Glossary
The technical terms used on this site, in plain words.
- Aliquot
- A smaller portion taken from a larger amount of liquid, usually kept in its own container.
- Bacteriostatic water
- Sterile water with a small amount of benzyl alcohol (0.9%), which slows bacterial growth. Commonly used for vials that are opened more than once.
- Cartridge
- A sealed tube of liquid that fits inside a pen.
- Certificate of analysis (CoA)
- A laboratory document that reports test results for one batch, such as purity.
- Concentration (strength)
- How much peptide is in each millilitre of liquid. It is the mass divided by the volume, written as mg/mL.
- Data sheet
- The maker's or supplier's document giving storage and handling details for one specific peptide.
- Diluent
- The liquid added to a powder to dissolve it. For peptides this is usually bacteriostatic water.
- Draw volume
- The volume of liquid pulled into the syringe. It is the target amount divided by the strength.
- Lyophilised
- Freeze-dried. The water is removed under vacuum, leaving a dry powder.
- mcg (microgram)
- One thousandth of a milligram. 1,000 mcg equal 1 mg.
- mg (milligram)
- One thousandth of a gram.
- Peptide
- A short chain of amino acids.
- Reconstitution
- Adding liquid to a dry powder so it dissolves. This site calls it mixing.
- A rigid container for used needles.
- Stopper
- The rubber seal on the top of a vial.
- Target amount
- The amount of peptide a calculation aims for. The calculator turns it into a draw volume.
- U-100
- A syringe standard where 100 units equal 1 mL, so 1 unit is 0.01 mL.
- Unit
- On a U-100 syringe, 0.01 mL of liquid. A unit measures volume, not peptide.
- Vial
- The small glass bottle the peptide comes in.
