Awesome product.
The first time I tried this, it was about 50% off on top of a buy-two-get-one deal, so I got about 15 pounds of this stuff for around $60. An awesome deal for ANY protein, let alone Promasil. I don't want to sound like I am raving, but this is probably the best protein I have ever had. The protein-to-calorie ratio is unbeatable. (22g of protein with 100 calories.) The taste was not very intense, which some people may not like, but I definitely prefer it. There is little-to-no aftertaste as well. It is also very easy on the stomache. I often have problems digesting certain brands of protein, but not this one. The only downside to this protein is that there are no added BCAAs. (This does not mean that there are none in the protein, but just none are added). However, this isn't much of a problem if you supplement with BCAAs anyway. Awesome product -- I would recommend it to anybody who is looking for a new, effective protein.

Promasil protein is very good in terms of supplying a steady stream of amino acids throughout the day. No fillers, just a great, clean effective product.

Best. Protein. Ever.
Best protein I ever tasted. It's easy to mix in a shaker and I can mix it with just water. It has a great taste and consistency. Also, it's not as harsh to the stomach as other proteins (I usually get acid reflux from protein shakes). It gives a great amount of protein per scoop and I can feel the difference at the gym when I take it. I take a scoop pre workout and one scoop after. It's been a little hard to find at the GNC stores, so when I see it, I stock up. The chocolate flavor is the best (if you like chocolate).
