There is no evidence to suggest that BPC-157 causes weight gain. BPC-157 is a peptide that is naturally occurring in the human body and has been studied for its potential therapeutic effects on the body, particularly in the healing of injuries and digestive tract disorders. While it has been shown to have several potential benefits, weight gain is not one of them.
However, it is important to note that weight gain can occur as a result of other factors such as a poor diet, lack of physical activity, hormonal imbalances, or certain medications. If you experience unexplained weight gain while taking BPC-157, it is important to speak with your healthcare provider to rule out any other potential causes.
