Synephrine Hcl in Fatburner & Weightloss Products
Synephrine Hcl (Citrus Aurantium) is an alkaloid derived from bitter orange. Because Synephrine HCL is chemically and pharmacologically related to ephedrine as a phenylethylamine derivative, the use of Synephrine HCL in fat burners is very conclusive.

Synephrine Hcl vs Ephedrine HCL:
Chemically, Synephrine HCL has a strong similarity to ephedrine (ephedrine HCL). Ephedrine is one of the three ingredients in the so-called “ECA” stack (ephedrine, caffeine, aspirin). Both substances (synephrine HCL & ephedrine HCL) are considered to be stimulators of beta receptors. Beta receptors are responsible for fat burning. However, with the difference that Synephrine HCL is considered less worrying about possible side effects. Synephrine HCL , in contrast to ephedrine, activates only specific receptors (the “beta-3” type). So Synephrine HCL is a beta-agonist.
