PEScience Smart Mass Gainer is a Gourmet Vanilla mass gainer for convenient bulking, with 14 pre-portioned packets offering 225 calories, 25g of protein, and 25g of carbohydrates per packet.
Adding calories and protein to a bulking routine can be difficult when there is little time to measure ingredients or prepare a full meal. Smart Mass is made for convenient servings at home or on the go, and the brand also positions it as a meal replacement option when you are in a rush. Its packet format gives each serving a defined portion, while its protein and carbohydrate blend is designed for use after a workout, between meals, or before bed.
Each packet provides 225 calories, 25g of protein, and 25g of carbohydrates. The protein combines whey, which absorbs quickly, with slower-digesting casein; together, these complete protein sources support sustained amino acid release. The mix is intended to fit several points in a day, including after training, between meals, or before bed.
The carbohydrate blend uses pea starch (Carb10), Palatinose (isomaltulose), and oat bran rather than maltodextrin. These slow-burning carbohydrate sources are intended to support steady energy release for lean bulking; the brand describes the formula as designed to support energy without a crash. This sets its carbohydrate approach apart from typical gainers that rely on simple sugars or maltodextrin.
Yes. Its 14 individual packets are made for people who want a pre-portioned serving without carrying a tub or scoop. When time is short, the brand also presents Smart Mass as an on-the-go meal replacement option. The packet format keeps portioning simple, whether the serving is used after a workout or between meals.
Smart Mass is best suited to people looking for a convenient mass gainer with set portions, whey-and-casein protein, and carbohydrates from sources other than maltodextrin. Its packet format and stated meal-replacement use also suit busy routines; it is designed for bulking support rather than as a tub-based powder that requires scooping.
