Straight-up high-stim fat burner with 300mg caffeine and a solid adrenergic lineup.
Arsynist is a straight-up, high-stim fat burner in capsule form that ramps up energy, kicks adrenergic activity into gear, and sharpens your mind during a cut. This isn't some gentle daily pill. It's a serious stim stack with 300mg caffeine anhydrous, 200mg 2-aminoisoheptane HCl, 50mg synephrine HCl, 50mg higenamine HCl, 50mg hordenine HCl, and 3mg yohimbine HCl, plus some nootropic and absorption helpers. The goal? Hit you with quick nervous system buzz, crank up the heat, and make sticking to low calories easier with better drive, alertness, and hunger control.
At the heart is 300mg caffeine anhydrous – a solid hit that boosts alertness, workout power, and how energized you feel by blocking adenosine and ramping up catecholamines. You'll notice it fast, especially on an empty stomach. L-Tyrosine at 375mg helps make those catecholamines. Studies show tyrosine shines at higher doses, like grams, so this is more of a team player here, working with caffeine and other stims instead of stealing the show.
Vitamin B12 is in at 300mcg as methylcobalamin. That's way over daily needs, but it's not a stim on its own unless you're low on it. Think of it as backup for your metabolism, not the main event.
The heat and adrenergic side is no joke. Synephrine HCl at 50mg is a strong addition that helps burn more energy and curb appetite. Yohimbine HCl at 3mg blocks alpha-2 receptors, which is why cutters love it, especially for fasted cardio. Higenami

Key Highlights
- 300mg caffeine anhydrous in two caps gives you a real stim base. You'll feel more alert, driven to train, and full of energy before cardio or weights, especially on an empty stomach.
- 200mg 2-aminoisoheptane HCl is what makes this thing hit hard. If you're after more than just caffeine vibes, this brings the mood lift, urgency, and workout aggression you want.
- 50mg synephrine HCl is a legit dose for heat and energy burn. It works through adrenergic paths to help with appetite and pairs great with caffeine in stim formulas.
- 3mg yohimbine HCl adds that cutting edge. Its alpha-2 blocking is why folks on fasted cardio or deep cuts grab it for a stronger fat-loss feel.
- Paradoxine® grains of paradise at 15mg is a cool branded ingredient with real studies on boosting energy spend. It's one of the better-backed metabolism boosters here.
- Everything's out in the open on the label – every ingredient and dose. In high-stim burners, that's huge so you know exactly how much caffeine, yohimbine, synephrine, and helpers you're getting, no prop blend guesses.
- L-Tyrosine at 375mg backs up the stim-heavy setup. It's not the big gram doses from studies, but it fits right in for better focus and handling stress with the caffeine stack.
- Vinpocetine at 5mg and Huperzia serrata extract at 300mcg add a focus twist. These aren't massive doses, but they help dial in that sharp, locked-in vibe cutters love.

Who Is This For?
- Competitors on low cals needing workout fire to stay up. 300mg caffeine, 200mg 2-aminoisoheptane, synephrine, and yohimbine fight that flat, drained cut feel with more drive and urgency.

- High-tolerance folks bored with 150-200mg caffeine burners. This layers stim paths plus tyrosine, vinpocetine, and Huperzia serrata for a tougher mindset.
- Dieting pros who use it for gym energy and work focus. Caffeine, 2-aminoisoheptane's DMHA vibe, and nootropics handle tough low-cal days in and out of the gym.
- Advanced lifters picking capsules for easy, exact dosing. Two caps, full formula – great for trips, pre-cardio, or ditching shakers.
- People chasing real heat over mild boosts. Cayenne, Paradoxine® grains of paradise, synephrine, and caffeine give that quick warm-up stim fans know.
How to Use
Try 1 cap first to check tolerance, especially if new to high-stims with yohimbine, synephrine, and 2-aminoisoheptane. If good, go to 2 caps 20-30 minutes before training, cardio, or your big push. Take with 8-12 oz water – don't dry swallow. Hits hardest empty stomach, but light food helps if stims bug your gut. Don't stack with other stim stuff like extra caffeine, synephrine, yohimbine, or pre's unless you're pro at it. Better to pair with non-stims like electrolytes, creatine, or protein. Tolerance builds, so cycle or use on key days, not forever. Keep in cool, dry spot with lid tight – capsules hate moisture and heat.
What to Expect
Minutes 0-10: Capsules mean no taste, but it's calm before the first buzz starts. Minutes 10-20: Caffeine kicks in, alertness climbs, body warms, and you feel more urgent. Minutes 20-40: Full stack hits with 300mg caffeine, 2-aminoisoheptane, synephrine, and others for peak energy and heat. Minutes 40-90: You're in the zone for training or work, with lasting drive and less hunger. After, it fades slow, but stims can hang around hours based on you. Days 1-7: Test your tolerance – no loading needed. Weeks 2-4: It's about how you adjust to the stims, so cycling keeps it fresh.

Frequently Asked Questions
How much caffeine is in Arsynist?
A full serving of Arsynist provides 300mg caffeine anhydrous from 2 capsules. In real-world use, the stimulant effect feels stronger than 300mg alone because the formula also includes 200mg 2-aminoisoheptane HCl, 50mg synephrine HCl, 50mg higenamine HCl, 50mg hordenine HCl, and 3mg yohimbine HCl.
Is Arsynist a beginner-friendly fat burner?
No. This is an advanced high-stim formula with a stacked adrenergic profile, and beginners should not treat it like a mild metabolism support supplement. Starting with 1 capsule is the minimum sensible tolerance check, but many new users are better served by a lower-stim option.
When should I take Arsynist?
Take it 20-30 minutes before fasted cardio, weight training, or the most demanding part of your day. Most users get the strongest onset on a relatively empty stomach, though a light meal can reduce stomach discomfort if you are sensitive.
Can I stack Arsynist with pre-workout?
In most cases, no. Arsynist already delivers 300mg caffeine plus several additional stimulants, so stacking it with a pre-workout can push total stimulation too far. If you want to stack it, keep the add-on non-stimulant, such as creatine, electrolytes, or a pump formula without caffeine.
What does Paradoxine® do in this formula?
Paradoxine® is a branded grains of paradise extract standardized to at least 12.5% 6-paradol, included here at 15mg. It is one of the more evidence-backed thermogenic ingredients in the formula and is used to support energy expenditure and a stronger heat-producing effect.
Is the L-Tyrosine dose in Arsynist clinically dosed?
Not as a standalone tyrosine formula. The research discussed in the ingredient knowledge base often uses gram-level tyrosine intakes, while Arsynist provides 375mg. Here, tyrosine is best understood as a supporting ingredient for the stimulant stack rather than a full clinical nootropic dose on its own.
Does Arsynist use a proprietary blend?
No. One of the formula’s real strengths is full label disclosure, meaning every active ingredient and every dose is printed on the panel. That is especially valuable in a category where proprietary stimulant blends are common.
Will Arsynist suppress appetite?
Many users take formulas like this for exactly that reason. The combination of caffeine, synephrine, yohimbine, and the broader stimulant stack is designed to make cutting more manageable by increasing energy and often reducing the urge to eat.
Can I use Arsynist for fasted cardio?
Yes, that is one of the most obvious use cases for this formula. Its capsule format, 300mg caffeine, 3mg yohimbine HCl, and broader thermogenic architecture make it especially relevant for experienced users who prefer a hard-hitting pre-cardio stimulant.
How often should I use Arsynist?
Because this is a high-stim product, strategic use usually makes more sense than nonstop daily use. Frequent use can build tolerance to the stimulant experience, so many advanced users reserve it for training days, cardio sessions, or the hardest stretch of a cut.
