Just for context, you’re aware the joint benefits given by nandrolone aren’t permanent right? I took it once (NPP) for about 3 wks (or was it four weeks, I’ll never remember the exact amount of time, probably somewhere in between 3-4wks), joints felt great, three weeks off it and everything was back to normal.
The benefits one gets with regards to joints from nand probably isn’t from collagen synthesis, otherwise oxandrolone and stanozolol would also be known to help with joint pain. Nand is likely anti-inflammatory and/or increases pain threshold in some way or another. But who knows, not enough research
If you’re in a lot of pain, go to a doctor/ physiotherapist and see if there’s anything that can be done, if not (or the only solution is painkillers) then you can look for alternate avenues.
I know joint pain can be a real pain in the ass, however it’s always best to see if there’s a non pharmacologic option that can be taken, potential long term effects from nandrolone are numerous (and in general nand is just riskier than testosterone), have you taken it before (just curious)
