clenbuterol can cause a downregulation in testicular androgen receptors and in pulmonary, cardiac and central nervous system beta-adrenergic receptors making
clen less effective as time goes on. to counteract this you can take some ketotifen or periactim every 3rd or 4th week that you re on
clen.
another option is taking benadryl at around 50-100mgs/night before bed. benadryl slows desensitization of beta receptors by inhibiting phospholipase a2. this keeps the phospholipid membrane stable and receptors functioning properly. this will allow you to use
clen for much longer and still have the same effects.
