GNC Pro Performance Bulk 1340 Benefits

Muscle Energy And Growth

GNC Pro Performance Buk 1340 contains 50 grams of high-quality protein intended to support high-intensity workouts and fuel you through your exercise regime. This product contains whey protein isolate, which is a quality source of protein that contains essential amino acids like branched-chain amino acids (BCAAs). These amino acids help support muscle growth and muscle energy effectively. Branched-chain amino acids have specifically been shown to increase muscle protein synthesis, which leads to muscle growth and “bulking.” BCAAs also help delay and prevent muscle fatigue. Another amino acid is glutamine, which helps reserve protein stores in the body to help you build more protein and muscle mass after workouts.

Supports Muscle Recovery

The whey protein isolate in this product supports muscle recovery due to the branched-chain amino acids. Essential amino acids like leucine, valine, isoleucine, and glutamine help support effective muscle recovery after workouts while also delaying muscle fatigue and soreness. Creatine is also included in the Bulk 1340 formula as it helps muscles recover more quickly during exercise. Creatine also improves muscle strength as well, which helps with overall recovery.

Supports Immune Health

10 grams of an amino acid known as glutamine is included in this formula. Glutamine is particularly beneficial for immune health. When we suffer from illness or a weakened immune system, our glutamine levels naturally lower, so supplementing with this amino acids helps treat and prevent illness, keeping our immune system strong and healthy.

GNC Pro Performance Bulk 1340 Ingredients

The main ingredient in GNC Pro Performance Bulk 1340 is whey protein isolate. Whey protein isolate is a protein source derived from cows. However, in the isolate form, it contains less lactose and more protein (90%). It also contains less fat. Whey protein contains a great amino acid panel featuring essential amino acids and branched-chain amino acids. These amino acids are essential for our health, especially when it comes to supporting muscle health. These amino acids support muscle growth and prevent the loss of lean muscle. Branched-chain amino acids specifically help promote muscle protein synthesis, leading to muscle gain. BCAAs and essential amino acids also help promote effective muscle recovery after exercise and can help delay and prevent muscle fatigue.

Another amino acid included in the whey protein isolate and in the Bulk 1340 supplement is glutamine. 10 grams of glutamine are included in Bulk 1340 and contribute to effective immune health and support. Glutamine levels naturally drop during illness and coincide with weakened immune systems. By supplementing with glutamine, our immune systems grow stronger and are more capable of handling toxins and things like free radicals.

Another essential ingredient in Bulk 1340 is an Energizing ATP Complex. This complex contains creatine, which has been proven to support muscle growth, strength, and delayed muscle fatigue. Creatine also helps delay and prevent muscle soreness, which contributes to more effective muscle recovery. Another ingredient in this ATP complex is inositol. Inositol is anabolic, so it helps enhance stamina and leads to faster muscle building. The other ingredient in this blend is para-aminobenzoic acid (PABA). It is a non-essential amino acid that is also considered a B vitamin, which helps the body create natural energy to use for enhanced performance.

Other ingredients in Bulk 1340 is cocoa powder for flavor and sucralose for a source of sweetener. Sucralose is an artificial sweetener that is very sweet and can cause bacterial issues in the gut as well as other digestive issues.

Is GNC Pro Performance Bulk 1340 Really Healthy?

GNC Pro Performance Bulk 1340 is an interesting supplement. There is a lot of protein in this product and a lot of great essential amino acids, including very beneficial branched-chain amino acids. However, this product contains a lot of carbohydrates and calories per serving. Bulking with this supplement definitely is meant for those engaging in high-intensity and high-performance activities. It’s also a bit concerning as this high-calorie supplement does not contain all of the nutrients you need. If it’s being used as a meal replacer (which at such a high-calorie amount, it probably is), it doesn’t really cover all of your daily nutrient and vitamin requirements. This supplement also contains sucralose, a very concerning artificial sweetener known to cause digestive issues and has even been linked to diabetes.

Who Should Use GNC Pro Performance Bulk 1340?

GNC Pro Performance Bulk 1340 is definitely intended for individuals engaging in high-performance and high-intensity athletic activities. It is definitely marketed towards athletes and individuals looking to bulk up and create more muscle in their body. This supplement should not be consumed if you do not engage in high-intensity activities or a fitness regimen. Always consult with your doctor before taking a supplement like this, even if it does fit in with your activity level and lifestyle.

Is GNC Pro Performance Bulk 1340 Safe?

This supplement is generally safe, but there are some issues. First off, sucralose can cause a lot of digestive issues like constipation, bloating, nausea, diarrhea, and indigestion. It has also been linked to diabetes and other preventative diseases. In terms of whey protein isolate, 50 grams of protein is a lot, so be aware of this. This much whey protein may cause muscle cramps, digestive issues, headaches, and nausea. Some users even experience drastic hair loss with large amounts of whey protein consumption.

Always consult with your doctor before taking a high-calorie, high-carb supplement like this. This product may also lead to weight gain and certain nutrient deficiencies based on what your diet and lifestyle look like.

Alternatives To GNC Pro Performance Bulk 1340

Although GNC Pro Performance Bulk 1340 is a great protein option for athletes and fitness gurus, there are better options. First off, there are some other whey protein products that, despite containing half the amount of protein as Bulk 1340, also contain a lot less carbohydrates and calories per serving. This may make room for more nutrient-dense, high-protein meals that are more important for your body than a protein powder. A great whey protein product to consider My Protein USA Whey Protein. This whey protein supplement is highly rated and comes in whey isolate form, which is more protein and less fat/dairy. It contains a complete amino acid profile and only 90 calories per serving.
