Both are phenomenal products! Thai Bayer Testovirons however have been discontinued for the past two years, (Not sure when new lots will he back, hopefully soon) but send a message on the site we might still have old stock left. As for Rotexmedicas, they are still in production and in fact we have access to fresh lots. Again, send a message on our site so we can update you swiftly on current stock. I hope all is well, stay safe.
