About XTEND

XTEND is a protein supplement brand operating as an independent company based in the US. The founding date of XTEND is unknown. They offer a range of products aimed at athletes and fitness enthusiasts.

XTEND primarily focuses on protein supplements. They are known for their branched-chain amino acid (BCAA) products, protein powders, and recovery formulas designed to support muscle growth and repair.

Testing & Certifications Explained

XTEND does not appear to have any third-party testing certifications. This means that no independent organization verifies the quality, purity, or potency of their products. Consumers should be aware that the absence of third-party testing means that product claims are not independently validated. Therefore, consumers cannot verify if XTEND is third-party tested.

For example, Klean Athlete (trust score 85) and NOW Foods (trust score 78) both have higher trust scores and certifications from organizations like NSF International and Informed-Sport. These certifications provide an additional layer of assurance compared to XTEND.
