Detailed Review

Optimum Nutrition Gold Standard Whey Protein in Double Rich Chocolate is a trial-size tub offering 24g of protein per scoop. It is designed for athletes and fitness enthusiasts who want a reliable, third-party tested protein powder to support muscle recovery and growth. This 0.68 lb pack contains 10 servings, making it ideal for travel or as a sample before buying a larger container.

The primary source is whey protein isolate, which is rapidly absorbed by the body, making it effective post-workout. The instantized formula mixes easily with water or milk using a shaker cup, producing a smooth, clump-free shake. Users report a rich double chocolate flavor that is enjoyable as a standalone drink or blended into smoothies.

The tub is compact and sturdy, with a resealable lid to keep powder fresh. Each serving scoop is included, though the small size means you will need to replace the tub after 10 uses. The powder itself is fine and dissolves well, with no grittiness. As a product made in the USA and banned substance tested, it meets high quality standards.

The main limitation is the serving count: only 10 servings per tub, which may not be economical for regular users. Additionally, while the chocolate flavor is popular, taste preferences vary, and some may find it overly sweet. For best results, a shaker cup is recommended as spoon mixing can leave clumps.

Overall, this is a high-quality whey protein from a trusted brand. It is an excellent choice for those wanting a portable protein source or a low-commitment trial. For daily heavy use, a larger tub would be more cost-effective. But for its convenience and purity, it earns a strong recommendation.
