Never tried it personally, I know a lot of guys who've got really big running test and deca cycles over and over again, I also know a couple of guys who've ended up with long term erection problems (in their early 30s) due to the misuse of this drug... Personally I've done a lot of reading on this and am put off by the potential for sexual sides and harsh recovery that many people experience... I may skip Deca altogether and see how Tren treats me for my next cycle...
