1 · Pick your compound Fills the typical vial size, dose, and schedule from its profile. Adjust anything after. 2 · Peptide in your vial (mg) Printed on the vial label. 3 · Your dose (mcg) From the compound's protocol. 1 mg = 1,000 mcg. 4 · Doses per week Daily = 7. Twice weekly = 2. Water (ml) auto Water never changes the dose — only how big the draw is. Auto picks an amount that makes each draw an easy-to-read ~20 units.

How the math works

Concentration = peptide (mcg) ÷ water (ml). Your draw = target dose ÷ concentration. On a standard U-100 insulin syringe, 1 ml = 100 units, so units = draw (ml) × 100.

Does body weight change the dose?

Mostly no — and it surprises people. Unlike many supplements, most peptide protocols are flat-dosed: growth-hormone secretagogues saturate their receptor per pulse, so a bigger body doesn't need a bigger signal; the GLP-1 class is titrated by response, not by size. What DOES vary is where you sit inside the published range — a 240-lb competitor running hard typically runs the top of the range where a lighter or newer person runs the middle. A couple of exceptions trend weight-scaled in the literature (IGF-1 LR3 is often quoted per kg, and TB-500 loading is sometimes sized to body mass). The Supply Builder's Standard / Full-strength toggle handles exactly this — it sizes an entire program's supply for whichever end of the range fits you.

Always confirm your syringe type. All output is arithmetic on your inputs — it is not a dosing recommendation.
