In my experience I've had a puffy/swollen nip on several large dose cycles (test, tren). For some unknown reason its always the left nipple, but it always goes away with either some aromasin and nolvadex or if I drop the gear altogether it goes away. Been off cycle for almost 2 months (about 1 month since PCT) and zero puffyness.
Also, coincidently, whenever I started taking stanozolol tabs its seems to go down a bit too but it could also be that I usually take Tren and Test and then stop it to run the stanz... so not sure if its due to halting the tren ace Test stack or taking stanz.
Maybe a combo of both.
