Pricey but worth it
This protein powder was recommended by the nurse practitioner I see for weight loss. I’ve been on a GLP-1 since January and have lost a significant amount of weight. It’s extremely important to get adequate protein, because these meds can cause muscle loss. The protein is $$, but doesn’t have all the crap that other powders have. I mix it with fresh berries and nonfat Greek yogurt. Plus it’s plant based which I prefer. I highly recommend this product.

Serious Whey Isolate for Serious People about their nutrition
First of all, if you’re a person that know how to distinguish BS from products, you’re supposed to be deciding between buying the following 4 products here on Amazon:1) Raw Organic Whey Concentrate – 100% Grass-fed USDA Organic Whey Protein Concentrate2) Opportuniteas Grass Fed Whey Protein Powder Isolate3) Grass Fed Whey Protein Isolate – by Muscle Feast [The one I’m reviewing]4) Antler Farms – 100% Grass Fed New Zealand Whey Protein IsolateMost of all other “whey proteins” are junk!!! Why I need to have in the ingredients things like: added sugars (including stevia, erithritol, all alcohol sugars, etc. ), xanthan gum, artificial or “natural” flavors, sodium chloride (YES!!! a few brands…LOL), tapioca starch, maldodextrin [thickener or filler to increase the volume of a processed food. Usually justified as a preservative but the large amounts used ij some products make obvious their use as a filler!], etc.I personally use the first 3 brands [Raw Organic Whey Protein Concentrate, Opportuniteas Grass Fed Whey Protein Isolate and Muscle Feast Whey Protein Isolate]. For my pre-workout I drink a smoothie with real organic strawberries, organic skim milk, organic non-fat greek yogurt, 1 banana and 1 serving size of Raw Organic Whey Concentrate. Then for my post-workout I drink 1 serving size of Opportuniteas Grass Fed Whey Protein Isolate or Muscle Feast Whey Protein Isolate with water and a serving size of organic oven roast turkey. With that combination and of course with my overall whole foods nutrition I’m doing extremely well during my job hours and during training at the gym!!!I use both, concentrate (I like the extra sugar of milk lactose) and isolate, just to go down to some details of the digestion process but if you need only one protein, just go with isolate. With that said, the only minor inconvenience I found with this product (and also Opportuniteas too) is that it is not organic like the whey concentrate from Raw Organic Whey Concentrate. But the problem is that I cannot find 100% grass-fed USDA Organic Whey Protein Isolate (just whey protein concentrate from RAW Organic Whey). For now, Opportuniteas Grass Fed Whey Protein Powder Isolate and this product are the best whey protein isolate out there.Antler Farms Whey Protein isolate is extremely similar to this product and Opportuniteas, except that it has too much sodium per serving size. For example, Opportuniteas have 40 mg of sodium per serving (30 grams of serving and 27 grams of protein -90% protein) and Antler Farms have 157 mg of sodium (Really!!!!???) per serving (30 grams of serving and 27 grams of protein -90% protein). That is 117 mg of sodium more per serving!!! There is no way I’ll buy that. Also, I don’t really understand why in this world it has so much sodium compared to the other 3 I use if they only have Whey Protein Isolate and <1% of sunflower lecithin?In overall, stay away of most other brands of "Whey Protein Powders" including Jym Stoppani, Athlean-X, Legion, OPTIMUM NUTRITION GOLD STANDARD, Junk for Life, blahblahblah, etc... LOL They have junk inside!!! [This is my PERSONAL OPINION OF COURSE!!!]Just buy this product, Grass Fed Whey Protein Isolate - by Muscle Feast, Opportuniteas Grass Fed Whey Protein Powder Isolate or Raw Organic Whey (100% Grass-fed USDA Organic Whey Protein Concentrate). Those 3 products are the only ones I use and recommend! Good luck!!! :-)P.S. - I have a similar review on Opportuniteas Grass Fed Whey Protein Powder Isolate product here on AMAZON. As you can appreciate, I recommend 3 differerent products from 3 different companies that are not related! That's because is my personal opinion!

It’s ok
I’ve only been using the unflavored powder for about a week so far in my coffee with a hand held frother. I wanted to give it a shot since I’m a 40 year old female who doesn’t think she was getting enough protein in her diet.I think the serving size for a scoop is too much so I have only been using half along with my collagen peptides. I originally thought the protein powder would easily dissolve in hot coffee like the collagen does but it does not. After trying several days, I found that it is best if I first mix it with a little hot water which makes a foam from the frother then pour it on my hot coffee. It’s not hard but one extra step and another dirty mug that I didn’t have to do before in the morning.On another hand, after doing some research before purchasing, I have found that this brand of isolate is one of the cleaner brands in regards to not adding extra ingredients and making sure it’s below FDA limits in metals from the soil. It doesn’t upset my stomach or give me diarrhea like protein concentrate has. I like that I can buy it on Amazon and it’s more affordable that some other comparable brands.

Do not recommend over other products
Regret purchasing. I did a good bit of research on this before purchasing but this stuff is way too ” foamy ” I can add it to about 8 oz of water and by the time I blend it, it will almost fill the entire pitcher full. I can’t even begin to finish it because I would have to drink 3 or more full glasses to do so. After putting what’s leftover in the fridge it will lose a bit of the foamyness but after mixing it after everything has settled it fills right back up again. If it does that in the blender image what it’s doing in your stomach. Really really hate I spent that much on a product I wont touch again.

Good protein powder that meets our criteria
We have been trying protein powders for years – maybe 50 different brands over the past decades. It is hard to find one that meets our criteria: Low temperature processed, cross microfiltrated, no synthetic/dangerous sweeteners, good mixability, not too high in sodium, not a whey concentrate, no strong stevia bitterness, good vanilla flavor, not excessively expensive.This Muscle Feast Isolate is pretty close to meeting all of our criteria. It does have a slight stevia flavor, but it is not excessive. It mixes easily. Sodium levels are quite low. The vanilla flavor is actually very pure and high quality.The price is not really great but is better than Jay Robb which we used to purchase. In fact, this protein powder is very similar to Jay Robb in flavor and characteristics.Muscle Feast Isolate is a bit on the sweet side, but we always mix our vanilla proteins with Biochem Natural which makes it only moderately sweet.It is amazing to hear how many folks complain about the packaging. Who leaves it in the original package, anyway? It is nice they stopped using plastic tubs – environmental waste plus *microplastics* which get into the food. BAD! So we are using a nice large glass container with airtight rubber seals. Don’t care a whit about the original package.All in all, this is a good protein powder and we are happy to have found it.
