Known does not mean proven for everything.
The strongest claim on the page should never be stronger than the strongest source behind it.
- A regulated US product has a specific, evidence-backed indication in adults with HIV-associated lipodystrophy.
- The licensed evidence cannot be automatically transferred to general fat loss, bodybuilding or longevity.
- The FDA label says long-term cardiovascular safety has not been established.
- Risk–benefit outside the authorised population and indication.
- Long-term outcomes when used for physique or anti-ageing goals.
- Identity, sterility and potency of unregulated online vials.
- The FDA label covers elevated IGF-1, glucose intolerance or diabetes, fluid retention and hypersensitivity.
- Active malignancy and pregnancy are among the important label restrictions.
- This page gives no dosing, mixing or injection instructions.
