Injection site rotation.

Site rotation is the part of an injectable protocol that is easiest to get wrong, because the failure mode is invisible for weeks. PepCue handles it the only way software honestly can: by remembering where you have already been and showing you the pattern.

How it works.

When you log a dose you tap a site on a body map. The map shades recently used areas, so the next available site is obvious at a glance rather than something you have to recall. If you let the app advance the site for you, it moves through the areas you enabled in order and skips the ones you have marked unavailable.

Reading the rotation score.

The insights view scores how evenly your sites are distributed over a rolling window. A low score means clustering, which usually shows up as the same two convenient spots taking most of the doses. The score describes your own logged pattern and nothing more. It is not a clinical assessment, it does not know your anatomy, and it cannot see the tissue it is scoring.

What the app deliberately does not do.

• •It does not tell you where to inject, or which sites are appropriate for a given compound
• •It does not set a minimum interval before returning to a site
• •It does not interpret lumps, soreness, bruising, or any other tissue change
• •It does not decide whether a site should be retired

Those are clinical judgements that depend on the preparation, the volume, the needle, and your own body, and they belong with the person who prescribed or supervised the protocol. What the app contributes is an accurate history, which makes that conversation concrete: instead of saying you have been rotating, you can show exactly which sites took which doses over the last two months.

Notes belong here too.

If a site is sore, bruised, or slow to settle, attach a note to that entry with a severity. Site-specific notes accumulate into the single most useful thing in the log, because they let you and a clinician see whether an issue follows a site, a compound, or a batch.
