It was recommended by Swale who is an hrt doctor, to run it at 250-500iu 2x weekly. But that being said, I dont know if you would need it during a 4 week cycle
If gaining all year with slow steady gains with hardly no down time is what you are looking to do then shorter cycles with little time off is the way to go. Yes they will shut you down but the goal while doing them is to keep sending signals to your hpta using clomid, nolvadex, hcg is used to do this. Also when you are ready to take a break for several months your not going to crash hard like you would a long cycle.
Keep in mind if you are into doing the short cycles then faster action gear is best and higher dose then you would use durring a 10-15 weeks cycle.
