The tools
The math you should not be doing at 2am
Free and cited, no account needed. Each tool does one job and shows its work.
Reconstitution calculator
Turn a vial, bacteriostatic water, and a target dose into exactly how many units to draw on your syringe.
Open the tool ->Methylene blue dosage calculator
Convert a percent solution into mg/mL, mg per drop, and the volume for a dose. 1% = 10 mg/mL.
Open the tool ->GLP-1 titration calculator
Lay out a week-by-week dose-escalation timeline. Load the semaglutide, tirzepatide or retatrutide schedules, or build your own from a start dose, step, and max.
Open the tool ->NAD+ reconstitution calculator
Mix a 500 or 1000 mg NAD+ vial and get the concentration, units to draw, and how many doses the vial holds.
Open the tool ->Free testosterone calculator
Estimate free and bioavailable testosterone from total T, SHBG, and albumin, by the Vermeulen 1999 method.
Open the tool ->TRT draw-volume calculator
Turn a testosterone dose in mg and your vial concentration into the volume and syringe units to draw.
Open the tool ->Testosterone ester half-life visualizer
See how an ester stacks up and swings between injections. An illustrative relative-level model, not a blood level.
Open the tool ->Dog peptide dosage calculator
Turn a dog's weight and a mcg/kg figure into micrograms per day and units to draw. Unit math only, not a veterinary dose.
Open the tool ->Storage & stability chart
How long each peptide lasts - lyophilized vs reconstituted, at room temp, in the fridge, and frozen. Every figure tagged by how strong its evidence is.
Open the tool ->Interaction checker
Check methylene blue against SSRIs, SNRIs, MAOIs, and other serotonergic drugs. Serotonin-syndrome risk, cited.
Open the tool ->Grade checker
Pharmaceutical, research, or aquarium grade? Find out which methylene blue you have and whether it is fit to ingest.

Tracking your protocol
Best peptide tracker apps
A vendor-neutral roundup of the peptide and GLP-1 trackers, what each does well, and where it falls short.
Read ->How to log doses
What to record for each shot, how to track a vial from full to empty, and the mistakes that make a log useless.
Read ->Tracker vs spreadsheet
Where a spreadsheet genuinely works for a protocol, where it breaks, and how to choose between the two.
