Peptide & GLP-1 · calculator + tracker
Never
second-guess
a dose.
Enter your vial, your BAC water, and the dose your provider gave you — get the exact syringe units to draw, on any scale. Transparent math you could do by hand, plus a tracker that never loses your vials.
Based on the values you entered
Educational information and a math tool only — not medical advice, a dose recommendation, or an endorsement of peptide use. Consult a licensed healthcare provider before starting, stopping, or changing anything.
Reconstitution
Transparent math on your values
Syringe concentration
Standard insulin syringes are U-100 (1 unit = 0.01 mL); U-40 is a less-common concentration — check your syringe.
Based on the values you entered
Enter your vial size and BAC water to see the math.
This tool converts a dose you have already been given into syringe units — it does not set your dose, confirm a peptide is appropriate for you, or replace a clinician. Get your target dose and protocol from a licensed provider. Presets are example inputs, not recommendations — enter your own values.
Your values, your math
Every number comes from what you type — vial mg ÷ BAC mL → units on your syringe scale. Fully reviewable, nothing hidden.
Bulletproof tracking
Save vials, log every dose, rotate injection sites, watch trends. Engineered so your data never disappears — the category's #1 complaint.
Neutral, cited facts
Half-life, FDA status, what studies exist — third-person and sourced. We convert a dose you were already given; we set none.
