MOTS-c reaction log for injection-site changes, tiredness and shaky spells
Forum posts rarely keep the details that let a reaction be interpreted. This log records the time since injection, a glucose reading if you have a meter, the vial's lot and how the reaction changed, so a clinician or a MedWatch report has something to work with.
The vial
Product name and seller
Lot number and expiry date
How and when it was mixedliquid used and date reconstituted
How it has been stored since
Injection-site changes
| Date and time | Site | Size of redness or swelling | Pain or burning | How long it lasted | Photo taken? |

Shaky, sweaty or tired spells
A glucose reading taken during the spell is what turns a symptom into a measured result.
| Date and time | Minutes since injection | Symptoms | Glucose reading, if measured | What you did | How long it lasted |
