First, if weight is not moving and you are calling it a stall, have you checked a body-composition scale to see whether water is the issue? How many weeks has the stall lasted? Look at the most recent weight-loss numbers alongside body-composition data; that may clear some things up. Switching to retatrutide could be reasonable, starting at 1.5 or 2 mg since you are close to goal. If you still have tirzepatide on hand you can always try bumping it by 0.5 mg to test whether that helps.
RS has been on 7.5 mg tirzepatide with 15 pounds left to goal after an 80-pound total loss. A stall has set in. Will going higher actually move the scale or just suppress appetite more? Hunger is not really a problem at this dose while running keto in a calorie deficit. Also thinking about switching to retatrutide and curious what others say.
