UK Peptide Pen Strength Index

The same blend name can hold very different amounts of material. This index lists how many mg each UK seller puts in a pre-filled pen or cartridge, and what one mg costs, so pens can be compared on content rather than on shelf price.

How the index is built

  • Every figure comes from the seller's own product page on the date shown above. Each row links to its source.
  • Only ready-to-use formats are compared: pre-filled pens and pre-mixed cartridges, one unit, the standard single-unit price.
  • Prices are in GBP as displayed. Euro and dollar prices are converted at 1 EUR = £0.8594 and 1 USD = £0.74.
  • Price per mg is the unit price divided by the total mg stated for that pen or cartridge. It says nothing about purity: for that, compare the batch certificates.
  • Listings whose mg or price could not be confirmed on the seller's page are left out. Sellers change prices, so re-check before buying.
  • Celyfe publishes this index and sells pens in it; Celyfe rows are highlighted.
