  • Best Tasting Protein Powder
Flavor Name: Chocolate Milkshake Size: 5 Pound (Pack of 1)
I have used many different protein powders over the last few years and the biggest complaint I have with most powders is the way they taste. Out of the many I had tried for years, I finally had settled on ON Whey Gold and it was OK, but I didn't love it and so I didn't drink it as much as I should have when working out. Also, it did cause gas issues, a common side affect of many protein shakes, and also the aftertaste wasn't bad, but nothing to be happy about either. The price was great on it as well, and so I just settled on it. Finally, after reading reviews about Syntha-6 online and having friends tell me about it, I gave it a shot and it is AMAZING!!!!! I only drink chocolate flavored protein shakes and this one is creamy and rich and so delicious that it doesn't even seem like you are drinking a protein shake. Also, it has 6 different kinds of protein sources, hence the name, and I like that so I get fast and slow digesting proteins at once, which is much better for overall muscle growth. In addition to that, and most important I think, is that it has digestive enzymes and also 5 grams of fiber per scoop. That helps so much in preventing bloating, gas, and even constipation. I know that may gross some people out, but for anyone drinking a few shakes a day, it is very important. The shake is a touch sweeter and I like that as well, and it is a good dessert as well. It has 22 grams of protein per scoop and mixed with 8 oz of milk, a perfect 30 gram shake that can be taken anytime during the day, or multiple times throughout the day. The cons: I wish it had more BCAA's, but from the powder form I buy of that, I know why they don't add extra in and that is because it would make it really chalky. Also, for the protein percent per scoop, it isn't as high as ON Whey or some others, but the mix of proteins compared to just straight whey is a better trade off I think. Pro and Con: The cost is a bit more to a lot more depending on sales and per scoop right now without any sales or coupons or other promos, it about a $1 per scoop where I could get ON Whey at about $0.50 per scoop. So yes, double the price, but when you realize that this is something much more enjoyable and that taste is just as important, than it justifies the cost. At best I could do 2-3 scoops of ON Whey Gold per day for a few weeks, but with this, I easily do double scoops after workouts and before bed, and another scoop upon waking and another as a snack, so about 6 scoops a day without ever getting tired of it. That is 180 grams of protein, plus 30 grams of fiber. I usually don't get that much fiber from my mostly meat diet otherwise, and as someone trying to get 250-300 grams of protein a day, this has helped out so much. Even if your just looking for a shake in the morning for breakfast, this is great as it has about 200 calories and when mixed with milk and then a piece of fruit or a small granola bar or other breakfast item, it is a great 400-500 calorie meal that is better than any fast food pickup you can make. I already recommend this to so many of my friends, and I will do the same for you as well ***** Bonus Points ********** I wanted to try different flavors of Syntha-6 and wanted to order trial kits of different flavors to try before buying a whole jug, and the flavors I wanted were out of stock at the time and so I emailed BSN. Within an hour, they responded, asked for my address and sent me a Cookie Dough and Chocolate Cake batter trial packet for free. They were apologetic for not having what I wanted in stock and thanked me for my business still and the two trial packets they sent were not asked for by me, yet delivered for free and I can say it is a joy to deal with great customer service. GO BSN!!!!!!! ... show more

  • Talk about taste! DAAAAANG!
Flavor Name: Chocolate Milkshake Size: 5 Pound (Pack of 1)
Please feel free to read the hundreds of other reviews on this product, as they will provide you with invaluable information. However, it good to note that this product comes with Branched-chain amino acids, Glutamine peptides, is Aspartame free and stacks with a bunch of supplements. For the record however, I am going to voice my opinion solely on flavor in contrast to MYOFUSION Vanilla flavor. To be fair, I got MYOFUSION's vanilla flavor because I read the rather decrepit reviews of the other flavors. Being a college student and investing in 5 lb tubs every month means you better LOVE the flavor that you end up picking (however to GNC's credit, they do offer a 30 day trial and return period). In all honesty, the vanilla flavor was pretty decent. MYOFUSION lacks the aforementioned BCAA's, and from what I recall, each scoop is about 36g/ serving. Its good and flavor wise beat out GNC's generic whey protein, or even Warrior whey. So I read up reviews about BSN Syntha 6 and was shocked about how many positive reviews it got; specifically the chocolate version. Needless to say once I ran out of MYOFUSION, I quickly ordered Syntha-6. I received the item today, and couldn't wait to try it out (even though today is an 'off' day for me). Based solely on flavor and taste alone, I CANNOT stress how amazing it is with just a dash of 1% skim milk (less than half a cup). I mean it truly tastes like Chocolate milk. There is a creamy like texture, but not too thick (also depends on how much fluids you add obviously). Each heaping scoop is a mighty 44g (22g protein, 15g carbs, 2g sat fat, 2g sugars) and equates to 200 calories per! So be careful and make sure all your nutrient intake numbers play well with your goals; please read other reviews as well, and be sure to look at the product snapshot to get a gauge of the nutrients packed into this monster. I look forward to trying BSN for this whole month and seeing for any positive results when it comes to weight training. This thing is packed to the brim with nutrition and flavor; I cannot see why anyone would ignore this if you have a remote and passing interest in physical activity. For roughly $42, I can't imagine something that meets my nutrient requirements, balances cost, and doesn't skimp on the taste. AMAZING! p.s. This and the Blenderball (for mixing) are a marriage made in heaven! ... show more

  • Great protein, great price, great results!
Flavor Name: Chocolate Milkshake Size: 5 Pound (Pack of 1)
I don't need to tell you that Syntha-6 products are good products. They really know how to market their products, and the product reviews reflect excellent results. Here are my impressions on having used Syntha-6 over the past 2 years. I moved to Brazil 3 1/2 years ago, and there, popular name brand supplement prices are insane. The price for this product there is more than double on some occasions, so it wasn't really feasible for me to keep buying it. At this price, it was a no brainer. Seeing as how i came home every year, I decided to stock up and take some with me and here are my results. I tried to intake just two shakes a day. The carb count is pretty high on these, but as I go hard in the gym, I really need that extra boost. If you take this protein, and don't work out - you will gain weight. That's not rocket science. However, like I said, burn those carbs up in the gym! That's what they're for! Compared to other proteins, I always have a big boost in the gym with this one. It is probably because this isn't just strictly protein. There are lots of good things in this for you, so don't be surprised if you notice a great improvement in energy and overall ability. The taste is awesome too! I always get any variety of chocolate, and it's a great treat throughout the day. Unlike some proteins, this protein mixes exceptionally well. No issues whatsoever. One negative I found with this is the digestibility. I'm sure this is different for different people, but I maintain a little stomach trouble with this product. Not enough to stop me from using it, but enough to be annoying. I do have a sensitive stomach though, so I'm sure it won't have the same effect on everybody as it does me. Overall I really enjoy this product. I want to try the isolate out, but it's a little pricey for me right now. Amazon has a great price on this, and after seeing how much it is in Brazil, I'm glad to know I can find it here at this great price. Go and try it for yourself! After you get the boost, you'll be glad! ... show more
