How the cost per shot is worked out
Every peptide cost comes down to how many shots one vial gives you. Convert the vial and the dose to the same unit, then:
cost per shot = (vial price ÷ shots per vial) × (1 + waste %) + supplies per shot
monthly cost = cost per shot × shots per week × 4.345
Example: a $60 vial with 10 mg, dosed at 250 mcg (0.25 mg), gives 40 shots. That's $1.50 of peptide per shot. Add 5% waste and $0.35 of supplies and you're at about $1.93 a shot, or roughly $58 a month taken daily. One average month is 4.345 weeks (52.14 weeks ÷ 12).
Adding up a whole stack
Run the calculator once for each compound and add the monthly totals. A stack is rarely one number: a daily peptide, a twice-weekly one and a weekly GLP-1 each burn through vials at their own pace, and step-up dose plans raise the cost as you go. That's where a running tracker beats a one-off calculation. PepKeep counts each vial down as you log doses and shows your spend per shot, per month and per year across the whole stack.

Questions
How do I calculate the cost of one peptide shot?
Divide the vial amount by your dose to get shots per vial, then divide the vial price by that number. Add a few percent for waste and the cost of the syringe and alcohol pad. A $60, 10 mg vial dosed at 250 mcg gives 40 shots, about $1.50 each before supplies.
How do I work out my monthly peptide cost?
Multiply the cost per shot by the number of shots per week, then by 4.345 (the average number of weeks in a month). Do this for each compound and add them up for the whole stack.
Does the water I add change the cost?
No. Bacteriostatic water changes the concentration, so it changes how many units you draw, but not how many doses are in the vial. The cost per shot depends only on the vial amount, your dose and the price. Use the reconstitution calculator for the units.
Why does my real spend come out higher than the math?
Waste. Syringe dead space, a vial that passes its use-by date before it's finished, a spilled vial and shipping all add up. Set the waste allowance to match your experience, and track actual vial use to see the true number.
Is this calculator medical advice?
No. It does arithmetic on the numbers you enter. It doesn't recommend compounds or doses.
