BENCH: Peptide Calculator

BENCH is a free, private peptide calculator and logbook for people working with research peptides. It does the reconstitution math for you and keeps a tidy record of your vials and entries — with 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 89-compound 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 your vial isn't mixed yet, it picks how much bacteriostatic water to add so your draw lands on a clean, easy-to-read number of units. Already mixed? Enter what you used and get the exact units to draw — shown on a visual syringe.

BUILT FOR NEWCOMERS AND VETERANS
A plain-English "new to this?" primer explains reconstitution and units in 60 seconds. A reference library of 89 compounds (with brand-name search) gives you commonly-cited context at a glance — clearly marked reference-only.

YOUR PRIVATE BENCH
Save your vials and watch a freshness clock and how much is left. Log what you draw and see your history and a simple journey view of your own activity. Everything is behind a private login.

DECODED — RESEARCH IN PLAIN ENGLISH
Readable, citation-backed interpretations of real published studies, so you can understand what the literature actually says.

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.
