Developed by a leading strength coach and doctor, this GMP certified product ensures no fillers or additives, making it a clean choice for fitness enthusiasts. ## Description This product was designed by Dr. Jordan Feigenbaum to his specifications and is GMP certified so you know that you’re getting what is on the label. Whey Rx is a non-GMO whey protein isolate (WPI), which means that it has a higher amino acid and protein concentration with fewer calories from carbohydrates and fats than other types of proteins. You’ll notice that there are only four ingredients in our product: whey protein isolate, vanilla, natural flavors, and Stevia. This simple combination doesn’t include the additives that other products have, giving you more of what you want with zero junk. In fact, the only things we’ve added to the protein are the muscle-building branched-chain amino acids (BCAAs) leucine, valine, and isoleucine. These are the workhorses of any protein source — without them, it doesn’t matter how many grams of protein a supplement has, because it won’t work optimally without the right amount of BCAAs. We spared no expense making a high quality, minimally processed, BCAA-packed protein because there isn’t anything like this on the market. We hope you like it as much as we do! What’s in it?- 30 servings of Non GMO Whey Isolate, Cocoa Powder, Natural Flavors, and Stevia. - Each serving has 3 grams leucine, 1.5 grams valine, and 1.5 grams isoleucine - No fillers, no protein spiking, no gums, thickeners, or additives. - This is a high quality whey protein currently unlike anything else on the market. How do I take it? We recommend using 1 serving at a time, mixed with 6-80z of water, milk, or other liquid. 1 scoop contains enough BCAAs to drive muscle protein synthesis in just about everyone. So, while there’s no harm in taking 2 scoops at a time-there’s no benefit either and economically you’re better off using a single serving at a time.

I usually order the chocolate. I'm not a years-long consumer of whey protein powders, and can't really compare this one to any other ones on the market. But I have been listening to the Barbell Medicine guys since Rippetoe let Feigenbaum run the nutrition board on the Starting Strength forums and I trust them to give good advice concerning nutrition.The vanilla flavor has a slightly off taste (for vanilla), but the chocolate is excellent. So, three stars for the vanilla and five for the chocolate, for an average of four stars. To date, I haven't had any reason to defect to something less expensive.20190703 update:Well, I think I know how I ended up ordering vanilla. When I click through a previous order for "chocolate", this is the page I land on. The description mentions "cocoa", but the title is now "Barbell Medicine, Whey Protein Isolate Powder with BCAA, Jordan Feigenbaum, Non-GMO, GMP, Vanilla, 786 Gr..." There doesn't seem to be any way to order chocolate, either by search or a previous order. Perhaps whatever happened to cause this has happened before. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Perfect except for Stevia aftertaste. Wishing for an unsweetened version. *by K***O on Reviewed in the United States on January 27, 2020* I bought this product because of its leucine content and short ingredient list: whey protein isolate, natural flavors, and stevia. I hestitated over the stevia because I don't usually like it, but read a review that said the stevia taste was "light" so I thought I would try it, especially since other whey isolates also use either artificial sweeteners or stevia plus lots of fillers.The product is creamy when mixed with milk or yogurt and the vanilla flavor is very nice.But for me, the stevia aftertaste lingers all day. I hope that some day Whey Rx will come in an unsweetened version. People would be free to add their own sweetener or none at all. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Blend with fruit *by C***A on Reviewed in the United States on August 6, 2020* You definitely need to blend it with a banana or some fruit to make it taste good. I tried it with only coconut milk in a blender bottle and I could not drink it. Once blended with fruit, it’s great! It’s not too thick like some other vegan proteins, so I appreciate that. I’ll likely keep buying it because I like that it has a small list of ingredients. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/66444094-barbell-medicine-whey-protein-isolate-powder-with-bcaa-vanilla](https://www.desertcart.co.uk/products/66444094-barbell-medicine-whey-protein-isolate-powder-with-bcaa-vanilla) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-01*
