KEY TAKEAWAY

A change in a biomarker and a health benefit are different study outcomes.

Identify the endpoint

A publication may describe a change in a laboratory measurement without assessing wellbeing or functional recovery. Check what the authors actually measured.

Don't overlook the risks

The FDA highlights safety concerns for some substances associated with growth hormone release. The risk depends on the particular substance and how it is used.

Check the sporting rules

A substance's status in sport is determined by the current rules. Do not rely on a seller's claim that it is permitted: consult the official list and a qualified professional.
