Hello I am a newbie to posting here. My stats are 27 years old 195 weight 5ft 11 in tall, bodyfat 14%. Im currently taking 500 test p 10 weeks 500 of npp 8 weeks. Im in about week 5 now. I started having a lump behinded my right nipple. I started taking letro thinking it was coming from the test. been taking it for about 15 days now the lump is flatter but wider now. I start looking on here and I realized if its from the npp letro wont help. I seen ppl suggest caber but i couldnt find dosage i should take. If anyone could help I would be very thankfull.
