For me it's 1.5 mg twice a week, Sunday morning at 8 and Wednesday evening at 8. Eight weeks in and it hits pretty hard, no side effects, no hungry days. Every 5 days was something I tried earlier, but the shot day drifts each week, and that makes planning a pain. I want to feel good on Friday and Saturday so I can enjoy my food a bit more. Get the GLP Plotter, it keeps you from overdosing. Math is easy: 5mg weekly is about 0,714 mg a day, so a 5 day gap would be 3,57 mg per shot. A bit more than that is probably what you'll want, since the peaks and valleys flatten out this way and most people still want the peak.
