It is clearly not healthy, I do not advise it but - 2,5 - 5mg pharma letrozole killed my lump. Continue taking it a few days after the lump subsided and slowly taper down the dose.

How long were you on the prop? Taking anything else? Dosage? PCT? Did you use any AI? Need some more info

20mg nolvadex until lump is resolved

I think there's stuff on eroids about gyno treatment protocols (even not real gyno, but a lump like you have) - just use the magnifying glass at the top to search.

U can try to fix it, but if u don't get it resolved quickly, u need to see a doc. The longer it sits around the less likely it is to resolve with your own treatment.

You're going to need to amputate that nipple. It's the only solution nip.

First off bro you should have had pre during and post bloods. Mid cycle bloods to see if estro was out of whack so you could have prevented it from the start.... this is why you research what you are doin before you do it. Now that you have stopped the cycle estro rebound is a possibility. Do have an AI on hand? My guess is no. Go to the doctor be honest and next time be prepared bud.

At 25 go to the Dr and be honest
