Unless my brain chemistry has changed since using the L-dopa, and I'm handling the same compound differently...which I suppose could be the case with what goes in and out of my brain on a daily basis.

Novel L-Dopa and dopamine prodrugs containing a 2-phenyl-imidazopyridine moiety.Denora N, Laquintana V, Lopedota A, Serra M, Dazzi L, Biggio G, Pal D, Mitra AK, Latrofa A, Trapani G, Liso G.
PURPOSE: The aim of this study was to gain insight into the feasibility of enhancing the delivery of L-Dopa and dopamine to the brain by linking these neurotransmitters and L-Dopa ethyl ester to 2-phenyl-3-carboxymethyl-imidazopyridine compounds giving rise to the so-called Dopimid compounds. MATERIALS AND METHODS: A number of Dopimid compounds were synthesized and both stability and binding studies to dopaminergic and benzodiazepine receptors were performed. To evaluate whether Dopimid compounds are P-gp substrates, [(3)H]ritonavir uptake experiments and bi-directional transport studies on confluent MDCKII-MDR1 monolayers were carried out. The brain penetration properties of Dopimid compounds were estimated by the Clark's computational model and evaluated by investigation of their transport across BBMECs monolayers. The dopamine levels following the intraperitoneal administration of the selected Dopimid compounds were measured in vivo by using brain microdialysis in rat. RESULTS: Tested compounds were adequately stable in solution buffered at pH 7.4 but undergo faster cleavage in dilute rat serum at 37 degrees C. Receptor binding studies showed that Dopimid compounds are essentially devoid of affinity for dopaminergic and benzodiazepine receptors. [(3)H]ritonavir uptake experiments indicated that selected Dopimid compounds, like L-Dopa and dopamine hydrochloride, are not substrates of P-gp and it was also confirmed by bi-directional transport experiments across MDCKII-MDR1 monolayers. By Clark's model a significant brain penetration was deduced for L-Dopa ethyl ester and dopamine derivatives. Transport studies involving BBMECs monolayers indicated that some of these compounds should be able to cross the BBB. Interestingly, the rank order of apparent permeability (P (app)) values observed in these assays parallels that calculated by the computational approach. Brain microdialysis experiments in rat showed that intraperitoneal acute administration of some Dopimid compounds induced a dose-dependent increase in cortical dopamine output. CONCLUSION: Based on these results, it may be concluded that some Dopimid compounds can be proposed as novel L-Dopa and dopamine prodrugs.

whatever the case, they really threw me for a a "WTF?" by saying that L-dopa does not cross the blood brain barrier.
certainly the derivative in the abstract there is too sophisticated and expensive for a supplement. and if you were gonna get that complex you are better served spending the resources and intellectual capital on more promising avenues then L-dopa

I never heard anyone say it was a precursor. Maybe it is, maybe it isn't, but I would imagine there could be other ways for it to raise dopamine levels. I've had suspicions about a few other products by USPLabs (ingredients with uncommon names), but I try to keep an open mind about it.
Here's what they had on their writeup about 1-C, in case you hadn't seen it.
A few years back a compound hit the bodybuilding scene with a lot of promise. It had great scientific research to back it up. That compound’s name was L-Dopa.
As you may know, L-Dopa could never duplicate it’s scientific performance in the real world. For one reason: L-Dopa could never cross the blood brain barrier…it would get absorbed in the blood stream and all hope of increased HGH production was lost!
In order for the brain to turn L-Dopa into dopamine…and therefore shoot HGH levels through the roof…this major obstacle had to be overcome…
At USP Labs we knew if we could come up with a bioavailable form of L-Dopa that had the ability to cross the blood/brain barrier it would help bodybuilders everywhere increase natural HGH release, natural Testosterone production, drive sex drive through the roof, build muscle, lose body fat and sleep like a rock.
Well, you will be glad when you hear we have succeeded! But, we totally skipped the L-Dopa part and discovered a brand new compound that’s closely related and is readily available for the body to use!
It’s called 1-C and it’s here to rock your world…
1-C, or 1-carboxy-2-amino-3-pyrobenzol(3,4 diol), is closely related to l-Dopa. In the past, many supplements touted L-Dopa as the next BIG THING in the supplement industry, but if failed miserably.
Synthetic L-dopa was created by the pharmaceutical industry to use in Parkisons disease to increase Dopamine levels that could increase muscle coordination. The research was good and bad mainly because Parkisons is not a well understood disease yet.
Again, in a study done in India, it was found that 1-C (a natural l-Dopa derivative) increased HGH levels through increasing dopamine levels naturally.

i am aware of that
but surely this would be a compound i would be familiar with, and others would be familiar with if it indeed is present in mucura puriens along with l-dopa
you are a nice guy so why don't you enquire with usp about this. i hope they don't play the "propietary information" game

i just dont understand how pat would say something like that when i know for sure most people seem to love powerfull and among all the people a small sample size must be proving that it works or does something beneficial.
i actually tested powerfull i think a while back got a bunch of pills in mail i dont honestly remember anything from it i think i continued to succed in my workouts and whatever but nothing that i remember being amazing. im not bashing powerfull i hope or look foward to trying it again soon.

•From Wikipedia, the free encyclopedia
Placebo effect is the term applied by medical science to the therapeutical and healing effects of inert medicines and/or ritualistic or faith healing manipulations. . When referring to medicines, placebo is a preparation which is pharmacologically inert but which may have a therapeutical effect based solely on the power of suggestion. It may be administered in any of the ways in which pharmaceutical products are administered. Regarding placebo procedures, psychic surgery is a clear example.
Sometimes known as non-specific effects or subject-expectancy effects, a so-called placebo effect occurs when a patient's symptoms are altered in some way (i.e., alleviated or exacerbated) by an otherwise inert treatment, due to the individual expecting or believing that it will work. Some people consider this to be a remarkable aspect of human physiology; others consider it to be an illusion arising from the way medical experiments are conducted.
The placebo effect occurs when a patient takes an inert substance (“a sugar pill”) in conjunction with the suggestion from an authority figure that the pill will aid in healing and the patient’s condition improves. This effect has been known for years.

You'll see on their write-up that it says this product has been shown to increase HGH and testosterone; however, this alone (on a scientific basis) does not necessarily mean that it will build muscle. Believe it or not, there were a lot of scientists back in the day who were convinced that Legit Anabolic Steroids wouldn't work. Obviously, research proved them wrong.
