Also if he feels he is getting great results from Tren and wants to add 1 (total of 9 weeks of tren) more week he would be able to.
It's also more of being accurate on the start of PCT, becuase if he is running tren on week 14 (which ends a day before his PCT and it should be at least 3 days)and by the time he starts his PCT he will still have Tren in his system.
