Way too much thought going into this. Your dietary supplements will be fine in the original packaging(halo,UM,ACS). Your SERM should be fine as well if it is unopened but if it makes you feel safer just put it in a small unmarked travel type plastic bottle in your checked luggage with your toiletries. The TSA has swabs that will let them know if it is a suspicious substance or not......which it most certainly isn't. Worst case scenario is they confiscate it but I highly doubt that will even happen. Remember a SERM is not a scheduled substance.
