ON Gold Standard 100% Whey
The industry benchmark for over two decades. Optimum Nutrition (ON) Gold Standard is a blend of whey protein isolate, concentrate, and peptides. We sent the Double Rich Chocolate flavour to the lab.
Lab Results vs Label Claim
| Metric | Label Claim | Independent Lab Result |
|---|---|---|
| Protein (per 30.4g serving) | 24g | 23.6g (Pass) |
| Carbohydrates | 3g | 3.2g |
| Fat | 1.5g | 1.6g |
The product passes our label accuracy test, coming well within the acceptable 5% manufacturing variance.
Amino Acid Profile
The amino acid profile shows no signs of spiking. The leucine content is approximately 2.5g per serving, which is sufficient to trigger muscle protein synthesis for an average-sized adult.
Sensory and Mixability
This is where ON excels. It mixes flawlessly in water with a standard shaker cup—no blender balls required. The Double Rich Chocolate is not overly sweet, avoiding the cloying artificial taste common in cheaper brands.
Value Density
At approximately £0.85 per 25g of protein, it is priced at a premium compared to pure concentrates like Myprotein. You are paying for the brand reliability, the superior mixability, and the inclusion of whey isolate.
Final Verdict
It remains the gold standard for a reason. It is reliable, accurate, and tastes good. If budget is not your primary concern, it is an excellent choice.
