IGF-1 cycle

Hi guys,
Today i am entering my fourth week of my iGF-1 LR-3 cycle.I chose to run it cause i' on PCT too.so as to keep my gains and possibly recover faster.Before i was on TRT about 125mg/week along with two shots of HCG about five months and on gels+HCG 3 times a week ,not at the same time though.Since i am secondary due to overtraining,prolonged caloric deficit, i Under stand that i must run nolva for extended period,now i am on 40mg/day for a month till now.
Since from most i've'read iGF-1 must not be used more than four to five weeks.You are 4-5 weeks on and 4-5 weeks off .
My worry is that i don't want to stop so early the additional assistance IGF-1 provides me ,i 'm only one month on nolva,but on the other hand i don't want to mess with downregulation issues that may occure if i go above 6 weeks on iGF-1.
I'm doing about 40mcg 4 days a week.
What do you guys think to run when finished with IGF-1 so as to take the safe break and if like come back after with another IGF-1 cycle.Growth hormone maybe,for how long just to pass the 4-5 weeks off,what doses?
I would greatly appreciate your thoughts,recommendations on this.
Please pay attention on this.
THANKS.
