shape the overall feel of the formula rather than act as major fat-loss drivers. SAMe adds mood and methylation support, while citrus bioflavonoids contribute antioxidant and vascular-support logic.
