## Verdict

A cheap grocery-aisle bar with only 10g of protein and a candy profile, outclassed on every value metric by Kirkland and Pure Protein. Buy the Kirkland Signature Protein Bar instead.

## For

- More affordable than many protein bars
- Tastes like candy, per an RD-reviewed guide
- A shelf staple shoppers reach for on brand trust
- Affordable snack for kids and adults
- Each bar tastes like candy

## Against

- Only 10g of protein per bar
- A snack bar wearing a protein costume
- Listed among the most glyphosate-contaminated tested products
- Modest protein count for the category
- Underdelivers as a protein purchase compared with rivals at similar cost

## Flagged as one to avoid

This product entered 4 of 5 runs as one buyers cross-shop but should not buy, rather than as a pick. It is published here rather than dropped.

## Evidence

Backed by one cited source so far

Limited coverage: fewer than two distinct outlets are cited for this placement. Read it as a weaker reading than a product with broad coverage.

## What this tier means

- F: Avoid. The evidence points you elsewhere.

## How to read this

- Each category is researched in four independent runs, one per lens (expert consensus, value, reliability, community pulse). Every run ranks a board of candidates that deliberately includes products buyers cross-shop but should avoid. Placements score on a ranked ladder (LP), and tiers are derived from LP, so no tier is ever assigned by hand.
- LP is this product's points on its own category ladder. It is comparable within a category and not across categories.
- Link status reports what our pre-publication link check found when it fetched the cited URL. It says nothing about the quality of the review.
- A citation with no usable link is listed rather than dropped, and is excluded from the counted total above.
