HCG
REC PPT-HCG // REV 2026-10-04 // assessment changes are logged, never silent
Approved gonadotropin. The weight-loss ‘HCG diet’ is separately discredited.
What it is
Human chorionic gonadotropin, a hormone approved for fertility and specific endocrine indications.
What it does
Mimics luteinising hormone, stimulating gonadal steroid production; used in fertility protocols and to maintain testicular function during testosterone therapy.
Does it work?
Endocrine uses are legitimate and physician-supervised. The ‘HCG diet’ for weight loss is a distinct claim that regulators and trials have repeatedly rejected — do not conflate them.
Claims vs data
Each marketing claim, tagged by what the evidence actually supports.
| Supports testicular function during TRT | supported |
| Causes weight loss (HCG diet) | overreach |

The evidence, counted
Live counts from Europe PMC and ClinicalTrials.gov.
47,738 publications indexed, including 1104 randomised controlled trials. 569 interventional studies registered. This is a well-tested compound.

Common questions
Why is HCG used alongside testosterone therapy?
It mimics LH, maintaining testicular stimulation that exogenous testosterone suppresses — an established, physician-supervised endocrine use.
Is the HCG diet real?
It is really marketed and really discredited. Controlled trials repeatedly found no weight-loss benefit over placebo, and regulators have acted against the claim for decades.
Is HCG available without prescription?
Not legitimately. It is a prescription medicine in Saudi Arabia and most jurisdictions.
