Good to hear. Is the main objective purely weight loss for you? Building up a reserve of reta sounds like a sensible approach either way. No clue what you're currently running weekly, but my setup is 5mg tirz to start the week and 5mg reta midweek on Thursday. Same situation here with the 20 and 30mg vial sizes, the math lines up reasonably well against my dosing. I've got a batch of the 40mg size arriving soon, and even then the numbers still seem to work out, they came at a decent price so it hardly matters. Wishing you good luck with the whole plan.
