A calculator site built around checkable math.

CalcPeptides is an independently operated calculator and reference site for peptide reconstitution, concentration, and unit-conversion arithmetic. The public contact address for the site is hello@calcpeptides.com.

The site exists because peptide calculator pages can be confusing when they hide formulas, mix units, or blur arithmetic with advice. The goal here is narrower: show the inputs, show the formula, explain the unit conversion, and make the result easier to audit.

Who maintains the site

CalcPeptides is maintained by its publisher as a free educational tool. It is not a clinic, pharmacy, compounding provider, supplement seller, peptide vendor, or medical practice. The site does not sell peptides or recommend sources.

What CalcPeptides covers

The current review-ready focus is reconstitution math: vial mass, final volume, concentration, microliter volume, and common mg/mcg/mL/uL unit checks. Other experimental calculators may exist on the site, but the main reviewed content is the calculator-first reconstitution reference cluster.

What CalcPeptides does not do

CalcPeptides does not provide medical advice, veterinary advice, dosing recommendations, treatment plans, administration instructions, product validation, sourcing guidance, sterility review, legal advice, or safety clearance. Calculator output is arithmetic only.

Review and corrections

Core pages are reviewed when calculator logic changes, when unit explanations are updated, when cited references change, or when a user reports unclear math. If something looks wrong, send the page URL, the values entered, the result shown, and the expected arithmetic through the contact page.

Correction priority goes to issues that could affect calculator output, unit interpretation, formula wording, or the boundary between arithmetic and advice.

Reference anchors

Unit conventions follow standard metric relationships: milli means one-thousandth, micro means one-millionth, 1 mg equals 1000 mcg, and 1 mL equals 1000 uL. See NIST SI prefix guidance. Medical-adjacent GLP-1 pages, when present, are intentionally limited and reference FDA safety communications rather than providing treatment guidance.
