bpc-157 upregulates growth hormone receptors Pentadecapeptide BPC 157 Enhances the Receptor Expression in Tendon Fibroblasts BPC 157 and TB 500:

Unlike the peptides in this list, 5-Amino-1MQ is a small molecule (not a chain of amino acids) but its often discussed in the peptide therapy world for its outsized impact on metabolism

Genetic basis for increased intestinal permeability in families with Crohn's disease: role of CARD15 3020insC mutation

, relapse (10, 11), poor healing of the fistulas (35), unhealed intestinal anastomosis (42, 43), massive intestinal resection leading to short bowel (43), and functional incapability of the post-anastomotic remained intestine (43), and, along with these, particularly for multiple sclerosis, direct demonstration of the healing of the severely injured muscles and severely injured nerves and brain injuries (15-23, 59) so far not mentioned with DMDs (61), these results obtained in two models, cysteamine enema and then colon-colon anastomosis and cuprizone may define a particular way not relied on immunomodulation
