Dosing adjustments and special considerations Holding or reducing dose When to hold at current dose: Moderate-to-severe GI symptoms Symptoms that haven't resolved after 3-4 weeks Any concerning side effects When to reduce dose: Symptoms intolerable at current level Significant weight loss plateau doesn't require maximum dose Maintenance phase after reaching goals How to hold: Stay at current dose for an additional 2-4 weeks Then attempt escalation again If symptoms recur, may need to maintain at lower dose Missed dose protocol If you miss a dose: Take it as soon as you remember if within 4-5 days If more than 5 days, skip and resume normal schedule Never double dose to make up for missed injection If you frequently miss doses: Set weekly reminders Choose a consistent day (many choose Sunday) Consider adjusting day if schedule conflicts Population considerations For those with kidney impairment: Limited data available Slower titration may be warranted More frequent monitoring recommended Discuss with provider before starting For those with liver impairment: Retatrutide is hepatically metabolized Caution in moderate-to-severe liver disease May need dose adjustments Requires provider guidance For women: Similar dosing to men in trials May have stronger appetite suppression effects Some may need slower titration Contraception recommended during treatment For older adults: May need slower titration Increased monitoring for dehydration Start at lowest dose More frequent check-ins Comparing retatrutide dosing to other medications Retatrutide vs

For the quantification of sulfur metabolites in serum, the metabolites in 20 uL of serum were extracted and derivatized by NEM in 80 L of ice-cold extraction solvent (80% MeOH: 20% H2O containing 25 mM NEM and 10 mM ammonium formate, pH = 7.0) which includes stable isotope labeled internal standards (1 M [ 13 C 3 , 15 N]-cysteine-NEM, 0.1 M [ 13 C 2 , 15 N]-GSH-NEM, 2 M [D 4 ]-Cystine, 4.6 M [ 13 C 5 , 15 N 2 ]-GSSG, 5 M [D 4 ]-Hypotaurine, and 40 M [ 13 C 2 ]-Taurine followed by incubation at 4 C for 30 min
