How it works
From two numbers to a finished dose
Nettle carries you from reconstitution math through drawing, logging, reminders, and weigh-ins — one flow, not five separate screens.
Start with what you already know
You enter the vial's strength and the dose you want. Instead of asking you to guess a water volume first, Nettle solves for it — choosing an amount that lands your draw on a clean, round-unit mark on a standard syringe.
That water volume, and the resulting draw, are what the rest of the walkthrough is built around — the diagrams and captions in the next step use your actual numbers, not a generic example.
The reconstitution guide
Nine steps, captioned with your numbers
Each step pairs a photo reference with the specific volume, count, or instruction your calculation produced — so you're never translating a generic guide into your own math mid-injection.
Swab the BAC water vial
Wipe the rubber stopper with an alcohol swab and let it dry before drawing.
Draw the BAC water
Draw the exact volume Nettle calculated for you — shown as a caption under this step, with multi-draw instructions if the volume needs more than one syringe fill.
Swab the peptide vial
Wipe the peptide vial's stopper the same way, and let it dry.
Insert the needle
Insert at an angle against the rubber stopper, bevel up, to keep the puncture clean.
Inject the water
Push the plunger slowly, aiming the stream along the inside wall of the vial rather than directly at the lyophilized powder.
Swirl, don't shake
Gently swirl the vial in a circular motion until the powder is fully dissolved. Shaking can damage the peptide — a common-mistake callout flags this directly on this step.
Inspect the solution
Check that the liquid is clear, with no visible particles or cloudiness, before drawing your dose.
Draw your dose
Draw to the unit mark Nettle calculated for the dose you entered at the start.
Inject
Administer per your prescriber's instructions on site and technique.
After the injection
The flow keeps going — it doesn't stop at the dose
Logging, reminders, and weigh-ins are part of the same flow, not separate tabs you have to remember to open.
One tap to log
The dose, volume, and units you just drew are pre-filled. Confirm the injection site and any side-effect tags, and it's saved to your history.
Reminders per vial
Nettle sets your next-dose reminder automatically, scoped to that specific vial — so two active vials of the same peptide can run on independent schedules.
Trends, not decisions
An optional weigh-in surfaces patterns worth bringing to your provider. Nettle never uses that data to suggest, adjust, or recommend a dose.
Set up your first vial in under two minutes.
