A deficiency in B12 can lead to fatigue, weakness, numbness, tingling sensations, and memory problems
These treatments may help people lose weight and control certain health problems more effectively than with diet and exercise alone

Most people get B12 from food such as meat, fish, eggs, or dairy

In the United States, the FDA issued guidance in 2023 indicating that BPC-157 cannot be used as an active pharmaceutical ingredient in compounded medications under Section 503A or 503B of the Federal Food, Drug and Cosmetic Act
