i used tren for thr first time last cycle. was 175 prop/350 tren/ 500 mast p. i ran this for about 8wks then switched to long esters and dropped the mast. i quickly developed some gyno which letro and prami did nothing for. as soon as i droped the tren it quickly went away. this was real gyno, hard painfull lumps. not just some puffy nips. im using 350 prop/350 trenA/350 mast p for the last 3 1/2 weeks. im using 25mg exemestane and worked all the way upto 3mg caber. the lumps i have now are very small but slightly sensitve. seem to be under control tho. why does this happen?
