Research Account Review
GammaPeps supplies research-use-only reference compounds and reviews account and order information to evaluate RUO eligibility. Information such as organization details, stated research purpose, and order history may be reviewed before an order is accepted. A National Provider Identifier, professional license, or checkbox acknowledgement does not by itself establish research eligibility, and we do not represent that any customer has been credentialed or verified as a researcher. Orders that do not meet our eligibility criteria may be canceled and refunded.
