Key facts
Somatropin is a 191-amino-acid recombinant growth hormone. It is also, of the whole catalogue, the product whose preparation puts people off most: the lyophilised form must be reconstituted carefully, degrades quickly and is dosed in international units rather than milligrams. The pre-filled pen removes that step entirely. 24 IU, or 8 mg, already in solution, dial-set.
Protocol and preparation
Warning Theoretical tool for chemical handling. Does not constitute medical advice.
- The pen carries a handwritten marking: the product initials and its strength. This is our marker on the pen body. Check that it matches your order.
- The needles are in the box, not on the pen. Four screw-on needles, a new one for each use.
- The liquid is clear and colourless, sometimes with a small air bubble. That is expected. Priming, before first use, clears the bubble.
- The parcel is plain. Nothing on the outside indicates the contents or the brand name.
What is not normal: cloudy or coloured liquid, visible particles, a cracked pen or a dial that will not turn. In those exact cases, write to us with a photo and we will take the pen back.

Mechanism of action
Somatropin reproduces the human growth hormone sequence and acts on its receptors, with much of its action mediated by IGF-1. It does not compare to the secretagogues in the catalogue, Ipamorelin, CJC-1295 or Tesamorelin, which stimulate endogenous production rather than supplying it directly. These are two distinct approaches, often confused.
