Love Promasil
Best-tasting protein out there mixed with both water and smoothies.
December 4, 2017
I'm very unhappy with this product. I paid good money and for some odd reason this stuff is very hard to mix. It does not taste bad

Look no where else for a quality protein. 25 grams of protein in a 31 gram serving size. Been using for 3 years. They various blends in this create a long lasting protein for absorption.
This protein mixes extremely easily in water and the vanilla is very tasty. Really tastes like vanilla ice cream. Never disappoints. Great buy on sale works out to about .50 per serving

Keeps you full, no BS inside.
I got a 2 pound in store on clearance and it is fantastic! There is no BS in it, low sugar and carb counts plus a crazy amount of protein for one scoop.

This stuff keeps me feeling fuller than any other I have used and it blends super easy. I only got chocolate because that is what I had tried from the start, if I saw single packs I would be more inclined to try other flavors.

Terrible taste and mix
Great protein for overnight recovery but It's not easy to mix, even with a blender. I tried both water and skim milk but it lacks consistency. It tastes terrible.

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).

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.
