Product identity matters
When researching branded somatropin, compare the manufacturer, presentation, labeling, prescription pathway and handling requirements rather than treating every product advertised as “HGH” as interchangeable.
Prescription status
Human growth hormone is prescription medication in the United States. A legitimate treatment pathway includes clinical evaluation and dispensing through appropriate channels.
Storage and handling
Follow the current manufacturer labeling and pharmacist instructions for the exact presentation you receive. Storage requirements can differ before and after first use.
