Doses per vial: floor((5 mg × 1000) ÷ 250 mcg) = 20

Cost per dose: $40.00 ÷ 20 = $2.00

Weekly: $2.00 × 14 = $28.00

Monthly: $28.00 × (30 ÷ 7) = $120.00

Annual: $28.00 × 52 = $1456.00

Assumptions

Vial prices are user-entered estimates and vary by vendor
Monthly = 30 days (4.286 weeks); annual = 52 weeks
Assumes full usable volume per vial (no overfill or waste)
Does not include shipping, supplies, or consultation costs
Prices change frequently — verify with your provider

How This Calculator Works

Flow diagram showing how the cost calculator works — Cost calculation flow — from vial price to monthly budget

The calculator divides your vial price by the number of doses per vial to find cost per dose, then multiplies by your weekly frequency. Monthly cost uses a 30-day month (4.286 weeks); annual cost uses 52 weeks. All formulas are visible in the “Show the math” section.

Assumptions & Limitations

Vial prices are user-entered estimates — actual prices vary by vendor, region, and purchase quantity.
Assumes full usable volume per vial with no waste from reconstitution or dead volume in syringes.
Does not include ancillary costs (BAC water, syringes, shipping, provider consultations).
Preset prices are approximate market averages for research-grade peptides and may not reflect your actual cost.
For compounding pharmacy pricing (often insurance-eligible for semaglutide/tirzepatide), consult your provider directly.

Frequently Asked Questions

How accurate are these cost estimates?

The calculator performs exact math on the numbers you enter. Accuracy depends on your inputs — vial prices vary widely by vendor, purity, and region. Treat results as estimates for budgeting purposes, not quotes.

Why do peptide prices vary so much between vendors?

Pricing differences reflect manufacturing quality, purity testing (HPLC), source country, brand reputation, and whether the product is sold for research or through licensed compounding pharmacies. Higher-priced vendors typically provide third-party certificates of analysis.

Does the monthly cost include everything I need?

No. This calculator estimates peptide vial costs only. Additional expenses may include bacteriostatic water, syringes, alcohol swabs, sharps disposal, and healthcare provider consultations. These typically add $10–30/month.

How can I reduce peptide costs?

Common approaches include purchasing larger vial sizes (lower cost per mg), buying in multi-vial kits, choosing vendors with volume discounts, and optimizing dose (some protocols start low and titrate up only as needed). Always prioritize quality and purity over price.
