The calculator

Enter any two of the three numbers and the calculator returns the third. Pick a vial from our catalogue and the mass fills itself in. Choose a blend and it splits the answer per component.

No account, no email, nothing to install.

This is arithmetic, not a dosing recommendation. It converts mass and volume into concentration and back. It says nothing about what to do with the result. Boreal Peptides publishes no dosing, no protocols and no administration guidance, here or anywhere else on this site.

The arithmetic

What the sum actually is

One identity, solved three ways:

concentration = mass divided by volume

That is the entire tool. A 10 mg vial reconstituted with 2 mL of bacteriostatic water is at 5 mg per mL, because 10 divided by 2 is 5. Run it backwards and a 10 mg vial you want at 5 mg per mL needs 2 mL of water.

Everything else on this page is presentation. The arithmetic is the job, and it is small.

The line

Why we do not turn this into a dose

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

Ours does not, and will not. Boreal Peptides publishes no dosing, no protocols, no cycles, no stacks and no administration guidance, anywhere, for any compound, at any strength. A tool that turns a concentration into “draw this many units” is administration guidance wearing a calculator’s clothes, and adding it here would contradict every other page on this site.

Everything we sell is supplied for laboratory research use only. Nothing is approved for use in a person or an animal. The full statement is on our research use disclaimer.

If that makes this tool less convenient than a competitor’s, that is the trade, and we would rather tell you why than quietly leave the box out.

Blends

Blends are not one compound

This is the mistake the tool exists to prevent.

An 80 mg four-compound vial is not 80 mg of one thing. Treating it that way gives you a concentration figure that is right for the vial and wrong for every compound in it.

Choose a blend in the calculator and it splits the result. The component masses come from each blend’s own product page, and they add up to the vial mass, which the tool states back to you so you can check it:

BlendTotalWhat is in it
KLOW Blend80 mgTB-500 10 mg, BPC-157 10 mg, KPV 10 mg, GHK-Cu 50 mg
GLOW Blend70 mgBPC-157 10 mg, GHK-Cu 50 mg, TB-500 10 mg
CJC-1295 and Ipamorelin10 mgCJC-1295 without DAC 5 mg, Ipamorelin 5 mg

There is a second thing worth knowing about these two. The KLOW and CJC-1295 certificates carry identity data describing a single component rather than the mixture, so we do not claim either was assayed as a finished blend. Our blends page sets out exactly what the paperwork says.

Exclusions

Two vials are missing from the list, on purpose

HGH is sold in international units rather than milligrams. A milligrams per millilitre calculation does not describe it, and a conversion between the two depends on a factor that varies by preparation. Rather than pick one, we left it out.

PT-141 is left out because its strength attribute in our own store disagrees with every other record we hold for it. That contradiction is on our list to resolve. Until it is, putting a number we doubt into a calculator would be worse than leaving a gap.

Everything else we stock is in the dropdown, with the strengths the product pages actually sell.

Its limits

What the calculator does not tell you

A concentration is a number about a solution. It is not a statement about the material in the vial, and it is not a safety result.

  • It does not tell you the vial contains what the label says. That is what a third-party certificate is for, and 17 of our 31 products have one while 14 do not.
  • It does not account for the small volume the powder itself occupies once dissolved. For the masses and volumes used here that displacement is very small, but it is not zero, and the calculator does not model it.
  • It says nothing about sterility, endotoxin, heavy metals or stability. None of those is covered by any assay we hold.
What you need

Reconstitution supplies

The diluent this calculator assumes is bacteriostatic water, which we sell in 3 ml and 10 ml. Everything else in that category is on the reconstitution supplies page.

We do not publish a reconstitution procedure, for the reason set out above.
