One thing I will say is British Dragon doesn't exist and hasn't for a while so I doubt you'll find any genuine Andropen on the market. And for BB purposes I wouldn't use either, Test E is supperior IMO
There both pretty much the same thing. Andro has some test ace wich is a short esther and gives you a quicker boost while you wait for the rest to kick in. Like Braven said, not sure if you can find the "original" version. However some others come pretty close.
Bro there's still some BD around but like the good bros said, its pretty hard to ge ahold of real shit now a days. I mean the vials didnt magically dissapear when BD ended. But there are no more being produced.
Check the security features of your vial:
The top stuck to the metal piece on one side
The dragon on the rubber where you inject the needle is visible
the BD security logo (the red or Blue design on the vial) is sticking out a little bit. ETC
IMO andropen is superior to Sust just cuz of the test acetate and the test cyp. Everything else its the same.
