No, it's not the name of my heavy metal garage band. I'm making this thread because this issue has me stumped and nowhere I look can I find a convincing answer. I received a big shipment of raws last year. Everything seemed fine, I didn't plan on brewing anything as of that moment so I kept the raws in my source's original packaging and dropped it all in my cupboard. At the time, some sustanon as well as a one or two other items came in a gooey, oil like substance rather than powder. I figured it was no big deal and just a product of the stuff melting during delivery. But now after a few months I check on my stuff and everything seems fine except for the Sustanon. It turned a strange dark amber color. This has never happened to me before. Should I be concerned?
