Overview
Safety information for HCG (human chorionic gonadotropin) depends on how extensively it has been studied in humans, how it is manufactured, and in what context it is used. Many catalog peptides have more preclinical than clinical safety data.
Common safety themes
For peptides in general, discussions of side effects often include:
- Local reactions at injection sites.
- Systemic symptoms such as headache, fatigue, or gastrointestinal upset.
- Uncertainties related to long-term exposure, interactions, and product quality.
Context and caveats
Absence of large, well-controlled human studies means that true risk profiles for many peptides remain incompletely defined. Regulatory status, manufacturing controls, and supervision by qualified clinicians are central to interpreting any safety conversation about HCG (human chorionic gonadotropin).
Sport & Anti-Doping Warning
Human chorionic gonadotropin (hCG) has been misused by male athletes as part of steroid cycles to stimulate endogenous testosterone and is specifically prohibited in male competitors.

In anti-doping rules, hCG is banned in males and often treated as a marker of attempted steroid cycle manipulation rather than a benign fertility drug.
