They are all the same, the only one that I have used are IP's (which was in my opinion underdosed, or maybe only prop) and omnadren, and I like the omna's better.
I love TTokyo but I don't play with their Testonon.
I like Durateston alot.
I have had bad sides from Omna.
Cytahoh was pretty good
Redijects are by far the best though.
Anyone used Organon's sust? I've used russian sust250 from infar got great gains from that, and am currently using TT testenon. At first it didn't really hurt. Just a strange sensation in my thigh. But now it's ok. Hopefully it won't be too sore tomorrow. I have a lot of running to do.
