More than a year ago when the only peptide I was taking was Semaglutide, I was suffering from very frequent migraines. Someone told me Glutithione helped decrease hers. I started taking about 1000mg orally and not only did it decrease my migraines but it gave me energy and improved my mood. Shortly after this, I discovered grey peptides. I learned I could pin it sub q for even better results. I get great results pinning 200 to 300 mg every day with vitamin c. The vitamin c can be injectable or oral. When injectable Glutithione is unavailable I take about 1500 mg oral for simular results. Unfortunately it looks like I need to stop it for a bit. Lately the migraines are coming back a little so hopefully it will regain its power after the pause.
