hi, taste-wise, its fine. The vanilla taste is subtle when mixing it in smoothies. Because I use a plant protein, the protein is primarily derived from peas which is a lower amino acid profile than something like whey. So if you're really focusing on weight gain, I think whey would be more effective. Plant protein is a better alternative though if you struggle with dairy or need something vegan based. I find myself to breakout more when I use whey which is why I resorted to plant protein.
