Ok, as it says in my sig. this is my personal experience, different thigns work for different people, everyone must understand that. Anyways here is how I look at it. When you start to develop gyno, you are past the itchy or puffy stage and you actually have a lump under your nipple there is NOTHING nolva can do. Nolva is a selective estrogen receptor modulator, so if you have developed gyno how can nolva possibly get rid of it? All it does is flood the receptors so no more estrogen can get in, it does no inhibit estrogen or destroy it. So yes you can up the nolva dosage to 40mg or 60mg ED, but that will only help to block the receptors to a greater degree so your gyno doesnt get worse, but will not help the lump subside.
Letro is the only drug I know of that has the ability to reverse a case of gyno. It is an AI (aromatise Inhibitor). This means is inhibits the production of estrogen in your body, some people (including myself) use this instead of nolva on cycle because it inhibits the estrogen and doesnt just merely flood the receptors. Letro is stronger than both arimidex and aromasin in terms of AI's. It will block 98+% of estrogen. With no estrogen there can be no estrogen or progestin related sides.
Now in terms of reversing your gyno you will want to run letro at a higher dose than people use as maintenance on cycle. The dose I have run to reverse gyno is 2.5mg ED, this took about a week to 10days to reverse until the lump was completely gone. You cant just get letro and start taking it at 2.5mg ED tho, at least I dont suggest it. You need to taper up by about .5mg ED from .25mg until you reach 2.5mg. Run it at that dose until the gyno disappears and then for an extra few days to be sure all traces are gone. Then you can taper back down to .25mg or .50mg and remain at this dose for the remainder of your cycle until you start PCT. Good luck.
