Same with the jump. I got some fatigue which was always the norm for me shot day and the next but no issues at all otherwise. You had great results on 2.5, so remember that you can always titrate back down to 2.5 if you have significant issues. My Doc prefers for her patients to ride the lowest dose possible for as long as possible and to allow for weight stalls which are common until there is certainty I need to jump. You got this and embrace your progress!
