The free, browser-based Peptide Calculator for Pets converts a vet-provided dose into an exact syringe draw for dogs and cats, with supply tracking and dosing schedules
Frisco, TX (PRUnderground) July 7th, 2026
Project Biohacking today announced the launch of the Project Biohacking Peptide Calculator for Pets, a free, browser-based tool that converts a veterinarian-provided peptide dose target into an exact, measurable syringe draw for dogs and cats. The tool is available now, requires no account, and runs in any modern web browser.
The Project Biohacking Peptide Calculator for Pets takes a dose target in micrograms per kilogram, the pet’s weight, the vial size, and the reconstitution water volume, then calculates the solution concentration in micrograms per milliliter and the exact number of units to draw on an insulin syringe. The tool converts an existing dose target into a volume; it does not recommend a dose, and it directs users to follow guidance from a licensed veterinarian.
Advanced features
The Project Biohacking Peptide Calculator for Pets combines dose conversion, visualization, supply forecasting, and scheduling in a single workflow:
- Converts a veterinarian-provided dose target (mcg/kg) into a measurable syringe draw for dogs and cats.
- Species selection for dogs and cats, with weight entry in kilograms or pounds and Small, Medium, Large, and Giant size categories.
- Support for five named research peptides: BPC-157, TB-500, GHK-Cu, Pentosan (PPS), and KPV, plus a custom peptide option.
- Dose tiers of Low, Mid, and High that adjust automatically to the selected peptide, plus a custom microgram-per-kilogram input.
- Vial-size presets of 2 mg, 5 mg, 10 mg, 15 mg, and 20 mg, and water volumes of 1 ml, 2 ml, and 3 ml, each with custom values.
- Subcutaneous or oral administration route selection.
- Automatic concentration calculation in micrograms per milliliter, a total-dose readout in micrograms, and a units-to-draw result for 0.3 ml (30 units), 0.5 ml (50 units), and 1.0 ml (100 units) insulin syringes with a dynamic syringe visualization.
- An optional cycle-days input that totals the peptide needed based on the selected dosing frequency.
- Supply tracking that shows doses used, doses remaining, percent remaining, total doses in a vial, and an estimated days-of-supply figure.
- A dosing schedule with nine frequency options (from once daily to once weekly, including five-days-per-week and custom variants), plus start date, time of day, and optional cycle end date, exportable as a downloadable calendar (.ics) file.
- Advanced options to adjust current weight, target dose, and doses used for more precise tracking.
“Most peptide calculators ignore animals entirely and stop at a single conversion,” said Jeff Nunn, founder of Project Biohacking. “The Project Biohacking Peptide Calculator for Pets covers the full planning workflow (concentration, units to draw, supply, and schedule) in one free tool, so a dog or cat owner working from a veterinarian’s dose can map an entire cycle instead of recalculating every dose.”
A connected research resource
The calculator connects to the Project Biohacking Peptide Vendor Directory, an editorial resource that independently reviews and rates research peptide vendors on a five-star scale, where five stars is the highest rating, so users can compare suppliers side by side. Rather than a simple listing, each vendor earns an overall star rating after being evaluated against a consistent set of criteria, and is re-reviewed as its sourcing and testing practices change over time.
The rating system weighs the factors that matter most for research-grade sourcing: independent third-party laboratory testing, the availability and transparency of certificates of analysis (COAs), supply-chain and manufacturing transparency, product range and catalog depth, pricing, and shipping and fulfillment reliability. A vendor’s star rating reflects its performance across these measures, and each profile documents its testing and COA practices and publishes current, verified coupon codes where available. The directory currently profiles nine suppliers, including Limitless Biotech, BioLongevity Labs, Ascension Peptides, Peptidology, and Rejuvatide Peptides.
Project Biohacking presents the calculator for educational and research-use reference only. The tool’s built-in notice states that it does not determine what dose a pet should receive, is not veterinary advice, and that users should consult a licensed veterinarian and independently verify all calculations before use.
The launch expands the resource library at Project Biohacking, which publishes educational material on peptides, biohacking tools, and related research resources.
Frequently Asked Questions
Is the Project Biohacking Peptide Calculator for Pets free? Yes. The Project Biohacking Peptide Calculator for Pets is free to use, runs in any modern web browser, and does not require an account or a download.
What does the Project Biohacking Peptide Calculator for Pets do? It converts a veterinarian-provided peptide dose into an exact number of units to draw on an insulin syringe for dogs and cats. It calculates solution concentration, shows a syringe visualization for 0.3 ml, 0.5 ml, and 1.0 ml syringes, tracks vial supply with an estimated days-of-supply figure, and builds a dosing schedule that exports to a calendar (.ics) file.
Which peptides does the pet calculator support? It supports BPC-157, TB-500, GHK-Cu, Pentosan (PPS), and KPV, plus a custom option, using Low, Mid, and High dose tiers that adjust to the selected peptide or a custom microgram-per-kilogram value.
Where can I find reviewed research peptide vendors and coupon codes? The Project Biohacking Peptide Vendor Directory rates nine research peptide vendors on a five-star scale, where five stars is the highest rating. It scores each vendor on third-party testing, COA sourcing, supply-chain transparency, product range, pricing, and shipping, and publishes verified coupon codes where available.
How does the Project Biohacking Peptide Vendor Directory rate vendors? Each vendor receives an overall rating on a five-star scale, where five stars is the highest. Ratings reflect independent third-party testing, certificate of analysis (COA) sourcing, supply-chain transparency, product range, pricing, and shipping reliability, and vendors are re-reviewed as their practices change.
Can the calculator tell me what dose my pet should take? No. The tool only converts an existing, veterinarian-provided dose target into a volume. It is not veterinary advice, and dose selection should come from a licensed veterinarian.
