no, not necessary... in 4 weeks it will not have enough time to make any significant impact on estrogen.. its when people abuse the dosing and run it too long or too high.. if you follow how i recommend to dose it, you will have no issues bro
is this enough dosage for increasing LH before pct ? why we shouldn't run it on cycle in small dose for preventing testicle atrophy ? or isn't better to run it after last injection on 1000 iu in 11 days straight ?
im lost here.. 4 weeks at 1000 ius week is MORE THAN ENOUGH for what you need to transition into pct... you can run it all cycle if you want man but dont be shocked when you have issues later... hcg is suppressive, increases estrogen and causes other functional issues in you when you run it too long... you can run it however you like but i know how to use it properly to get what you need out of it without hurting yourself in any way
So hcg should only be run on ur last weeks of cycle leading up to pct? What about guys who use HCG for fertility maintence during there whole trt cycle at say 1000 ius a week
