fonz im going to keep this impersonal and precise because your argument is, well, what can i say....true to form

youre nothing if not predictable.
so, if you want to argue, first id like to see you justify your comments. im a pharmacist, a huge upside of which is that people take me at my word. your word on the other hand is worth...little. so try to back it up please.
ill even let you in on my game plan (arent i a nice bloke?). its really quite simple. im going to get you talking and let you expose your own ignorance. and let me say from the outset, your comments in this thread have already condemned you. but anyway, here you go:
thanks for pointing that out. i dont know what the point of this statement is. are you coaching your audience to agree with everything you say? trying to sound intelligent by repeating the obvious? but hey, thanks man. i didnt know that. clenbuterol burns fat? revolutionary.
please back up your assertation of the specificity of clenbuterol on the beta 2 adrenergic receptor. in particular could you please explain why an agent with beta 2 specificity has side effects attributable to agonism of the other beta adrenoceptors (those being of course, 1, 3 and 4) for instance i would like you to talk about muscle tremor.
ill even give you a tip. this is the most important question in this reply. please answer it well.
please explain the biochemical basis for this effect. (this is the 2nd most important question in this reply. do a good job on it, mate. good luck hehe

Clenbuterol: a substitute for anabolic steroids?
Prather ID, Brown DE, North P, Wilson JR.
Department of Family Medicine, University of North Texas Health Science Center at Forth Worth 76107; USA.
Clenbuterol is a recently popular drug used by athletes in many sports for its purported anabolic effects and reduction of subcutaneous fat. It is a beta-2 (beta 2) agonist prescribed overseas as a bronchodilator, but not approved for use in this country.

Muscle tremor happen due to TOO MUCH adrenaline floating around your system. Think of adrenalne as bio-chemical energy. The muscles can only accept a certain amount. Now, Clenbuterol mimics adrenaline by activating the Beta-2 receptor(It is used by asthmatics and has been used for decades), so if you where senitive to too high adrenaline levels, your muscle-neural connections would overload with too much bio-chemical energy, and your muscle would twitch.
ill
ok theres a couple of things id like you to explain. why does ephedrines non specificity make it any less powerful for fat burning?
Question3:
Ephedrine unlike Clenbuterol which exclusively activates the Beta-2 Receptor and raises your body temperature, ephedrine is an unselective agonist which targets the Beta-1's,2's amd 3's. The % is 43% B2 and 37% B3. If you haven't read the literature regardung that I suggest you find it yourself. Therefore, there is quite a difference in the agomism of the Beta-2 receptor from ephedrine in regards to that of Clenbuterol: 100/43 = 232% greater Well, that's quite a big difference in terms of raising the body temperature.
But epehdrine also actuvates the Beta-3, which itn turns activates BAT, which in turn dissipates fat for energy. However, most adults have little BAT in their bodies so that aspect of Ephedrine's beta-3 agonist peoperties isn't very strong. This Beta-3 property will never downregulate however, as the Beta-3 receptors never do, which make Ephedrine a better drug than clenbuterol in the long-term.
also, could you also explain why there is no downregulation of the beta 3 receptor, especially given that 1) ephedrine loses efficacy over prolonged exposure (kind of indicates downregulation, wouldnt you say?) and 2) that downregulation of receptors is a body wide phenomenon that no receptors are resistant to?
Question4)
The reason why ephedrine loses efficacy after prolonged exposure is that the beta-2 adrenorecptors that ephedrine activates at the outside of the cell, translocate inwards. Therfore, since they are INSIDE the cell and not outside Ephedrine cannot activate them, and nothing happens.
The beta-3 receptor activates BAT tissue. BAT tissue is brown fat with massive amounts of mitochondria, that just burns fat for fuel through thermogenisis. When young, you have a considerable amount of Beta-3 adrenoreceptors, but over time we begin to lose them. However, once we reach maturity they stay fixed. No matter how much you stimulate them they will, not downregulate, because your BAT tissue can just keep on dissipating energy via thermogenesis. The Beta-2's however can't. The more you keep stimulating tyhem, the more adrenaline floods your system and the more dangerous it becomes for you. So, the bodies feed-back loop for this is to translocate the Beta-2 receptors to the inside of the cell to avoid further stimulation from the outside of the cell and allow the dangerous levels of adrenaline that have already been built up to subside to normal levels.
hm well i think you need to go to pharmacy school in the first place

if for no other reason but to learn that there isnt actually an adrenergic system. i think youre talking about the sympathetic nervous system. but anyway, i dont want to distract you. just reply, IN DETAIL, to the questions i posed. thanks.
edit: oh by the way, some of the things i have asked you to look up (not saying which hehe) are just for the purpose of wasting your time while you try to hunt down info to throw at me. have fun
