More than words can explain!!! I run npp with every cycle and I will NOT touch Deca again... U have the same compound but put into a lot shorter ester. Yes u have to pin more often but u don't experience the extreme gyno or water retention like u do with Deca IMHO! That's according to my history tho!! I love npp! And the recovery is so much easier with its half life being way shorter... Run the npp and I guarantee u won't touch Deca again
4.5 day half life vs. a 2 week half life. and deca esters do stick around way longer than half life, don't let that fool you. deca will stick around 5 weeks after last injection in small amounts. its a stubborn ester
