heres a write up on nyca
NYC = norephedrine/caffeine/yohimbine
It was sold by syntrax as Adipokinetix
Heres the info I found on the stack and on "N" in general...
"YNCA (Yohimbine HCl 5mg, Norephedrine HCl, 25mg, Caffeine 100mg, Acetylsalicylic Acid 100mg)
Instead of ephedrine, YNCA uses norephedrine, specifically IR.2S
norephedrine. Ephedrine is indeed very thermogenic, but it
doesn't hold water compared to norephedrine. Studies show that
amphetamines are number one at raising metabolic rate and
norephedrine a close second. To make things interesting study
after study shows that the 1R,2S form is twice as potent as the 1S,2R form. Not only is norephedrine more thermogenic but it is also a better anorecitc, able to suppress appetite more thoroughly. Norephedrine triumphs over ephedrine on one more front because it passes the blood-brain barrier much less the ephedrine therefore stimulating certain parts of the brain much less. It has just enough to cause some pep but not so much as to cause the person to feel badly.
To potentiate the norephedrine caffeine and aspirin are added and voila we have the NCA stack. The Y stands for yohimbine, an alpha sub 2 adrenergic receptor blocker. To explain why this is added I must explain a little biochemistry. All of the ephedrine alkaloids do their work by stimulating nerve ending to produce
catecholamines like adrenaline, an adrenergic hormone. In turn,
adrenaline stimulates various adrenergic receptors of which there are the beta and alpha types. The receptors we want stimulated to increase the rate of fat loss are the beta sub 2 and and the beta sub 3. Fortunately, 1R,2S norephedrine does an excellent job of doing this. The receptor that we don't want stimulated is the alpha sub 2. It is this receptor that prevents fat mobilization
out of the cell. Thus, whenever this receptor gets stimulated,
no fat can get out of the cell and no subsequent burning of that fat can occur. Women have an especially large amount of alpha sub 2 receptors in their lower body and thus tend to have a very difficult time keeping fat off of this area.
As an alpha sub 2 adrenergic receptor antagonist, yohimbine is ideal at blocking the above described effect, allowing fat to be mobilized and burned. A final benefit of the yohimbine is the ability to increase the libido in both men and women!"
They should of stoped here,they had the best fat burner ever.Then they made lipokinetix and added sodium usiate (DNP) and a T2 thyroid hormone to nyc.
dropping 40lbs on that **** was easy,keeping your liver wasnt.
I remember when they launched it and they had a graph that showed how much eca,nyc ect raised your metabolism and eca was like 8-10% with there breathing machines hooked up to people and adipo wsa like 15-20% and lipo was over 40% lol
