Five tools

What is here

Five reconstitution calculators. All free, none behind an account or an email form, and all built on the same piece of arithmetic.

The peptide reconstitution calculator is the general one. It carries our whole catalogue, twenty-three compounds with their real strengths and three blends, and it splits a blend per component.

Four are preloaded with a single compound, because the vial strengths differ so much between them that a general tool is a poor fit:

CalculatorVials it knowsThird-party certificate
Retatrutidenine, 5 mg to 100 mgyes, 99.562%
BPC-157three, 2 mg to 10 mgyes, 99.781%
Tirzepatideten, 5 mg to 120 mgno
Semaglutidefive, 5 mg to 50 mgno

That last column is not decoration. Seventeen of our thirty-one products carry a third-party certificate and fourteen do not, and each calculator page says which side its compound falls on.

The arithmetic

The sum they are all doing

concentration = mass divided by volume

Give any of them two of the three numbers and it returns the third. A 10 mg vial with 2 mL of bacteriostatic water is at 5 mg per mL, because 10 divided by 2 is 5.

Everything else is presentation. The arithmetic is the job, and it is small enough to check by hand, which you should be able to do with any tool that gives you a number.

The line

None of them will give you a dose

Almost every peptide calculator online has a box asking what dose you want, and returns a number of units on an insulin syringe.

None of ours does, and none will. Boreal Peptides publishes no dosing, no protocols, no cycles, no titration schedules and no administration guidance, for any compound, at any strength, anywhere on this site. A tool that converts a concentration into “draw this much” is administration guidance wearing a calculator’s clothes.

Everything we sell is supplied for laboratory research use only, and nothing is approved for use in a person or an animal. The full statement is on the research use disclaimer, and the FAQs answer the legal questions directly.

Exclusions

Two vials are missing from every dropdown

HGH is sold in international units rather than milligrams, so a milligrams per millilitre calculation does not describe it.

PT-141 is excluded because its strength data in our own store disagrees with every other record we hold for it. That contradiction is on our list to resolve, and until it is, a preset built on a number we doubt would put that doubt inside a tool.

Both gaps are stated on the calculator pages themselves rather than left for you to notice.

Not built

What we have not built, and why

We checked Canadian search demand before building anything, and several obvious-sounding tools have none.

  • A dosing calculator. There is real demand for one. We will not build it, for the reason above.
  • An HCG calculator. This is the highest-demand compound calculator we measured. We do not sell HCG, and it is named in Health Canada’s 9 April 2026 advisory. A tool for a product we do not stock would be traffic with nothing behind it.
  • Calculators for TB-500, Ipamorelin, CJC-1295, GHK-Cu, MOTS-c, NAD+ and Melanotan 2. Measured demand for each is zero. They are all in the general calculator’s dropdown instead, which is where they belong.
  • A half-life or shelf-life calculator. No measured demand, and both would need stability claims we have no data to support.
Supplies

What you need alongside them

The calculators assume bacteriostatic water as the diluent, which we sell in 3 ml and 10 ml. The rest is on the reconstitution supplies page.

We publish no reconstitution procedure, for the same reason we publish no dosing.
