Making the connection between your muscles & your mind*

If you look at the concentrated pre-workout landscape today, more and more companies are resorting to larger dosages of caffeine in smaller scoop sizes to compensate for the lack of R&D into improving an athlete’s performance during exercise. Everyone pitches ‘more pumps, more energy, and more endurance but what does that truly mean in an era when so many concentrates fail to perform? D-Stunner™ seeks to support razor sharp focus and mental clarity and the energy rush necessary to take your weightlifting experience to the next level.*

Choline vs Aplha GPC

Common delivery forms of choline fail to deliver choline to the body as efficiently as Alpha GPC (Alpha-glycerophosphocholine) which makes it the choline delivery method of choice for supporting normal cognitive function. It is also known to be a precursor to acetylcholine in the brain (neurotransmitter). In short, this makes Alpha GPC an ideal Choline supplement for supporting the ‘mind to muscle’ connection during exercise.*

"Common delivery forms of choline fail to deliver choline to the body as efficiently as Alpha GPC...*"

Alpha GPC and Huperzine A

A limiting factor for acetylcholine in the body is acetylcholinesterase. It is an enzyme that works to breakdown acetylcholine and regulate its activity. Huperzine A is a naturally occurring compound from Huperzia serrata (toothed clubmoss) that acts as a acetylcholinesterase inhibitor. So it may support the activity of Alpha GPC.*

Worst pre-workout I have ever used. I had high hopes for this product but unfortunately, I didn't catch any energy or focus from this. The taste was just as bad. Maybe this could work well for someone else, but certainly not me.

This was a great PWO all around. In particular, I appreciated the energy boost that it gave me. Even on the most difficult workouts, I always seemed to have the necessary energy to get through the tough sets. Most of the time, this was coupled with a serious mental intensity/eagerness to get in there and hit the weights. While taking this PWO, I made noticeable progress on several lifts on which I had been having a hard time progressing. My working weight on bench press went up 10 pounds in about one month, when I finally hit 3x5 on a weight I had been struggling to get, added 5 pounds, and then just a few weeks later, I hit 3x5 on that too. I never crashed while taking this, the energy always just sort of gradually tapered off in the hours after the workout. The Lemon Drop flavor delivered the goods, tasted just like you would want a lemon drop-flavored product to taste, except I had to use 12 ounces of water instead of the package directed 10 ounces, because 10 was a bit too strong for my liking. All around a very strong value for the price, at $30.99 for 25 servings. This is a product I would gladly purchase and have no qualms about recommending to others looking for that extra boost.

Betancourt D-Stunner is a creatine free preworkout that delivers the dmaa quality effect without the dmaa or crazy high caffeine content. Containing 300mg of caffeine per serving, this is a pwo that will not leave you jittery or ill feeling as a result of too much caffeine. The taste, in Lemon is absolutely outstanding, just like a candy lemon drop. Nothing I would change here, unless they can get the same taste with stevia or other natural sweetener. The fact that this is creatine free is a bonus, for me at least, as I only take creatine HCL because of the gastro issues like bloating and gas I experience with mono, so I can simply take a scoop of my usual creatine along with this product. I felt no ill effects from this product at all, it was very clean and easy. Mixability is complete and doesn't leave any little lingering particles floating around that I could tell. The effect of this is great. The harder you work out the more the effect comes in, kinda sneaking up on you. At first, it sort of hits you with the energy caffeine, but the focus and mood doesn't come into play until you're sweating it out during a workout, then bam! It's right there where and when you need it most. Overall I really liked this product and would definitely keep it in my list of go to pre workouts.

Recently completed use of a 25 serving tub of Betancourt's concentrated stim pre-workout, D-Stunner Alpha. It is definitely a pre-workout that prioritizes energy and focus. It has intensity and help you push through heavy workouts. Check out my thoughts: This pre-workout is clearly designed and market as a concentrated stimulant - it will be thus judged as one. It is composed of two proprietary blends: Alpha Endurance Blend and Alpha Energy & Focus. I prefer transparent formula, but for a concentrated stim proprietary blends are easier to look passed especially when the caffeine content is disclosed. This is the case for D-Stunner Alpha - one serving contains 300 mg of caffeine total. The Alpha Endurance Blend has 3.3 grams of Betaine Anhydrous, CarnoSyn Beta-Alanine, Malic Acid, AgmaPure Fermented Agmatine Sulfate. The Alpha Energy & Focus has 755.7 mg of Alpha GPC (L-Alpha-Glyceryl Phosphoryl Choline), Caffeine Anhydrous, N-Methyl-L-Tyramine HCI, Infinergy™ Dicaffeine Malate, Rauwolfia Vomitoria (Rauwolscine 90%), Huperzia Serrata extract (std to 1% Huperzine A). Although the formula is proprietary, I do like what appears to be a solid dose of Alpha GPC (looks to be equal to 300 mg) and the nice combination of stims and nootropics. This is definitely a formula with some intensity! I put the formula at an 8.5/10 at its current price of $1.24 per serving. This is a just little high for a small scoop product even with that massive Alpha-GPC dose. Would love to see it closer to $1 per serving. During my use of D-Stunner Alpha, I was definitely impressed with the focus and energy dimensions. The alpha-GPC and two forms of caffeine really carry the product while the tyramine and Rauwolfia give it an intensity edge. It isn't a pre for hypertrophy workouts or "pump sessions," it is a pre-workout to get your CNS amped up for a heavy session. I found it was a great pre-workout for leg days. You don't have to worry about leg pumps. The alpha-GPC in the formula seems to help blunt any crashes, easing the come down from the stimulant profile, which is intense but not ridiculous. I found D-Stunner Alpha to be great for keeping my CNS keyed in during heavy lifts and improve my physical performance. I put the effects at 9/10. The cherry ice flavor is definitely enjoyable. It has a little tartness to it, and the cherry comes through well. It a little more mild as a flavor that expected but that's cool with me. The product mixes well and is without artificial coloring. I put the flavor at a 8.5/10. I put D-Stunner Alpha at an 8.5/10 overall.

After using this product for the first 3 days I notice how good my workouts improved by giving me more focus and energy than by just drinking some amino acids and caffeine. A top notch product that delivers the hype advertise. I would gladly used it again and most defiantly recommend it to everyone looking improve and make the most gains at the gym or any other athletic activity like soccer, basketball, etc... 10 out of 10.

Love this pre-workout. No need to take several scoops to feel the effects which is what I was forced to do with other pre-workouts. The focus I have after this kicks in is awesome and the increase in my energy levels are huge. The taste is spot on and it mixes great too. Another solid product from Betancourt.

Great product if your looking for sharp focus and energy ! I like to use d-stunner after a long tiring day of work and I need some extra energy to optimize my training routine. Definitely one scoop is all you need or less! Taste excellent also!

This stuff gave me insane pumps, to the point where blood rushed out of my groin. Pretty hardcore pre-workout. P.S. if you don't want your genitals being sucked into your gut, as a result of improved bloodflow, this product is not for you.

I gotta say, I am a fan of Betancourt and their products, B-Nox is always a go to pre workout for me but in all honesty, they dropped the ball big time on this one. This pre workout had to be one of the worst i have used. Barely maintained a pump and i hardly could break a sweat. I really felt no effects what so ever. I guess its supposed to give you really great focus but what i felt was almost a zone out feeling. It made me feel pretty awful halfway through my training session as in my stomach felt odd (which could be different for someone else) and my energy levels kinda dropped. On top of that it tasted quite bad. Im pretty disappointed in this and i cannot say i would recommend it to anyone. I have faith that Betancourt can forsure fix this and come out with something better like everything else they make!

I ordered this product after hearing very good things about it. I have used other Betancourt products previously and was happy so I figured I would give this a try. This was by far the very worst pre workout supplement that I have ever used. Absolutely zero pump or increase in energy and it literally tastes like cough syrup. It also had a great ability to wreak absolute havoc on my stomach to the point that I threw it away. I have used other brands of pre workout supplements and have had poor experiences but I was very disappointed in Betancourts product. I would steer clear of this product as there are better options at similar price points. Lesson learned. Betancourt lost a customer on this product.
