Nice flavor, big bottle
I've used this product before and I enjoy it very much. I didn't realize I was ordering the gigantic bottle. However, on its side, it still fits on the shelf. I like the cookies and cream flavor. I use 8 ounces of milk, 1 cup of berries, and the scoop of R1 for my protein shake after my workout.

Suitable ISO100 Replacement
I swore off ISO100 due to insane cost increases. This is a worthy replacement.It doesn’t dissolve as easily as ISO, but it’s close. You’ll never know the hydrolyzed to whey ratio in this stuff - companies don’t publish it - but the dissolution suggests it’s pretty good.The taste is delicious, and I have noticed no muscle loss switching from ISO.

Six months in and loving it
UPDATE 9/8:I've now been using this daily for almost six months. I continue to be incredibly happy with the results. This, combined with increasing my calorie intake and getting in the gym every day, has helped me fill out and pack on some "healthy weight." I am 6'2" and ran track and cross country most of my life, adding muscle or weight to my frame has always been a challenge. I will continue using this product unless its formula changes or the price dramatically increases.I've been taking this daily for about a month now and am really happy with my purchase. I mix one heaping scoop with ~8 ounces of oat milk each morning after my workout and have noticed a more productive recovery time and feel better in general since adding this into my routine. This mixes great (with oat milk, haven't tried anything else) and is easy on the stomach. Texture is great. It is a tad on the sweet side, but I've only tried vanilla so far (will probably stick with this regardless).

Great for the value
Doing my research I wanted to find protein that was not expensive, but good quality and great portion. This will last me a while. Easy way to get my protein in after my workouts, The taste isn’t bad. I purchased the vanilla flavor. And there’s no gritty taste to it

Great protein option
Mixes well with water, no clumps. Slight stomach discomfort with stinky flatulent.

Highly recommend, ESPECIALLY for lactose intolerant
Wow, protein has come a long way in 20 years! I saw this protein recommended on YT, who actually sold the hell out of it (and im glad he did!), he pretty much said gram for gram that it’s hard to beat—especially for the money. Ive been lifting/supplementing for the past 20 years, havent been supplementing protein for the last 7 or so. I was not looking forward to powders again, but all the pre packaged ones either made me pooh, fart, or feel awful (lactose intolerant), so I needed to suck it up or change my goals. Got it in the mail today and I couldnt wait to try it out. I am blown away by the quality of this protein. It mixes amazingly, no clumps whatsoever. Texture is smooth. Taste is about as good as you can expect with protein. Ive had better tasting, but those were loaded with fats, sugars, and carbs. Nowhere near this clean. Keep in mind this was with water and not mixed in a blinder lol. Those who have been in it for a while know how god awful shakes used to be. Anyways, i couldnt be more satisfied. Well done.

Best protein that I have ever taken
I tried several different brands, and Rule 1 whey isolate is the best I have tried in my 11 years of lifting. The flavor is REALLY good, and the texture is milky smooth. It also mixes really well with yogurt, which makes it really easy to meet my daily protein goal. This is slightly more expensive than Pro Action Recor, which I feel is the best value, so I only buy Rule 1 when I am going through cutting cycles because it is somewhat of a premium item.If I can point to one downside, it is that we should NOT mix this with piping hot coffee because that causes it to curdle. I used to mix my whey with coffee so that I get my daily kick with some protein to start, but because the protein is so fine, it curdles much more easy in hot coffee (and that means you waste good coffee and good protein).

Best protein on the market. cheaper than the crappy grocery store kind when u buy here in bulk
I wish i had found out about this stuff sooner. I was drinking crappy grocery store brands. Those cheap kinds are poorly manufactured with harsh chemicals and causes the protein to denature. they also have a ton of filler and extra calories. sometimes they put cheap creatine and stuff you dont want in it too.. Ive noticed quite a difference in muscle gains as well as a lot of ppl have stated. Dont waste your money on other kinds. THIS IS THE ONE! rule 1. Its actually cheaper when you buy it here in bulk. My friend was going to buy some protein and i was happy to inform him that Rule 1 is the best. I would never drink any other protein. Taste is great too. Im so happy with rule 1 that i had to go on here and write a review. as a consumer advocate i highly recommend it.
