What are healing peptides like BPC-157?

Short chains of amino acids that copy a hormone. Insulin is one. Ozempic is one. Healing peptides like BPC-157, TB-500, ipamorelin and CJC-1295, the "Wolverine stack", are sold as the sequel: if a peptide can switch off hunger, another can heal your tendon, grow your muscle, slow your aging. Ozempic proved the needle. The craze sells the needle without the proof.
