Synephrine hydrochloride
Molecular formula: C₉H₁₃NO₂
Molecular weight: 167.20

Appearance: white fine powder
Functions:
Synephrine is one of the adrenergic amines that stimulates the beta-3 receptors with minimal impact on the other receptor sites.
This functions to increase the metabolic rate without affecting heart rate or blood pressure.
Synephrine releases adrenaline and noradrenaline only in the beta-3 receptor sites (mostly adipose tissue and the liver). Stimulation of the beta-3 receptor sites elicits the breakdown of lipolysis (fat).
Synephrine is used to activate the adrenaline system without the stimulatory effect posed by ephedra-based products.
Shelf life: 2 years
