Mexican brand nolva

My source sells his nolva loose in 100 ct. bags. I asked the brand and he said hes not sure but he knows its mexican. can anyone name some known nolva/tamoxifen that comes out of mexico? I want to try and identify mine. Ill post a pic later if i can. Thanks

i bought some from an online pharmacy and it says tamoxifen, then some stuff in spanish, no brand name though.
