How cost-per-mg works

Cost per mg = vial price ÷ milligrams in the vial. Cost per dose = cost per mg × (dose in mg). Comparing per-mg normalises different vial sizes so you can see which vendor actually offers more peptide for your money — before you weigh in COA verification and trust.

Frequently asked questions

How do I work out the cost per mg of a peptide?

Divide the vial price by the milligrams of peptide in the vial. A €40 vial containing 10 mg costs €4.00 per mg. Comparing per mg lets you fairly compare vials of different sizes.

Why is cost per mg better than the sticker price?

A larger vial usually has a higher sticker price but a lower cost per mg, making it better value. Per-mg normalises the price so you compare like for like before factoring in COA verification and vendor trust.

Is the cheapest peptide always the best value?

No. A low price means little without verified purity. Always check the vendor's PeptScore and third-party COA status — paying slightly more per mg for verified material is often the better value.
