The full guide
What it is and how it works
Each serving provides 50 g of protein and 1,340 calories, supporting high-calorie needs for mass gain and recovery. The formula includes whey protein (dairy), creatine, and BCAAs; it is labeled gluten-free and is described as 3rd-party tested in product data, which many users look for when evaluating gluten safety and quality. Container size is large, and some listings note that the container provides 9 servings, though availability and packaging details can vary across retailers.
Gluten safety and certifications
The product is labeled gluten-free, but the data provided does not show explicit gluten-free certifications (such as GFCO or NSF) evidence. Certifications listed in the data are not present. Cross-contact information from the facility is not disclosed in the data, so explicit cross-contact assurances are not evidenced. The gluten-safety verdict given in the data is 'likely_safe' with medium confidence, based on gluten-free labeling and dairy-based formulation, rather than documented facility certifications.
Taste, texture, and tolerance
Taste feedback is mixed: some reviewers find the vanilla ice cream flavor appealing, while others consider it very sweet. Digestive tolerance varies, with some buyers reporting stomach discomfort after use. Mixability is noted positively by many reviewers, particularly with milk, contributing to a perception of good quality and value for some users.
Who it's for and how to use
Best for individuals seeking to increase mass/weight with a high-calorie, high-protein supplement, and for athletes looking for a combined protein, creatine, and BCAA formula for post-workout recovery and growth. Not ideal for those avoiding dairy or seeking plant-based options, or for anyone sensitive to sweetness or digestive issues. People needing explicit gluten-free facility certifications or cross-contact assurances may want to verify current certifications and manufacturing details with the retailer. Use considerations include pairing with milk or other liquids, noting the high calorie and protein content, and understanding that price per serving may vary by retailer.
Value, price, and comparison
The product is described as premium-priced at $51.99 for a large container, with some listings noting 9 servings. Price per serving and overall value may vary by retailer. Key differentiators include 50 g protein per serving, 1,340 calories per serving, and the inclusion of creatine and BCAAs, plus third-party testing. It also stands out for gluten-free labeling, though explicit gluten-free facility certifications are not evidenced in the listed data. Compared with other gluten-free mass gainers, this product emphasizes high protein and calories along with combined ingredients (creatine and BCAAs) and gluten-free labeling, but users should consider potential taste preferences, digestive tolerance, and current stock availability.
