- +Some users report real mass gains when used as an extra meal during a bulk
- +Mixes reasonably well in a shaker compared to many gainers
Cons
- -Heavy maltodextrin content — one reviewer reported a blood sugar spike and crash from half a serving
- -Significant wind and gas reported, even by users who otherwise like the product
- -Flavour reportedly turns stale and bitter towards the bottom of the bag
- -Grainy undissolved powder in some flavours, and one buyer flagged a mismatch between the Amazon ingredients list and the actual product label
Best For
