Reconstitution calculator
Enter what is in the vial, how much water you are adding, and the dose you intend to draw. This returns the concentration and the volume that dose corresponds to.

Handling and storage
Safety content, published deliberatelyReconstitution technique and storage are published here because they reduce harm for someone who has already decided to proceed, and because none of it involves us specifying what anyone should take.
- Bacteriostatic water contains a preservative and is the standard diluent for multi-use vials; sterile water has no preservative and is single-use.
- Add the diluent slowly against the inside wall of the vial rather than directly onto the powder, and swirl rather than shake. Peptides are proteins and mechanical agitation degrades them.
- Swab the stopper with alcohol before each entry, and use a new sterile needle each time.
- Lyophilised powder is generally stored cold and dark; once reconstituted, product is refrigerated and has a far shorter useful life. Follow the storage information supplied with the material you have.
- A cloudy, discoloured, or particulate solution is not usable. Do not filter it and proceed.
Nothing on this page verifies what is in a vial. We do not test products, and reviews do not reliably detect underdosing, substitution, or degradation — “no effect” is indistinguishable from a compound that simply does not work. Why that limit exists
