Transparent Labs Whey Protein Isolate

Our verdict

Transparent Labs Whey Protein Isolate works out to $2.17 per serving of whey protein, at 28g per serving in powder form. That puts it around the median of the 33 whey protein products we can price per dose, where the typical serving costs $2.00. One container lasts 30 days at the label dose of 1 serving a day, about $64.99 a month. We could not verify a third-party certification for Transparent Labs in a public registry.
