This is definitely the best protein powder I've ever used. I use it because I don't eat meat and it's a supplemental boost of protein for me. I do walk but I don't workout. I don't like any milk products so I mix it with water, coconut water and/or almond milk and it is like a dessert. Lots of good protein and no artificial sweetener! 5 stars!!!

Good Stuff
I used to be all about pro complex, but since those prices jumped i have been unable to find a new protein that i really love. syntha 6 has filled that void, as it is a great product that is also affordable. It's allowed me to put on lean mass without any fat, as i have put on a few pounds of muscle but my body fat is still under 5%. Definitely a good buy

Lean muscle builder? Here it is!
I basically love this product. It really helps with recovery time, good for us that work multiple body parts a day. It also helps pack on lean muscle mass, rather than the carb and water filled muscle that mass gainers provide, which is helpful for people who are into martial arts as heavier arms = less speed. It is definitely good for those that want good, lean, fast twitch muscle!

Great taste and easy on the stomach
Syntha-6 is the first protein powder supplement that did not leave me bloated and gassy. I'm a marathon runner and use this product mainly for recovery as I don't want to build up too much mass. In the future when I attempt triathlons, I'm certain I will maximize the effectiveness of Syntha-6 as it was intended. As a prior poster mentioned, it really helps with recovery and I find that taking one serving within 30 minutes after a workout and another before bedtime on my long-run days has help me recover a day sooner than the other blends on the market. I don't want to mention any names, as each product is effective in its own right. Just experiment and find what works best for you. I am a believer in Syntha-6 and will stick with it until something better comes along. Also, I ordered the chocolate flavored one and found it to taste wonderful. I mix 1 1/2 scoop with .5L (regular bottle water)and found that to have the best consistency for me. When I mix it with milk, it is too thick and creamy. I suggest 1 or 1 1/4 scoop with milk. Another thing I have to mention is that this tub of powder is huge. Couple with the fact that it is red, there is no way you will miss it sitting on the shelf. I think BSN intentionally chose red to ensure that you see it and use it. If they didn't, they got lucky. I think every supplement maker should do this. My wife thinks it's an eyesore against her kitchen decor, but she doesn't mind the effects it has on me. You can't win them all. Finally, this product is fiber-fortified with 5g per scoop. So the recommended 2 scoops will give you 10g. Should you drink the recommended 2-4 servings per day, you'll be quite "regular." I'll just leave it at that. I neglected to notice this when I first started using Syntha-6. In addition with my daily fiber supplements, there were some near misses. Hope this comment helps. Good luck to you all.

great product
Syntha-6 workes great. This product helped me to loose weight and keep it off. Also the protien really helped on the recovery time, you start to feel its affect of the recovery time with in an hour.

my favorite protein powder!
This product is great!! I use it after each workout which is 6 times a week and have already seen great improvement in the 3 weeks I've used it. It is very nutrition, great in value, and extremely tasty! i look forward to using this product in the future.

You get what you pay for
This is my all time favorite protein shake ever! It tastes great (unlike a lot of other brands), and most importantly: it works. I'm 16, I'm able to make consistent gains and add lean muscle mass, without adding fat.

Great Product!!!
Tried this product after using a few other protein blends, Was very surprised how light but filling this product was. I workout 5 times a week and use this daily for recovery and it has held up really well. It mixes well with 12 ounces of water not thick and sugary. Has low sugar concentrations when compared to other blend. So far i have retained lean muscle while losing fat. Give it a try when the cost is low and if you like monitor it as the price varies from [$] to a sale price as low as [$] with gold card. Taste is good that i have a 9 year old son who tries taking it from me and says it taste better than the chocolate milk he usually drinks.

I've tried TONS of protein powders, and this is for sure the best tasting one I've ever had! When you eat nothing but eggs, veggies and chicken all day, this is legit an awesome mid morning and mid afternoon Snack! I also use it after workouts. I've only been using this product for a week so I'm not sure if it enhances muscle gain and recovery.
