Whole blood and red cells can be stored for up to 21 – 42 days depending on the anticoagulant-preservative used. On the other hand, platelets only last from 3-5 days and fresh frozen plasma can be kept for 12 months.

Some people feel significant change as the session takes places. Others report significant change occurs hours or even days later. For some people, weeks go by until realizations of change are noticed. The changes that occur are personal and everyone's experiences are unique.
