BENCH: Peptide Calculator

BENCH is a free, private calculator and logbook for people working with research peptides and GLP-1 compounds. It does the reconstitution math for you and keeps a tidy record of your vials and entries - no ads, no tracking, and nothing sold to anyone.

FREE MEANS FREE
No paywall before your first calculation. No "3 peptides, then pay" cap. No subscription, no unlock fees, no ads - ever. The calculator, the reference library and the Decoded research reader don't even need an account.

RECONSTITUTION CALCULATOR
Tell BENCH your vial size and the dose you want. If the vial isn't mixed yet, BENCH picks how much bacteriostatic water to add so your draw lands on a clean, easy-to-read number of units. Already mixed? Enter the BAC water you used and get the exact units to draw, shown on a visual U-100 syringe. Switch between mcg and mg with a tap, and half-unit syringes are supported.

COVERS WHAT YOU ARE ACTUALLY USING
A searchable reference library of 89 compounds, brand names included - GLP-1 compounds such as semaglutide, tirzepatide, retatrutide and cagrilintide; healing and recovery peptides such as BPC-157, TB-500 and KPV; growth-hormone secretagogues such as CJC-1295, ipamorelin and sermorelin; plus cognitive, longevity and cosmetic compounds. Everything is clearly marked reference-only.

VIAL TRACKER AND DOSE LOG
Save a vial and watch its freshness clock, how much solution is left and how many doses remain. Log what you draw in one tap and see your full history. Set a schedule - daily, every other day, chosen weekdays, or cycles of days on and off - and BENCH shows what is due today, tracks your streak and adherence, and can send an optional reminder at the hour you pick.

DECODED - RESEARCH IN PLAIN ENGLISH
Readable, citation-backed interpretations of real published studies, so you can see what the literature actually says rather than what a forum post claims.

READ A CERTIFICATE OF ANALYSIS PROPERLY
An interactive, annotated COA explains purity, assay, sterility, endotoxin and heavy-metal testing in plain English - what each test measures, what a good result looks like, and the red flags worth a second look.

NEW TO THIS?
A plain-English primer explains reconstitution, units and the whole workflow in about sixty seconds. No jargon, no assumed knowledge.

PRIVATE BY DESIGN
- No ads. Ever.
- No third-party trackers or advertising SDKs.
- We never sell or share your data.
- Export everything as JSON, or delete your account in one tap.

IMPORTANT
BENCH is an informational tool for research-use reference and personal record-keeping, and is for adults (18+).
