When it is all
new.
The first weeks are mostly arithmetic and second-guessing: how much water, how many units, which side last time, and did today already happen. pinning does the arithmetic, records where each one went, and answers the last question by showing you rather than making you remember.
What actually goes wrong
Nothing about a first schedule is hard on its own. It is that four small things all have to be right at once, and three of them are easy to get wrong quietly.
The arithmetic is the visible part — millilitres, micrograms, units on a barrel with two possible scales. The invisible part is the record: whether you did today, which vial it came from, and how much of it is left.
How pinning handles it
The maths is done and shown
Enter the vial size, the water and the dose; the units come back with the working visible. The calculator is public and needs no account — you can check it before deciding anything.
Every dose names its vial and its site
Logging a pin asks which vial and where. That makes the inventory exact instead of estimated, and rotation something you can look up rather than recall.
The guides are free and name nothing
How to reconstitute, what U-100 and U-40 mean, how to store a mixed vial, how to rotate. They cover technique, not what to take.
What it will not do for you
- — It will not tell you what to take, how much, or how often. There is no recommendation engine and the reference section carries no dosing protocols.
- — It is not a medical device and not a substitute for a prescriber.
- — It cannot check that your numbers are sensible — it can only do arithmetic on the ones you give it.
What do I need to track for an injection schedule?
The dose, the date, the site and which vial it came from. The first three are obvious; the fourth is what makes the inventory accurate later, and it is the one people leave out.
Do I need an account to use the calculator?
No. The reconstitution calculator is public and works without signing in, and its result is a link you can send to yourself or anyone else.
Does the app tell me what dose to take?
No, and it is built so it cannot. It records what you did and does the arithmetic you would otherwise do on paper.
