(sorry for the repost but i put this in the SARMS section about two days ago and no reply) i put in a search for arimidex in arr and it came back with letro so i quickly purchased it bcuz i only had about 2 mins left before the 20% off sale was over...after i purchased i put in an search for adex and it came back with a tamox...i assumed when u guys mentioned adex u were shortenin it for the word arimidex...is letro a good ai or is tamox the more commonly used one...thanks
