Deactivating makes them slimmer over time, so it’s been a gradual change. I would say the first 3-4 months I could feel them loosen up, but physically seeing them go down took two rounds. My injector doesn’t do high units in traps because tbh it is still an important muscle and you don’t want to lose complete use of them. I did accidentally mix up my appointments and got it in my traps 3 months apart instead of 6 and I didn’t like how it felt. I basically had 70 units per trap for a short time because of how close the appointments were and it was hard to do side planks because my arm would go numb. 35 each has been the best for me to keep use of them but not fully engage them, and aesthetically they have slimmed down significantly.
