I covered both bases tho. I always felt kind gross on it. Deca Durabolin has a very long half-life of up to 16 days. Don't get much strength from NPP (compared to deca) but hell of a lot of size quickly. NPP - Nandrolone Phenylpropionate - Nadrolone compound suspended in Injectable Deca Durabolin for sale online in UK quick acting ester. And the people I've talked to still say Deca is superior for muscle gain despite the same parent hormone, just different ester lengths. I started alpha north anavar after christmas to get myself back in shape for 2020. The steroid increases protein synthesis and nitrogen retention in the muscle tissue which results in incredible Deca gains, Deca Durabolin.
