Quote from clen profile on this board..."Clen vs. clen+ exercise produce roughly the same results for the first 2 weeks! This tells me that the 2 weeks on and 2 weeks off schedule for clen dosing is far from optimal, and if you want the quasi-anabolic effect from the clen, it´ll take more than 2weeks on (6 weeks apparently). In addition, since clen alone is similar to clen+ exercise for those first 2 weeks...why would you ever use a 2on/2off protocol?"
but like Vinlander said clen stop working after about 2-3weeks because Clenbuterol causes a downregulation in testicular androgen receptors and in pulmonary, cardiac and central nervous system beta-adrenergic receptors. However, you can counteract this by taking benadryl which works by reducing beta-2 receptor activity, and restoring receptor function. Take the benadrly at nighttime(causes drowsiness) around week 3 and it will keep the clen working.
I hope this helps! GL
