Storing your pens

Pens hold the peptide in solution, so they need a little more care than freeze-dried vials.

Pre-filled pen FAQ

Do pre-filled pens need reconstituting?

No. The peptide is already dissolved at a fixed concentration, so there is no mixing step in the lab.

What is the difference between Glow and Klow?

Klow contains everything in Glow (GHK-Cu 50mg, BPC-157 10mg, TB-500 10mg) plus 10mg of KPV. See Glow vs Klow explained.

Should I choose a pen or a vial?

Pens save preparation time and give a consistent concentration. Freeze-dried vials keep longer and let the lab set its own concentration. See vials vs pens.

How do I check the purity of my pen?

Every batch is third-party tested, with results shown on each product page. Our guide on reading a CoA explains what to look for.

How quickly will my order arrive?

Orders placed before 3pm are dispatched the same working day, in plain, discreet packaging. Express delivery takes 1–2 working days and standard delivery 3–5, with free UK delivery on orders over £60.

All pre-filled pens are supplied strictly for laboratory and scientific research use. Not for human or animal use.
