BASE Alchemy Labs | Stim & Slim | 60 Capsules
$44.95
Alchemy Labs | AL Creatine Mono | 75 Servings
$34.95$0.46/srv 75 servings

Stim & Slim handles the energy, appetite, and thermogenic side of a cut, but it does not include creatine. Adding 3-5g daily creatine supports phosphocreatine replenishment and helps preserve power output and training quality while calories are reduced.

Take daily at any time; can be taken alongside Stim & Slim pre-workout or separately with a meal.

Whey Isolate or Lean Protein PowderPROTEIN

Thermogenics help adherence, but body-composition progress still depends heavily on protein intake. A fast-digesting protein supports satiety, recovery, and lean mass retention while Stim & Slim helps control appetite and maintain training intensity.

Use post-workout or between meals to help hit daily protein targets.

Alchemy Labs | PUMP 365 | 120 Capsules
$39.99$1.33/srv 30 servings

Stim & Slim is not a nitric oxide formula, so pairing it with a stimulant-free pump product can improve blood flow, muscle fullness, and workout feel without adding more caffeine. This is a smart stack for users who want cutting support and gym performance in the same session.

Take together 20-30 minutes before training, provided the pump formula is stimulant-free.

Electrolyte Hydration FormulaHYDRATION ELECTROLYTE

High-stim thermogenics often increase sweating, body warmth, and fluid needs, especially during cardio or training in a deficit. Adding sodium, potassium, and magnesium support can improve training quality and reduce the washed-out feeling that sometimes gets mistaken for poor stimulant response.

Use before, during, or after training; especially useful when taking Stim & Slim pre-cardio.

Sleep/Recovery SupportSLEEP

Aggressive stimulant use during cutting phases can strain recovery if timing is poor or sleep quality slips. A nighttime recovery supplement helps offset one of the most common weak points in any stimulant-driven fat-loss phase: inadequate sleep undermining appetite control, training quality, and body composition.

Use in the evening only, well separated from Stim & Slim.

Full Product Description Article

Alchemy Labs Stim & Slim is a high-stim thermogenic capsule designed around one clear objective: increase output, sharpen focus, and push calorie-burning pathways with a layered stimulant-thermogenic architecture instead of relying on caffeine alone. This is not a “fat burner” in the lazy sense of underdosed botanicals and vague marketing. The formula uses multiple pathways: central nervous system stimulation, catecholamine support, alpha-2 receptor antagonism, TRPV1 thermogenesis, and brown adipose tissue activation. That gives it a more sophisticated profile than capsule formulas that simply spike heart rate and call it metabolism.

The energy backbone starts with 200mg caffeine anhydrous for fast onset, then adds two buffered caffeine forms: 50mg Infinergy™ caffeine citrate and 50mg Infinergy™ di-caffeine malate yielding 38mg caffeine. That brings total caffeine to 263mg, with a quicker front-end rise from anhydrous and citrate, then a smoother tail from malate. In practice, that means a stronger launch and less of the abrupt drop common with single-source stimulant products. Theobromine at 75mg extends the methylxanthine profile further. While below the 250-500mg range often used in blood pressure or alertness research, it is still a useful support dose here for mild stimulation, smoother mood, and bronchodilatory/vasodilatory support alongside caffeine.

L-Tyrosine at 500mg is included to support catecholamine synthesis. It is below the high acute stress-research range of roughly 100-150mg/kg bodyweight, so this is not a fully clinical standalone tyrosine dose. But in a thermogenic formula, it still makes formulation sense: caffeine and rauwolscine accelerate sympathetic output, and tyrosine provides substrate support for dopamine and norepinephrine production when training stress, dieting, and sleep debt start draining mental sharpness.

The thermogenic side is where this formula separates itself. Advantra Z® at 150mg is a strong dose of standardized Citrus aurantium extract, supplying synephrine activity that complements caffeine through adrenergic stimulation. CaloriBurn GP® at 30mg is right in the human research sweet spot for grains of paradise, a dose associated with increased brown adipose tissue activation and higher energy expenditure. Evothin™ at 30mg matches the emerging-use target dose for evodiamine, a non-pungent TRPV1 agonist designed to mimic heat-producing pathways similar to capsaicin without relying entirely on sensory burn. Capsaicin is listed at 100mg from a 1% capsaicinoid extract, which yields about 100mg capsaicinoids. That places it just under the commonly studied 1.2-12mg range, so this is best viewed as a supportive thermogenic layer rather than a clinically dosed capsaicin centerpiece.

Rauwolscine at 1.5mg is fully in the effective range and one of the formula’s most powerful levers. As an alpha-2 adrenergic antagonist, it increases noradrenergic signaling and is especially relevant for appetite suppression and mobilization of stubborn fat. This is also the ingredient that makes Stim & Slim clearly high-stim rather than moderate. Sensitive users often feel rauwolscine as heightened urgency, stronger thermogenesis, and more pronounced appetite blunting.

Niacin at 15mg is not here as a pharmacological lipid dose; it is simply a basic vitamin-level inclusion supporting NAD/NADP-dependent energy metabolism. Transparency is a major positive here: no proprietary blend, every active disclosed, and trademarked ingredients identified. In a category full of hidden stimulant matrices, that matters.

What to expect: day one is about noticeable energy, warmer body temperature, stronger drive, and reduced appetite. Over 2-4 weeks, the biggest practical benefit is not “fat melting,” but more consistent training output and dietary adherence while cutting. That is where this formula earns its place.

Science & Clinical References 11 citations
Layered Caffeine Pharmacokinetics0 studies

Stim & Slim uses multiple caffeine forms to shape onset and persistence rather than relying on a single anhydrous bolus. Caffeine anhydrous generally drives the sharper front-end rise in plasma caffeine, while citrate and malate forms can influence perceived smoothness and duration through staggered delivery characteristics. Mechanistically, caffeine antagonizes adenosine receptors, reducing perceived fatigue and increasing alertness, training readiness, and sympathetic drive. In practice, this supports both mental intensity and sustained output during calorie restriction.

Tyrosine and Catecholamine Support5 studies

L-tyrosine serves as a precursor for catecholamine neurotransmitters including dopamine and norepinephrine. Under stressful conditions such as dieting, sleep restriction, or hard training, precursor availability may help preserve aspects of cognitive performance and task engagement. Its value is usually most noticeable as a support ingredient that makes a stimulant formula feel more focused and less mentally scattered. This is especially relevant in cutting phases where motivation and concentration often decline.

TRPV1 Thermogenesis and Capsaicin5 studies

Capsaicin activates TRPV1 receptors, which can increase thermogenic signaling and the subjective sensation of warmth. That receptor activity is linked to transient increases in energy expenditure and may also modestly affect appetite and food intake in some users. The effect is not magic fat loss by itself, but it meaningfully complements a stimulant-based thermogenic framework. Its inclusion helps distinguish true heat-support formulas from products that are simply high in caffeine.

Brown Adipose Tissue Activation0 studies

Grains of paradise extracts standardized for 6-paradol have attracted interest for their ability to increase thermogenic activity partly through brown adipose tissue-related pathways. Brown adipose tissue is metabolically active and dissipates energy as heat, making it a relevant target in modern thermogenic design. While outcome data are still developing, the ingredient fits well mechanistically in formulas aimed at increasing calorie expenditure. It is best viewed as a supportive amplifier rather than a standalone fat-loss driver.

Absorption Enhancement with Piperine1 studies

Piperine from black pepper extract is often used to enhance absorption kinetics of certain nutrients and phytochemicals. Proposed mechanisms include effects on intestinal transport, membrane dynamics, and enzyme activity involved in metabolism. In a complex thermogenic formula, this may help improve overall ingredient exposure, particularly for botanical actives. Its role is supportive, but at evidence-based doses it can improve formulation efficiency.

Quick Answers

How much caffeine is in Alchemy Labs Stim & Slim?

A full 2-capsule serving provides 263mg total caffeine. That comes from 200mg caffeine anhydrous, 50mg Infinergy™ caffeine citrate, and 50mg Infinergy™ di-caffeine malate yielding 38mg caffeine, giving the formula both fast onset and more sustained stimulation.

Is Stim & Slim a beginner-friendly fat burner?

No. The combination of 263mg total caffeine, 1.5mg rauwolscine, and 150mg Advantra Z® makes this a high-stim product better suited to experienced users. Beginners should start with 1 capsule or choose a milder thermogenic.

What does rauwolscine do in this formula?

Rauwolscine is an alpha-2 adrenergic antagonist used here at 1.5mg, which is an effective dose. It helps keep norepinephrine signaling elevated, which can support appetite suppression, a more intense thermogenic feel, and mobilization of stubborn fat.

Why does this formula use multiple caffeine sources instead of just caffeine anhydrous?

Alchemy Labs combines fast-acting caffeine anhydrous with buffered forms from Infinergy™ to create a more layered energy profile. The goal is a stronger initial lift with less abrupt drop-off than you typically get from a single-source stimulant formula.

When should I take Stim & Slim?

Take it 20-30 minutes before training, cardio, or the time of day when you need the strongest energy and appetite-control effect. Many users prefer it pre-workout or before fasted morning cardio, but avoid taking it too close to bedtime.

Can I stack Stim & Slim with pre-workout?

Usually not with a stimulant pre-workout. Since Stim & Slim already contains 200mg caffeine plus rauwolscine and Advantra Z®, it is smarter to pair it with a stim-free pump formula, creatine, electrolytes, or protein instead of adding more stimulants.

Is CaloriBurn GP® actually dosed effectively here?

Yes. CaloriBurn GP® is included at 30mg, which aligns with the clinically relevant range used for grains of paradise in thermogenic and brown adipose tissue research.

Will this product make me feel warm or sweaty?

Many users notice increased body warmth, especially when taken fasted or before cardio. That comes from the combined thermogenic action of CaloriBurn GP®, capsaicin, Evothin™, Advantra Z®, and rauwolscine-driven sympathetic activity.

Does Stim & Slim contain a proprietary blend?

No. One of the strongest aspects of this formula is full disclosure. Every active ingredient and every dose is listed clearly on the label.

Can I use Stim & Slim every day?

You can use it daily during a defined cutting phase, but it is wise to monitor tolerance and avoid indefinite long-term use without breaks. Caffeine tolerance builds, and aggressive stimulant products are best used strategically rather than mindlessly year-round.
