Peptide, GLP-1 & TRT Calculators

Calculate reconstitution volumes, BAC water ratios, and injection amounts for research peptides.

Per-component amounts from the ratio a blend vial publishes, and what a draw delivers of each.

What one actuation delivers and how many a bottle holds, from your device's own volume.

How a compound accumulates from its half-life and your schedule, for every compound Prof. Peptide can cite.

The published half-life for each compound, with the source it came from.

How many doses a vial holds, and how long that lasts at a given dose and frequency.

Discard dates from a product's own label, plus the diluent clock you supply.

A dose in milligrams to the unit mark on a U-100 insulin syringe.

A unit mark on a U-100 insulin syringe to a dose in milligrams.

Insulin syringe units to millilitres — 100 units to the millilitre, whatever is in the vial.

Millilitres to insulin syringe units, the reverse of the same U-100 definition.

Somatropin between milligrams and international units, and an IU dose on a U-100 syringe.

What one dose costs at each vendor after Prof. Peptide’s code, from whole vials and dated prices.

Reconstitution math for BPC-157, worked for the vial sizes vendors actually sell.

Reconstitution and dose math for semaglutide, tirzepatide and retatrutide.

Reconstitution math for Retatrutide, worked for the vial sizes vendors actually sell.

Reconstitution math for Tirzepatide, worked for the vial sizes vendors actually sell.

Reconstitution math for Semaglutide, worked for the vial sizes vendors actually sell.

Reconstitution math for Cagrilintide, worked for the vial sizes vendors actually sell.

Semaglutide, tirzepatide, retatrutide and cagrilintide compared on accumulation.

Accumulation at the label's approximately one-week half-life.

Accumulation at tirzepatide's published half-life, shown with its citation.

Resting energy by Mifflin-St Jeor, and a daily total. The equation is cited; the multipliers are convention.

A weekly testosterone total split across injections, at the concentration on your vial.

One testosterone dose to a volume and a syringe mark, at your vial's own strength.

Free and bioavailable testosterone by the Vermeulen equation. No reference range — that is your laboratory's.

An HCG dose in USP units to a draw volume and a syringe mark.

Mixing and dosing HCG in USP units, from the 10,000-unit vial the label describes.

A total divided across a number of administrations, in milligrams and on a syringe.

Models no curve: no sourced human half-life exists for the enanthate ester, so the tool refuses rather than drawing one.

How the ADAM screening questionnaire is scored, and why a screen is not a diagnosis.
