Free Peptide Tools & Calculators

Does: Calculate cost-per-mg and cost-per-dose across suppliers for the same peptide. Enter vial mg, vial price, and your daily dose — get monthly cost, yearly cost, and supplier ranking. Pulls current Peptide Partners and Orbitrex pricing where available.

Useful because: Most peptide users don't calculate the true cost of a protocol until they're three months in. Cost-per-mg varies 2–4× across suppliers for identical peptides. This tool surfaces that before purchase.

Does: Build a weekly injection schedule across multiple peptides. Set each peptide's frequency (daily, M/W/F, weekly), dose, and cycle length — get a visual 8–12 week calendar showing every injection day and when to cycle off.

Useful because: Multi-peptide protocols get hard to track manually. Wolverine stacks are daily. CJC-1295 DAC is weekly. Tirzepatide is weekly with titration. A single-view planner prevents missed doses and wrong-day injections.

Does: Generate the full titration schedule for Tirzepatide, Semaglutide, or Retatrutide based on FDA-approved or clinical trial titration timelines. Enter your starting vial size and water volume — get every escalation step with exact syringe units for each phase.

Useful because: GLP-1 titration is the single most common peptide workflow on the web, and also the most commonly miscalculated. Every phase changes the syringe units, and users routinely skip or double-dose during escalation. A dedicated titration tool solves this cleanly.

Does: Given a vial size and a target syringe unit draw (e.g., "I want every dose to be exactly 10 units"), calculate the exact BAC water volume required. Reverses the standard reconstitution math.

Useful because: Most dosing errors come from awkward volumes — 7.5 units, 12.5 units, non-round fractions. Forcing a clean 10, 20, or 25 unit draw by adjusting water volume eliminates that error class.

Does: Check whether two or more peptides can be co-reconstituted in the same vial, co-injected separately, or should be kept apart entirely. Flags stability conflicts (e.g., short-stability peptides that limit the combined vial's usable window) and pathway conflicts (e.g., antagonistic mechanisms).

Useful because: Community blend protocols often combine peptides that shouldn't actually share a vial — either because the shortest-stability component limits the whole blend, or because the pathways conflict. This tool surfaces those conflicts before reconstitution, not after.

Does: End-to-end cost projection for a named protocol. Pick a stack (Wolverine, GLOW, KLOW, CagriSema, full GLP-1 titration), select a supplier, and get total cost for a full cycle including vials, BAC water, syringes, and alcohol swabs.

Useful because: Pulls together the cost calculator and cycle planner into one answer: "How much does a 12-week GLOW cycle actually cost?"
