Summary
DMHA is a synthetic sympathomimetic stimulant originally developed as a nasal decongestant in the 1940s-1950s. The FDA considers DMHA an unsafe food additive and has issued warning letters to supplement manufacturers. It is banned by WADA for athletic competition and is illegal in several countries including Australia, Canada, and parts of the EU. Users with cardiovascular conditions, hypertension, or glaucoma should avoid use. Start with lower doses due to individual variability in response and potential for overstimulation.
