TweetI've never had the npp ester. But Deca/test is my normal cyle. I get great strength and mass gains with almost no sides(maybe a little night sweats) I've never got deca dick. I hold some water but it's not just sloppy weight like on anadrol and if I add in mast. at the end it gets rid of the water and increases my strength. It's much easier for me to deal with than tren. My joints feel good and just feel good in general, tren gives me awful insomnia and while the gains are great I'm ready to be off of it when the cycle is over.
All in all to me tren is very lean gains and awesome strength. Deca is slow and steady gains and needs to be ran a long time but, when it kicks in the strength and mass gains are great imo. Both have their place just work differently for me.
