Plasma exchange and NAD+ therapy are two of the most discussed longevity interventions today. This guide compares their mechanisms, evidence base, ideal candidates, and how each may fit into a physician-guided regenerative protocol.

Prolotherapy and stem cell therapy both try to reduce chronic back pain without surgery, but they work in very different ways.

Stem cell therapy targets deeper tissue damage, including disc degeneration, and works through a different biological process entirely.

American and Canadian MS patients are increasingly exploring stem cell therapy in Mexico after limited results with conventional disease-modifying therapies. This guide covers which MS types may respond best, what safety and quality standards to look for, realistic expectations, and what makes a physician-guided protocol different from a single injection.
