Listen to what Vtool said, it’s absolutely correct. I don’t know what the deal is between Sam Biser and Dr. Schulze either, but it doesn’t really matter. Just get your hands on the Save Your Life collection. Make sure it’s the latest version and study it day and night. If you contract a deadly disease, it will save your life, and if not, it can save you a lot of time being sick from other, less lethal illnesses.
It doesn’t matter what the price is, it’s the best value you’re going to find on saving your life.
