Syntha 6 Review - 6 Things You Need to Know


Many dieters are looking for a decent protein powder. Let’s see if Syntha 6 is one of the good ones. We dug into the side effects, ingredients, customer service and clinical research. From there we read tons of user experiences. Then, we summarized and refined to give you the bottom line.

Syntha 6 Readers: Click here to find out why we're giving away samples of our product, Boost.

What is Syntha 6?

Firstly, Syntha 6 protein is a supplement that contains various milk-based proteins, egg albumen, MCT powder, Aminogen, papain and artificial sweeteners. One serving is a scoop and that supplies 200 calories, but only 22 grams of protein. It is supposed to support overall nutrition and recovery. If you have a shaker cup, throw it in there to take on the go.

BSN, the maker of Syntha 6, has been around since 2001. The official website tells the visitor where they can buy the product, but it is not available directly from the company. We like that some users rave about the taste and it does provide a decent amount of protein, but read on…

Mixed Results – “Not Everyone Seeing the Same Thing?”

Our first problem to consider with Syntha 6 ingredients is effectiveness. “When reviewing a product, we look at user comments,” says our Research Editor. “With this one, customers are on both sides of the debate.”

“Only from last month I started using Syntha-6. It does not help me with recovery at all,” explained one buyer.

One more shared, “It makes my stomach hurt and I certainly don’t see any difference in my muscles.”

Opposite feelings are also found in customer reviews.

As one comment said, “My muscles have definitely felt fuller since I’ve started drinking this regularly.”

Still another offered, “You can actually see a lean increase for muscle. It takes about a month and a half and with proper training.”

Syntha 6 Taste – “Good, Bad, In the Middle?”

You have to be able to stomach a product like Syntha 6 protein. For some users, that’s just not what happened.

“When that stuff hit my tongue it did NOT taste like cookies and cream,” offered someone who used the product.

“The taste is almost sour in my opinion and it truly took some coercing to drink the entire serving,” said another.

The word “outstanding” came up in some reviews on taste.

As one user put it, “I’ve had every flavor, and all of them are outstanding.”

“Very high quality protein that tastes great,” was one more response.

During years of research, we’ve found a connection between small things, like poor taste, and a cut in your chances of long-term success. If Syntha 6 reviews are accurate and it doesn’t offer what the customer expects, there are hundreds of other similar products out there to choose from.

The Science – “Justified?”

We’re not sure what the customer is looking for from science with Syntha 6. Protein is a huge part of muscle growth and it can help curb appetite. However, this formula is a little calorie-heavy for the average dieter. Especially when you take into account you can find fewer calories in a product with more protein.

What Users Are Saying

"This is a great tasting protein. I’ve probably tried 5 different brands of protein and this tastes the best for me. Even the smell is fantastic."

"I love the ingredients that are in BSN’s Syntha-6 protein however, this flavor doesn’t really do it for me."

"This product is extremely terrible on the stomach. It gave me diarrhea virtually every time I took it no matter what time of the day it was."

The Bottom Line – Does Syntha 6 Work?

Should you mix up a shaker of BSN protein right now? Let’s see, the addition of protein when you’re working out is important, especially in lean form. However, we have some reservations about Syntha 6 because there is not quite enough benefit for the calorie impact. Plus, there are mixed reviews about the taste and results.

If you’re ready to build more muscle, a protein shake is a good option, but so is a supplement that works to effectively boost testosterone with clinically tested ingredients.

Among the best products we’ve seen this year is one called Pronabolin. This nine-ingredient formula has been scientifically tested and shown to help boost energy, muscle growth and testosterone. Users all over the web are seeing some fantastic results and few, if any, side effects are mentioned.

Plus, the people behind Pronabolin are offering a 120-day money-back guarantee and multiple-bottle discount.

What You Should Know: A Syntha 6 Review

Syntha-6 is a whey protein product meant for body builders, though it claims to promote lean muscle development. Should BSN's Syntha-6 product be used for overall weight loss? We doubt it, but we will take a closer look. The product website does not market this product for weight loss purposes.

List of Ingredients

Whey protein.

Product Features

The Syntha-6 comes in the form of a powder that is mixed with water to create a protein drink. Besides being a good source of protein, it may have antioxidant benefits which will boost the immune system. It may even have anti-carcinogenic (cancer-fighting) properties. In terms of weight loss, it is best considered for its protein content and the fact that many people have had weight loss success using low carbohydrate, high protein diets.

The product website states that Syntha-6 "contains BCAA's (for nitrogen balance), Glutamine peptides (recovery, immune system), MCT's (fast energy) and fiber (digestive support)" It is available in eight flavors and is suitable for multiple uses throughout the day without disturbing sleep patterns.

A 2.91 pound supply, which offers 30 scoops is $45.99 plus shipping and handling on the BSN website. This is a sufficient one month supply, only if you use it once a day. Those who use it more than once a day are faced with a much more expensive venture. Trial packs that contain five different flavors are available for $9.99 plus shipping and handling for those who are interested in trying the product before making an expensive purchase.

Advantages of Syntha 6 Protein

  • Whey protein has several potential ways to improve health.

Disadvantages of Syntha 6 Protein

  • No mention of a satisfaction guarantee.
  • No user testimonials are posted for others to see.
  • No clear-cut connection to the ingredients and weight loss.


Unless you plan on using it as a meal replacement shake, this will probably not offer you too many weight loss benefits. As a meal replacement shake, Syntha-6 would be a very expensive option as compared to some other products for this purpose, and cut out some necessary nutrients. For weight loss, you need a supplement that addresses both fat burning and appetite suppression, combined with a healthy diet and exercise routine.

    So for all the people that say this doesn’t work for you. Your most likely not working out, and eating properly. Getting gains is not all about lifting in the gym. 75-80% of your gains come from sleep, and what you eat.
    expectally what your eat right after your workout. I’m talking literally mins after you work out, your muscle will start to break down. If you don’t eat mine after working out. So therefore you should be drinking a shake right after your workout!
    Also if you are not eating 4-5 meals a day I bet you won’t see any muscle at all. So you can’t just take this and expect to build. You have a eat! Sleep! Workhard. Building muscle is a science. Don’t just happen from taking a protein power. That being said I find this product does what it should:

      Hello Zeeshan. All users are different and can experience different results.

  • Your Name

    check the expiration date on the tub that he’s currently using. If that’s ok then he’s probably allergic to one of the ingredients in it. Take note that syntha 6 has ingredients like fish oil, egg, milk etc which are among the common ingredients that could cause allergies. Ur best bet is to consult a doctor.

  • Your Name

    ur basically flushing all ur efforts down the drain. I don’t think having alcohol after syntha 6 has any harms but what’s the point of all the gym training if u finish it off with a party with alcohol?

    My son is taking BSN Syntha-6 since a week. Today his whole body is under a rash. Swollen fingers as well. Can you tell me please if this product might cause allergies in some people? Thanks for your help.

    • Maribel (Editor)

      Hi Greta. Please make sure to consult with your son’s physician before he continues to take this product and let them know about the side effects he has been experiencing.

  •  Best tasting protein drink!
    Nic (Verified User)

    I have used this product extensively for a few years. Currently using the Chocolate Peanut Butter flavor, which is AMAZING. The best tasting protein drink out there, period. While this product is not marketed for weight loss, it is marketed for weight management, meaning that using this supplement with an exercise regimen and a balanced diet of SMALL frequent meals, this drink will help you shed bodyfat. The name of the game is not necessarily weight loss guys, because a lot of weight loss diets achieve results via muscle loss. Use this powder in conjunction with diets such as the Paleo Diet or the Zone Diet, and you will see INCHES disappear!

    • Tim

      When you took syntha 6 , and used it with weight loss … how much scoops did you use ? and when during the day?

      • Stephen (Editor)

        Take 1 scoop with 4-5 oz of cold water or any beverage of your choice. Vary the amount of liquid to achieve your desired flavor and consistency. Taken before meals.

  • Syntha 6 is not designed for weight loss.

    Syntha 6 is not designed for weight loss so why would you review it as such? It is for muscle growth and maintenance. If you use this without a proper weight training routine you will probably gain weight as it is pretty calorie dense. If you are trying to lose weight it is very simple: low calorie diet combined with aerobic exercise at least 6 hours a week. Voila!!
