I have been ordering Rule 1 products for awhile and I’m never dissatisfied, definitely the best mass gainer for more than reasonable pricing. *

Solid taste, I combined mine with strawberries and bananas for extra flavor. Mix with water, milk always makes them to thick for my liking *

Rule1 is consistently one of the best. Mixes easily and the flavors are best in the game. The macros on the weight gainers are good but not great. A good cheap stand by until I can afford the better of the mass gainers. But still very good*
