The body naturally produces numerous peptides, including insulin, ghrelin, GLP-1, GIP, BPC 157, oxytocin, and thymosin beta 4.

“Your body makes hundreds of peptides. Insulin is a peptide. Grein is a peptide that's involved in satiety. We're going to talk about that in this video. GLP-1 of osmpic and mangaro fame is a peptide as is gip as are things like BPC 157 which actually occurs naturally in the secretions from your stomach. Oxytocin is a peptide that's the love hormone that's released when you're hugging someone you care about or when you have sex and have an orgasm. Thyosin beta 4, which is actually the parent molecule of a peptide we'll talk about in this video called TB500.”
