4.3 Gastrointestinal effects The gastrointestinal (GI) tract is greatly impacted by GLP-1RAs
How injectable/oral GLP-1 medications work: Mimic the GLP-1 hormone with engineered modifications for extended duration Bind to GLP-1 receptors to enhance insulin release and reduce glucagon Slow gastric emptying by 20-50%, promoting satiety Supported by large randomized controlled trialsthe STEP trials showed 14.9% mean weight loss at 68 weeks versus 2.4% for placebo The short answer on why patches cant deliver these drugs: GLP-1 molecules are relatively large peptide chains (molecular weight 3-5 kDa) that cannot effectively penetrate the skin barrier through passive transdermal diffusion
Preclinical Study Summary MT-I has been studied in melanocyte biology, photoprotection research, and erythropoietic protoporphyria models

For Wolverine Stack equivalent (5mg BPC-157 + 5mg TB-500): 5mg BPC-157 from a 10mg vial at C$65.69 = ~$32.85 worth 5mg TB-500 from a 10mg vial at C$79.69 = ~$39.85 worth Equivalent cost ~$72.70 vs Wolverine Stack at $79.99 (small blend premium) For Glow Blend equivalent (50mg GHK-Cu + 10mg BPC-157 + 10mg TB-500): 50mg GHK-Cu vial at C$54.99 = $54.99 10mg BPC-157 vial at C$65.69 = $65.69 10mg TB-500 vial at C$79.69 = $79.69 Equivalent cost ~$200.37 vs Glow Blend at $159.99 (~20% blend savings) So Glow Blend's per-mg looks better than Wolverine's per-mg only because GHK-Cu is much cheaper per mg than BPC-157 or TB-500
