InjectBuddy turns dosage calculations into simple, accurate outputs. Clean mg→mL conversions, syringe visuals, and schedules that actually make sense.

People managing testosterone therapy, peptides, or general hormone optimisation at home need accuracy, not improvisation. Most users are given a vial, a number, and a loose schedule—then left to calculate mg-to-mL conversions, injection frequency, syringe sizing, and day-to-day dosing without clear guidance. InjectBuddy was built to remove that uncertainty.
The Testosterone Dosage Calculator provides structured dosing maths and a realistic syringe visual so users can see exactly what they should be drawing. The Peptide Calculator handles reconstitution and injection volumes consistently, preventing common mistakes caused by incorrect dilution maths.
Supporting tools like the BMI Calculator and the Free Testosterone Calculator exist because hormones don’t operate in isolation. BMI influences metabolic health, and free testosterone gives a clearer picture of hormonal balance than total levels alone.
To complement the tools, the Guides & Learning Center consolidates the information users usually have to piece together from forums and conflicting advice—bloodwork basics, TRT dosing concepts, peptide fundamentals, and injection-technique safety.
Simply put, InjectBuddy exists to bring structure, accuracy, and clarity to hormone management without ads, noise, or guesswork.
