How to keep a peptide log you can actually trust

A tracking log is only as useful as it is consistent. If half your entries live in a notes app, a few are on a sticky note, and the rest are in your head, the data cannot tell you anything. Here is how to keep a record you can actually trust.

Write down the three things that matter#

Every entry should capture what you took, the date and time, and the site. With those three you can reconstruct adherence, rotation, and rough timing later. Without them, you are guessing.

Log at the moment, not from memory#

The biggest gap in most logs is the entry someone "definitely remembers" making. Record it as you do it. A home-screen widget or a one-tap entry removes the friction that makes people skip it.

Rotate sites on paper, not just in your head#

Keeping a simple record of where each entry went is what makes real rotation possible. A body map that remembers usage and shows which site has rested longest does this for you, so rotation happens by default instead of by willpower.

Keep it yours#

A log full of personal health detail does not belong in someone else's cloud. On-device storage with an easy export means the record stays useful and private — yours to keep, yours to delete.
