Growth hormone is the most expensive compound in this catalogue and the most counterfeited. Those two facts are related. The realistic effects are slower and subtler than the marketing suggests, the cost is genuinely high, and a cheap HGH listing is close to a guarantee that something is wrong.
What it actually does
Somatropin is recombinant human growth hormone — a 191-amino-acid protein, not a peptide fragment. In adults with genuine deficiency, replacement improves body composition, bone density and quality of life. That is a clinical use with clear evidence behind it.
In people without deficiency, effects are real but modest and slow:
- Fat loss, particularly visceral — the best-supported effect
- Improved recovery and connective-tissue repair — widely reported, less rigorously quantified
- Skin and sleep quality — commonly reported
- Muscle gain — the weakest claim. HGH increases lean mass substantially through water and connective tissue, but its effect on contractile muscle in healthy adults is far smaller than an equivalent spend on anabolics
Timescale is months, not weeks. Anyone promising rapid visible change is describing something else.
Why it costs what it does
Somatropin requires recombinant protein production in engineered cell lines — a fundamentally different and more expensive process than the chemical synthesis used for peptides like CJC-1295 or ipamorelin.
Across our growth hormone category, presentations run from around £225 to nearly £1,000 depending on IU count. That band is what legitimate production costs look like.
A cheap HGH listing is the clearest fraud signal in this catalogue. The three usual explanations: it is underdosed, it is a cheaper growth-hormone-releasing peptide relabelled, or it is bacteriostatic water. All three are common.
The cheaper alternative, honestly described
Growth-hormone secretagogues — ipamorelin, CJC-1295, GHRP-2 and GHRP-6 — stimulate your own pituitary to release GH rather than supplying it directly. They cost a fraction as much.
The honest comparison: they produce a pulsatile release constrained by your own physiology, which is both their safety advantage and their ceiling. They cannot reach the levels exogenous somatropin does. For recovery and sleep they are a reasonable option; as a substitute for HGH they are not equivalent, and pages implying otherwise are overselling.
The risks that matter
- Insulin resistance. GH raises blood glucose and opposes insulin. This is the most important long-term concern and it is invisible without testing — fasting glucose and HbA1c.
- Carpal tunnel and fluid retention. Common, dose-dependent, usually resolves on reduction.
- Acromegalic changes. Growth of extremities and facial bone at sustained high doses over years. Not reversible.
Legal position
Somatropin is a prescription-only medicine in the UK, not a controlled drug — a different offence structure from anabolic steroids. Supplying it without authorisation is an offence under the Human Medicines Regulations 2012. See are peptides legal in the UK?
Frequently asked questions
Will HGH build muscle?
Far less than the marketing implies. Much of the lean-mass increase is water and connective tissue. For contractile muscle, the same money spent elsewhere does more.
How do I tell if HGH is real?
Price is the first filter — genuine somatropin is expensive everywhere. Beyond that, batch verification and lab analysis. See how to check a brand is genuine.
Are peptides a substitute for HGH?
Not equivalent. Secretagogues work within your own pituitary’s limits, which caps what they can achieve. They are cheaper and gentler, not the same thing.
