PCT is post cycle treatment, Nolvadex. so i would run single ester test for 12 weeks then stop and start the winstrol for 4 weeks than stop and run the test for 2 more weeks? then run Nolvadex? Does using the test before the winstrol prevent me from shutting down? And i am sorry in advance i have many questions... i dont want to just jump into anything i want to take my time and do it right.
