How many units do I draw? Just ask.
mg, mcg, units, U-100, mL. You should not need a math degree to read your own syringe. Tell it your vial, your water, and the dose you and your provider already chose, and it shows the syringe units for those numbers. Free, right here, no account needed.
Presets fill a common vial size and water amount. Always match what is on YOUR label, and get your target dose from your own label or provider.
The mg number printed on the vial label.
How much water you mixed in (or plan to).
From your own label or provider. 1 mg = 1000 mcg.
PRTCL does not recommend, prescribe, or decide doses. This tool only converts the numbers you enter (your vial, your water, and a dose you and your healthcare provider have already chosen) into syringe units. Educational only, not medical advice. Always verify with your provider before acting on it. Using a blend or a stack? The PRTCL app handles multi-peptide math, dose logging, and reminders. Questions about what is normal when mixing? Read the reconstitution guide or start with Peptides 101.
Every health statement in PRTCL links to where it came from: official prescribing information, peer-reviewed research, or published clinical guidance. Anything that could not be cited was left out. And PRTCL never tells you what dose to take. That part stays between you and your doctor.
