Sorry to be the one to say it but your doctor cannot tell you that "you'll be back to normal within a month". Thats impossible for anyone to say since everyone's body responds differently. Some guys can follow a perfect first cycle and pct and still be unfortunate enough to get permanant shutdown, needing trt for life. I'm not saying thats you, but I would still urge you to get bloodwork done to know your levels. Shutdown is shutdown and thats what you went through on your cycle. A pct would be in your best interest and I would say bloodwork is necessary.
