ON is one of the best although expensive whey proteins in the market. MuscleBlaze I'd never take even with a 90% discount. I've known people who reported stomach and liver problems after taking MuscleBlaze. This was several years ago but I don't expect anything changed since MB is an Indian brand.Has anyone used whey from Optimum Nutrition? Is it better than or equivalent to MuscleBlaze?
I recommend Ultimate Nutrition Prostar. It costs 5k for around 5.28lb and it's one of the most popular brands in the US too. Don't ever buy proteins on amazon or flipkart, you can try pigi or Nutristar or any other trusted importer.
