I was reading about beta agonism and aspirin and caffeine's role.
I know Clenbuterol is a more powerful beta agonist than ephedrine is. I know from personal experience because I lost more fat from Clen alone than with ECA.
However, 2 things I read that interested me. Caffeine supposedly helps prevent the breakdown of C-AMP and Aspirin supposedly inhibits negative feedback from beta agonist production from ephedrine. It goes to figure that Caffeine should still prevent the breakdown of C-AMP whether taking ephedrine or Clen. It also goes to figure that Aspirin should inhibit negative feedback from Clen just as well as with ephedrine (though Clen being more powerful, perhaps a higher dose would be needed).
So that got me thinking, if that IS true, then perhaps taking Clenbuterol + Caffeine + Aspirin would be even better than Clenbuterol alone. It'd be like super ECA. Of course, it would only work for 18 days, but in that time, I wouldn't be surprised if fat loss results would be greatly magnified.
