UK supplier comparison
Use the filters to pick a size and presentation (vial, pen or serum) and compare like for like, or view every size on a £ per mg basis. Delivery is shown separately because it varies by supplier and order size. Offers whose outbound link failed our last check stay listed but rank below working links.

Suppliers are being onboarded. This comparison will populate as listings go live. Everything below — the research profile, molecular facts and guides — is available now.
For in-vitro laboratory research only
HGH is listed here as a research material. It is not for human or veterinary consumption, and nothing on this page is medical advice or dosing guidance. PeptideCompare is paid by flat supplier fees — never by sales commission or referral — so a price ranks by its number, not by who pays. We do not sell, test or verify any product, and quality or CoA labels are suppliers’ own claims. Always check the final price, documentation and legality with the supplier yourself.
Research profile
About HGH in the lab
Somatropin is recombinant growth hormone identical to the main pituitary form. It is a licensed prescription medicine, and in research it is the reference ligand for GH-receptor and IGF-1 axis studies.
Proposed mechanism
Binds and dimerises GH receptors, activating JAK2–STAT5 signalling that drives IGF-1 production in the liver and direct metabolic effects in fat and muscle.
Structure note
Single-chain polypeptide with two disulfide bridges (191 amino acids).
Typical research themes
- JAK2–STAT5 signalling
- IGF-1 axis
- Recombinant proteins
Regulatory note
Prescription-only medicine in the UK and prohibited in sport (WADA).
This profile is a short, general summary of publicly discussed science. It is not exhaustive, not peer-reviewed by PeptideCompare, and is not medical advice. PeptideCompare provides no dosing, protocol or usage guidance — nothing here is for human or veterinary use.
