This protein powder tastes awesome and has great mix ability! The strawberry tastes awesome. Once it runs out, going to try the chocolate one next. Definitely buy again 👍🏻

Been using protein powder for decades, and typically have digestive issues with most types. Not this one. Smooth, blends easily, great taste with no stringy aftertaste, and easy on the stomach.

Just a bit about myself so you know what kind of body this is going into. I work at a youth camp doing lifeguarding during the summer and various physically strenuous maintenance tasks during the winter. I'm not sure how this would work for someone trying to pack on serious muscle for various competitions, but for me this works great. I use it for two things, to add extra protein to my diet and to add usable calories (as opposed to candy bars and snacks). When not doing the hard labor, I mix one shake serving with two cups of chocolate or strawberry milk (depending on the flavor of the shake and drink it in place of a meal when I don't feel like eating and it gives me enough calories and nutrition to keep my body going. When I am doing hard labor (tree cutting, wood splitting, etc) I use these to supplement my protein intake and add more calories. During times of heavy labor, I'll need around 5,000 to 6,000 calories a day, but I don't usually have the time to stop and have a fourth and fifth meal and these fit the bill perfectly. I do the straight shakes to help me cram more calories into my body and to help me recover with extra protein. The taste is also great; I have both the strawberry shake and the chocolate shake and while you can still tell they are protein shakes, you don't have to force them down like other shakes. I would not choose these over a real milkshake (like some reviewers imply) but they are still really good and satisfy your sweet tooth quite nicely. If you want pure protein, these are probably not the greatest since it has a good dose of carbs and fats, but if you just need more protein in your diet and a few extra calories, you can't go wrong with these. *note- do not drink these before a meal if you have to make sure to get calories from the meal. One shake will curb your appetite and you won't be hungry. Wait until after and slam it down.

I have been weightlifting for a year now, but only recently have I started to get serious. I have lost 40 lbs, but part of my weight-training goal is to gain strength and I certainly wasn't accomplishing this goal through weight-lifting alone. I started to research how to clean up my diet and this brought me around to searching for a protein supplement. After finding several other protein shakes to be distasteful, I was advised to look at Syntha-6. After trying a sample (which is rare enough to find in a GNC) I knew I had found my protein shake. In this month, I have noticed incredible results in strength- it's like my body was completely prepped but lacked the proper building blocks. Positives: Many, but here are some that appealed most to me. -Taste: The strawberry milkshake is fantastic mixed with water (preferably ice cold to simulate an actual milkshake). I have heard and often used the comparison to a McDonald's strawberry milkshake- which is quite a leap above many other protein powders. I thought my sweet-tooth would be a huge handicap in achieving my fitness goals, but this protein shake really feels like I am treating myself after every workout. My 20 oz shaker bottle is usually empty by the time I am leaving the gym parking lot. -The nutritional value in a double serving can serve as a quick meal on-the-go (although I am currently at 6 small meals a day, one of these is usually a protein shake and possibly something small). -Going from a protein bar to Muscle Milk, I found a slight decrease in my recovery time. My first run with Syntha-6, I completed a brutal leg workout that I thought would have me wincing at the mere sight of the stairs in my house the next day. Although I still felt the work-out, I was able to complete my second day of training with some cardio thrown in without issue. Syntha-6 has not let me down yet for improving recovery time. -This was the perfect price for me. After searching other stores (bodybuilding.com, GNC, etc.) I found Amazon to have the best price and with free shipping it was a no-brainer. To give a good idea, using 4 servings daily (early day and post-workout) the 5.04 lb lasted just over a month (roughly 5 weeks). Time to get more! Negatives: The few and far between. -Mixability. I will be the first to admit that this is a rough shake to mix up. With a spoon and a glass it is nearly impossible. I had success with a blender, but I didn't really want to bring a portable electronic blender to the gym. This was a very quick fix however, as I got a blender bottle (recommended to purchase on Amazon or Wal-Mart) with the little wire ball and... Boom. Mixes great, although if the bottle is damp (recently washed) the powder has a tendency to absorb the droplets and congeal to those spots and sometimes mixing those out can be tough. -What to mix with? I recommend ice-cold water, but I did try it with both regular and soy milk. I was REALLY hoping the taste would come through in the soy milk, as it has greater nutritional value than regular milk. That was the only time I had to choke down a syntha-6 shake. In regular milk, it tastes similar to the Nesquik strawberry milk. -Scoop size. I know this is dumb, but the scoop is considerably large. I am going to estimate it to be about 3/4 of a cup (more or less?). I think this is part of the problem that people have with mixing it up. It suggests 8 oz of water per scoop and I have to dilute it a bit more than that... But this also helps get in my daily quota of H2O. Would I recommend this? Definitely.

My favorite protein since 2007. Just be mindful of the ingredients because it might not be the healthiest option. So maybe better to take breaks but this is the best tasting protein EVER. Use milk too, taste just like strawberry milkshakes.

This is a comprehensive review, comparing Dymatize Nutrition Elite Gourmet, Optimum Nutrition 100% Whey Gold Standard, and BSN Syntha-6 Protein Powder, all in strawberry flavor.

I then compared each protein to its counterparts in each category and rated them best (3/3) to worst (1/3).
