I ran that letro protocol with very good results. I have some from when i was a kid so need to take my AI higher then what may be considered norm. As soon as I feel puffiness or to much soreness I start slowly increasing my AI which is adex atm.

I dont think people can just say some puffiness is normal if they dont understand who may be more sensitive to estro or gyno symptons.

In the end if you are prone to gyno the only real way to get an accurate ai dosing is by taking it and getting bloods throughout cycle. I get bloods every 2-3 months and every month if I run into issues.

Good luck!

Cry havoc is telling you correct. Here's the protocol that has been used and works. It's based on three different Scenarios. Another thing Letrozole will suppress your sex drive.. Just letting you now.

looks like solid advice down below brother, keep us updated on how this turns out in the coming weeks.. for me personally I like aromasin over adex.

Having gone through a letro regiment for hard painful lumps I can state the following:
1)No they will not go away. The pain will go and the puffiness will go but the lumps will merely shrink down to something on the scale of a pea. The good news is that you will not know they are there without some serious twisting mashing on your nipple to find it.

2) It takes at least two weeks for letro to start taking effect and you should maintain the letro course for a period of 1-2 weeks after you have noticed the lumps and pain gone. This depends on your body fat.

3) I started at .25 the first day and increased it by .25 until I reached 2.5 a day and decreased it the same way.

4) Letro Will rebound so you must have another AI like adex on hand to prevent this, I have successfully come off letro during PCT with nolva and clomid with no rebound.

5) Letro will dry the shit out of your joints.

Hey brother , first of all glad to see you are back.I just wanted to touch upon an experience i had long before I began using aas. About four years ago i had a serious gastrointestinal infection.I was given some strong antibiotics in the beginning and then another named METRONIDAZOLE,I was on it for a very long time while i went through several diagnostics to try and pinpoint the root cause.After about 6 weeks on the shit i began to get puffy nipples and they began to feel sensitive.Im like what the fuck , so i told the doctor that something wasnt right and told her of my concerns, she basically said its a side affect and the positives of that medication was greater in treating the infection, then dealing with the aesthetic sides.I went and did some research on my own and found out that this antibiotic can in fact cause Gyno or the growth of breast tissue in men.I had some friends that used at that time so i got some nolva and began taking it asap.I wasnt on any gear before and just ran it like a pct protocol,40/40/20/20. That did the trick and soon therafter i was off the Antibiotics.In the time that i was researching this I learned that many prescribed medications can in fact cause or attribute to the growth of breast tissue.I read in one of your posts that you were taking some forms of medication,some types of anti-anxiety and psychotropic drugs may also contribute to gyno as well.I dont know what you were taking but i just thought of my experience and i wasnt sure if many people are aware that some meds they take on a daily basis can lead or contribute to gyno themselsves, thats not taking into account the compounded or synergestic effects that could arise if one is taking these types of medications and then continuing or dropping the meds and starting the use of anabolic compounds.As i am not sure of half lives of the medications that can contribute to or may cause Gyno themselves It is pretty difficult to state for certain . I have never tried the Letro protocol so i cant really offer much in regards to that,My words may of be no value brother, But after reading your posts and it seemed you had all your bases covered and you still had a problem arise in regards to gyno, which led me to think that there might be an issue with an unknown, which could possibly be certain meds that you may have been taking long before you began your cycle.Just sharing my experience and hoping you can get to the bottom of it bro.

what are your stats, its easier to address these issues when we have an idea of you, and what your running.
age, sex, weight, what and how much youre running. even AI
