Why these tools exist
Most dosing mistakes aren’t caused by bad intentions—they’re caused by mental math, unit confusion, and inconsistent setups.
InjectBuddy tools are designed to standardise calculations so you can focus on execution, not arithmetic.
Principle
If the math is wrong, the dose is wrong.
Core calculators
-
Peptide calculator
Convert mg or mcg into syringe units based on vial strength and dilution. -
Testosterone dosage calculator
Plan weekly dose, injection frequency, and per-injection volume. -
Peptide reconstitution calculator
Choose dilution volumes and see resulting concentration instantly.
Supporting tools
-
Syringe visual guides
Visualise insulin syringe markings to reduce draw errors. -
Injection frequency planners
Compare weekly vs every-N-day injection schedules. -
Unit conversion helpers
Reduce mg, mcg, mL, and IU confusion.
How to use these tools correctly
- Confirm vial strength before entering values
- Understand dilution before trusting outputs
- Match syringe type to the calculator
- Recheck numbers if anything looks unexpected
Rule
Tools support understanding—they don’t replace it.
Common calculator mistakes
- Entering total vial amount instead of per-mL concentration
- Confusing mg and mcg
- Using the wrong syringe scale
- Changing dilution mid-vial without recalculating
Pattern
Bad inputs produce confident-looking wrong outputs.

Key takeaways
- Calculators reduce math errors—not judgment errors.
- Correct inputs are more important than fancy outputs.
- Consistency beats recalculating every injection.
- Understanding always comes first.
