Choosing protein nutrition usually comes down to three practical questions: do you want whey or plant protein, which flavor will you actually use consistently, and how much are you comfortable paying for the tub in front of you? The four options here sit in a narrow listed price range, but they split clearly by protein source, flavor, and included attributes.
Quick take
- Lowest listed price: Optimum Nutrition, Gold Standard 100% Whey Protein Powder, Double Rich Chocolate at USD 29.99. It is the straightforward pick if chocolate whey is the flavor and format you want.
- Plant-based pick: Optimum Nutrition Gold Standard Plant Protein Powder Vegan 0g Sugar 15.7 oz. It is the only vegan option in this group and uses pea protein, fava bean protein isolate, and brown rice protein concentrate.
- Thin Mints whey pick: Optimum Nutrition Gold Standard 100% Whey Protein Powder Thin Mints 24.8 oz and the similarly named Thin Mints option both focus on a flavored whey powder with gluten-free listed among the features.
- Price spread: The listed prices run from USD 29.99 to USD 37.99, so the lowest option is about 21% below the highest.

Decision matrix
Choose the Double Rich Chocolate whey powder if price leads the decision. It has the lowest listed price in the group and stays in the familiar 100% whey powder lane. The flavor is also more classic than Thin Mints or Creamy Vanilla plant protein, which may matter if you want something easy to pair with common shake additions.
Choose the Thin Mints whey powder if flavor variety is the main reason you are shopping. Both Thin Mints entries point to a whey-based powder, with ingredients centered on whey protein isolate, whey protein concentrate, and hydrolyzed whey protein. That makes them closer to each other than to the plant-based option.
Choose the plant protein powder if vegan and 0g sugar are must-have attributes. It is the only product here with vegan and 0g sugar called out directly, and its listed ingredients move away from whey entirely.
Narrow between the two Thin Mints entries by attributes. One Thin Mints listing calls out no artificial growth hormones along with gluten-free, while the other spells out the whey protein isolate, whey protein concentrate, and hydrolyzed whey protein active ingredients more directly.
Concise product notes
Optimum Nutrition, Gold Standard 100% Whey Protein Powder, Double Rich Chocolate
This is the easiest pick for shoppers who want the lowest listed price and a conventional chocolate whey powder. The title names Double Rich Chocolate, and the attributes include powder formulation, gluten-free, high protein, and alcohol free. It also has a United States country of origin and an expiration date of 08/26 listed. The main limitation is that it does not carry the vegan or 0g sugar callouts found on the plant protein powder, and the title does not include a container weight. If you want a familiar whey flavor and the lowest price in this comparison, this one has the clearest role.
Optimum Nutrition Gold Standard 100% Whey Protein Powder Thin Mints 24.8 oz
This Thin Mints whey powder is a strong fit if flavor is a big part of sticking with a protein routine. The description centers on whey protein isolate as the primary ingredient and also mentions whey protein concentrate and hydrolyzed whey protein in the ingredient list. The attributes include powder formulation, gluten-free, no artificial growth hormones, a 32 g dosage, and Thin Mints flavor. Its limitation is price position: it sits above the Double Rich Chocolate whey powder while using the same broad 100% whey product family. It also is not the vegan choice, so shoppers avoiding whey should look to the plant protein option instead.
Optimum Nutrition Gold Standard Plant Protein Powder Vegan 0g Sugar 15.7 oz
The plant protein powder is the cleanest match for shoppers specifically seeking vegan protein nutrition. Its title highlights Vegan, 0g Sugar, and a 15.7 oz container, while the attributes list Creamy Vanilla flavor and powder formulation. The ingredient mix includes pea protein, fava bean protein isolate, brown rice protein concentrate, coconut oil creamer, and sunflower oil, so it is meaningfully different from the whey entries. The tradeoff is that it has the highest listed price in this group and the smallest visible container weight among the products with size stated in the title. Pick it for the plant-based formulation, not for lowest upfront cost.
Optimum Nutrition Gold Standard 100% Whey Protein Powder, Thin Mints, 24.8 oz
This second Thin Mints listing is best viewed as the more ingredient-explicit Thin Mints whey option. Its active ingredients are listed as whey protein isolate, whey protein concentrate, and hydrolyzed whey protein, and the ingredients also include cocoa processed with alkali and sucralose. The title and attributes align around Thin Mints flavor, powder formulation, gluten-free, and muscle support and recovery as the stated main purpose. The limitation is overlap: it shares the same flavor and container size language as the other Thin Mints whey product, while matching its listed price. The reason to choose this one is the clearer whey blend wording in the attributes.
How to choose by shopper type
If you are restocking a basic whey powder and care most about the number on the tag, the Double Rich Chocolate option is the most direct match. It costs less than the others and avoids the decision complexity of choosing between two nearly identical Thin Mints entries.
If taste novelty matters, Thin Mints is the standout flavor in the whey subset. Between the two Thin Mints products, shoppers who like a broader feature callout may prefer the version that includes no artificial growth hormones, while shoppers comparing ingredient language may gravitate to the version that names all three whey forms as active ingredients.
If you want to avoid whey, the decision is simple: the Creamy Vanilla plant protein powder is the only option here that is vegan and built around pea, fava bean, and brown rice protein ingredients. Its price is the top of the range, but it is also the only one that solves the plant-based requirement.
Final recommendation
For most price-sensitive whey shoppers, start with Optimum Nutrition, Gold Standard 100% Whey Protein Powder, Double Rich Chocolate because it is listed at USD 29.99, the lowest price in the comparison. For a whey powder with a more distinctive flavor, choose either Optimum Nutrition Gold Standard 100% Whey Protein Powder Thin Mints 24.8 oz or Optimum Nutrition Gold Standard 100% Whey Protein Powder, Thin Mints, 24.8 oz; the deciding point is whether you prefer the no artificial growth hormones feature callout or the more detailed whey active-ingredient wording. For shoppers who require vegan protein nutrition and want 0g sugar called out, the clear pick is Optimum Nutrition Gold Standard Plant Protein Powder Vegan 0g Sugar 15.7 oz, even though it is the highest listed price at USD 37.99.
