I have another question. If modafinil is a selective alpha-1 agonist, is there anything I can take to up-regulate the alpha-1 receptors so that the modafinil does not lose its effectiveness over time?
Also, since clenbuterol is a beta-2 agonist, would it really make a difference if I take modafinil and clenbuterol together, or is this just not a good idea? Also, is there anything besides Benadryl that I could get without a prescription to up-regulate beta-2 receptors? Or, is Benadryl the best option without a prescription? I know that there's Ketotifen, but that requires a prescription.
Another question......which receptors does caffeine down-regulate?
