300mg caffeine plus classic yohimbe for that real OG pre-workout fire
BPI Sports 1.M.R The OG Formula is a throwback high-stim pre-workout that's all about cranking up your training energy, not some fancy transparent setup. It hits hard on your nervous system with 300mg caffeine anhydrous, adds extra kick from yohimbe bark extract and cocoa's methylxanthines, then smooths it out with brain-boosting stuff like CDP-choline, GABA, taurine, and glycine. This isn't your pump-heavy option—it's old-school focus and drive that gets you amped before you even start lifting.
The star here is 300mg caffeine anhydrous. That's a solid, high dose that ramps up alertness, energy, reaction time, and workout motivation quick. Being anhydrous means it kicks in fast and hits sharp, not slow and steady. Niacin comes in at 25mg as nicotinic acid. That's way under the big doses for cholesterol stuff, so it's here for energy support through NAD/NADP paths and that warm flush feeling some folks love in pre-workouts.
CDP-choline stands out. It's a choline source that helps make acetylcholine, which boosts focus, muscle control, and that mind-muscle link. It also aids brain cell health as a phospholipid builder. Downside? No dose listed, so you can't check if it's at a useful level. Still, teaming it with caffeine is smart—caffeine amps you up, and choline channels it better.
Taurine adds another smart layer. Taur
Key Highlights
- 300mg caffeine anhydrous — packs a punch for quick alertness, drive, and gym readiness. The anhydrous form means it hits faster and harder than slower caffeine types, making it the heart of this formula's instant boost.
- 25mg niacin as nicotinic acid — gives that familiar warm flush for some while helping with energy production via NAD/NADP. Not a huge dose, but it adds to the 'it's working' vibe old formulas nailed.
- Yohimbe bark extract thrown in — screams high-stim for vets. It ramps up that fired-up, sweaty feel and aggressive edge, especially if you're training on an empty stomach.
- CDP-choline brings real brain power — helps build acetylcholine for better focus, movement, and connecting with your muscles. Turns caffeine's buzz into something more targeted, not just wired.
- Taurine keeps things steady in muscles and nerves — this amino acid handles cell water and calcium in muscles, plus calms the brain a bit. In a stim-heavy mix, it smooths out the rough spots from straight caffeine.
- L-carnitine tartrate and gamma-butyrobetaine team up for fat-burning vibes — carnitine moves fats into cells for energy, and gamma-butyrobetaine backs it up, perfect for those sweaty, cutting-style workouts.
- Cocoa does more than taste good — it's got methylxanthines like theobromine for a smoother energy and mood lift with caffeine. Makes the whole stim feel more rounded, not just a caffeine slam.
- GABA and glycine add a chill twist for a pre-workout. They're usually for winding down, but here they balance the stim rush, cutting down on that overly jittery edge from stacked energizers.
Who Is This For?
- Seasoned lifters who handle high-stims and want quick, bold energy for heavy days. 300mg caffeine with yohimbe and cocoa gets you fired up fast.
- Cutters in a deficit needing intensity when calories are low. Stim mix, caffeine's hunger edge, and L-carnitine tartrate help keep sessions strong while dropping weight.
- Afternoon trainers after a mental workday wanting more than buzz. Caffeine and CDP-choline boost alertness and focus for better workouts.
- High-intensity folks picking old-school energy over pumps. If sweat, aggression, and feel beat nitric oxide lists, this fits.
- Guys where plain caffeine falls flat. Taurine, GABA, glycine, cocoa, and choline layer it up for more depth.
- Athletes training fasted wanting thermogenic dial-in. Yohimbe shines here but needs care.
How to Use
Try half a scoop first, especially if yohimbe's new or 300mg caffeine is your max. Take 20-30 minutes pre-workout for caffeine to ramp up during warm-ups. Mix in 8-12 oz cold water, shake well—more water tones down flavor but not the kick. If fasted, yohimbe might feel rougher, so snack 60-90 minutes before. Don't add coffee, drinks, or yohimbe stuff unless you're pro at stim loads. Pair with non-stim basics like creatine or carbs. Cycle in low days to fight tolerance. Store sealed, cool, dry—no humidity to clump it.
What to Expect
0-10 minutes: Might just taste it, feeling like you took something strong. 10-20 minutes: Caffeine kicks in, niacin could flush, yohimbe sharpens the edge. 20-40 minutes: Peak time—alert, urgent, aggressive, with CDP-choline focusing your head. 40-90 minutes: Energy holds, but depends on your tolerance to yohimbe. Days 1-7: It's all about that per-dose feel, no big buildup. Weeks 2-4: You might get used to the stims, so save it for big sessions to keep it hitting hard.
Frequently Asked Questions
How much caffeine is in BPI Sports 1.M.R The OG Formula?
This formula provides 300mg caffeine anhydrous per serving. That is a high-stim dose on its own, and the total perceived intensity is amplified by yohimbe bark extract and cocoa-derived methylxanthines.
Is 1.M.R The OG Formula a beginner-friendly pre-workout?
No. With 300mg caffeine plus yohimbe, this is much better suited to experienced pre-workout users who already know they tolerate aggressive stimulant formulas well.
What makes this feel stronger than a regular caffeine pre-workout?
The formula does not rely on caffeine alone. Yohimbe bark extract increases sympathetic stimulation, cocoa contributes additional stimulant alkaloids like theobromine, and CDP-choline adds a focused nootropic edge, creating a more layered and intense experience.
Why is CDP-choline included in this pre-workout?
CDP-choline, also called citicoline, is a choline donor that supports acetylcholine synthesis. In practical terms, it is included to help turn raw stimulant energy into better concentration, motor drive, and mind-muscle connection.
Does this product have fully disclosed ingredient doses?
No. Niacin at 25mg and caffeine anhydrous at 300mg are disclosed, but several other actives including GABA, L-carnitine tartrate, cocoa, yohimbe, CDP-choline, taurine, glycine, and inosine are listed without exact amounts. That means you can feel the formula, but you cannot fully verify dose adequacy for every ingredient.
Should I take 1.M.R The OG Formula with food or on an empty stomach?
Most users do best taking it 20-30 minutes before training, with or without a light meal depending on tolerance. If you are sensitive to stimulants or yohimbe, taking it fully fasted can make it feel significantly stronger and rougher.
Can I stack this with coffee or a fat burner?
That is generally not a good idea unless you are extremely experienced and deliberately tracking total stimulant intake. With 300mg caffeine plus yohimbe already in the formula, stacking additional stimulants can push heart rate, anxiety, and crash risk much higher.
What will I actually feel from niacin in this formula?
At 25mg as nicotinic acid, some users may notice warmth, skin flushing, or a tingling heat effect shortly after taking it. That sensation is not the main performance driver of the formula, but it does contribute to the classic old-school pre-workout onset feel.
Is this a good pre-workout for cutting?
Yes, for the right user. The high-stim profile, yohimbe inclusion, and L-carnitine/gamma-butyrobetaine positioning make it especially appealing to experienced lifters training in a calorie deficit who want more urgency and thermogenic feel.
How does this compare to more modern transparent pre-workouts?
Modern premium formulas often fully disclose every active and emphasize clinically dosed pump, endurance, and focus ingredients. 1.M.R The OG Formula instead follows a legacy high-stim approach: strong immediate energy and intensity, but less dose transparency across much of the label.
