Hi Debby, great questions here! Dr. Jockers curates his own support packs using evidence based products he has used for years and may also be lower cost. Dr. Jockers strives to provide Support Packs for all budgets. Whether you follow CellCore's product packs and guidelines, the same health goals are intended. Whether an individual needs to continue a phase longer varies depending on how great your detox need, dosing during the protocol or even how often you have completed other detox protocols recently. We offer health coaching and suggest working 1:1 with someone who can guide you through this process and determine what is best for your needs.
