It cleans out the beta2 receptors which is what clen and albuterol act on. There’s another allergy med called ketotifen that some say clean out the receptor sites better, but from what I could see the only benefit it actually presents over Benadryl is aiding with Tumor necrosis factor which helps fight against cancer. But it’s expensive and Benadryl is hella cheap and easy to find.
2 weeks on clen. 2 weeks off, and take Benadryl before sleep on off weeks. Probably why I’ve never taken more than 80mcg of clen.
