I've run Clen in the past and absolutely love the stuff. I've generally done 3 to 4 weeks supplementing with taurine and benadryl.
With that said, it is thought that clen interferes with T4's conversion to T3 which impairs your thyroid's normal functioning (hence the Clen/T3 cycle). Do any of you see it necessary to run any sort of PCT with thyroid normalization in mind?
From my understanding, the thyroid is extremely resilient, but I'd just like to hear other's opinions.
