What's your plan ??
Are you bulkng or cutting ??
As Sanish has mentioned below, whats your experience w/NPP, your dosage, and your frequecy of dosing ??
Npp, being a short ester, has a half life of only 72hrs. However, weather it be a bulker or cutter, you should see sides early in your cycle. Remember, NPP will not bloat you as as much as DECA but you will see a increase in strength and will increased prolactin levels thus possibly affecting ones libido.
Again, bottom line is how are you using it, @ what frequency, and what's your dosage.
