Somatropin units explained: what 144 IU means, and why it is also 48 mg

Published 9 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Somatropin is recombinant human growth hormone, a 191-amino-acid polypeptide identical in sequence to the pituitary hormone. It is quantified both by mass and by international units because the IU is a historical potency measure that predates reliable mass assay. At the conversion this catalogue uses, 3 IU corresponds to 1 mg — so a 144 IU pack is 48 mg, supplied as two 72 IU vials.

Why two units exist at all

The international unit was defined when growth hormone came from pituitary extract and could only be compared by biological activity against a reference preparation. Potency was what could be measured; mass was not reliably known.

Recombinant production changed that. A protein expressed from a known sequence can be quantified by mass directly, and modern material is characterised that way. The IU survived because decades of literature, labelling and reference standards are written in it, so both units are carried side by side.

The practical consequence is that any figure in IU only means something alongside its conversion. This catalogue states both: 144 IU, 48 mg.

Why somatropin turns up as a reference material

Somatropin is among the most thoroughly characterised recombinant proteins in the literature. Its sequence, structure, folding behaviour and degradation pathways are documented in detail, and reference preparations exist against which other material can be compared.

That is why it appears in analytical work as often as in growth-axis research — as a known quantity for validating an assay, a column or a method. Research applications in the growth-hormone axis itself centre on IGF-1 induction, receptor signalling, and body-composition and metabolic models.

Handling, and what arrives

Somatropin is a protein, and proteins are less forgiving than short peptides. Lyophilised material is kept refrigerated and protected from light; once reconstituted it is sensitive to repeated warming and to freeze-thaw cycling, and to agitation, which can drive aggregation.

The pack holds two 72 IU vials under one batch record with a single certificate of analysis. Bacteriostatic water is not included. Supplied for laboratory research use only — REVIVE LAB UAE provides no dosing or administration guidance of any kind.
