This is basically a structural modification to synephrine that seems to be more potent at burning fat. It is an ingredient that is short on information, but in theory looks interesting. I would say that this is probably pretty good, just lacks any clinical studies on what it does. Still, from the structure of the molecule we can predict it to be somewhere between synephrine and ephedrine in potency. It takes the basic Synephrine molecule and replaces the top hydroxyl with a methyl group, making it a hybrid synephrine/ephedrine molecule. Very interesting indeed, but certainly not 100% tested. I’ve taken this, but it was always mixed with caffeine and other stimulants, so it is hard to tell exactly what this would do on its own. It is extracted from acacia seeds, making it legal to sell as a dietary supplement. MethylSynephrine is certainly one to watch!
