RedBak makes up one of the four major Australian sports nutrition brands, with the other notable brands including, Musashi, Maxs and Body Science. Unlike many other protein supplement manufacturers, RedBak have their own licensed factory where they make their own products. This gives them unparalleled control over quality. Moreover, RedBack’s manufacturing plant is certified with the therapeutic goods administration as meeting the Good Manufacturing Practices (GMP) standard. All this means that RedBak produce quality products that are true to label. As a consumer, this gives true peace of mind that what you are consuming is what is on the label.

Rapid WPI Whey Protein Content and Quality

Rapid WPI’s main claim centres’ on its quality whey protein isolate content. Rapid WPI contains exclusively, whey protein isolate extracted using cross-flow microfiltration. This particular extraction technique is considered to be the best for retaining the integrity and function of whey protein isolate’s various fractions. For more information on cross-flow microfiltration and associated whey protein extraction techniques, please see our article: choosing the best protein supplement.

Unfortunately, unlike many of their Australian competitors, RedBack do not provide a breakdown of the amino acid profile of their protein on their label. This information can be very useful to determine things such as BCAA and/or leucine per serve. What we can tell you is that for every 30 gram serve of Rapid WPI, you get 25.9 grams of protein, making Rapid WPI a great quality WPI with a relatively high protein percentage.

Additional Components in Rapid WPI

Added to the base of whey protein isolate are the amino acids glutamine and taurine. On closer inspection, RedBak include these two amino acids with every protein powder they make. Glutamine and taurine are both important amino acids that can be limiting when it comes to optimising recovery from weight training. Unlike most run of the mill WPI’s, Rapid contains a spectrum of vitamins and minerals. Some people find it a comfort to know that while throwing down their protein shake, there also getting a swag of vitamins to help meet their daily requirements. The last component worthy of mention is the inclusion of a small amount of fibre in the form of inulin. While it’s questionable what effect if any a gram of fibre will have on one’s health, it’s nice to know that you’re getting a bit of extra fibre with your protein shake.

Rapid WPI Taste & Mixability

Rapid WPI has a good taste, with most forum feedback rating it as good to very good. Rapid WPI has received very little in the way of poor reviews when it comes to taste. By the same token, Rapid does note generally rank amount the top tasting WPI’s. So bottom line is you’re unlikely to be dissatisfied with the taste of Rapid WPI, but some may not find it the best they have ever tasted. Mixability wise, Rapid mixes well with no major grittiness or unmixed lumps of protein.

Rapid WPI Packaging & Sizes

As with all RedBack products, Rapid WPI comes packaged in an outer cardboard box with an inner plastic sealed bag. If you’re a sticker for protein in plastic tubs, then you might not like the cardboard packaging. However, the one advantage is that you can discard the cardboard outer and just use the flexible plastic inner, which is easier to squeeze into a bag if you need to carry it with you. In terms of sizes, Rapid WPI comes in three different packs, 1kg, 3kg and 4.5kg, with the 4.5kg coming in at just 4 cents a gram.

Rapid WPI Value For Money

At just 6 cents a gram, Rapid WPI is right up there in the value rankings for pure WPI’s. Add to this the fact that you get some vitamins, minerals and a pinch of fibre with each serve and you have a very good value for money WPI. Remembering that Rapid is produced in TGA accredited GMP facilities; when purchasing Rapid, you get a great quality protein at a great price.
