Every compound in your stack is plotted across a 7 day window. The curve shows when concentration is highest, when it starts to fall, and where it sits relative to your next injection. Half-life just means the point at which half of the compound has cleared, and the curve shows what the whole picture looks like rather than that one number.

Receptors are the docking points compounds act on. When two compounds in a stack target the same receptor, the combined load at that receptor changes depending on how the injections are timed. The visualizer maps which receptors are shared and what the combined load looks like across the week.

For weekly compounds sharing a receptor, injecting both on the same day produces maximum combined receptor load at that moment. Separating injection days by three or four days lowers that peak. The visualizer shows how the numbers change across every day offset so you can see the difference before choosing a schedule.

Some compounds interact not through shared receptors but through effects that change the conditions the other compound depends on. GLP-1 activity that extends a fasted window is one example. The visualizer surfaces these timing notes alongside the receptor overlap so the full picture is in one place.

Enter the milligrams in your vial and the bacteriostatic water you are mixing with, and it returns the exact units to draw on a U-100 syringe, the concentration, and how many doses that vial holds. Runs across every compound in the reference set, and handles blends where several peptides come out of one vial in one draw.
