Stacked caffeine, rauwolscine, and legit thermogenic brands

Stim & Slim is a high-stim thermogenic capsule that aims to boost your output, sharpen focus, and crank up calorie burn with a smart mix of stims and thermogenics, not just caffeine overload. This isn't one of those weak fat burners with underdosed plants and hype. It hits multiple angles: revving your central nervous system, supporting feel-good chemicals, blocking alpha-2 receptors (which helps keep energy signals firing), firing up TRPV1 for heat, and activating brown fat for more burn.

Energy starts with 200mg caffeine anhydrous for a quick kick, plus two buffered versions: 50mg Infinergy™ caffeine citrate and 50mg Infinergy™ di-caffeine malate, adding up to 38mg more caffeine. Total's 263mg, so you feel a fast alert spike from the anhydrous and citrate, then a steady ride from malate. No sharp crash like single-source stims. Theobromine at 75mg adds to the mix—it's below the big doses in studies for blood pressure or alertness, but here it helps with mild energy, better mood, and easier breathing or blood flow with caffeine.

L-Tyrosine at 500mg backs up your body's production of dopamine and norepinephrine—key for drive. It's under the high-stress study doses of 100-150mg per kg of bodyweight, so not a full solo hit. But in this thermogenic, it fits: caffeine and rauwolscine amp up your system, and tyrosine gives the building blocks when training, dieting, and lack of sleep zap your sharpness.

The thermogenic part stands out. Advantra Z® at 150mg is a solid dose of standardized Citrus au

Alchemy Stim & Slim by Alchemy Labs contains 15mg Niacin, a clinical dose for training performance and pump.

Key Highlights

  • 263mg total caffeine from three spots—200mg anhydrous plus Infinergy™ caffeine citrate and di-caffeine malate. You get a quick alert boost that lasts longer than plain anhydrous stuff.
  • 1.5mg rauwolscine—spot on for advanced users chasing better hunger control and help with tough fat spots. It blocks alpha-2 receptors to keep norepinephrine pumping, so energy doesn't fizzle fast.
  • 150mg Advantra Z®—a real dose of standardized Citrus aurantium extract, not just a name drop. This drives metabolism alongside caffeine for a fuller thermogenic punch.
  • 30mg CaloriBurn GP®—that's the dose that shows up in studies for firing up brown fat and bumping energy burn. Not just a tiny add-in.
  • 30mg Evothin™—hits the common sweet spot for evodiamine thermogenics. It taps TRPV1 heat channels, adding another burn layer beyond stims.
  • 500mg L-Tyrosine—helps make stress-busting brain chemicals, key during cuts when focus slips. Not a huge standalone dose from stress studies, but it pairs great with the stim-heavy setup.
  • 75mg theobromine—a gentler stim that widens the energy feel past caffeine. It smooths things out, might ease breathing and flow, making it less jittery than pure caffeine.
  • Capsaicin extract at 100mg, standardized to 1% capsaicinoids—gives about 1mg actives. A bit under typical study ranges, so think of it as backup heat, not the main driver.

Who Is This For?

  • Seasoned cutters in deficits whose drive tanks after a couple weeks. 263mg caffeine, 1.5mg rauwolscine, 500mg tyrosine reinforce motivation, hunger control, output right then.
  • Fasted-cardio fans wanting capsules over sweet drinks or big pre's. 30mg CaloriBurn GP®, 150mg Advantra Z®, rauwolscine target fat loss better than plain energy pills.
  • Physique folks leaning out, needing metabolic push beyond caffeine. Dual Infinergy™ plus theobromine layers energy, Evothin™ and capsaicin add TRPV1 heat.
  • Pros training post-work when low cals and stress hit. L-Tyrosine backs catecholamines, staggered caffeine keeps focus better than one big hit.
  • High-tolerance stim users where weak burners do nothing. 1.5mg rauwolscine and 150mg Advantra Z® make it punchier than starters.
  • Lifters in cut blocks holding gym gains while dropping fat. Supports energy, mood, appetite for recomp, not a pump pre.

How to Use

Try 1 capsule first to check tolerance, especially new to rauwolscine or synephrine thermogenics. If good, go 2 capsules 20-30 minutes before workouts, cardio, or tough spots. Swallow with water—a full glass helps, great for fasted mornings. Empty stomach makes it hit harder for many, but if stims or capsaicin bug your stomach, eat light. Don't mix with high-stim pre's, energy drinks, yohimbine, rauwolscine, or big caffeine. Stacks fine with creatine, electrolytes, protein, or stim-free pumps for gym gains without extra stims. Use during cuts, not year-round—tolerance builds. Skip 6-8 hours before bed. Store cool and dry to keep capsules fresh.

What to Expect

First 10 minutes, not much—just waiting. 10-25 minutes in, fast stims hit: alertness climbs, hunger dips, warmth builds. 25-45 minutes is peak—caffeine, rauwolscine, Advantra Z® deliver urgency, focus, strong thermogenics. 45-90 minutes, it levels out steady, thanks to buffered caffeine and theobromine. Days 1-7, test tolerance—rauwolscine might need adjusting. Weeks 2-4 in a cut, you notice consistent training, easier cardio, better hunger control over quick body changes.

Frequently Asked Questions

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 263mg 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.

One of the Few Fuel Additives I Keep Buying
Color: Pack of 2
I've been using this product in my 2015 Ford F-150 for more than five years, and it's one of the few fuel additives that has earned a permanent spot in my maintenance routine. I originally started using it as preventive maintenance, but over time I noticed the engine seemed to run smoother after treatment. It's not the kind of product that suddenly turns your truck into a race car, but it has consistently done what I hoped it would do. I've purchased and used it multiple times over the years, which probably says more than anything else I could write. If a product doesn't work or isn't worth the money, I usually don't buy it again. This one keeps finding its way back into my shopping cart. I trust the product, I've had good results with it, and I think it's a reasonable value for the money. Based on my experience, I'll continue using it as part of my regular maintenance routine. If you believe in taking care of your vehicle before problems start, this has been a worthwhile purchase for me.

Mechanic Recommends Sea Foam -- Best Gas Treatment for All Engines
Color: Pack of 1
We have a small-engine mechanic who turned us onto SeaFoam motor treatment -- and against most gasoline preservatives and treatments. He said he'd drained, or seen inside, thousands of gasoline tanks, and the stuff sold as gasoline storage additives was often still there, sitting as gel on the bottom of the tank. Just gunk. He also said most brands of engine treatment weren't worth the money. However, he swore by SeaFoam, which I'd never tried at the time, and my experience since has proved him out. I've had many rough-running engines find their power and performance again, with nothing different, but a shot of SeaFoam in the gas tank (and the crankcase). We own a number of vehicles and equipment with small engines, from a compact backhoe, to a ride'em Husqvarna mower, weedwacker, chainsaw -- and on the larger size, a Honda SUV and Ford F150 pickup. All of them have benefited greatly from the regular use of SeaFoam. However, when we're running the road vehicles a lot, especially in the summer, we go through gas and don't necessarily add SeaFoam with every fill. Recently, the Ford began to run rough. It stalled as I pulled up to corners and lights. In the past, that would have meant a mechanic and an expensive tune-up. All I did was go for a fill-up, and started by adding a full can of SeaFoam. Problem solved, just like that. The Terramite (made in the USA) backhoe is not used a lot -- and as with most motors, that is a problem. It's bad for an engine not to run it -- and especially, in most cases, for it to sit with gas in the tank. The backhoe has a Kohler Command 25-horse gasoline engine that powers the hydraulics that run the wheels, steering, front-loader, and backhoe. I change the spark plugs each season, but it, like my Stihl chainsaw, and 6500 watt backup (gasoline) generator, and for that matter, all the small engines, can be hard to start after a hiatus. And even when they get going, they'll run rough. I used to drain the tanks frequently, then run them dry, then fill again before use, and hope for the best. But SeaFoam has changed all that. Throughout the summer, I can leave treated gas in the tank, and have little problems with starts or rough running. In the smaller equipment, I dose the gasoline with each fill (1 oz per gallon), as SeaFoam cleans both carburetors and full injection systems. It is good for gasoline and diesel engines. Added to your crankcase (1.5 oz per quart of oil), it cleans deposits and quiets noisy lifters. These days, most gasoline is mixed with ethanol and that's a bad thing for small engines. Ethanol goes hand in hand with water -- and as we all know, water in the gas is anathema to motors. Again, my small engine mechanic told me, 90% of the no-start problems he had to deal with were caused by ethanol-caused water in the fuel system. SeaFoam actually controls moisture and prevents this problem. It also de-ices and is anti-gel. In my opinion, when it comes to gasoline and diesel engines, large and small, SeaFoam is THE Silver Bullet. My equipment is often running, while my neighbors are running with theirs to the shop. I've told many about SeaFoam, but some people seem to want to do it the hard way. By the way, I also swear by PRI-G fuel additive for long-term gasoline storage. I keep 100 gallons of gas in tanks for emergency use. We are in a rural, wilderness area. I was introduced to that by survival expert, Steve Harris. He said he's had gasoline that was 10 years old still run equipment, because he'd added PRI-G to it (you can buy here on Amazon). Of course, you have to remember to add more PRI-G each year -- that's the catch. So our rule of thumb is, PRI-G for long term fuel storage -- and SeaFoam for month to month. Also -- this price is right! Of course, when you compare the cost of equipment breakdown, and having to take anything to a mechanic, this is almost free. However, apples to apples, this price is cheaper than Walmart -- and up to $4 cheaper per can than many auto supply and hardware stores. Can't say enough good things about this product! Highly recommended.

I swear by Seafoam, especially for small engines
Color: 3 Pack
I swear by Seafoam. It has really helped out my small engines, especially the 2 strokes and ones that sit around for long periods of time like my leaf blower and roto tiller. After I started adding Seafoam every time I get fuel I have had zero starting issues. They can sit all year and they will still start right up. In my car/trucks with higher miles I've used it to clean out the crankcase with great results. I add a can to the oil right before doing an oil change. I add a can then take a short drive(10 miles) to make sure the oil is up to operating temperature and change the oil once I get home. It does a good job cleaning any sludge out of the pan and the new oil stays looking fresh/clean way longer.
