Injection site rotation planner
Rotating injection sites gives each spot time to recover between shots. Tick the sites your prescriber showed you, in the order you want to use them, choose how often you inject, and see which site comes next for your next 8 injections.
This is an educational estimate, not medical advice. It doesn’t recommend a dose. Real levels vary a lot between people; only a blood test shows yours. Talk to your prescriber before changing anything. Use only the sites your prescriber or nurse showed you.

How it works
The planner works the way TRTracker does: your rotation is an ordered list of sites, and each injection takes the next site in that list. With the sites in the order you ticked them, every site gets the same rest between injections: the number of other sites times the days between injections.
If you choose no sites, TRTracker starts from a default: the quads, then the glutes for intramuscular injections; the lower abdomen, then the outer thighs for subcutaneous ones. In the app, if a site was used recently it suggests a better-rested one instead and tells you why.
Sides are your own. On the front view your right side is on the left of the picture, as if you were facing a mirror image of yourself; on the back view your right side is on the right.
This plan is a reminder, not a medical instruction. Your prescriber or nurse decides which sites and which route are right for you.

Questions
Why rotate injection sites?
Using the same spot again and again can leave it sore, lumpy or scarred (lipohypertrophy), and absorption from damaged tissue can be less even. Spreading injections over several sites gives each one time to recover.
How many sites should I rotate between?
Use the sites your prescriber or nurse showed you. With four sites and weekly injections, each site rests about three weeks; with twice-weekly injections, about 10 days. More sites give each one more rest.
Which sites are for subcutaneous injections?
The abdomen and the back of the upper arm are subcutaneous sites; they are marked SubQ. The outer thigh is used for both. Deltoids, glutes, quads and the ventrogluteal site are usually intramuscular. Your prescriber decides which route and sites you use.
Which side is left and right?
Sides are your own: “right glute” is on your right. On the front view your right side is on the left of the picture; on the back view it is on the right.
