Allmax Isoflex vs PVL ISOGOLD vs Rule 1: Whey Isolate Buying Guide
Compare Allmax Isoflex, PVL ISOGOLD and Rule 1 whey isolate by tub size and flavour. Find the right shopping option at SuppVerse Canada.
Compare the exact tub, not just the brand
These three ranges are listed as whey isolate products in our catalogue. Package sizes differ, so a lower tub price does not automatically mean a lower cost for the same amount of powder. Start with the size you want and the flavour you will actually use.
| Range | Listed sizes | Flavour examples |
|---|---|---|
| Allmax Isoflex | 2 lb and 5 lb | Chocolate, Vanilla, Chocolate Peanut Butter, Cookies & Cream |
| PVL ISOGOLD 840 g | 840 g | Strawberry Milkshake, Triple Milk Chocolate, Ice Cream Cookie Sandwich, Iced Mocha Cappuccino |
| PVL ISOGOLD 4 lb | 4 lb | Vanilla Milkshake, Rocky Road Ice Cream and other listed options |
| Rule 1 R1 Whey Isolate | 5 lb | Chocolate Fudge, Vanilla Crème |
Choose a smaller tub or a larger format
If you have not tried a flavour, compare the smaller Isoflex and ISOGOLD packages first. If you already know the flavour, compare the larger tubs by net package weight and current price. ISOGOLD’s 4 lb tub and the two 5 lb options contain different amounts of powder; compare them using one unit of weight.
Divide the selected variant’s price by its net weight to calculate cost per gram. To compare cost per serving, use the serving count printed on each current label. Do not treat one brand’s scoop as equivalent to another brand’s serving.
Match the flavour and label information
Flavour selection differs between sizes. A flavour listed for one tub is not necessarily offered in another size. Check the selected product page for stock, then read the physical package for ingredients, allergens, nutrition and mixing directions. This comparison covers shopping formats; it does not rank the formulas by performance or prescribe a serving size.
Where the other options fit
The whey isolate collection also includes MUTANT HARDCORE ISO. For a different Rule 1 format, see our Rule 1 whey blend versus isolate comparison. If you are shopping for a plant powder, explore plant protein.
