About Pep Formula
A free, independent peptide reconstitution and dosage calculator built for researchers, clinicians, and biohackers who demand accuracy.
What Pep Formula Is
Pep Formula is a free, independent peptide reconstitution and dosage calculator. It was built for researchers, clinicians, and biohackers who need accurate, fast calculations — without signing up, paying, or sitting through an ad-laden experience.
Every calculation on this site happens entirely in your browser. No data is transmitted to any server. Your vial sizes, BAC water volumes, and dosage inputs never leave your device. We built it this way intentionally — privacy is not an afterthought here.
The tools cover the full workflow: reconstitution concentration, injection volume, syringe unit conversion, and peptide-specific dosing guides. Whether you're working with BPC-157, TB-500, Semaglutide, Tirzepatide, or a dozen other compounds, the math is the same — and Pep Formula handles it correctly every time.
Who Built It
Pep Formula Editorial Team
Research Tool Development · Peptide Pharmacology · Clinical Reference
Pep Formula was created by a team with backgrounds in biochemistry, pharmaceutical compounding protocols, and health-tool development. Every calculator formula on this site is cross-referenced against published compounding pharmacy references and verified with known-correct values before launch.
Content is written by people who have worked directly with peptide reconstitution protocols — not generalist writers. The goal is to produce the clearest, most numerically precise reference available for anyone who needs to reconstitute a peptide or calculate a dose.
We update guides when research literature changes, correct errors reported by users within 48 hours, and do not accept sponsored content or paid placements that influence calculation results.
Our Methodology
All calculations are based on standard pharmaceutical reconstitution protocols — the same formulas used by compounding pharmacies and published in clinical reference guides.
Concentration
Once a lyophilized peptide vial is reconstituted with bacteriostatic water (BAC water), the resulting concentration is calculated as:
Injection Volume
To draw the correct volume for a target dose, divide the desired dose by the concentration:
Syringe Units
For insulin syringes marked in units (U-100), the number of units to draw is:
These are the same formulas referenced in standard compounding pharmacy guides. No proprietary adjustments, no hidden rounding — just correct arithmetic applied consistently.
Editorial Standards
Every piece of content on Pep Formula is reviewed for mathematical accuracy before publication. Calculator logic is verified against published reconstitution protocols and checked with multiple independent inputs to confirm consistent output.
- ✓ All formulas traced to published pharmaceutical or clinical references
- ✓ Calculator outputs manually verified against known-correct values before launch
- ✓ Peptide-specific guides reviewed for accuracy against current research literature
- ✓ Errors reported by users are investigated and corrected promptly
