And this question comes up many times. (I'm currently creating a thread on NPP, so watch for that.)
NPP isn't comparable to prop in terms of injection site soreness.
IMO, tren or prop are probably the worst for injection pain. (prop will produce swelling, and extreme soreness... until one is use to it)
NPP on the other hand is a little different. NPP will STING while you inject it very badly. I find it to be one of the most painful injections. However, the next day, unlike prop I have zero soreness.
Hope that helps.
(p.s. most NPP is dosed @ 100mg/mL... generally nothing over 150mg/mL or it won't hold.)
