250mg caffeine, DMHA, yohimbine, and ProGBB in one capsule
Dark Labs Ripper is a straight-up high-stim thermogenic capsule that's all about making you feel that quick jump in energy burn, focus, and body warmth. This isn't some mild metabolism pill acting tough. It's a fully open-label stim fat burner for folks who've used this kind before, packing CNS stimulation—that's central nervous system kick—adrenergic activation, and heat support in one dose.
The core is dual caffeine: 200mg anhydrous for that solid alert buzz, plus 100mg caffeine citrate adding up to 250mg total. Anhydrous gives you steady drive and workout readiness. Caffeine citrate hits faster, so you feel it quick. Science-wise, caffeine is the star for fat loss here, proven to boost alertness, performance, heat production, and fat release.
It ramps up from there. 2-Aminoisoheptane at 175mg is a solid dose in today's strong supps. Human studies are thin, which is worth noting; most info is from reviews, not big trials. But users feel it as a potent stim, similar to other intense compounds. In real life, it's what gives that locked-in, no-hunger vibe in tough burners. Bottom line: it's about the feel, not tons of research like caffeine has.
N-Phenethyl Dimethylamine Citrate at 100mg adds mood lift, drive, and sharp focus. This type of amine amps up motivation and that good-feel edge.
Dark Labs Ripper by Dark Labs contains 200mg Caffeine Anhydrous, a clinical dose for training performance and pump.
Key Highlights
- 250mg total caffeine from two sources — 200mg anhydrous plus 100mg caffeine citrate for 250mg active caffeine. This setup gives you strong base energy and a faster kick than single-source caffeine pills.
- 175mg 2-Aminoisoheptane — a big stim dose for that intense, urgent feel pros go after. Human proof is light, so it's more about the real-world punch than heavy science, and we're straight up about that.
- 100mg N-Phenethyl Dimethylamine Citrate — here to boost mood, focus, and drive. It takes the energy past basic wake-up to a fired-up mindset great for cuts and tough lifts.
- 50mg Synephrine HCl — a good hit in a thermogenic pill. It helps crank metabolism and curb hunger, especially with caffeine in stim-heavy burners.
- 5mg Yohimbine HCl — that's no joke dose. It really amps the feel, especially fasted, where you notice better fat support and sharper stim edge.
- 1mg Rauwolfia vomitoria extract standardized to 90% alpha-yohimbine HCl — small on paper, but it packs a punch for sharpness. Alpha-yohimbine feels more intense than regular, so even 1mg matters to vets.
- 25mg ProGBB — added to boost the heat side without more stims. Folks often feel warmer and sweat more, making this a legit thermogenic, not just caffeine in a cap.
- Fully disclosed label — every key ingredient and dose listed. In a world of hidden blends, this transparency lets you see the real mg instead of hype.

Who Is This For?
- Vets doing morning fasted cardio who want a strong stim boost without powder hassle. 250mg caffeine, 5mg yohimbine HCl, and 1mg rauwolfia alpha-yohimbine hit for urgency, heat, and hunger control in fat-loss sessions.
- Pro gym rats in deficits where drive drops as fat falls. Ripper fights that with aggressive stims like caffeine, DMHA, synephrine, and phenethylamine focus.
- Folks who handle yohimbine and crave that sharp feel. 5mg yohimbine HCl plus alpha-yohimbine isn't weak—it's core to the vibe.
- Cap users needing quick thermogenic for cardio, lifts, or work. Dual caffeine means fast start without scoops.
- Lean-focused athletes prioritizing energy, hunger kill, heat over pumps or endurance. Stim-first burner, no extras like citrulline.
- High-stim pre vets wanting underground-style thermogenic cap. 175mg DMHA and layered stims bring intensity when basics feel weak.
How to Use
Start with 1 cap to check tolerance, even if caffeine's your thing. It's not just 250mg caffeine—adds DMHA, synephrine, yohimbine HCl, rauwolfia alpha-yohimbine, and ProGBB, so it can hit way harder. Take 20-30 minutes before workouts, cardio, or tough tasks. That lines up with dual caffeine for build-up before you go.
Down with water, empty stomach best for quick hit, or light food if needed. Big meals slow it down, especially for fasted sessions. Skip stacking with other high-stims or coffee unless planning total load. Creatine, electrolytes, pumps stack fine since Ripper's all about fat burn. Tolerance builds fast, so save for hard days or cut peaks. Store cool and dry to keep caps good.
What to Expect
Minutes 0-10: not wild yet, but you know it's in—some feel early mental sharpness from fast caffeine citrate. Minutes 10-20: energy ramps fast, alertness up, hunger down; sensitives notice stim edge starting. Minutes 20-40: peak time, with caffeine, DMHA, synephrine, yohimbine, and phenethylamine giving focused, urgent heat. Minutes 40-90: stays high, shifting to steady buzz with more warmth and sweat from ProGBB.
Days 1-7: mostly about figuring tolerance, no build-up needed. Weeks 2-4: no loading ingredients, so it's about smart use to keep the kick strong, not daily grinding.

Frequently Asked Questions
How much caffeine is in Dark Labs Ripper per capsule?
Each capsule provides 200mg caffeine anhydrous plus 100mg caffeine citrate, yielding 250mg total caffeine. The anhydrous form gives the formula its strong base stimulation, while the citrate form contributes to a quicker-feeling onset.
Is Dark Labs Ripper a beginner fat burner?
No. With 250mg total caffeine, 175mg DMHA, 50mg synephrine HCl, 5mg yohimbine HCl, and rauwolfia-derived alpha-yohimbine, this is firmly an advanced-user thermogenic.
What does the 175mg of 2-Aminoisoheptane do in this formula?
2-Aminoisoheptane, often referred to as DMHA, is included for a stronger stimulant-style feel—more urgency, more drive, and a harder mental edge than caffeine alone. Human safety and efficacy data are limited compared with caffeine, so its value here is primarily the subjective experience it creates in high-stim users.
Can I take Ripper before fasted cardio?
Yes, that is one of the most natural use cases for this formula. The combination of caffeine, yohimbine HCl, alpha-yohimbine, synephrine, and ProGBB is especially aligned with users seeking aggressive thermogenic support and appetite suppression before morning cardio.
Why does Ripper feel hotter than a normal caffeine capsule?
A major reason is ProGBB at 25mg, which is commonly used to increase the physical sensation of thermogenesis, including body heat and sweating. The stacked stimulants then reinforce that feeling by driving a more activated overall state.
Should I stack Ripper with pre-workout?
Usually no, at least not with another high-stim pre-workout. Ripper already contains a heavy stimulant profile, so if you do stack it, it is safer to pair it with non-stimulant products like creatine, electrolytes, or a pump formula rather than additional caffeine or yohimbine.
Will Ripper suppress appetite?
Many users buy formulas like this specifically for that effect. Caffeine, DMHA, synephrine, and yohimbine all contribute to the appetite-blunting, "too dialed in to snack" feel that is common with aggressive stimulant thermogenics.
How quickly does Ripper kick in?
Most users notice the first effects within 15-30 minutes. The inclusion of caffeine citrate alongside anhydrous caffeine helps give the formula a faster, more immediate rise than a basic single-source caffeine capsule.
Does Ripper contain a proprietary blend?
No. This is a fully disclosed label, which is a major advantage in the high-stim thermogenic category because it lets you evaluate every active ingredient and dose directly.
Is Ripper suitable for late-night training?
No for most users. The total stimulant load is substantial, and between caffeine, DMHA, synephrine, yohimbine, and alpha-yohimbine, sleep disruption is a very real possibility if taken too late in the day.
