Norcoclaurine HCl (NorcolineTM) Effective as a stimulant or not?
I've been seeing it a bit more in Supplements, wondering it's effectiveness, if any or if great, at all...Is it actually Beneficial or just an addendum in the hope of replacing DMAA...maybe just a Filler?
Josh, Cyrus...Any articles or clearing up on this? I got some info myself, but I like the big boys educating us better before even throwing up whatever I have found !>SNS-Glycophase<Serious Nutrition Solutions Rep

It is an effective beta agonist. The downfall is an extremely short plasma halflife (~10 minutes). Finding a way to prolong it's HL would theoretically provide a pretty effective stimulant.

Is this at all similar to Higenamine. All I see in pubmed when searching for norcoclaurine is that it is involved in opioid synthesis, which would be anything but a stimulatory....unless it reduces norcoclaurine synthase activity?

Ah...this isn't the place to name products, but there are many supps that will use different nomenclatures to confuse people. Especially chemical names to make things look steroidal(not referring to this ingredient).Originally Posted by Celorza
Edit: check out the Hightower pharmacology blog for a good write up. That blog is great.

Might be fun to take before a good romping session...

Higenamine mediates cardiotonic, vascular relaxation and bronchodilator effects. The relaxation effects and the mechanism of action of higenamine on the rat corpus cavernosum (CC) were assessed to investigate the effect of higenamine on penile erection. Strips of CC and aorta were used in organ baths for isometric tension studies. Tension was measured with isometric force transducers, and muscle relaxation was expressed as the percent decrease in precontraction induced by phenylephrine (PE). The relaxation reactions were investigated in an endothelial-denuded group and groups pretreated with N(G)-nitro- methyl ester (NO synthesis inhibitor), propranolol (β-receptor blocker), indomethacin (COX inhibitor), glibenclamide (K(+)(ATP) channel inhibitor), 4-aminopyridine (membrane potential-dependent potassium channel inhibitor) and methylene blue (guanylyl cyclase inhibitor) for 30 min. Intracavernous pressure (ICP) was assessed in rats after the intravenous administration of higenamine, and changes in guanosine 3',5'-cyclic monophosphate and adenosine 3',5'-cyclic monophosphate (cAMP) concentrations were measured on the basis of the higenamine concentration. Also, the combined reaction of higenamine and the phosphodiesterase type-5 (PDE-5) inhibitors was assessed. Higenamine induced relaxation of the CC and the aortic strips precontracted with PE in a dose-dependent manner. The CC was significantly more relaxed than the aortic rings in response to the same higenamine concentration (P<0.05). The CC relaxation reaction was suppressed by the β-receptor blocker propranolol. The cAMP concentration increased gradually with increased higenamine concentration (P<0.05). The ICP also increased with increased higenamine concentration in vivo (P<0.05). In the group pretreated with 10(-7) M higenamine, the relaxation reaction of CC induced by the PDE-5 inhibitor increased significantly, compared with CC exposed to the PDE-5 inhibitor but not pretreated with higenamine (P<0.05). In conclusion, higenamine induced relaxation of the rat CC in a dose-dependent manner. The effect may be mediated through β-adrenoceptors. The results suggest that higenamine may be valuable as a new lead compound for treating erectile dysfunction.

A couple of points that should be made.
1. if higenamine has otheractive metabolites, then beneficial effects may continue to be seen aftercomplete elimination of the parent compound, depending upon thepharmacokinetics of those particular metabolites.
2. Having said that, this 10 minute plasma half-life figure is not being usedcorrectly in the context of the higenamine in the products. Half-life can andis often dependent upon the route of administration and sometimes the dose. Itis a critical error to take any pharmacokinetic variable's result from oneroute of administration and apply it to another. The only way to know what theplasma half-life after oral administration is to evaluate the plasma half-lifeafter oral administration. You can't take the half-life after intravenousadministration and apply that to oral administration. Usually, the half-lifeafter oral administration will be longer than that seen after intravenous. But,there are times where they will be the same or where the intravenous route willactually result in a longer half-life (more the exception).
3. If you use this stimulant, you'll understand half life is longer than 10 minutes.

1. This I agree with, and is the reason I believe I experience prolonged stimulation from higenamine, though I haven't really taken time to trace out its metabolites.
2. Eh, the HL may be longer orally, but then you have to account for other variables like AUC of plasma concentrations, pharmacodynamic issues (which wouldn't quite manifest as strongly via IV ), bioavailability (forseeably around 3% or less vs the obviously high IV bioavailability) etc...Ultimately, the difference in HL from administration methods in this instance will likely not account for the prolonged stim effect.
3. See #1

Personally my favorite stimulant...strong beta-agonist properties. The feel lasts 3-4 hours without a doubt. I feel it in the stimulation, the performance, and the breathing.

I've used Alpha T2,and currently .
All which contain Higenamine and all have given me great results in fat loss, energy and performance.
