Peptide reconstitution calculator (UK)
Work out the concentration of a reconstituted research peptide from the mass in the vial and the volume of bacteriostatic water added. This is dilution arithmetic for laboratory record-keeping: it tells you how concentrated a solution is, not how much of anything to use.
Research use only. This calculator performs dilution maths (concentration = mass divided by volume) for laboratory documentation. It is not medical, veterinary or dosing advice, recommends no amount, and The Peptide Watch sells nothing and links to no seller. Reconstitution and reagent handling should follow your own laboratory's protocols.
How the maths works
Concentration is the peptide mass divided by the solvent volume. 10 mg of peptide in 2 ml of water gives 5 mg/ml, i.e. 5,000 mcg/ml. On a U-100 insulin syringe one unit is 0.01 ml, so at 5 mg/ml one unit holds 50 mcg. To measure a chosen amount, divide it by the concentration to get the volume, then multiply by 100 for U-100 units.
Before trusting any vial, confirm the seller's testing: how to verify a Janoshik COA or the independently-tested list.
