Ok, so after some research I noticed the following differences, however I am still confused about switching from Clen to Ephedrine to allow a correction of beta receptor down-regulation. The reason being that it looks like Ephedra has some effect on beta receptors, but not as much as Clen. It should still be effective on a (2-week Ephedrine)/(2-week Clen) cycle?
Ephedrine:
How Does Ephedrine Promote Fat Loss?
Rather than working directly itself at fat cells, ephedrine acts as a sympathomimetic to activate their beta adrenergic receptors, thus stimulating lipolysis and metabolic rate and reducing appetite. All these work together to improve fat loss....
All this is effective in stimulating beta receptors, though it?s not as effective as stimulating them directly, as albuterol and clenbuterol do...
There are no or little issues with receptor downregulation and ephedrine need not be cycled for that reason.
Clenbuterol:
Clenbuterol (Spiropent) is a beta-receptor agonist
Clenbuterol should be cycled rather than used continuously or for prolonged periods of time, but no exact cycling pattern is necessary. Period of use is typically from 2 to 8 weeks.
Periods of use such as 2 weeks or more at doses much in excess of 40 mcg/day results in desensitization. This can be avoided by taking 1 mg ketotifen once per day, preferably prior to retiring.
