40/40/40/60/60/60/80/80/80/100/100/100-taper back down and then back up for total of 6 weeks. Im going 6 weeks with the addition of yohimbine 20-30mgs a day to keep upregulation of receptor sites and prolong the effect of the clen. didnt want keto or benadryl, get too sleepy even with stimulants in my system. I guess since im doing the yohim do I really need to taper back off? give me your thought please. my research has led me to believe that it still is better to taper and ramp back up. but my first time using clen so i want some veterans to its usage.
