What Customers Are Saying

The product mixes well, though some note it can be thick and requires a blender for best results. Many appreciate its high calorie content and find it easy to digest. Common feedback includes that the serving size is very large, using oversized scoops that can be challenging to consume. Some mention it can be quite sweet or cause mild nausea for sensitive stomachs. Several long-term users praise its consistency and effectiveness compared to other gainers. A few note concerns about the packaging and higher cost per serving.
