Precise math for peptide research.

Solution math

Reconstitution Calculator

Vial, water, target, and draw — fill any three and it solves the fourth. Returns concentration and exact U-100 units.

Solution math

Blend Reconstitution

For a vial holding two peptides (like CJC-1295 + Ipamorelin) — see how much of each lands in a single draw.

Reference

Reconstitution Chart

A quick lookup — enter the mg per vial and see concentration and syringe units across common water volumes and doses.

Solution math

Purity-Adjusted Concentration

Your label says one mass; the COA purity says another. See the effective peptide content and true concentration.

Physicochemical

Peptide Property Calculator

Paste an amino-acid sequence for molecular weight, isoelectric point, net charge, and extinction coefficient.

Reference

Amino Acid Reference

The 20 standard amino acids — one- and three-letter codes, residue mass, charge class, and hydrophobicity.

Physicochemical

A280 Concentration

Convert UV absorbance at 280 nm into solution concentration using the extinction coefficient.

Solution math

Dilution Calculator

C₁V₁ = C₂V₂ — fill any three of stock concentration, stock volume, final concentration, final volume.

Reference

Unit Converters

mg ↔ mcg ↔ ng, mL ↔ units, mass ↔ moles, °C ↔ °F, and mm ↔ inches — type any field.

Reference

Cost per mg

Compare value across vial strengths and prices on a true cost-per-milligram basis.

Verification

COA Reader

A guided walkthrough of a Certificate of Analysis — identity, purity, net content, batch, and lab accreditation, with a trust checklist.

Reference

Storage & Stability Reference

Lyophilized vs reconstituted handling — temperature, light, freeze-thaw, and how long a mixed vial lasts.
