Product Overview

RSP WHEY is scientifically formulated to support muscle growth and recovery. It consists of four premium protein sources arranged to optimize muscle protein synthesis (MPS) jumpstarting and sustaining lean muscle growth and recovery.* RSP Whey is the nutritional cornerstone for your active lifestyle, making it easy to achieve your muscle-building goals and meet your daily protein intake requirements.*

The cold ultrafiltration manufacturing process maximizes purity, solubility and bioavailabilty without denaturing or comprising the quality of the protein in RSP Whey. This process ensures it is easy to mix and digest while it feeds your muscles with premium quality protein. RSP Whey tastes amazing while still being low in carbs and fat. You can use it anytime - in everything from pre- and post-workout shakes or mixing it in meal replacements.

25g of protein with 5.4 grams of naturally occurring BCAAs and digestive enzymes

25g of pure, lean muscle-building protein derived from four sources. These proteins digest at different speeds with the help of digestive enzymes and branched chain amino acids that optimize and sustain Muscle Protein Synthesis (MPS). This process is the key to maximizing lean muscle and strength gains, while decreasing the time needed for recovery.*

Most of the supplements I use are from RSP which I trust and I'm very happy with but I was a little bit disappointed from the taste (chocolate), the sweetness (too sweet) and its solubility. Great quality though, like every other RSP product.

RSP WHEY was an excellent protein as well as a great taste and mix-ability!

  • 10 Cookies & Cream

Honestly a great product, loved it so much I ended up letting some co workers try it and now that’s all you see everyone drinking. Definitely getting another jug ASAP

  • 10 Cookies & Cream

I've tried other cookies and cream protein shakes before, and this one was by far the best! Blend it with ice and almond milk and its the perfect combo!

  • 10 Cookies & Cream

I loved this protein powder! Honestly one of the best tasting shakes I’ve ever had. I’ve recommend the cookies and cream👍🏼


Loved this protein, took it post shoulder workout and it did not disappoint. Great flavor, light & satisfying.

  • 10 Chocolate

It dissolves quickly in water, the chocolate flavor is quite good, solid and very exact to chocolate. I just love the taste of chocolate in this whey.

  • 9 Chocolate

Hands down my go-to protein. High quality and tastes great for a reasonable price. Mixes well and if need of a preference, I would go with chocolate. I probably won't be buying any other protein any time soon. I highly recommend this product.

  • 9 Vanilla

I was able to sample this product and it really helped with recovery especially after leg day. The flavor Is my favorite. And mixes really well with my mixer bottle. I recommend it. And will reorder soon.

  • 8 Cookies & Cream

I really liked this protein. It did not cause any stomach discomfort. It mixed up pretty good leaving barely any chunks! Flavor resembled more cookie dough than cookies and cream, still great tasting though!

  • 8 Chocolate

I enjoyed this product.... its one of the lower calorie/carb proteins I have been able to find and enjoy. There was also no bloating afterwards which is great for those in bodybuilding where physique is always being judged and bloat can be a huge factor

  • 9 Chocolate

Really enjoyed this protein. Great flavor and mixed very well. Didn't have the stereotypical "protein" taste. I would definitely buy again.

  • 7 Chocolate

RSP sent me a package of products to try and one was there whey. So for the last week ive been useing it daily after my 430am workouts. And it has shown to help speed recovery especially after leg day. Which is what I dread the most. Ive been using the chocolate peanut butter which is A little chalky but I do mix A little almond milk with it for more flavor. Overall I will reorder soon.

  • 10 Cookies & Cream

I tried out the rsp whey in cookies and cream, and the taste was really good, it was like a creamy cookies and cream, mixed great with water, and had little bits of chocolate cookies in the powder that also tasted good. Reminded me of a DQ oreo blizzard. I would definitely recommend the cookies and cream flavor.
