Free peptide calculators and reference

Peptide calculators that show the draw, not just the number

Reconstitution math with the pen or syringe drawn to scale, multi-compound timing, decay curves and cost. Everything runs in the browser, and nothing you type leaves the page unless you sign in to sync your saved protocols.

Reconstitution

Vial content, water added, amount per draw — the syringe or pen updates as you type.

Vial label

Paste into label-printer software. Nothing is sent anywhere.

The concentration is the line worth having: a vial two weeks later carries no record of how much water went into it.

Other tools

Protocol builder

Several compounds at once: what lands together, how durations line up, vials for the plan.

Half-life

Decay curves, and how much a schedule accumulates read off the curve itself.

Cost

Per draw, per week and across a protocol, counting what stays in part-used vials.

What is covered

21 compounds carry typical vial sizes, published research amounts and a half-life for the decay model. Where the literature is thin, the entry says so instead of implying a precision it does not have.
