I'm on a tren and test cycle and a nodule (lump) appeared on my left nipple and it is extremely sensitive. Already had that before on a previous cycle; so started taking 1.25mg liquid letrozole every third day to see if it recedes and goes back to normal. This is the first time I'm using letrozole as anti-estrogen, used nolvadex (tamoxifen) before and it worked well. Will do nolvadex for PCT this time.
Any thoughts or opinions?
