# What is the cheapest research peptide per mg in the UK? League table, October 2026

Ranked by price per mg at its best-value vial size, the cheapest compound at the 16 October 2026 UK price check was NAD+ at £0.050/mg. The dearest was Follistatin 344 at £49.97/mg. Per-mg price mainly tracks how hard a compound is to make, not how widely it is sold.

## Why is per-mg price so different between compounds?

-   Synthesis length: a 3-residue peptide costs far less to make per mg than a 39-residue lipidated one.
-   Production route: recombinant proteins (IGF-1 LR3, follistatin) cost the most per mg.
-   Non-peptides: NAD+ and GHK-Cu are sold in 50–1000 mg amounts at low per-mg prices.
-   Vial size: larger vials are usually cheaper per mg.

## Is per-mg price a fair way to compare compounds?

Only for budgeting. Across different compounds it is not a quality or value measure, because the molar amount per mg and the experimental amount needed differ. Within one compound it is the right measure.

## How was the price check done?

Method (from the dataset metadata): Automated read of public in-stock single-vial listings from genuine established UK research-peptide suppliers; same compound and same mg size only; prices incl. VAT as listed, excluding postage. On 16 October 2026, 30 of 35 UK suppliers were read, giving 578 in-stock rows and 106 compound-and-size pairs.

Medians and ranges cover other sellers only. Sable's own price is not included in them. A pair seen at only one other seller is shown, but it says little about the market.

## Frequently asked questions

### What is the cheapest research peptide per mg?

### Why is IGF-1 LR3 expensive per mg?

It is an 83-residue recombinant protein, which costs far more to produce than a short synthetic peptide.

### Is price per mg comparable across compounds?

Only for budgeting. It is meaningful within one compound across sizes and sellers.
