Reconstitution calculator · Peptide library · Simple tracker
Peptide research, calibrated.
A reconstitution calculator that does the math, a peptide library that cites every claim, and a tracker that remembers what you took. Protocols pulled from published research and the way people actually dose them on Reddit.
Free to use. No medical advice. Always confirm doses with a clinician.
How much water should I add?
You know your dose, find the right mix.
Look on the vial label. It's the total amount of peptide before mixing.

All options give you 10 doses per vial.
Highlighted rows use 1.0–2.0 mL of water, the most practical mix for most peptides and syringes.

Calculate without the math.
Start with a new vial or an existing mix: two tools that cover both sides of the calculation.
A peptide library that cites everything.
Every claim links to the study behind it. Community protocols cite the Reddit threads they came from. Every page shows when it was last reviewed.
Track your protocol, not your inbox.
Doserr remembers what you took, when, and how much, so you don't have to.
Calibrated, not clinical.
Show the research behind every claim.
Pretend something is settled when it isn't.
Use plain English a beginner can read.
Hide behind jargon to look credible.
Cite community protocols by their actual Reddit thread.
Pretend internet protocols are clinical evidence.
Common questions.
No. The calculator and the peptide library work for everyone. An account lets you save calculations, track doses over time, and save protocols from any peptide page or stack.
