Study finds CBG more stable than CBD in a six-month topical formulation test

University of Campinas researchers found CBD-rich and CBG-rich extracts showed laboratory antioxidant and antimicrobial activity, while CBD content fell about 65% and CBG content fell 16% in accelerated six-month topical-emulsion testing. Oklahoma product developers should view the result as an R&D stability signal, not a basis for medical claims, because the formulations were not tested in patients.
