MRMNutrition Driven Pre-Workout Powder | Mixed Berry Flavored | 125mg Caffeine | Pure Ingredients| Muscle + Hydration + Energy Blends | Performance Energy | Vegan + Gluten-Free | 29 Servings

This is one of my favorite prework out supplements. I have been using MRM products and this preworkout in particular for years now. Despite what other reviews may think, I think the taste is not bad and the consistency is good. I have taken a lot of workout products and a very avid workout person. If you are not use to supplements, it may take a little time getting use to the taste and consistency but I will tell you this one is better than a lot of other ones I have tried. The biggest reason I take this pre workout over others is because it doesn't have any artificial ingredients including artificial sugar. Artificial sugars are a big ingredient in most workout supplements which drives me crazy! There is evidence of how bad they are for your health yet they are being added to these supplements that are supposed to be used to better your health through exercise.Pros:Price - price is very reasonable for a pre workout supplementTaste - a pleasant taste and good consistency though it may take a little getting use to if you are new to workout supplementsQuality - no artificial sweeteners which is a BIG PLUS! If you are trying to be healthy through exercise but taking workout supplements with artificial sweeteners than you are being counterproductiveEfficient - good clean energy without feeling jittery (this is something that is hard to find with a pre workout supplement, most will make you feel extra jittery or you get a big niacin flush (that skin crawling feeling)) I haven't had this happen much with this supplement. I am only 115lbs and take the recommended dosage and I just get a light niacin flush but a lot of focus and energy to power through my high demand workouts.

I really like this pre-workout. I haven't gotten the chance to try too many pre-workouts without artificial sweeteners, but I've tried tons that did have stuff like Acesulfame Potassium, Sucralose, etc. This one, along with "Honey Badger" are great if you're looking for something without the artificial stuff. The sweeteners used in here are ones like sugar and Stevia leaf extract (Stevia actually has benefits on it's own). I would give this pre-workout a taste of maybe 3.5 out of 5, maybe almost a 4 (depending on my mood for the taste). It doesn't taste the greatest but I really don't mind it much either. I'm not exactly drinking it for taste though anyway.It has a lot of ingredients I look for in a pre-workout: B-vitamins, Electrolytes (good for hydration), Arginine (contains a good bio-available form called AAKG), Creatine Monohydrate, Beta-Alanine, Citrulline (Amino like Arginine, has synergy with Arginine), Betaine, N-Acetyl-L-Tyrosine (Another amino acid - precursor to Dopamine), Caffeine, and other ingredients. It may not work for everybody and may not taste great to everyone, but if you're looking for a pre-workout that's natural and doesn't contain anything artifical, I would give this one a try at least once. It feels much cleaner, in my opinion, than pre-workouts that contain stuff like Sucralose and then also usually have way too much caffeine and stimulants in them. I'm prone to anxiety and the jitters sometimes, but with Driven, the effects are always clean and smooth. For reference, there is about 125 mg. of caffeine in each serving. If a person truly wanted, they could take two servings (even the label says 1-2 scoops is fine).

Good, almost great - I love this product. This is a staple in my supplementation and will continue to be. The flavor tastes great (you have to be used to Stevia). I love the added vitamins and minerals. I do have a few hangs up on this product that I will address. As a 2 scoop user it bugs me it does not come in a larger serving size. I also am bummed at 2 scoops this product only contains - 1.2g of Betaine, 2.2g of Creatine and 2g of Beta Alanine. Why not ditch the AAKG and Citrulline (which is a great supplement, but at 500mg/1g is probably ineffective and is a costly addictive) and up the Betaine, Creatine and Beta Alanine dosages? I would also love to see Alpha GPC (300mg/scoop) added to this product - ditch the Peak ATP (research shows 400mg is the effective dosing of this product). All in all this is a solid preworkout that is completely natural - plus I enjoy picking this up at Sprouts Farmer Market when possible, although their pricing is a tad higher than Amazon.

I've gone to the bodybuilding shows and tried nearly every manufacturer's pre-workout sample packets and after months of trying many, this is the one I found and plan to stick with. 98% of all other company's don't put a thought into sweetening their product, they will not only toss one artificial sweetener, most of them have two, some can even have three. Is that really necessary? Anyway, my reasons for using and supporting this product and manufacturer are these:1) Does the job of a pre-workout well, enhances energy, stamina, and boosts strength2) Only uses proven ingredients, not some huge laundry list of everything that could 'possibly' work like other company's do3) Uses natural sweeteners, at the end of the day I'd rather have my supplement stash consist of natural ingredients rather than every single one of them containing sucralose, ace-k, and aspartame.4) Price, most pre-workouts for a month supply is upwards of $30 or more, this...around $15-20
