Is this spam? synephrine is a citrus extract found in many thermogenics these days, and not just this product. Also synephrine can not possibly have the same fat burning qualities of ephedrine because ephedrine directly and indirectly stimulates beta receptors, like the beta-3 receptor, which is key in fatloss, and synephrine stimulates alpha receptors with minimal beta receptor stimulation. Ephedrine also significantly increases resting metabolic rate and while synephrine barely does. Smells like spam to me...![]()
