Feature Deep-Dive
3D injection site tracking. Not a flat image. Not a list.
Most injection site logs are a tap on a flat body outline. Protocol builds a spatial record across eight zones on a 3D model, color-codes tissue rest in real time, and suggests the next site automatically.
No other peptide tracker app has this.
Green — rested
Safe to inject

Why rotation matters
Injecting the same site repeatedly causes lipohypertrophy — the buildup of scar tissue from repeated trauma and fat deposit stimulation. The tissue feels rubbery. Absorption from lipohypertrophic tissue is inconsistent and slower than healthy subcutaneous fat. On a protocol requiring precise dosing, inconsistent absorption produces inconsistent results.
The clinical recommendation for subcutaneous injections is rotation across a minimum of four to eight distinct sites, allowing each site at least 48 to 72 hours of rest before reuse. On a daily injection protocol with multiple compounds, tracking this manually is unreliable.
Protocol tracks it automatically. Log a dose, tap the location on the 3D model, and the map updates. The tissue rest color coding means you never have to remember when you last used a site — the model shows you.
Eight tracked zones
Protocol tracks injection history across eight body zones shown simultaneously on the 3D model with front and back views: upper abdomen, lower abdomen, left thigh, right thigh, left glute, right glute, and both deltoids.

FAQ
How does Protocol's injection site tracker work?+
Protocol uses a 3D anatomical body map with simultaneous front and back views. When you log a dose, you tap the exact injection location on the 3D model. Sites are color-coded by tissue rest status: green for fully rested, orange for recently used, red for used today. The app suggests the next injection site based on your logged history across eight body zones.
What is the difference between Protocol's 3D map and a 2D injection log?+
A 2D injection site log records which zone you injected in as a list or flat image tap. Protocol's 3D model tracks the spatial location of each injection across eight zones with tissue rest status shown visually. You can see at a glance which areas are rested, which are recent, and which were used today — across your entire body simultaneously, front and back.
Why does injection site rotation matter?+
Injecting the same location repeatedly causes lipohypertrophy — the formation of fatty lumps from repeated trauma and fat deposit stimulation. Lipohypertrophy creates inconsistent compound absorption because scar tissue absorbs less reliably than healthy subcutaneous tissue. Regular rotation across eight zones prevents this. Protocol's color-coded map makes rotation systematic instead of guesswork.
How many injection zones does Protocol track?+
Protocol tracks injection history across eight body zones: upper and lower abdomen, left and right thigh, left and right glute, and deltoids. Each zone is shown on the 3D model with tissue rest status. The app suggests the next site automatically based on which zones are most rested.
Which peptide tracker apps have a 3D injection site map?+
Protocol is the only peptide tracker app with a fully rendered 3D injection site body map. PepTracker, DoseTrack, and some other apps have 2D flat image injection logs. Shotlee has basic injection site tracking. No other app provides a 3D spatial model with color-coded tissue rest status and automatic site suggestions.
