How close should the results be to the label?
At Bulk Nutrients, our products are almost always within 2% of the protein level we claim — but not every company holds themselves to the same standard. While guarantees vary, you may have grounds for a refund if a product is 5–10% below its stated protein content.
If you’re planning to test a protein that wasn’t purchased from us, it’s worth asking the company in advance what their guarantee is. That way, you’ll know exactly where you stand before the results come in.
