Easier to hit protein goals for those gainz! Tasted pretty good. I always mixed with water, raspberries, PB and honey maybe. Review: Great tasting protein shake - I decided to purchase this protein drink after a couple of my co-workers recommended it. They had both gone through weight loss surgery and were given this protein drink to use to before and after surgery. This protein drink is less powdery tasting than most other protein drinks that I have tried. The peanut butter flavoring in this drink does not taste anything like a peanut butter shake but it is better than any of the store bought peanut butter protein shakes. I actually purchased this one with the chocolate protein shake to make a peanut butter and chocolate protein shake. I would not recommend that! They both taste great separately but together the flavores do not mix well. I would recommend freezing the shake first. The taste is much better when it is really cold and the thickness created from mixing them makes it seem more like a frozen treat. If you are wondering if this shake will make you feel full.. It will! If you are disciplined enough to follow a plan this shake really does help with results. ## Features - Multi-Source Protein Complex: Features Undenatured Micellar Casein and Egg White Protein for comprehensive muscle recovery and growth - Sustained-Release Protein Blend: Advanced formula delivers a continuous stream of amino acids throughout the day for optimal muscle support - Premium Quality Ingredients: Contains rBST-Free, Grass-Fed Whey for superior protein nutrition and quality assurance - Low Carb Nutrition: Zero sugar and low carbohydrate content supports lean muscle development and fitness goals - Complete Protein Matrix: Combines ultrafiltered whey protein, micellar casein, native egg white protein, and glutamine peptides for comprehensive amino acid profile ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00DOS9XEE | | Age Range Description | Adult | | Allergen Information | Milk, Soy | | Best Sellers Rank | #35,373 in Health & Household ( See Top 100 in Health & Household ) #191 in Sports Nutrition Whey Protein Powders #4,679 in Sales & Deals | | Brand | Syntrax | | Brand Name | Syntrax | | Customer Reviews | 4.6 out of 5 stars 584 Reviews | | Diet Type | Halal, Kosher | | Flavor | Peanut Butter | | Global Trade Identification Number | 00893912125301 | | Item Dimensions | 7 x 5 x 13 inches | | Item Nype Name | Protein Powder | | Item Weight | 2 pounds | | Manufacturer | Si03, Inc | | Manufacturer Part Number | M2BPB | | Material Type Free | rBST-Free | | Model Name | Matrix | | Model Number | M2BPB | | Net Content Volume | 2, 32 fluid ounces | | Number of Items | 1 | | Package Type Name | Pouch | | Product Benefits | Extra Protein Support, Supports Muscle Endurance, Supports Muscle Growth, Supports Muscle Health | | Protein | 23 g | | Protein Source | Blend | | Recommended Uses For Product | Pre-Workout | | Servings per Container | 25 | | Supplement Formulation | Multi-Supplement | | Total Servings Per Container | 25 | | UPC | 810007540092 893912125301 772195086939 810007540863 | | Unit Count | 32 Ounce | ## Product Details - **Brand:** Syntrax - **Flavor:** Peanut Butter - **Item Weight:** 2 pounds - **Material Type Free:** rBST-Free - **Servings per Container:** 25 ## Images ![Matrix Sustained‑Release Protein Blend, Peanut Butter Cookie, 2 lb - Image 1](https://m.media-amazon.com/images/I/71GBFoSNaIL.jpg) ## Available Options This product comes in different **Size, Flavor** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Gainz o clock *by A***G on December 25, 2025* I would use this in my nightly shake.

This one is no different. It mixes very well and is easy to drink. To me, tastes close enough to a peanut butter cookie to give it 5 stars.
