Serge or whatever th f*k you call yourself. I only speak if i can add usefull feedback. I have been training and J**ing for over 10 years. This year is my first using ARIM, with great success. Now listen SERGE, i can tell you that in my experience it limits gains regardless of estrogen or not...In comparison to my previous cycles i noticed that i have not acheived the same muscle gains as in previous years....Learn,Listen and them Sh*t the F*k up and listen again. Its apparent that you are a newbie to this sport...HUCK, out of respect i say no more.
