Best price and selection. Fast shipping too

Promasil - Cookies & Cream + Strawberry & Cream

Both of these flavors are great. I can hardly believe it's a protein shake when I take it. Also I find it mixes easily compared to others I've tried.

I prefer to mix it with soy milk and an ice cube, I find that to be far superior to taking then with only water.

Promasil - Rich Chocolate

This has been my favourite protein for several years. It is clean, easy on the digestive system and the most delicious protein powder that I have ever found. I highly recommend trying it and supplement source always has the best price!
