I have tried mag 10 by biotest which is a great pro hormone. It contains two androgens A1-E and 4-AD-EC.
It is so good that biotest have been told to stop making it but you can still get it. It was about 100 for a two week cycle but I have seen it going for 45 from here

I easily moved from 15 to 16 stone with it.
