Big Whey, Hydro Big or All In: which Red Rex protein is which?

Red Rex has more than one protein, and the names tell you the source.

• Big Whey: whey protein, listed at 24 g of protein per serving, in 2.25 lb and 4.5 lb tubs.
• Hydro Big: hydrolyzed whey protein, in 800 g and 1.6 kg tubs.
• All In Protein: a blend of beef, whey and plant proteins.
• All In Isolate: a blend of beef, whey and plant isolates.

So check the name before you compare two tubs. A whey tub and a blend are different products.

Big Mass, Beef Mass or Beef Mass Plus?

The mass gainers differ in size and in servings. Big Mass comes in a 12 lb tub. Beef Mass is a 6 lb tub listed at 14 servings. Beef Mass Plus is also a 6 lb tub, listed at 8 servings, so each serving is larger. Carbo Big is a different thing: a maltodextrin carbohydrate powder in a 1.5 kg tub. See gainers from other brands on the mass gainers page.

Creatine, amino acids and the rest of the range

Red Rex sells creatine in two forms, monohydrate and HCl. The amino range covers BCAA, Glutamine, EAA+ Creatine HCl, Beta-Alanine and Beef Amino tablets. Liquid L-Carnitine comes in fruit punch, pineapple and watermelon.

If you are new to the brand, start with Big Whey in the 2.25 lb tub, in a flavour you know. Compare other brands on the whey protein page, or see all creatine.

Red Rex in the Black Friday sale

During WayUP's Black Friday sale, Red Rex products with a sale price also appear on the Black Friday page. They are on the up to 30% off page too. Up to 30% off is the name of that group, not the reduction on every tub, so check the price on each product. This page is the main Red Rex page either way. Compare Big Whey, the All In blends and the mass gainers here first.
