BSN hails from Illinois, USA, and is part of the Glanbia Group, along with Optimum Nutrition. BSN has the authoritative certification of the international sports nutrition organization ISSN, and has won a high degree of recognition among professional athletes and public fitness groups, and its online sales in the European and American markets are among the top three, and it is in a leading position in the industry.
 
Both BSN and Optimum Nutrition value taste and texture, so it's inevitable that there are more additives in the formula. In contrast, ON protein powder generally has a higher protein content than BSN, and has lower calories and a purer protein composition. Most of BSN's protein powder products contain a variety of proteins with different absorption rates, so as to meet the needs of rapid absorption and slow release at the same time.
 
Syntha-6 6 Matrix Protein Powder is the core product with the highest recognition by BSN, and it is also the most nutrient-balanced protein powder, so the protein itself does not stand out. Syntha-6's protein composition is mainly concentrated whey protein and isolate casein, which has a certain amino acid release effect, which can be used for long training sessions. The product has a high content of carbohydrates and fat, while protein contains only 47%, and the additional dietary fiber and fat loss and fast energy ingredients MCT are a highlight of the formula, but this is a lot of discoloration in the face of high calories, this product can maintain and increase weight to a certain extent, but it is not suitable for people who aim to lose fat.
 
In addition, Syntha-6 contains more than 20% of the daily requirement for cholesterol per serving, which is high in protein powders. 5 pounds of Syntha-6 can be bought for about 350 yuan, which seems cheap, but if calculated according to the protein content, Syntha-6 does not have a price advantage, and there is no need to buy this protein powder if you do not need to gain weight and muscle. Similar to ON Gold Standard Protein Powder, BSN Syntha-6 is popular with gym enthusiasts due to its rich flavor profile, and in addition to the long-selling regular flavor, the COLD STONE CREAMERY series, which has a unique ice cream flavor and milkshake taste, is also highly praised.
 
If you need a protein powder with a higher protein content and lower calories, try Matrix Protein Syntha-6 EDGE and Protein Isolate Isolate, which are better than Syntha-6 Isolate from a price/performance perspective.
 
Syntha-6 EDGE is a lean version of Syntha-6, the two taste the same, Syntha-6 EDGE has a protein content of about 63%, and hydrolyzed whey protein is added to the protein composition, which can meet the needs of rapid absorption and slow release of protein at the same time. The protein content of Syntha-6 EDGE is only slightly lower than that of Isolate, and the price is much lower, about 420 yuan and 4 pounds, which is the best price-performance ratio among similar products. If low calories and zero lactose are not required, Syntha-6 EDGE is a more suitable choice.
 
Syntha-6 Isolate's protein formula consists of whey protein isolate and milk protein isolate, which is virtually lactose-free, and has the lowest fat content and calories of any BSN protein powder. However, only 4 pounds of Syntha-6 Isolate can be purchased for about 480 yuan, which is on the high side, and if you need whey protein isolate, you can refer to brands such as Myprotein, ALLMAX and Isopure.
 
When it comes to weight-changing products, BSN has two products, Isoburn Fat Reduction Protein Powder and True-Mass Weight Gainer Powder, both of which are worth recommending, especially True-Mass.
 
The protein in True-Mass Muscle Gainer is mainly composed of whey protein concentrate, whey protein isolate and casein, with a content of about 28%, with high protein content and calories, which has a good weight gain and muscle building effect, and is suitable for weight gainers to carry out high-intensity muscle building training. The 5.82 lb True-Mass is about 400 yuan, and the cost performance is higher in similar products. However, each serving of True-Mass contains 130mg of cholesterol, which is more than 60% of the daily intake, and people with high blood lipids should be cautious.
 
Unlike other fat reduction products, Isoburn is not a meal replacement, and its main property is still a protein supplement. Isoburn is the purest protein product of BSN, and has the highest protein content of about 67%, which is composed only of whey protein isolate, which is easy to digest and absorb, and can be consumed by lactose intolerant people. Therefore, the price of Isoburn is higher, only 1.32 pounds can be purchased at about 230 yuan, and there are few products similar to Isoburn on the market, so people can try it for fat loss.
