Betancourt D-Stunner was actually the first pre workout supplement I ever tried, so I have a bit of a soft spot for it. I think it has a great stimulant blend – I get a good pump without my heart rate going crazy and also get a good energy boost without any real crash. Unless I take too much, in which case I notice a little bit of irritability. But relative to other pre workout drinks it’s barely noticeable.

D-Stunner Ingredients

D-Stunner contains the basic ingredients that are fundamental to pre workout supplements; Beta-alanine, Creatine Monohydrate and GlycoCarn. The GlycoCarn is basically a Nitric Oxide supplement which, while there is a fair amount of conjecture and squabbling in forums, is said to aid in the production of N.O. in muscles. Here is a link to a youtube promotional video for GlycoCarn, and here are some people arguing about it in a forum, if that’s your thing 😉 The best thing about D-Stunner in my mind is the stimulant blend though. I don’t know enough about the biochemistry of what’s going on to explain it; all I know is that it makes me feel happy and amped to hit the gym. More importantly though, I do not notice any significant crash-like effects afterwards, which in my experience I would expect from a central nervous system boost like the one you get from D-Stunner.

Betancourt D-Stunner Review Summary

Pros: Great stimulant blend, no crash.

Cons: Not the best taste, quite bitter.

Energy: Plenty of energy with no noticeable crash.

Pump: Good pump without a crazy heart rate.

Duration: 1-2 hours.

Price: Mid range

Final Word

I like to use this on days that I am resistance training at the gym and have to do something straight afterwards. I get a great pump from this one, heaps of energy and the thing I like best is that there’s no crash so I can go and do whatever it is (usually work) without feeling irritable and blah.

Update: D-Stunner has been well and truly superseded by newer and arguably better products. In my mind Bullnox is a much better product that gives all the benefits of D-Stunner as well as a whole lot more. Check out my Bullnox Review here.
