Units explained

  • mg and mcg are both weight: 1 mg = 1,000 mcg. Read the unit as carefully as the number, because the wrong one is a thousand times out.
  • IU measures activity, not weight. There is no fixed number of mg in an IU, so an IU product is worked in IU from start to finish and never converted to mg.
  • mL is the liquid: the water that goes into the vial and the volume that comes out of it.
  • Syringe units are the marks on an insulin syringe. This calculator works in U-100 syringes, the standard kind: every unit mark is 0.01 mL, whatever the size. A 0.3 mL syringe holds 30 units, a 0.5 mL holds 50 and a 1 mL holds 100, and 10 units is the same amount on all three. Check that your syringe's barrel says U-100 before drawing; if it doesn't, these numbers don't apply.

Which water

BAC (bacteriostatic) water is the standard for mixing our vials. AA water works better for some peptides — ask us if you'd like to know which. If a product page names a particular water, follow the product page.

BAC water: BAC WATER 10mL, BAC WATER 30mL

AA water: AA WATER 10mL

Handling and storage

General handling and storage guidance for research use. If a product page has its own notes, follow those first.

Before mixing (dry powder vials)

  • Keep sealed vials in the fridge (2-8°C). For storage longer than a few months, the freezer (-20°C) is better. A few days at room temperature in the post is fine for a sealed dry vial.
  • Keep them in their box, away from heat, sunlight and moisture.
  • Don't puncture a vial until you're ready to mix it.

Mixing

  • Wash your hands and work on a clean, dry surface.
  • Wipe the rubber tops of both vials with a fresh alcohol swab and let them dry.
  • Use a new, sterile needle and syringe every time. Never reuse or share them.
  • Use BAC water, or AA water where it suits better (see "Which water" above).
  • Let the water run slowly down the inside wall of the vial, not straight onto the powder.
  • Swirl gently or roll the vial between your fingers. Don't shake it: shaking can damage the peptide.
  • If some powder hasn't dissolved, put the vial back in the fridge for a while, then swirl again.
  • Write the date and the concentration (from the calculator) on the vial.

After mixing

  • Back in the fridge (2-8°C) straight away, away from light.
  • Don't freeze a mixed vial. Freezing and thawing damages peptides.
  • Throw it out if it turns cloudy, has particles, changes colour, or the rubber top is damaged. If in doubt, throw it out.

Oils

  • Store at room temperature, away from heat and light. Don't refrigerate: cold can make the oil crystallise.
  • If you see crystals, warm the vial gently (for example in warm water) and swirl until it's completely clear. If it won't clear, don't use it.
  • Same hygiene: swab the top, and use a new sterile needle each time.

Orals

  • Keep the bottle tightly closed, somewhere cool and dry, out of direct sunlight.

Calculated figures only. Check your own measurements, and always confirm your syringe type before drawing.
