Reading a vial label

A small glass vial does not hold much information, so the label carries a lot of weight. Reading it properly when a parcel arrives takes a minute and saves a great deal of confusion later.

What a kit is

A Pep Pantry kit is ten vials of one compound at one strength. Every vial in a kit holds the same amount, and every price on the site is for a full kit. If your order includes several kits, each is ten identical vials of its own product.

What the label tells you

  • The compound name, written in full. Many names look alike, so match it letter for letter to your order.
  • The strength, such as 5mg or 10mg. This is the amount of the compound in each vial, in milligrams.
  • Any further markings the supplier has added. Note them down with your records.

Check it against your order

When a parcel arrives, compare the name and the strength on the vials with your order confirmation, and count the vials in each kit. If anything does not match, write to support@pep-pantry.is with your order number and a clear photo, and we will look into it.

Keep the label readable

Condensation and spills can smudge a label, so keep vials dry on the outside, especially when they come out of cold storage. If a label is fading, copy its details onto a fresh one before the original is lost.

Add to the label after reconstitution

Once a vial has been dissolved, add the date, the diluent and the final concentration to the label. A vial that says only its compound and original strength cannot tell you what is actually inside it any more. Our post on reconstitution shows where that fits in the routine.

If something looks wrong

A cracked glass, a loose cap or a leaking vial should not be used. Photograph it, keep the packaging, and write to support@pep-pantry.is with your order number so we can sort it out.
