Real nutrition (per ~30.4g scoop, Double Rich Chocolate)
Macros are nearly identical across flavours; a few (such as Chocolate Peanut Butter) run slightly higher at about 130 calories on a ~33g scoop. Always check the label on your tub.
| Nutrient | Per scoop |
|---|---|
| Calories | 120 |
| Protein | 24 g |
| Total fat | 1.5 g (1 g saturated) |
| Total carbohydrate | 3 g |
| Sugars | 1 g |

Ingredients (Double Rich Chocolate): protein blend (whey protein isolate, whey protein concentrate, hydrolyzed whey protein), cocoa (processed with alkali), sunflower and/or soy lecithin, natural and artificial flavour, acesulfame potassium. Contains milk and soy. It is gluten-free and Informed Choice certified (batch-tested against banned substances).
Is the 5 lb tub worth it? The cost-per-serving math
This is the whole reason to size up. You are buying the exact same formula — the only thing that changes is the price per shake.
| Size | Price | Servings | Protein/serving | Cost/serving | Cost per gram of protein |
|---|---|---|---|---|---|
| 5 lb tub | $149.99 | ~73 | 24 g | ~$2.05 | ~$0.086 |
| 1.5 lb tub | $64.99 | ~22 | 24 g | ~$2.95 | ~$0.123 |
The 5 lb works out to roughly $0.90 less per shake — about 30% cheaper per serving. For a once-a-day user the big tub lasts around two to three months and pays for itself quickly. If you are new to the brand or want to taste a flavour first, the 1.5 lb is the low-commitment pick; once it is your daily protein, switch to the 5 lb.
What sets Gold Standard apart (and the trade-offs)
- Consistency. The macros are exactly what the label claims, and the taste and mixability are the same tub after tub — a big part of why it has stayed the category benchmark for decades.
- Mixes clean. It is instantized, so it dissolves with just a glass and spoon — no blender needed.
- Isolate-led blend. Whey isolate is the number-one ingredient, which keeps carbs and fat low (3g and 1.5g) while protein stays high at 24g.
- Trade-off — it is a blend, not a pure isolate. If you need the leanest possible macros or are sensitive to lactose, a dedicated isolate like whey isolate may suit you better.
- Trade-off — contains milk and soy. Not suitable for dairy-free or soy-free diets.
Flavours in stock
The 5 lb tub currently comes in a wide lineup:
- Double Rich Chocolate — the all-time best-seller; a safe, true-cocoa first pick.
- Extreme Milk Chocolate — sweeter and milkier.
- Vanilla Ice Cream — the most versatile; great in smoothies, oats and baking.
- Cookies n' Cream — a cookies-and-cream dessert shake.
- Chocolate Peanut Butter — chocolate with a peanut-butter note (slightly higher calories).
- Mocha Cappuccino — coffee-forward; good iced.
- Strawberry and Strawberry Banana — lighter fruit options that mix well with milk.
