Potency testing in general but ESPECIALLY for weight loss products is crucial to ensure patients achieve desired results. If the potency is lower than required, patients may not lose as much weight as expected, potentially leading to dissatisfaction and mistrust in their healthcare provider and pharmacy. Patients might seek alternative providers with reliable potency-tested products, impacting provider-patient relationships and continuity of care. Thus, conducting potency tests helps maintain patient satisfaction, trust, and retention, benefiting both patients and providers in the long run.
