Alright guys, long story short, it's my second cycle of MK-677 and today, without any warning, I had some sensitivity/pain when pressing my left nipple (the gland under it..). I have ran MK-677 for 2 months ½ and I had no issue before. The only thing I added this time was Allmax Whey protein (i wasn't using whey because my diet had already a lot of proteins in it.). Could it be prolactin level going out of whack or even the MK-677 that got mixed with prohormones? Also, I have no PCT on hand, only some AI like Apigenin.
