what's wrong with clen? or if you are doing the 2 on and 2 off method with your clen why not do an ECA stack on your two off weeks of clen? you can order pure ephedrine for like 20 bux a box of 24 tabs.... then caffeine for like 10 bux... and baby aspirin for under 10 dollars... that is what a lot of people run on their 2 off weeks of clen.... very effective. OR run clen all the way through and use 50mg of benadryl every 3rd week for 7 days (night time before bed is best)
