Testing & Certifications Explained

Hampshire Labs does not have any third-party testing certifications on record. This means that no independent organization has verified the quality, purity, or potency of their products. While not inherently unsafe, the absence of third-party testing makes it more difficult for consumers to be confident in the accuracy of product labels and the absence of contaminants. Consumers seeking third-party tested supplements should look for certifications like NSF Certified for Sport or USP Verified.

How Hampshire Labs Compares

Compared to competitors like Klean Athlete (Trust Score 85/100, NSF Certified for Sport) and NOW Foods (Trust Score 78/100, Informed-Sport), Hampshire Labs' Trust Score is considerably lower. These competitors invest in third-party testing and certifications to demonstrate product quality and safety. Another competitor, Nutrafol (Trust Score 62/100), also has a higher trust score, but also lacks comprehensive third-party testing.
