clen doesn't require pct... just take 2 weeks on, 2 weeks off or pair it up with keto to clear your receptors... test... you don't really need that either although it helps men to keep your mass so you don't lose muscle... but not necessary just make sure your protein intake is increased while on it.... it's more for fat loss and energy... dose it low.... try it and see, all brands tend to be a little different...
