Pros
- +24g plant protein per serving with a complete amino acid profile (pea + rice blend)

- +Vegan Society certified; no artificial colours or flavours
- +Added Vitamin B12 and C to support energy metabolism
- +Multiple reviewers report visible lean muscle gains and performance improvements over 6–8 weeks of consistent use
Cons

- -Grainy, thick texture noted by multiple reviewers; can feel heavy or 'floury' mixed with water alone
- -Allergen label lists Milk despite plant-based marketing — contradicts vegan positioning and may be a cross-contamination risk
- -One reviewer reported severe throat soreness lasting several days after consumption
Best For
Watch Out
- !Milk allergen listed on packaging — verify with manufacturer if strictly vegan or dairy-allergic

- !Throat irritation reported by at least one user — discontinue if similar symptoms occur
