I been on a test e cycle for a month @ 500mg/week and I have not used an anti-estrogen. I was getting advice from someone on a website who seemed to be giving good advice and I thought I didn't need an anti-estrogen until after for post cycle therapy (pct). Now, I am pretty bloated got a bit of puffy nipples. I'm not sure what anti-estrogen to get, nolvadex is the most accessible to me atm, I could probably have that by the end of the week. I read somewhere I need ariminidex. Does it matter?
