ephedrine on beta receptors

[John Smeton]

Patrick, Do you share Dr. Scott Connelys view the ephedrine is good for muscle building on beta receptors?

[staple]

just in case patrick is not familiar with his views, can you post it here? or a link to it's overview?

[Patrick Arnold]

is ephedrine good for muscle building in a fashion similar to clenbuterol? That is an interesting question. I have always thought it could share at least some of the muscle effects of beta2 agonists. Probably not to the same degree. Does Connelly quote any actual direct studies showing effects on muscle?

[Patrick Arnold]

ephedrine of course does not directly interact with beta2 receptors however it stimulates the release of catecholamines that do

I think there was a whole episode of bodyrx where he discusses it.

this I heard it on a radio show over at rx muscle and he said he took the stance ephedrine does build muscle.

1R,2S-ephedrine is a potent direct beta receptor agonist.

and u stayed awake through the whole thing?

is that the one in synthetic ephedrine tabs?

Yep

Good read madchemist thanks, now...PA thoughts? and also yours madchemist, good way to dose and use for muscle building goals? Worth it? Realistic?

I listen to hear what Vince has to say lol.

madchemist is the neuro guy so i will let him handle this stuff

Most of the studies which show anabolism from clenbuterol in animals use doses that would be intolerable (i.e. side effects) in humans.

However, there are some human studies which show an increase in lean muscle mass from clenbuterol in patients utilizing a ventricular assist device - not very generalizable.

Furthermore, it would be hard to extrapolate the physiological effects of clenbuterol to ephedrine since their kinetics are so different (36 hour half-life versus 3-5 hours, respectively).

I've not really explored this topic in depth, so correct me where I am wrong.

i retired from that show a long time ago. i dont wanna talk for two hours on what the best ratios of branched chains are. or how much protein you should eat at night.

so many subjects i thought coulda been discussed. but connelly called the shots and he would only talk about what was in his comfort zone. i didnt really have that much to offer on those subjects, nor was i enthusiastic about those subjects, so i split that scene

one thing i know is the anabolic effects of beta2 agonists in animals are rapid and profound, but dissipate after a short period of time

i mean they actually reverse after a period of time.

Well this pretty much throws it off the rack then haha, I can not bring myself to picture someone so desperate to use Clen, to build muscle, with a VAD be it R/L/ or BiVAD haha, but then again...Human kind never ceases to surprise me with their occurrences. And yeah as for the half life of ephedrine, I guess it would be hard to make assumptions on such different kinetics as you point it out. Aw well, ephedrine will remain part of my cutting arsenal only then.

Right, receptor downregulation.

The medical world has explored the reverse, mostly in the context of congestive heart failure.

Beta1 blockers result in cardiac beta receptor upregulation, whereas alpha/beta blockers (labetalol) do not.
