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

Start with the reconstitution calculator to find concentration from mass and final volume, use the unit converter to move between amount and volume at a known concentration, or build a reference chart for your own values. The guides explain those calculations with worked examples rather than recommending amounts or protocols.

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

Updates use code-based formula tests and checks of the explanations, units, and links. AI tools assist with development and editing; these checks are not a clinical review or a claim of professional credentials. 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.

Last reviewed

This About page was checked October 12, 2026. Dates on individual tools and guides refer to their own arithmetic or explanation checks, not a site-wide medical review.

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.
