How to keep a peptide dose log
A useful peptide dose log records seven things for every dose: what you took, how much, when, where you injected, which vial it came from, how you felt and anything unusual. Log each dose at the moment you take it, in one place, and review the record before each appointment.
What to record for every dose
| Field | Example | Why it matters |
|---|---|---|
| Name | As written on the label | Avoids mix-ups between similar vials |
| Amount and unit | 250 mcg | The unit matters as much as the number |
| Date and time | 8 Oct, 7:30 am | Shows real intervals between doses |
| Injection site | Abdomen, left | Supports site rotation |
| Vial or lot | Lot 24A117 | Ties the entry to a batch |
| Notes | Taken after breakfast | Context you will not remember later |
| Side effects | Mild redness at site | Something to raise with your clinician |
Always write the unit. "250" on its own could be mcg, mg or syringe units, and those differ by factors of a hundred or a thousand.
Log at the moment, not from memory
Entries reconstructed the next day are where logs go wrong: times get rounded, sites get guessed and a skipped dose gets recorded as taken. The fix is to make logging part of the routine itself. Log before you put the vial away.
That is the practical argument for a phone app over a notebook: the phone is already in your pocket, and the time is filled in for you. In PepVault's dose log an entry is the name, the amount and a tap on the body map.
Record what you did, including the misses
A log is a record of what happened, not what was planned. If you missed a dose, took it late or changed the site, the log should say so. Those entries are the ones a clinician finds most useful.
Keep the vial record next to the dose record
Dose entries make more sense when you can see which vial they came from. For each vial note the strength, lot number, the date it was opened or reconstituted, its expiration date and how it is being stored. See how to track vial inventory and expiry.
Add a few measurements
If you and your clinician are watching an outcome, such as weight or waist, record it on a regular schedule in the same place. A weekly measurement taken at the same time of day is easier to read than daily numbers taken at random times.
Review it
Before each appointment, look back over the period since the last one:
- How many scheduled doses were logged?
- Were there side effects, and when?
- Which sites were used most?
- How have the measurements moved?
An export helps here. PepVault can export your history as a CSV file to print or share.
Common questions
Is a spreadsheet good enough?
A spreadsheet holds the same data, and for one compound logged once a week it can be fine. It gets harder with several vials, a rotation of sites and reminders. See peptide tracker app or spreadsheet.
How long should I keep the log?
Keep it for as long as it could be relevant to your care. Storage is free, and a long history is more useful than a short one.
Does a log replace medical advice?
No. A log is a record. Decisions about what to take, how much and when belong with a qualified healthcare professional.
