I got this oral gear I picked these up about a year ago from a friend who got them on a site here. It was listed as oral masteron. It is dark purple standard British Dragon square pressed tab stamped BD on one side and 50 on the apposing. I contacted him recently to verify what that is. He told me it's BD mesterlone. The discrepancy is that it's they are dark purple and BD mesterlone is blue. I cant find that color anywhere on any site or product review. I'd like get some feedback.
