High-stim fat burner tablet with 150mg caffeine and 25mg synephrine.

Hi-Tech Pharmaceuticals Stimerex-ES isn't your everyday energy pill or one of those mild fat burners with clean labels. This is an old-school high-stim fat burner tablet that's all about mixing different stim paths to ramp up your alertness, workout drive, and fat-cutting power. It combines 150mg caffeine anhydrous with a 510mg proprietary blend that has ephedra leaf extract, Senegalia berlandieri alkaloids, 2-aminoisoheptane HCl, theobromine, Citrus aurantium giving 25mg synephrine, green tea extract, yohimbe extract, naringin, and 6,7-dihydroxybergamottin.

That 150mg caffeine is fully listed, so you know exactly what you're getting as the base. Caffeine blocks adenosine receptors—that's the stuff that makes you feel tired—so it sharpens you up and cuts fatigue. Here, it feels way stronger than just 150mg because it's backed by a ton of other stims.

Citrus aurantium delivers 25mg synephrine, a solid amount you see in fat burners for boosting metabolism and curbing appetite through adrenaline-like effects, especially when dieting. Ephedra leaf extract is in at 25mg, but without details on the active parts, it's hard to pin down exact strength—still, it's there for that classic fat-burning vibe.

Senegalia berlandieri extract brings phenylethylamine alkaloids like phenylethylamine, methylsynephrine, N-methyl-beta-phenylethylamine, and N,N-dimethylphenylethylamine. These hit quick for mood lifts, urgency, and extra stim kick that you feel right away.

Hi Tech Stimerex-Es by Hi Tech contains 150mg Caffeine (anhydrous), a effective dose for training performance and pump.

Key Highlights

  • 150mg Caffeine Anhydrous — this is your solid base for quick alertness by blocking that tired feeling. In this mix, that 150mg packs more punch than a plain caffeine pill because it's stacked with other stims in the proprietary blend.
  • 25mg Synephrine from Citrus Aurantium — a good dose for fat-burning support that amps up energy and helps with dieting through adrenaline effects. It's one of the few things here with a clear amount, so you can judge it easily.
  • 510mg Proprietary Stimulant Blend — this is where most of the power comes from, blending a bunch of ingredients for a deeper, harder-hitting feel instead of just relying on caffeine. The good side is a stacked experience; the downside is you don't see individual doses for the big players.
  • Ephedra Leaf Extract at 25mg — thrown in to give that throwback fat-burner edge. No details on the active strength, so you know it's there but not exactly how potent.
  • Senegalia Berlandieri Extract — delivers phenylethylamine alkaloids like phenylethylamine and methylsynephrine types. These are great for fast mood boosts, drive, and that early stim intensity you notice right off the bat.
  • 2-Aminoisoheptane HCl — another stim to stretch and crank up the brain buzz beyond caffeine. Dose isn't shown, so think of it as part of what makes this a serious high-stim option.
  • Theobromine — helps smooth out the energy so it's not all spike and crash. Studies show it's different from caffeine, often used here for a steadier, longer stim feel.
  • Yohimbe Extract — a classic in tough fat burners for extra adrenaline kick. It can ramp up intensity and diet motivation for the right person, but for others, it might make things feel too edgy.

Who Is This For?

  • Seasoned dieters in deep calorie cuts needing a strong boost for cardio or mornings. The 150mg caffeine, 25mg synephrine, yohimbe, and hidden stims focus on drive, alertness, and hunger control over easy vibes.
  • Pro stim users who know their limits from multi-stim stuff, not just caffeine. It's spot-on for those who get yohimbe, synephrine, and DMHA, wanting that stacked feel in a tablet.
  • Early risers doing fasted cardio or low-cal workouts who want real motivation without chugging pre-workout. Tablets are handy, and it's more about heat and mental kick than pumps or fluids.
  • Bodybuilders cutting who'll take edgier energy for better fat burn. It's for folks who want to feel on fire, warmer, and pumped when low cals zap your spark.
  • Busy folks using a fat burner for focused energy in cut phases. Caffeine, theobromine, PEA alkaloids, and adrenaline boosters crank up your task power.
  • People who like tablets over powders for a portable fat burner before sessions. Great if you skip flavors, pumps, or big scoops and just want hard-hitting heat.

How to Use

Kick off with 1 tablet to check how it sits, about 20-30 minutes before training, cardio, or your big energy need. It's high-stim with extra hidden stuff beyond the 150mg caffeine, so don't treat it like casual coffee first time. Empty stomach speeds it up for many, but if stims bug your gut, add a light bite. Wash it down with water. Skip stacking with other stim-heavy gear like pre-workouts or big coffees unless you've got the experience. Pair with non-stims like creatine, electrolytes, or protein instead. Cycle it to fight tolerance—don't run forever. Keep it sealed in a cool, dry spot away from heat.

What to Expect

First 10-15 minutes, no hassle with mixing like powders, so it's easy for fasted starts. By 15-30 minutes, caffeine brings the initial alertness, then the blend adds real heat and stim punch. Peak hits around 30-60 minutes: more drive, sweat, sharp focus, and that fat-burner vibe stronger than plain caffeine. From 60-120 minutes, theobromine and mix keep it going without a hard crash. Days 1-7, you'll figure quick if yohimbe and synephrine work for you. Weeks 2-4, it's not about building up but adapting—tolerance can soften the edge, so cycling keeps it fresh.

Frequently Asked Questions

How much caffeine is in Stimerex-ES per tablet?

Each tablet provides 150mg caffeine anhydrous. The important context is that the formula also contains multiple additional stimulants inside a 510mg proprietary blend, so the real-world intensity feels stronger than a standalone 150mg caffeine product.

Is Stimerex-ES a pre-workout or a fat burner?

It is best classified as a high-stim thermogenic fat burner that can also be used before training or cardio. It does not contain classic pre-workout performance ingredients like citrulline, beta-alanine, or creatine; instead, it focuses on stimulant drive, thermogenesis, and dieting intensity.

What makes this formula feel stronger than the caffeine number suggests?

Beyond the 150mg caffeine, the proprietary blend includes 25mg synephrine, ephedra extract, yohimbe extract, 2-aminoisoheptane HCl, Senegalia berlandieri alkaloids, and theobromine. Those ingredients create a layered stimulant effect that most users perceive as considerably more aggressive than caffeine alone.

When should I take Stimerex-ES?

Take 1 tablet about 20-30 minutes before cardio, training, or the time of day when you want the strongest thermogenic push. Many experienced users prefer it before fasted cardio, but stimulant-sensitive users may tolerate it better with a light meal.

Can I stack Stimerex-ES with coffee or pre-workout?

In most cases, no. Since the formula already combines 150mg caffeine with several additional stimulants, stacking it with coffee, energy drinks, or a full stim pre-workout can push the experience into uncomfortable territory very quickly.

Is the formula fully transparent?

No. Caffeine is disclosed at 150mg, and the formula confirms 25mg ephedra extract plus 25mg synephrine within a 510mg proprietary blend, but most of the important actives inside that blend do not have individual doses listed.

What does theobromine add to a formula like this?

Theobromine is often used to create a smoother, more extended stimulant curve than caffeine alone. In Stimerex-ES, it likely helps broaden the energy feel so the formula is not just an immediate spike and drop.

Who should avoid this product?

Beginners, stimulant-sensitive users, pregnant or nursing women, anyone under 18, and anyone with cardiovascular issues, high blood pressure, anxiety disorders, or stimulant-related medication interactions should avoid it. This is an advanced high-stim product, not a general wellness supplement.

Will I build tolerance to Stimerex-ES?

Yes, that is a realistic expectation with repeated use. Because the formula relies heavily on stimulant-driven effects, many users find the initial intensity softens over time and choose to cycle use during specific cutting phases.

Is Stimerex-ES good for fasted cardio?

That is one of the clearest use cases for this product. The tablet format, strong stimulant profile, and thermogenic positioning make it especially attractive for experienced users doing low-calorie or fasted morning cardio.

Garmin has been a super disappointment.
Style: Alpha TT 25
FOR THE REMOTE: For reasons I cannot fathom as a software developer, the Garmin developers chose to program the handheld to wait for GPS lock before allowing you to control the collar. This is stupid beyond belief and causes frustration that simply shouldn't be. Look Garmin, the remote should be able to communicate with the collar first and foremost. I want to be able to power everything up, put the collar on the dog, and walk out the door. If my dog sees a rabbit or deer, I want to be able to remind him not to chase. I DON'T want to stand there staring at my remote greeted by the message "Waiting for GPS" with all the buttons non-responsive. Fix this! This should be super easy to fix with a firmware update. Fix it and I'll gladly give this unit 10 stars! GPS is way too finicky to have to wait for it before using the basic controls. Update: SERIOUSLY!! HOT GARBAGE. This remote couldn't find a satellite if I stuck one up its... AGH.. and you can't communicate with your dog's collar until it does. FOR THE COLLAR: You won't be happy with the beeper.. It's super quiet. The light is an awesome feature. Vibration may work for your dog, mine doesn't seem to notice it at all. If the antenna was any longer it would pick up signals from outer space. Buy the shorter one if you decide to go with this unit and don't need to keep your dog from crossing an ocean. Seriously though... I'll never buy anything Garmin again. I would recommend you don't either.

Works Great, Use Daily, No Issues
Style: Alpha TT 25
While expensive, this product is rock-solid and has not given me a single issue over 2 years of use. Would buy again, highly satisfied. Can't beat the functionality or peace of mind of knowing right where our beloved family pet and hunting companion is located.

Great little radio, it was.
Great value for the price. I have received excellent audio reports on a couple repeaters I have tested on so far, on the first day with the radio. Love how you can customize all the display background and text colors. Tempature sensing fan works properly. Unfortunately, they do not send a programming cable with this radio, very annoying! It will not save offset and t-ctcs tone into memory mode when programming by hand, which is unfortunate because it is easier to program by hand than some other cheap radios, like the Baofeng keypad. I really wanted to upload all my channels via Chirp, and to make sure Chirp is actually supported before posting review, but it is what it is, and now I have to find a proper programming cable, then hope I did not pick one that does not work. Other than this very disappointing fact, this radio is well worth the money and I highly recommend if you are on a budget or just getting into the hobby. I have mainly been working HF since getting my General ticket and have made contact all over the world, so you can rest assured this review is by someone who knows what they are talking about. Grab one while you can, you will not be disappointed, except for them not including a programming cable! Edit: Have to return, squelch not working on second day. Right in the middle of a net, had to use monitor button to finish my contact. Turn monitor off and the receiver will not open squelch, which is set to 1. Can set squelch to 0 and receive but anyone who runs VHF/UHF knows that, unlike HF, an open squelch is just too noisy. Spent hours trying to fix, no joy! 73, Stephen
