Clenbuterol and ephedrine are both beta2 adrenoceptor agonists, although clen is much stronger than eph in this respect it would definitely be a bad idea to use eca when u come off of clen as your beta2's will not be allowed to recover. I have done both together but the sides are intolerable for alot of people and can be dangerous if the dosages get too high, and this varies from person to person.
You should run a 2 week clen cycle and stay off for atleast 2 weeks, no other stims while off. Just use L-carinitine and cla while off. If you find some ketotifen to use while on the clen that will allow you to run the clen longer since it does well with the re-uptake of your beta2 adrenoceptors. You can run it up to 6 weeks with the keto, some people can only get 5. Start it after about 10 days of the clen and run it til the end of the cycle. Look up proper dosing protocols if you've never done clen before, I wont get into all that now.
