What Does 10mg Mean on a Vial? Picking the Right Size

The number on the label is how much peptide powder is in the whole vial. A 10mg vial holds 10 milligrams in total. A 5mg vial holds half that, and a 20mg vial holds twice as much.

Does the size change the peptide?

No. A 5mg Tirz and a 20mg Tirz are the same compound. The only difference is how much of it you get.

Blends add up

On a blend, the number is everything combined. KLOW 80mg is the sum of four peptides, not 80mg of each.

Picking a size

Trying a compound for the first time? A smaller vial like Tirz 5mg or Reta 5mg lets you look before you commit.
Know you need more? Larger sizes like Tirz 30mg or Reta 30mg usually cost less per milligram. Each product page shows the price per mg.
Running a longer project? Buy as many vials as you like. Every size ships free in the USA.
