💰 Peptide Cost Calculator
Calculate cost per dose, weekly spend, monthly budget, and full cycle cost — with automatic 28-day waste adjustment.
True Cost of a Peptide Protocol
The vial price is just the starting point. Your real cost per dose depends on how many doses fit in the vial, whether the vial expires before you finish it, and how many vials a complete cycle requires. This calculator builds the full financial picture: cost per injection, weekly spend, monthly budget, and total cycle cost — adjusted for any peptide wasted to the 28-day expiry window.
Budget tip: buying larger vials (e.g. 10 mg instead of 5 mg) typically reduces cost per dose by 30–50% — provided you can use the entire vial within 28 days. Run both vial sizes through this calculator to find the true cost-per-dose for each.
5 mg BPC-157 vial @ $45, dosing 500 mcg once daily for a 12-week cycle.
- Doses per vial: 5,000 ÷ 500 = 10 doses
- Cost per dose: $45 ÷ 10 = $4.50
- Total doses needed: 12 × 7 = 84 injections
- Vials required: 84 ÷ 10 = 9 vials = $405 total

Cost Calculator — Frequently Asked Questions
How do I get the lowest cost per dose?
Buying larger vials is the most effective cost reduction — a 10 mg vial at 1.8× the price of a 5 mg vial cuts your cost per dose by nearly half, provided you use the full vial within 28 days. Bulk ordering (3–6 month supply of unreconstituted vials) often comes with volume discounts. Also compare suppliers: the same peptide can vary 3–5× in price across research vendors. Always verify third-party HPLC testing before choosing on price alone.
Why does the calculator adjust for 28-day expiry?
If your vial lasts longer than 28 days at your dose frequency, the peptide in the vial past day 28 is unusable — it must be discarded. That waste is a real cost. This calculator factors in how many doses you can actually use within 28 days and shows you the true cost-per-usable-dose. A vial that looks cheap per mL may be expensive per effective dose if most of it gets wasted.
What consumable costs should I budget for beyond vials?
A complete peptide protocol requires: bacteriostatic water (~$8–15 per 30 mL vial), insulin syringes (~$0.10–0.30 each), alcohol prep swabs (~$0.02–0.05 each), a sharps disposal container, and refrigerator space. For a 12-week protocol with daily injections, budget $30–60 for consumables. For stacks running multiple peptides simultaneously, this scales proportionally. Include these in your total cost when comparing protocols.
Is it more cost-effective to stack two peptides than run them individually?
From a cost-per-outcome perspective, synergistic stacks can deliver better results at lower individual doses than either peptide at full dose alone. For example, BPC-157 + TB-500 stacked at half doses may outperform either alone at full dose for tissue repair, at a similar total cost. Run each peptide through this calculator separately and add the totals to see your combined monthly budget for any stack.
