DECA Nandrolone Decanoate FAQ
**How does DECA compare to NPP (Nandrolone Phenylpropionate)?**DECA has a longer ester (8-10 days vs 2-3 days), requiring less frequent injections but taking longer to clear the system.**What’s the optimal DECA to testosterone ratio?**Most users find 1:1 to 2:3 (DECA:Test) ratios work well, such as 400mg DECA with 600mg testosterone weekly.**Can DECA be frontloaded for faster results?**Yes, using 1.5-2x the weekly dose in week 1 can accelerate onset of effects by 2-3 weeks.**How do I know if my DECA is legitimate?**Legitimate DECA should improve joint comfort within 4-6 weeks and show muscle building effects by week 8-10.**What’s the best post-cycle therapy after DECA?**Extended PCT with hCG bridge followed by 6-8 weeks of Clomid/Nolvadex due to DECA’s long suppressive effects.
