I got a couple boxes of pharm grade nolva tabs that have passed expiration. One expired Feb 2011 and the other sometime in 2012. I understand the 2012 one is prob ok but was wondering if the other is ok to use? Regardless, there's only 15 tabs left. If it loses a little potency over time it shouldn't be much of a worry since this will be used with clomid for test 500mg cycle w/hcg.
