I'm on a glp-1 too, just began a cycle. Dosing 30 mins before bed left me antsy, so I'm moving to first thing in the AM, though I train fasted, so the hurdle is staying alert enough to inject ahead of leaving for the gym. Opinions vary on whether GLPs matter for GH peptide timing at night. Most of what I've read says food sitting in the gut isn't what cancels GH peps but the insulin spike after a meal. I'm just relaying what strangers online say, so take it for what it's worth, but there seems to be some reason to think GLPs shouldn't cause major trouble for pinning at night. Best way to know is a baseline of IGF-1 with z-score prior to the cycle, then retest after 6-8 weeks, though one vial may show little, it's not a fast acting pep.
