protect peptides in the bloodstream and enable slow release Polymeric micelles Enhance solubility and extend circulation time Hydrogels and implantable depots Allow for sustained local delivery (e.g., post-surgical peptide release) Transdermal patches & microneedles Non-invasive methods for delivering peptides through the skin Real-World Applications Oral GLP-1 analogs using nanoparticle carriers BPC-157 studies exploring sustained-release hydrogel formulations PEG-MGF designed with PEG chains to mimic depot-style delivery Intranasal delivery of oxytocin and growth hormone-releasing peptides Advanced peptide delivery platforms will reduce dosing frequency, improve patient compliance, and open the door to non-injectable therapeutics. Zhang et al., International Journal of Pharmaceutics Oral Peptide Therapies Available Today (and Whats Coming) For decades, the idea of oral peptides seemed impossible but recent advancements in drug delivery systems and peptide engineering have made it a clinical reality for select compounds

Connective tissues gradually lose flexibility
Patients using medications such as neuroleptics, antidepressants, mood stabilizers, and others within specified time frames before screening were also disqualified [1]
Forty-three percent stated that they discontinued the medications because they could not afford them, and 17% said that they did not have insurance coverage for them
