Choosing a protein nutrition powder often comes down to a few practical questions: which flavor you will actually use, how much powder is in the container, whether the formula details match your routine, and how much the listed price changes between similar-looking tubs. The four choices here cluster into two groups: three Optimum Nutrition Gold Standard 100% Whey powders at the same listed price, and one BSN SYNTHA-6 whey protein powder at the top of the range.
Quick take
- Best for a cookie-inspired flavor: Optimum Nutrition Gold Standard 100% Whey Thin Mints Gluten-Free Powder 24.8 oz, because it is the only Thin Mints flavor in the group and lists gluten-free among its features.
- Best straightforward chocolate pick: Optimum Nutrition Gold Standard 100% Whey Powder Double Rich Chocolate 24.05 oz, because it pairs the Double Rich Chocolate flavor with powder formulation and a 30.4 g dosage.
- Best if serving count in the title matters: Optimum Nutrition Gold Standard 100% Whey Double Rich Chocolate 1.5lb 22 Serv, because the title clearly calls out 22 servings.
- Best for Chocolate Milkshake flavor: BSN SYNTHA-6 Whey Protein Powder, Chocolate Milkshake, 28 Servings, because it is the only BSN option and the only product here with 28 servings in the title.
Across the group, the listed price range runs from $36.97 to $84.99, with the lowest listed price 57% below the highest. That spread makes the decision less about whether all four are identical and more about whether the flavor, serving count, and formula wording justify moving away from the lower-priced cluster.

Concise product notes
Optimum Nutrition Gold Standard 100% Whey Thin Mints Gluten-Free Powder 24.8 oz
This is the most distinctive flavor choice among the Optimum Nutrition Gold Standard entries. The Thin Mints flavor makes sense for shoppers who do not want another standard chocolate tub, and the formula lists whey protein isolate, whey protein concentrate, and hydrolyzed whey protein. It also lists gluten-free and no artificial growth hormones among its features. The limitation is that the flavor is very specific: if you want a classic chocolate profile, the Double Rich Chocolate options are closer fits. It also does not put a serving count in the title, unlike the 22 Serv and 28 Serv products.
Optimum Nutrition Gold Standard 100% Whey Powder Double Rich Chocolate 24.05 oz
This Double Rich Chocolate powder is the cleanest pick if you want the familiar Optimum Nutrition Gold Standard name in the title with a chocolate flavor and a clear 24.05 oz size. The attributes include protein and BCAAs as active ingredients, plus a 30.4 g dosage, powder formulation, gluten-free, and no artificial growth hormones. The main drawback is overlap: another Optimum Nutrition Double Rich Chocolate entry is listed at the same price and calls out 1.5 lb and 22 servings in the title. If serving count is a deciding detail, that nearby alternative is easier to compare at a glance.
Optimum Nutrition Gold Standard 100% Whey Double Rich Chocolate 1.5lb 22 Serv
This version is useful for shoppers who want Double Rich Chocolate but also want the serving count visible before digging deeper. The title states 1.5 lb and 22 Serv, while the attributes list powder formulation, 30.4 g dosage, and ingredients including whey protein isolate, whey protein concentrate, hydrolyzed whey protein, cocoa powder, and sunflower and/or soy lecithin. Its limitation is that it looks very close to the 24.05 oz Double Rich Chocolate option, including the same listed price. If you care more about the ounce wording than the serving-count wording, the 24.05 oz product may be the simpler read.
BSN SYNTHA-6 Whey Protein Powder, Chocolate Milkshake, 28 Servings
The BSN SYNTHA-6 choice is the outlier in both flavor and price. It uses Chocolate Milkshake rather than Double Rich Chocolate or Thin Mints, and the title clearly states 28 servings. The attributes also list powder formulation, whey protein type, United States country of origin, and 2.91 pounds item weight. That makes it a reasonable match for shoppers prioritizing the BSN name, Chocolate Milkshake flavor, and the larger serving count shown in the title. The tradeoff is cost: at USD 84.99, it is the highest listed price here and sits well above the three Gold Standard choices.
Final recommendation
For most shoppers comparing these four protein nutrition powders by listed price first, the strongest starting point is one of the Optimum Nutrition Gold Standard 100% Whey options at USD 36.97. Choose Thin Mints Gluten-Free Powder 24.8 oz if flavor variety is the main reason you are buying; it is the only Thin Mints option and lists gluten-free among its features. Choose Double Rich Chocolate 1.5lb 22 Serv if you want the serving count spelled out in the title. Choose Double Rich Chocolate 24.05 oz if the ounce size and chocolate flavor wording are enough for your comparison.
Pick BSN SYNTHA-6 Whey Protein Powder, Chocolate Milkshake, 28 Servings when the Chocolate Milkshake flavor, BSN name, 28-serving title, and 2.91-pound item weight matter more to you than staying near the lower end of the price range. The price spread is substantial, so the BSN option makes the most sense when those specific title and attribute details are what you want.
