Someone asked me to explain why I have added Yohimbe to my ECA stack. Here goes... Adrenaline and Noradrenaline both bind to a receptor called the Adrenoreptor. The Adrenoreptor is composed of two types of receptors: beta-receptors and The beta receptor is also subdivided into beta-1, beta-2 and beta-3 receptors. The alpha receptor is subdivided into alpha-1 and alpha-2 receptors. Ephedrine or Clenbuterol are both known as beta-2 agonists meaning they stimulate The stimulation of the beta receptors accelerates certain processes in the body like: Ephedrine also stimulates the alpha receptor. It is causing a negative effect on fat loss Yohimbine (found in the herb yohimbe) is an alpha-2 antagonist. This means when You can use Yohimbe by itself and it will definitely help a lot. Since it stops the alpha Stacked with the ECA stack Yohimbine is super effective. Unfortunately I can't recommend it. They both increase heart rate and blood I have done this stack before and noticed irregular heart beats and chest pain so I Upon taking almost an hour to research this question and to make this post. I ECA + Y + 1000mg of Test per week will give me lots of problems. Ephedrine and Yohimbe have short half lives so you could take some ephedrine and I will either alternate my stack between every dose or take ECA one day and YCA Effective daily dose of yohimbine is 0.2mg per kilogram of bodyweight. Any questions? ------------------     | ||

Good post. But you made one mistake. Ephedrine is NOT a beta-2 agonist, it is an unselective beta adrenoreceptor agonist. According to research done in medline, ephedrine stimulated the following receptors after an oral dose: Beta 1+3: 57% Beta 2: 43% This was accomplished by using selective beta-2 blockers with ephedrine administration. Also, beta2 receptors are involved in protein synthesis. Decaman, I believe was one of the first to try out ephedrine+Clen simultaneously. I posted a post explaining why ephedrine+Clen was a viable option about 5 months ago, don't know were it went....(must be that elusive glitch.....LOL) This is possible if you lower your clen dosage slightly to saturate the beta-2 receptors after administering ephedrine, which will stimulate the beta-3 receptors, which in my opinion are the most important for fat loss since they don't downregulate ever. In as far as yohimbine is concerned, the half-life of oral yohimbine is 36 minutes or 3/5 of an hour. Godspeed | ||

Forgot something.... Oral yohimbine(extract) is SHIT. It does nothing. Only yohimbine HCL is effective when taken orally, even better topically w/DMSO (but thats another story). As far as ephedrine is concerned, it has a half-life of 4 hours, Clen has a half-life of 48 hours. Did yohimbine(extract) at 40mg per dose(that was 0.34mg/Kg at 90Kg), and got ZERO results. It does marginally work as a libido booster though.. Godspeed | ||

Fonz: I agree about ephedrine being an unselective beta adrenoreceptor agonist. My bad! Thanks for the correct half lives I was just posting of the top of my head. Another person asked me why products that have nor-ephedrine and yohimbine are legal and don't cause as much trouble as ephedrine and yohimbine. My assumption is that maybe nor-ephedrine acts more on beta-2 and beta-3 and less on beta-1 receptors. For the others, beta-1 recpetors are primarily found in the heart. ------------------ | ||

I remember Macro saying that yohimbe bark extract had all the garbage that caused the side effects. If you where to take pure yohimbine you wouldn't get any sides. If you can't tolerate yohimbe alone please don't stack it with ephedrine. I have thought how I will use ECA and Yohimbe together to avoid too much increase in Heart Rate or Blood Pressure. I will take four stacks per day. Assuming I wake up at 9am and go to bed at 1am. 9am: 25mg of Ephedrine, 200mg of Caffeine, 1/2 aspirin 1pm: 5mg of Yohimbine, 100mg of Caffeine 5pm: 25mg of Ephedrine, 200mg of Caffeine, 1/2 aspirin 9pm: 5mg of Yohimbine, 100mg of Caffeine This gives me a total of 50mg of E, 600mg of C, 10mg of Y and 1 aspirin per day. Seems resonable. What do you guys think? Should I do one day ECA and the other day YCA instead? By the way someone emailed me. Ephedrine half-life is 4hours and Yohimbine is 36min. ------------------ | ||

DREXX, yohimbine HCL is not OTC. It is only available from pharmaceutical houses. Also, looked over your dosing schedule, one thing: Dosing yohimbine throughout the day will not work very well. You must take it all at once. Preferably in the morning before cardio. Even though yohimbine is rapidly excreted its metabolites which also have good A2-blocking abilities have a half-life of 7 hours. Hope this helps... Godspeed | ||

good post drexx and fonz but why must the yohimbine all be taken in the morning? wouldn't it work to spread it out over the day? | ||

Fonz: I have heard that all the yohimbine should be in the morning before but never understood why. Besides the fact that the presence of insulin will make yohimbine inneffective. So it wouldn't be good between meals? ------------------ | ||

Ok, Ok DREXX...I'm here...LOL Just a tad pissed off from all the stupendous critiques I'm getting <sarcasm>. Anyways, to answer your question, it all has to be taken in the morning in order to FULLY ANTAGONIZE the A2 adrenoreceptor. That is why you should do cardio right after for maximal A2 fat loss(located on the stomach for guys). If you took it during the day(spaced evenly) you would only partially antagonize the aforementioned receptor, therefore not accomplishing any fat loss. Also, in the morning insulin levels are lowest and yohimbine's lipolitic ability is dependent on low insulin levels. After they reach a certain point, lipolysis will halt, even with the addition of Yohimbine. This certain point is not all that high BTW. Also, just as a tidbit: Yohimbine+Carbs at the same=greater insulin response than carbs alone. Hope that clears it up. Godspeed | ||

Thanks Fonz! I guess I will rethink my dosing plan. Actually I may go for Adipo from Syntrax since it contains Nor-E, Yohimbine and Caf all in one pill I would also add in some extra yohimbine in the morning before cardio. ------------------ |
