Species Nutrition Isolyze Whey Protein Powder, 100% Whey Isolate for Muscle Building, 27.5g Protein Per Scoop, No Sugar & Low Fat (Vanilla Peanut Butter, 44 Servings)

I have been in the business now for nearly 35 years and have tried most every brand at least once. Species protein as well as the rest of the products are simply the best!! Gram for gram the highest amount of protein per serving, the quality is amazing. This coming from someone who is lactose intolerant. The taste is fantastic and it mixes superbly!! Whether you’re an athlete or just someone looking to improve your overall health. Species protein, fiber, omega’s and multi v are a winner!! If you are suffering from any aches or pains in your joints be sure to try Arthrolyze.

Great product. I've experimented with quite a few of the top, popular brands and have concluded this to be amongst the best. This is from the perspective of a guy who has and continues to workout for years.

Very, very, clean protein. I've tried alot of different brands and Species is top quality. You pay a little more, but it's a higher quality. 27.5 gms of protein per serving is higher than all other's I've tried. This mixes easily, as the miconizing makes the powder extremely fine, almost like "talc". No grittiness whatsoever. Taste is very good, but not exceptional. I have no issue's drinking it. I use MTS Nutrition Whey protein too, and as far as taste, it is the best tasting protein powder I've used. However, it's not as clean and does contain a small amount of "high fructose corn syrup", something that in my opinion, should NEVER be in a healthy supplement. Species Whey does NOT contain any high fructose corn syrup or any other negative ingredients. It does contain "sucralose", as does almost every other protein supplement, for sweetener. This is an excellent whey protein. I'll definitely buy again.

BY FAR the BEST protein supplement I have ever used and tried. I will FOREVER only use Species Nutrition for the rest of my life. It is BY FAR the best tasting, highest per Gram potency, and easiest digesting protein on the market. Best flavors and QUALITY in the entire protein shake world! It is well worth it and if it cost a few dollars more, its WELL WORTH it bc the product is the highest protein mg to Gram of powder, little to no lactose(so easily digestible), and is the HIGHEST QUALITY protein supplement made.

Very high quality protein . And the peanut butter chocolate is very nice tasting.

i use to take Speices peanut butter protein religously up until 2 years ago.. It was the best no complaints flavor was great and mixed great . I stopped working out because of COVID so stopped taking protein. I am back in the gym and went to my go to protein and this is not the same product it has NO chocolate Peanutbutter flavor at all ZERO FLAVOR .. except for Chemical taste . I read some simalr reviews that mentioned this.. and was doubtful.. but damn this stuff is just nasty!!! Some has really changed. I will never buy this again nor do i suggest you waste your money

Isolyze is a great protein product. I like it for several reasons. First, it contains 27g of protein per serving. Second, has no fat and low sodium. IT also dissolves very easily. Tastes good and doesn't cause all that gastric discomfort that other proteins do. The only reason I gave lsolyze a 4 and not a 5 star is because of the price increase and smaller size packaging..

I have used this brand from a few years now. I recently moved to a town and had no luck at any of the health store here, they didn’t carry it! I thought why not try Amazon! Thank you Amazon for coming thru and carrying a few Species products! This protein powder blends nicely, does not have a gritty taste, no after taste and does not make you gassy. I like to mix it with water and a few ice cubes. I sometimes have a had time getting enough protein in me so this is one way that helps a lot for me. I usually drink 2 shakes a day, one in the morning and then one in the evening. If you are looking for a clean protein powder this is one of my favorite brands and suggest giving it a try.
