Practical guides on keeping an honest record — what you took, what your body did, and how to bring both to your next appointment. Educational only, never dosing advice.
A diary full of paragraphs tells your provider how a day felt; a decision needs to know how days compare. Here are the five columns that make a side-effect log usable — and the evidence on why the night-before catch-up doesn't count.
Everything you take, the reminders that actually arrive, and what your body did in the same weeks — on one timeline you can hand to your prescriber.
Apple Health and Health Connect share data per type and per direction, store it on your device, and let you revoke any single type — here is exactly how each one works and where the controls are.
Heart-rate variability arrives as a single tidy number that looks like a score — but the healthy adult range is so wide, and the measurement so sensitive to conditions, that only your own rolling trend carries information.
What HRV, resting heart rate and sleep stages actually measure, how much they move in healthy people who changed nothing, and how to tell a real trend from ordinary noise in your own record.
The date on the carton describes a sealed product; the moment a vial is mixed or first punctured, a much shorter clock — the beyond-use date — takes over.
Reconstitution is four divisions: vial strength into diluent volume gives a concentration, and that concentration turns an amount into a volume and then into syringe units — shown with illustrative numbers so you can check it.
A practical guide to the part nobody teaches: cold chain and what a left-out vial really means, aseptic technique at a kitchen table, single vs multi-dose vials, site rotation, sharps disposal and what "research use only" actually signals.
Injected testosterone is a slow-release depot, not a steady drip: the ester chain sets how fast it empties, which is why levels peak and fall between injections and why the timing of a lab draw changes the number.
Total testosterone, free testosterone and bioavailable testosterone describe the same blood three different ways — and SHBG, the assay and the time of the draw decide how far apart they land.
What to record on testosterone, menopausal hormone therapy and thyroid medication — and why the timing of a blood draw changes the number more than almost anything else.
Compounded GLP-1 vials are labelled in mg/mL, insulin syringes are marked in units and prescribers speak in milligrams — here is how those three scales relate, and why the same amount of drug is a different volume at a different concentration.
Week three on an unchanged GLP-1 schedule is not the same as week one — the FDA labels for semaglutide and tirzepatide explain why levels keep climbing for about a month, then stay for weeks after the last injection.
A GLP-1 moves slowly enough that no single day tells you much. Here are the six things worth writing down each week, why those six, and how to read what you end up with.
