hey man, I've just finished running the Medistar Sustanon 250 and PCT with their Nolvadex/Arimidex, and yes, all caps are white - with white powder - mine were all sealed and looked suspicious, but don't worry they're good...Just wondering if you started the TNT yet as I'm thinking of running it in the fall...heard other brands - not medistar are painful with TNT400..any pains with this? .thanks man!
