I have dealt with gyno for quite some time as I developed it in puberty. I once thought it was pseudo, but realized when I hit 168lb at ~9% that it was actual tissue. I tried nolvadex, it worked while it was in my system, but as soon as I came off my newly up regulated progesterone receptors made me puffy from prolactin. So tothat I purchased three bottles of formastane, my first bottle was .
The product works great, dried me out, shrunk my gyno a tad bit and had me feeling great, only negative I can add is the price. I can't say what mg dosage I was using since my pump wasn't uniform. So my 200mg might have been 300-400mg.
That was working rather well but I ran out fast so I used some formastanzol for 3 weeks or so, this does not work all that well as the carrier seems to not permeate well. I didn't have the same rush that I had with formeron, and I wasn't as dry. So I purchased some during it's presale price.
The formasurge, although extremely runny and greasy initially, it dried me out incredibly fast. My gyno/nipples shrunk to nearly nonexistence haha. My libido stayed normal, no shutdown, and my joints seemed to compensate for the AI effect.
So before you jump into purchasing letrozole, please try out a cycle.
